A specific embodiment is given below to illustrate a specific application of the method of the present invention, and in this embodiment, as shown in fig. 2, the following steps may be included:
step 201: starting a Spring project:
firstly, running a project using a Spring framework, scanning a Dubbo XML configuration file and related codes involved in configuration during the starting process of the Spring framework, and loading and instantiating a Dubbo Reference object from the configuration file.
The BeanPostprocessor class is called up in the Spring starting process, and the following subsequent flow is executed;
step 202: obtaining a Dubbo Reference object:
the source data processed in the step is a Dubbo XML configuration file and a Dubbo Reference object loaded in Spring, the Dubbo XML file is analyzed to obtain related information such as the id of Dubbo, and the corresponding Dubbo Reference object to be replaced is taken out from a Spring container through the id;
step 203: generating a Feign object:

step 205: and after the replacement, continuing to finish the subsequent processing of Spring starting, and after the starting is finished, converting the Dubbo protocol interface call into a Feign interface call of an Http protocol.
In this embodiment, the basic flow of the embodiment of the present invention is to obtain a Dubbo Reference object, generate a Feign object according to the Dubbo configuration file information, and finally replace the Dubbo Reference object with the Feign object. Wherein the core step is the process of generating Feign objects. The embodiment of the invention can complete the conversion of the protocol only by modifying the code and adding a configuration file.
Of course, it is understood that other variations of the above detailed flow can be made, and all such variations are intended to fall within the scope of the present invention.
In the embodiment of the invention, after the operation of the Dubbo project is triggered, the configuration information of the Dubbo interface is obtained according to a plurality of Dubbo XML configuration files; scanning a plurality of Dubbo XML configuration files based on instantiation processing to obtain a plurality of Dubbo Reference objects; determining a Dubbo Reference object to be replaced from the plurality of Dubbo Reference objects according to the configuration information of the Dubbo interface and the Spring container context of the Dubbo engineering; the Dubbo Reference object is used to consume a bean of the Dubbo protocol type; for each Dubbo Reference object to be replaced, converting the Dubbo Reference object to be replaced into a corresponding Feign object according to the configuration information of the Dubbo interface; the Feign object is used for consuming an Http interface; the generated license object is used for correspondingly replacing the Dubbo Reference object to be replaced, compared with the technical scheme that the Dubbo protocol interface is translated into the Http protocol interface through manual modification in the prior art, the conversion of the RPC protocol of a consumer side can be completed in the running Springboot engineering by directly converting the Dubbo Reference object into the corresponding license object, the problem of high development cost caused by the fact that codes need to be developed manually to realize the conversion of the RPC protocol in the prior art is solved, a large amount of codes are not required to be developed, and manpower and material resources are saved; meanwhile, the problem that in the prior art, a person with code development capability can realize RPC protocol conversion to cause difficulty in implementation is solved, the method is simple to use, and does not invade the original code, so that the conversion convenience of the Dubbo protocol is improved, and the conversion efficiency of the Dubbo protocol is improved.
As mentioned above, the current RPC protocol conversion scheme has the following two disadvantages:
1. development and modification costs are high:
the existing scheme needs to develop new codes, all the existing codes are newly developed and replaced by one set, and if the number of interfaces is large, the repeated operation can occupy a large amount of labor cost.
2. The requirement on developers is high:
the current scheme has certain requirements on developers and needs to have the capability of developing the Feign interface call of the Http protocol. A person just touching the item code would have difficulty implementing the solution.
Aiming at the first defect, the embodiment of the invention avoids the development of a large number of codes, and completes the conversion of RPC protocol call only by modifying limited codes and configuration files, so the development cost is low and controllable, and the cost is not uncontrollable due to the number of interface codes;
aiming at the second defect, the embodiment of the invention does not need developers to comprehensively know project codes and master the configuration method of the Feign interface of the Http protocol, only needs to be modified by the configuration of a section of basically fixed codes and a section of fixed contents, and can be configured according to the invention requirement, thereby having lower requirements on personnel and being easy to use.
To sum up, the embodiment of the present invention can convert the Dubbo protocol interface call into the Http protocol interface call for the Springboot project, and dynamically generate the compiled Http protocol interface call Feign object, which is in the form of a class file, by using the bytecode enhancement technology during the running period of the Springboot project to convert the protocol. And loading the generated class file in the running process of the Springboot project, replacing the previous Dubbo interface call, namely converting the consumer into an Http interface call, and requiring no modification on the original service code.
The embodiment of the invention also provides a device for converting the Dubbo protocol in the operating period, which is as described in the following embodiment. Because the principle of the device for solving the problems is similar to the Dubbo protocol conversion method in the operation period, the implementation of the device can refer to the implementation of the Dubbo protocol conversion method in the operation period, and repeated parts are not described again.
