项目结构:

模块:test-client作为feignclient调用者。

模块:测试服务器作为feignclient接口的实现。

模块:test-common将所有feignclient放在一起。

常见测试:

package com.example.common.agent;
@FeignClient("hello")
public interface HelloAgent {
    @GetMapping("/hello")
    String hello(@RequestParam String msg);
}

测试服务器:(工作正常)

package com.example.server.controller;

@RestController
public class Hello implements HelloAgent {
    @Override
    public String hello(@RequestParam String msg) {
        System.out.println("get " + msg);
        return "Hi " + msg;
    }
}

测试客户端:

package com.example.client.controller;

@RestController
public class Hello {
    @Autowired
    private HelloAgent helloAgent;

    @GetMapping("/test")
    public String test() {
        System.out.println("go");
        String ret = helloAgent.hello("client");
        System.out.println("back " + ret);
        return ret;
    }
}

@EnableEurekaClient
@EnableFeignClients

无论如何,有没有将所有feignclient放在一起,以便我们可以优雅地管理它们?

还是只有冗余方式可以使用它们?

谢谢!

费恩不知道@ComponentScan

使用 @EnableFeignClients(basePackages = {"com.example.common.agent","com.example.client.controller"})
