## 简介 ##

本文介绍feign对一个服务定义多个FeignClient时的报错：The bean 'xxx' could not be registered. A bean with that name has already been defined and overriding is disabled.

## 问题复现 ##

@FeignClient("user")
    public interface TestLongFeignService {
        @PostMapping("/user/long")
        public ResultWrapper testLong(String param1);
    }

@FeignClient("user")
    public interface UserFeignService {
        @GetMapping("/user/{id}")
        public User getUser(@PathVariable("id") Long id);
    }

错误日志：

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

## 解决方案 ##

### 方案1：使用contextId属性 ###

@FeignClient(value = "user", contextId = "user1")
    public interface TestLongFeignService {
        @PostMapping("/user/long")
        public ResultWrapper testLong(String param1);
    }

@FeignClient(value = "user", contextId = "user2")
    public interface UserFeignService {
        @GetMapping("/user/{id}")
        public User getUser(@PathVariable("id") Long id);
    }

### 方案2：方法都放到同一个类里边 ###

@FeignClient("user")
    public interface UserFeignService {
        @GetMapping("/user/{id}")
        public User getUser(@PathVariable("id") Long id);
    
        @PostMapping("/user/long")
        public ResultWrapper testLong(String param1);
    }
