Java FeignClient Interface exception solution for multiple identical service names

Little scum · Posted on 9/14/2021 6:05:15 PM

Spring Cloud uses OpenFeign for microservice communication, and the error is reported as follows when the same service name is different from the interface:

Description:

The bean 'itsvse. FeignClientSpecification' could not be registered. A bean with that name has already been defined and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

Cause analysis

The values of the multiple FeignClient interfaces defined are all xxxx-server, and the bean names of Springboot 2.2.x are named according to the value (i.e., name) of the @FeignClient, resulting in the bean being already defined.

Login is visible.

solution

Solution 1: According to the prompt of the error, add the following configuration:

Login is visible.

Solution 2, when defining FeignClient, define the contextId attribute at the same time, which will be included in the beanName rule, and there will be no exceptions where the bean has been defined.

Login is visible.

(End)

GET must not have a request body

feign must add @RequestParam when using okhttp3's Get method to request an interface.Controllers can be added without being added。

Examples include:
