This article mainly shows you "how to solve the version problem of Feignclient call in Springboot", which is easy to understand and well-organized. I hope it can help you solve your doubts. Let the editor lead you to study and learn this article "how to solve the version problem of Feignclient call in Springboot".

There are three Springboot projects, namely jpmc-adapter, gsdic-api and twpre-api. Gsdic-api and twpre-api are public services that provide the API of Restful and are called through feign client.

The big background is

Jpmc-adapter now needs to invoke two other public services.

Springboot version:

Jpmc-adapter 1.5.9

Gsdic-api 1.5.9

Twpre-api 2.0.5

You can see that the Springboot versions of jpmc-adaper and gsdic-api are the same. If jpmc-adaper simply calls gsdic-api through feign client, everything is OK!

The situation now is that jpmc-adaper needs to call both gsdic-api and twpre-api, and then reports an error when starting the project

The error is as follows

This is a problem caused by inconsistent versions of Springboot.

Let's first look at how the other two services are invoked in jpmc-adaper.

It is roughly as follows:

1. Introduce jar packages for two other public services into build.gradle.

2. Unified management depends on the version number in gradle.properties, as follows:

3. Start the configuration of the public service introduced into the class:

4. The call in the test class is as follows:

The FeignClient of twpre-api is from org.springframework.cloud.openfeign.FeignClient; as follows:

The FeignClient of gsdic-api comes from org.springframework.cloud.netflix.feign.FeignClient, as follows:

The solution is as follows

You can change the version of all services to be consistent, so that you can avoid such problems. However, changing versions may cause a lot of problems, which can be solved in the following ways:

Because the versions of jpmc-adapter and gsdic-api are the same, we override the FeignClient of twpre-api in the caller, that is, jpmc-adapter.

Package com.geoswift.jpmc.api; import org.springframework.cloud.netflix.feign.FeignClient; import com.geoswift.twpre.fapi.TwpreRestAPI; @ FeignClient (name= "twpre", path= "/ api/twpre/v1") public interface MyTwpreRestAPI extends TwpreRestAPI {}

Then use our rewritten client during the test, as follows:
