[开发工具]@RestController实现@FeignClient接口时出现的问题

作者:token annotation punctuation

fegin 接口

package com.xxx.api;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created with IntelliJ IDEA.
 *
 * @author: zhouzhaoxu
 */
@FeignClient(value = "Test", contextId = "Test-XxxServiceI")
@RequestMapping(path = "/Test")
public interface XxxServiceI {

    @PostMapping(path = "/add/v1")
    String add(
        @Parameter(name = "参数") @RequestBody Object object);


}

controller 接口

package com.xxx.controller;

import lombok.RequiredArgsConstructor;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created with IntelliJ IDEA.
 *
 * @author: zhouzhaoxu
 */
@RestController("XxxController")
@RequiredArgsConstructor
public class XxxController implements XxxfServiceI {

    private final XxxService xxxService;

    @Override
    public String createStoreCommodityGroup(Object object) {
        String id = xxxService.add(object);
        return id;
    }
}

启动类

@EnableFeignClients(basePackages = {"com.xxx"})
@SpringBootApplication
public class Application {
    /**
     *
     *
     * @param args
     */
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

异常信息

Caused by: java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'com.aliyun.bizworks.operation.client.commodity.api.OperationCommodityServiceI' method 
com.aliyun.bizworks.operation.client.commodity.api.OperationCommodityServiceI#createCommodity(OperationCommodityCreateDTO)
to {POST /Operation/commodity/createCommodity/v1}: There is already 'OperationCommodityServiceController' bean method

异常原因

在启动类上的 @EnableFeignClients(basePackages = {"com.xxx"})注解，扫描到了controller层和api层，因为controller层实现了api接口，所以会扫描到两次相同的路径，
解决办法，扫描@EnableFeignClients的包路径详细到fegin接口的包下

@EnableFeignClients(basePackages = {"com.xxx.api"})
@SpringBootApplication
public class Application {
    /**
     *
     *
     * @param args
     */
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
