Description

Technical Field

[0001] The present invention relates to the field of service fuse technology, and in particular to a service fuse method and device based on a Dubbo framework. Background Art

[0002] Dubbo is an open-source, high-performance service framework that enables applications to implement service output and input functions through high-performance RPC, and can be seamlessly integrated with the Spring framework. Fusing refers to the instability of a resource in the system call link, which may cause requests to pile up, leading to cascading errors. At this time, the unstable resources are isolated and fused, and for subsequent call requests, the target service is no longer called, and it returns directly to quickly release resources. Avoid the "avalanche effect".

[0003] The components such as Hystrix, resilience4j, and Sentinel supported by the Dubbo framework can all implement service degradation and circuit breaking, and support setting circuit breaking conditions in multiple dimensions, including the proportion of slow interface calls, the proportion of exceptions, the number of exceptions, and other dimensions. It also supports developers to customize the simulated return content. Once the circuit breaking condition is triggered, the pre-defined return content is directly returned, and the Dubbo service is no longer called. When the service is judged to have been restored according to the circuit breaking conditions, it returns to normal. However, the current Dubbo framework does not support manual control of circuit breaking. For example, it is currently impossible to manually temporarily circuit breaker a service. Therefore, the prior art Dubbo framework lacks a mechanism for manual control of circuit breaking. Summary of the invention

[0045] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0046] Those skilled in the art will appreciate that embodiments of the present invention may be provided as methods, systems, or computer program products. Therefore, the present invention may take the form of a complete hardware embodiment, a complete software embodiment, or an embodiment combining software and hardware. Moreover, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

[0047] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatus.

[0048] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this application are in compliance with the relevant provisions of national laws and regulations.

[0050] Figure 1 This is the first flow chart of the service fusing method based on the Dubbo framework in an embodiment of the present invention. Figure 1 As shown, in one embodiment of the present invention, the service fusing method based on the Dubbo framework of the present invention includes steps S101 to S103.

[0051] Step S101, intercepting the service request through the Dubbo filter.

[0052] In the embodiment of the present invention, the Dubbo filter intercepts every service request.

[0053] Step S102, reading the fuse switch parameter corresponding to the service requested by the intercepted service request from Nacos, wherein the fuse switch parameter is manually configured, and the fuse switch parameter includes: a first parameter value for indicating that the fuse is turned on. In one embodiment of the present invention, the fuse switch parameter also includes: a second parameter value for indicating that the fuse is turned off.

[0054] In a specific embodiment of the present invention, the first parameter value is on, and the second parameter value is off.

[0055] The present invention utilizes Nacos parameter management to save fuse switch parameters. Users can set fuse switch parameters corresponding to each service in Nacos and can change the fuse switch parameters. In addition, users can also add and delete fuse switch parameters in Nacos.

[0056] The present invention increases the fuse switch parameter through Nacos parameter management. When a method of a certain service needs to be fused, the corresponding Nacos parameter value is modified and the corresponding switch is turned on to achieve fusion. Thus, a manual control fuse mechanism is added to the prior art Dubbo framework.

[0057] Nacos is a dynamic service discovery, configuration and service management platform that provides three functions: registration center, configuration center and dynamic DNS service. It can seamlessly connect to popular frameworks such as Springcloud, Spring, Dubbo, etc. Nacos's functions include: DNS-based and RPC-based service discovery (can be used as a registration center for springcloud), dynamic configuration service (can be used as a configuration center), and dynamic DNS service.

[0058] Step S103: If the read fuse switch parameter is the first parameter value, a pre-set fuse measure is taken for the intercepted service request.

[0059] The present invention determines whether the service corresponding to the service request is within the range of the fused service interface by querying the fuse switch parameters. If so, a pre-set fuse measure is taken, otherwise, the execution continues.

[0060] In one embodiment of the present invention, the service fusing method based on the Dubbo framework further includes:

[0061] If the read fuse switch parameter is the second parameter value, the intercepted service request is processed.

[0062] like Figure 2 As shown, in one embodiment of the present invention, the service fusing method based on the Dubbo framework of the present invention includes step S201 and step S202.

[0063] Step S201: Monitor in real time whether the parameters of each fuse switch in Nacos have changed through a parameter change monitor.

[0064] like Figure 4 As shown, the present invention sets a parameter change monitor for monitoring whether the parameters of each fuse switch in Nacos have changed.

[0065] Step S202: If there is a change in the fuse switch parameters, the bean definition is reloaded to make the changed parameters effective.

[0066] The present invention utilizes Nacos parameter management to save fuse switch parameters. When the parameter value changes (open or close), the parameter change listener will listen to the change and reload the bean definition of the service provider, so as to achieve the purpose of real-time effectiveness of parameter changes.

[0067] like Figure 3 As shown, in one embodiment of the present invention, the service fusing method based on the Dubbo framework of the present invention includes step S301 and step S302.

[0068] Step S301, obtaining a modification instruction from a user to modify the fuse switch parameters of a target service;

[0069] Step S302: modify the fuse switch parameters corresponding to the target service in Nacos according to the modification instruction.

[0070] In one embodiment of the present invention, the user can also add and delete fuse switch parameters in Nacos.

[0071] From the above embodiments, the present invention supports manual configuration of the fuse conditions by defining Nacos parameters. At the same time, when the parameter value changes, it can be monitored in real time and handled accordingly through the Dubbo filter. Compared with the automatic fuse mechanism currently provided by Dubbo, the present invention adds a manual intervention mechanism, which is more flexible.

[0072] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
