[0061] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0062] like Figure 1 As shown, an embodiment of the present invention provides a service calling method, including:

[0063] Step 101: Obtain information for calling a service.

[0064] The calling service may depend on one or different dependent services, for example, calling service A depends on the address service, and calling service B depends on the query service and the address service. Since the processing process for each dependent service is the same, the following embodiments will only be described by taking the dependent service as the address service as an example.

[0065] The information of the calling service includes: any one or more of the IP address of the server where the calling service is located, the calling service group corresponding to the calling service, the dependent service identifier and the computer room corresponding to the calling service.

[0066] Step 102: According to a number of pre-configured routing rules, determine whether there is a dependent service group matching the information. If so, execute step 103; otherwise, terminate the current process.

[0067] In the embodiment of the present invention, the information of calling the service may be matched with each routing rule in sequence to determine whether there is a dependent service group matching the information.

[0068] If there is no dependent service group matching the information, information such as call failure may also be prompted.

[0069] Step 103: Determine the dependent service instance corresponding to the information according to the preset corresponding relationship between the dependent service group and the dependent service instance.

[0070] Step 104: Call the dependent service instance corresponding to the information.

[0071] In the embodiment of the present invention, the routing rules are configurable. If the dependent service group corresponding to the calling service needs to be adjusted, the configured routing rules can be updated. In the embodiment of the present invention, there is no need to manually modify the routing rules in the code, and there is no need to restart the application, which can improve the efficiency of service calling and ensure the stability of the service.

[0072] In one embodiment of the present invention, the dependent service group to which the dependent service instance belongs can be determined based on the computer room and city where the dependent service instance is located. A dependent service group can include one dependent service instance or multiple dependent service instances. The dependent service group can achieve load balancing through multiple dependent service instances and improve the stability and reliability of the service.

[0073] For example, the address service includes: an LH group and an MJQ group; the LH group includes an address service instance 1, and the MJQ group includes an address service instance 2 and an address service instance 3.

[0074] In one embodiment of the present invention, the information includes: the IP address of the server where the calling service is located;

[0075] Routing rules include: the correspondence between the server's IP address and the dependent service grouping.

[0076] The correspondence between the server's IP address and the dependent service group is different, and the routing rules to which they belong are different.

[0077] For example, in routing rule 1, the corresponding relationship between the IP address of the server and the dependent service group is shown in Table 1.

[0078] Table 1

[0079] The IP address of the server Dependency Service Grouping 192.168.129.106 LH Grouping 192.168.129.107 LH Grouping 192.168.129.108 MJQ Grouping

[0080] In routing rule 2, the correspondence between the server IP address and the dependent service group is shown in Table 1.

[0081] Table 2

[0082] The IP address of the server Dependency Service Grouping 192.168.129.106 MJQ Grouping 192.168.129.107 LH Grouping 192.168.129.108 LH Grouping

[0083] The embodiment of the present invention determines the dependent service group corresponding to the calling service based on the IP address of the server, so that the calling services on different servers can call the same dependent service group, and can also make the calling services on different servers call different dependent service groups to provide services externally. The calling services on different servers call different dependent service groups, which can avoid the influence on the calling service after the dependent service group fails.

[0084] In one embodiment of the present invention, the information includes: a call service group corresponding to the call service;

[0085] Routing rules include: the correspondence between calling service groups and dependent service groups.

[0086] In actual application scenarios, the calling service group to which the calling service belongs can be determined based on the city where the calling service is located, the computer room, the merchant number corresponding to the calling service, and other information. For example, calling service A is divided into Beijing service group, Shanghai service group, and Nanjing service group. Calling service B is divided into computer room 1 group and computer room 2 group. In an embodiment of the present invention, the calling service group in the routing rule can be identified by the name (or alias), number, etc. of the calling service group, and the dependent service group is similar.

[0087] In routing rule 3, the correspondence between the calling service group and the dependent service group is shown in Table 3.

[0088] Table 3

[0089] Calling Service Group Dependency Service Grouping lf_pc LH Grouping pc_mjq MJQ Grouping

[0090] In the embodiment of the present invention, the calling services belonging to different calling service groups can call the same dependent service group or different dependent service groups. The calling service can call the dependent service instance in the dependent service group in the same computer room or across computer rooms or cities. For example, the calling service in computer room 1 calls the dependent service instance in computer room 1 or the dependent service instance in computer room 2.

[0091] In one embodiment of the present invention, the method also includes: if there is no dependent service group matching the information, then according to the correspondence between the preset dependent service group and the dependent service instance, the dependent service instance corresponding to the preset default dependent service group is determined, and the dependent service instance corresponding to the call information is executed; wherein the dependent service instance corresponding to the information is the dependent service instance corresponding to the default dependent service group.

[0092] In order to ensure the stability of calling services, the present invention determines the dependent service instance corresponding to the information of calling services according to the preset default dependent service grouping, so as to ensure that stable calling services can still be provided when the routing rules corresponding to the information cannot be found.

[0093] In the embodiment of the present invention, the routing rules can be configured through the ZooKeeper service. Specifically, when monitoring configuration changes, the ZooKeeper client can monitor whether the routing rules in the ZooKeeper cluster are updated, and if so, update the local configuration.

[0094] The ZooKeeper service can be used to dynamically update routing rules. The updated routing rules can take effect immediately without restarting the application, reducing the impact on the calling process and ensuring the stability of the calling service.

[0095] In one embodiment of the present invention, the information further includes: a dependent service identifier;

[0096] According to several pre-configured routing rules, determine whether there is a dependent service group that matches the information, including:

[0097] Determine a routing rule corresponding to the dependent service identifier from among a plurality of pre-configured routing rules;

[0098] According to the routing rule corresponding to the dependent service identifier, it is determined whether there is a dependent service group matching the information.

[0099] Considering that there may be multiple dependent services, the embodiment of the present invention pre-configures routing rules corresponding to various dependent services, and the number of routing rules corresponding to each dependent service may be one or more. For example, the address service identifier is G, the search service identifier is H, the routing rules corresponding to G are G1, G2 and G3, and the routing rules corresponding to H are H1 and H2. If the dependent service identifier included in the information is G, then according to G1, G2 and G3, it is determined whether there is a dependent service group matching the information.

[0100] like Figure 2 As shown, an embodiment of the present invention provides a service calling method, including:

[0101] Step 201: Obtain the IP address of the server where the calling service is located.

[0102] In the embodiment of the present invention, the IP address of the server where the service is called is 192.168.129.106.

[0103] Step 202: Based on the correspondence between the preset server IP address and the dependent service group, determine whether there is a dependent service group that matches the IP address of the server where the calling service is located. If so, execute step 203; otherwise, execute step 204.

[0104] The correspondence between the server IP address and the dependent service group is shown in Table 1. The IP addresses of the servers where the calling services are located are matched one by one with the IP addresses of the servers in Table 1, and it is determined that the dependent service group corresponding to 192.168.129.106 is the LH group.

[0105] Step 203: According to the preset correspondence between the dependent service group and the dependent service instance, determine the dependent service instance corresponding to the IP address of the server where the calling service is located, and execute step 205.

[0106] Table 4

[0107] Dependency Service Grouping Dependent service instances LH Grouping E1, E2 MJQ Grouping F1, F2, F3

[0108] The corresponding relationship between dependent service groups and dependent service instances is shown in Table 4. The dependent service instances corresponding to 192.168.129.106 are E1 and E2.

[0109] Step 204: Determine the dependent service instance corresponding to the preset default dependent service group according to the correspondence between the preset dependent service group and the dependent service instance, and execute step 205; wherein, the dependent service instance corresponding to the default dependent service group is the dependent service instance corresponding to the IP address of the server where the calling service is located.

[0110] In the embodiment of the present invention, the default dependent service grouping may be an LH grouping or an MJQ grouping.

[0111] Step 205: Call the dependent service instance corresponding to the IP address of the server where the calling service is located.

[0112] It should be noted that the embodiment of the present invention only takes one routing rule as an example for explanation. If there are multiple routing rules, that is, the correspondence between multiple groups of server IP addresses and dependent service groups, then before obtaining the dependent service group that matches the IP address of the server where the calling service is located, it is necessary to match the IP address of the server where the calling service is located with the IP addresses of the servers in each corresponding relationship in turn.

[0113] like Figure 3 As shown, it is a class diagram of the service calling method provided by an embodiment of the present invention, wherein RPCFactory depends on RPCDefaultService and RPCMapService, and provides a method for obtaining dependent service instances.

[0114] RPCMapService encapsulates the dependent service instances of each dependent service group, where the key is the dependent service group and the value is the corresponding dependent service instance. In addition, other services can create attribute maps on their own.

[0115] RPCDefaultService provides a default dependency service grouping. The example provides a default dependency service grouping for the address service, and other services can create their own properties. RouterPowerConfig and RouterServerConfig encapsulate several routing rules.

[0116] In actual application scenarios, calling a service can call dependent service instances across processes or servers. During the calling process, the dependent service instance may be unavailable due to network problems. In view of this, an embodiment of the present invention provides a service calling method, such as Figure 4 As shown, including:

[0117] Step 401: Obtain information for calling a service.

[0118] Step 402: According to a number of pre-configured routing rules, determine whether there is a first dependent service group matching the information; if so, execute step 403; otherwise, terminate the current process.

[0119] Step 403: Determine the dependent service instance corresponding to the first dependent service group according to the preset corresponding relationship between the dependent service group and the dependent service instance.

[0120] Step 404: call the dependent service instance corresponding to the first dependent service group. If the call fails, execute step 405.

[0121] Step 405: According to a number of routing rules, determine whether there is a second dependent service group matching the information; if so, execute step 406; otherwise, terminate the current process.

[0122] Step 406: Determine the dependent service instance corresponding to the second dependent service group according to the correspondence between the dependent service group and the dependent service instance.

[0123] Step 407: Call the dependent service instance corresponding to the second dependent service group.

[0124] In the embodiment of the present invention, at least two dependent service groups matching the information can be determined by routing rules, and if a dependent service instance in one of the dependent service groups cannot be called, a dependent service instance in another matching dependent service group can be called. This method can ensure the stability of the service.

[0125] like Figure 5 As shown, an embodiment of the present invention provides a service calling method, including:

[0126] Step 501: Acquire information about a calling service, wherein the information about the calling service includes: an IP address of a server where the calling service is located, and a calling service group corresponding to the calling service.

[0127] The IP address of the server where the calling service is located is 192.168.129.106, and the calling service group corresponding to the calling service is qtrade_lf.

[0128] Step 502: According to a number of pre-configured routing rules, determine whether there is a first dependent service group matching the information; if so, execute step 503; otherwise, execute step 504.

[0129] The routing configuration of the present invention is as follows Figure 6 As shown, the configuration includes two routing rules, as shown in Table 5 and Table 6.

[0130] In an embodiment of the present invention, the priority of the IP address of the server where the calling service is located is higher than the priority of the calling service group corresponding to the calling service. Therefore, 192.168.129.106 is first matched one by one with the IP addresses of the servers in Table 5, and the first dependent service group matching 192.168.129.106 is obtained as a B2B group.

[0131] Table 5

[0132] The IP address of the server Dependency Service Grouping 192.168.129.106 B2B Grouping 192.168.129.107 B2B Grouping 172.17.23.28 YZ Grouping 172.17.23.27 YZ Grouping

[0133] Table 6

[0134] Calling Service Group Dependency Service Grouping lf_pc LF Grouping qtrade_lf LF Grouping pc_mjq MJQ Grouping qtrade_mjq MJQ Grouping

[0135] Step 503: According to the preset correspondence between the dependent service group and the dependent service instance, determine the dependent service instance corresponding to the first dependent service group, and execute step 505.

[0136] Table 7

[0137]

[0138]

[0139] According to Table 7, the dependent service instances corresponding to the B2B group are determined to be E1 and E2.

[0140] Step 504: Determine the dependent service instance corresponding to the preset first default dependent service grouping according to the correspondence between the preset dependent service grouping and the dependent service instance, and execute step 505; wherein the dependent service instance corresponding to the first default dependent service grouping is the dependent service instance corresponding to the first dependent service grouping.

[0141] The first default dependent service group is the SH group.

[0142] Step 505: Call the dependent service instance corresponding to the first dependent service group. If the call fails, execute step 506.

[0143] Step 506: According to a number of routing rules, determine whether there is a second dependent service group matching the information; if so, execute step 507; otherwise, execute step 508.

[0144] Match qtrade_lf with the calling service groups in Table 6 one by one to obtain the dependent service group LF corresponding to qtrade_lf.

[0145] Step 507 : According to the correspondence between the dependent service group and the dependent service instance, determine the dependent service instance corresponding to the second dependent service group, and execute step 509 .

[0146] According to Table 7, it is determined that the dependent service instance corresponding to the LF group is M1.

[0147] Step 508: Determine the dependent service instance corresponding to the preset second default dependent service grouping according to the correspondence between the preset dependent service grouping and the dependent service instance, and execute step 505; wherein the dependent service instance corresponding to the second default dependent service grouping is the dependent service instance corresponding to the second dependent service grouping.

[0148] The second default dependent service grouping is the BJ grouping.

[0149] Step 509: Call the dependent service instance corresponding to the second dependent service group.

[0150] In the embodiment of the present invention, the routing rules provide two routing methods, one is based on the IP address of the server where the calling service is located, and the other is based on the calling service group corresponding to the calling service. Therefore, when the network fails and the dependent service group in the first dependent service group cannot be called, the dependent service group in the second dependent service group can be called according to the routing rules. This method can ensure the stability and reliability of the service.

[0151] like Figure 7 As shown, an embodiment of the present invention provides a service calling device, including:

[0152] The acquisition module 701 is configured to acquire information of calling a service;

[0153] The determination module 702 is configured to determine whether there is a dependent service group matching the information according to a plurality of pre-configured routing rules; if there is a dependent service group matching the information, determine the dependent service instance corresponding to the information according to a preset correspondence between the dependent service group and the dependent service instance;
