① 在 project_name-feign-api定义远程接口 

板块名+路径 

package com....;

import ..

@FeignClient("板块名")
public interface IWemediaClient {

    @GetMapping("路径")
    public ResponseResult getChannels();
}

② 在  被调用的（板块名） 端提供接口

controller层

package ..
import ..

@RestController
public class WemediaClient implements IWemediaClient {

    @Autowired
    private WmChannelService wmChannelService;

    @GetMapping("路径")
    @Override
    public ResponseResult getChannels() {
        return wmChannelService.findAll();
    }
}
