Feign使用JAXRS注解

一 增加依赖

<!-- Feign对JAXRS的支持 -->
<dependency>
	  <groupId>io.github.openfeign</groupId>
	  <artifactId>feign-jaxrs</artifactId>
	  <version>9.5.0</version>
</dependency>
<!-- JAXRS -->
<dependency>
	  <groupId>javax.ws.rs</groupId>
	  <artifactId>jsr311-api</artifactId>
	  <version>1.1.1</version>
</dependency>

二 增加接口类

package org.crazyit.cloud.jaxrs;

import javax.ws.rs.GET;
import javax.ws.rs.Path;

public interface RsClient {

    @GET
    @Path("/hello")
    public String hello();
}

三 编写测试类

package org.crazyit.cloud.jaxrs;

import org.crazyit.cloud.HelloClient;

import feign.Feign;
import feign.jaxrs.JAXRSContract;

public class RsMain {

    public static void main(String[] args) {
        RsClient client = Feign.builder()
                .contract(new JAXRSContract())
                .target(RsClient.class,
                "http://localhost:8080");
        String result = client.hello();
        System.out.println(result);
    }

}

四 启动服务类

五 测试输出

Hello World
