[0041] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to the implementation requirements.
[0042] Continue to refer Figure 2 , shows a process 200 of some embodiments of the service writing method according to the present disclosure. The service writing method comprises the following steps:
[0043] Step 201: In response to receiving a service write processing request, query whether there is a service write request processing result corresponding to the service write processing request in the current cache.
[0044] In some embodiments, the execution subject of the business writing method (for example, Figure 1 The terminal device shown in the figure) can respond to receiving a business write processing request and query whether there is a business write request processing result corresponding to the above-mentioned business write processing request in the current cache. Here, the business write processing request may refer to a request to write business data. For example, a business write processing request may refer to a request to write business data to the cache. For example, business data may refer to business information of an acquiring business / order business. For example, the business data may be the order information of a user, and the corresponding business write request processing result may refer to the result of order information processing (for example, the items corresponding to the order information have been shipped, including the shipping order number, shipping warehouse, shipping time and other information). The current cache can cache the processed business write request processing results. For example, the identifier of the business corresponding to the business write processing request can be used to query in the current cache whether there is a business write request processing result corresponding to the identifier.
[0045] Step 202, in response to not finding a business write request processing result corresponding to the business write processing request, generate a business write request processing result corresponding to the business write processing request, and synchronize the business write request processing result to the corresponding message topic in the message middleware.
[0046] In some embodiments, the above-mentioned execution subject may generate a business write request processing result corresponding to the above-mentioned business write processing request in response to the failure to find the business write request processing result corresponding to the above-mentioned business write processing request, and synchronize the above-mentioned business write request processing result to the corresponding message topic in the message middleware. That is, the above-mentioned execution subject may process the business corresponding to the above-mentioned business write processing request to generate a business write request processing result. For example, when the business corresponding to the above-mentioned business write processing request is order information, the goods corresponding to the order information are shipped. When the business corresponding to the above-mentioned business write processing request is an acquiring business, acquiring processing is performed.
[0047] That is, the execution subject can synchronize the processing result of the business write request to the corresponding message topic in the message middleware in the form of a message body (MQ message). The message middleware can be a pre-set message middleware. The message topic can be a topic corresponding to a certain business.
[0048] Step 203: Write the processing result of the business write request into the cache according to the business identifier corresponding to the business write processing request.
[0049] In some embodiments, the execution subject may write the processing result of the business write request into the cache according to the business identifier corresponding to the business write processing request. Here, the business identifier corresponding to the business write processing request may refer to the identifier of the business corresponding to the business write processing request, which may uniquely represent the business. In practice, first, the business identifier and the processing result of the business write request may be combined into business write request processing information. Then, the business write request processing information may be written into the cache.
[0050] In some optional implementations of some embodiments, the execution subject may write the service write request processing result into the cache through the following steps:
[0051] The first step is to add the business information corresponding to the business write processing request to the business write request processing result. The business information corresponding to the business write processing request may refer to specific information of the business.
[0052] The second step is to map the service identifier with the service write request processing result to generate a mapped service write request processing result. That is, the service identifier can be associated with the service write request processing result.
[0053] The third step is to write the mapping service write request processing result into the cache and set the cache expiration time of the mapping service write request processing result. The cache expiration time may refer to the longest cache time of the mapping service write request processing result in the cache.
[0054] Optionally, based on the business write request identifier included in the business write request processing result, it is determined whether the data version number corresponding to the business write request processing result in the message middleware is consistent with the data version number corresponding to the business write request processing result in the cache.
[0055] In some embodiments, the execution subject may determine whether the data version number corresponding to the business write request processing result in the message middleware is consistent with the data version number corresponding to the business write request processing result in the cache, based on the business write request identifier included in the business write request processing result. Here, the data version number corresponding to the business write request processing result may be a version number that identifies the business write request processing result. That is, first, the corresponding business write request processing result in the message middleware and the corresponding business write request processing result in the cache may be queried separately through the business write request identifier. Then, determine whether the data version number corresponding to the business write request processing result in the message middleware is the same as the data version number corresponding to the business write request processing result in the cache.
[0056] Step 204, in response to determining that the data version number corresponding to the business write request processing result in the above message middleware is consistent with the data version number corresponding to the business write request processing result in the above cache, the business write request processing result is persisted to the corresponding business table in the preset database.
[0057] In some embodiments, the execution subject may persist the business write request processing result to the corresponding business table in the preset database in response to determining that the data version number corresponding to the business write request processing result in the message middleware is consistent with the data version number corresponding to the business write request processing result in the cache. Here, the business write request processing result may be persisted to the business table in the preset database for storing the business write request processing result.
[0058] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the business writing method of some embodiments of the present disclosure, the business data writing time is shortened and the business data writing success rate is improved. Specifically, the reason for the failure of business data writing is that the index update of the database sub-table is not timely. Based on this, the business writing method of some embodiments of the present disclosure, first, in response to receiving a business write processing request, inquire whether there is a business write request processing result corresponding to the above business write processing request in the current cache. Thus, it is convenient to write asynchronous business data when the business write request processing result corresponding to the above business write processing request is not included in the cache. Then, in response to not querying the business write request processing result corresponding to the above business write processing request, generate the business write request processing result corresponding to the above business write processing request, and synchronize the above business write request processing result to the corresponding message topic in the message middleware. Thus, when the business write request processing result corresponding to the above business write processing request is not included in the cache, asynchronous processing of business data is realized. Then, according to the business identifier corresponding to the above business write processing request, the above business write request processing result is written to the above cache. Finally, in response to determining that the data version number corresponding to the business write request processing result in the message middleware is consistent with the data version number corresponding to the business write request processing result in the cache, the business write request processing result is persisted to the corresponding business table in the preset database. In this way, business data can be written asynchronously and in real time without referencing the database sub-table. Thus, the business data writing time is shortened and the business data writing success rate is improved.
[0059] Continue to refer Figure 3 , Figure 3 The process 300 of some other embodiments of the service writing method according to the present disclosure is shown. The service writing method comprises the following steps:
[0060] Step 301: In response to receiving a service write processing request, query whether there is a service write request processing result corresponding to the service write processing request in the current cache.
[0061] Step 302, in response to not finding a business write request processing result corresponding to the business write processing request, generate a business write request processing result corresponding to the business write processing request, and synchronize the business write request processing result to the corresponding message topic in the message middleware.
[0062] Step 303: Write the processing result of the business write request into the cache according to the business identifier corresponding to the business write processing request.
[0063] Step 304, in response to determining that the data version number corresponding to the business write request processing result in the above message middleware is consistent with the data version number corresponding to the business write request processing result in the above cache, persist the above business write request processing result to the corresponding business table in the preset database.
[0064] In some embodiments, the contents of steps 301-304 are the same as the contents of steps 201-204, and are not repeated here.
[0065] Step 305: query the cache according to the service write request identifier to obtain a cache query result.
[0066] In some embodiments, the execution subject of the business writing method (for example, Figure 1 The terminal device shown in the figure can query the cache according to the business write request identifier to obtain the cache query result. The business write request carries the business write request identifier. Here, the business write request identifier can be the identifier of the business write request. That is, the business write request processing result corresponding to the business write request identifier can be queried in the cache.
[0067] Step 306: In response to determining that the cache query result is empty, query the preset database to obtain a data query result.
[0068] In some embodiments, the execution subject may query the preset database in response to determining that the cache query result is empty to obtain a data query result, that is, the preset database may be queried for the service write request processing result corresponding to the service write request identifier.
[0069] Step 307: in response to determining that the data query result is empty, re-execute the business write operation of the business write processing request.
[0070] In some embodiments, the execution subject may re-execute the service write operation of the service write processing request in response to determining that the data query result is empty. Here, the service write operation may refer to the description in steps 301-306.
[0071] from Figure 3 It can be seen that Figure 2 Compared with the description of some corresponding embodiments, Figure 3 In some corresponding embodiments, the process 300 of the service writing method can determine whether the service writing request processing result is written successfully through the data version number and the service writing request identifier, thereby ensuring the stable operation of the service system.
