一、引入相关jar
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-feign</artifactId>
</dependency>
二、在公共接口微服务模块创建公用接口并申明为@FeignClient
@FeignClient(value = "MICROSERVICECLOUD-DEPT")
public interface DeptClientService {
@RequestMapping(value = "/dept/get/{id}", method = RequestMethod.GET)
public Dept get(@PathVariable("id") long id);
@RequestMapping(value = "/dept/list", method = RequestMethod.GET)
public List<Dept> list();
@RequestMapping(value = "/dept/add", method = RequestMethod.POST)
public boolean add(Dept dept);
}
三、在引用公用接口的微服务模块中的启动类中添加Feign相关注解
@SpringBootApplication
@EnableEurekaClient//开启Eureka客户端
@EnableFeignClients(basePackages= {"com.zhq.springcloud"})
@ComponentScan("com.zhq.springcloud")
public class DeptConsumer80_Feign_App {
public static void main(String[] args) {
SpringApplication.run(DeptConsumer80_Feign_App.class, args);
}
}
四、引用所编写的接口
package com.zhq.springcloud.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.zhq.springcloud.entities.Dept;
import com.zhq.springcloud.service.DeptClientService;
@RestController
public class DeptController_Consumer {
@Autowired
private DeptClientService service = null;
@RequestMapping(value = "/consumer/dept/get/{id}")
public Dept get(@PathVariable("id") Long id) {
return this.service.get(id);
}
@RequestMapping(value = "/consumer/dept/list")
public List<Dept> list() {
return this.service.list();
}
@RequestMapping(value = "/consumer/dept/add")
public Object add(Dept dept) {
return this.service.add(dept);
}
}
