1、服务生产者的pom文件中修改如下：

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

2、服务生产者配置修改application.yml：

server:
  port: 8001
dubbo:
  application:
    name: site-service-boot-provider
  registry:
    address: zookeeper://ubu:2181
  scan:
    base-packages: com.yas.serviceprovider
#  #指定某一种协议
#  protocol:
#    name: dubbo
#    port: 20882
  protocol:
    name: rest
    port: 8787

3、服务生产者提供rest服务--接受POST请求：

package com.yas.serviceprovider.protocol;

import com.yas.api.SiteService;
import org.apache.dubbo.config.annotation.Service;
import org.apache.dubbo.rpc.protocol.rest.support.ContentType;

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

@Service(version = "rest")
@Path("site")
public class RestImpl implements SiteService {
    @Override
    @POST
    @Path("name")
    @Produces({ContentType.APPLICATION_JSON_UTF_8,ContentType.TEXT_PLAIN_UTF_8})
    public String getName(String name) {
        System.out.println("/site/name接收到请求："+name);
        return "rest:" + name;
    }
}

4、测试POST请求：

使用postman请求地址：http://localhost:8787/site/name

请求方式为：post，请求参数为：body中的 name=zhangsan

由图可见，得到响应为：rest:name=zhangsan

---

5、服务生产者提供rest服务--接受GET请求：

package com.yas.serviceprovider.protocol;

import com.yas.api.SiteService;
import org.apache.dubbo.config.annotation.Service;
import org.apache.dubbo.rpc.protocol.rest.support.ContentType;

import javax.ws.rs.*;

@Service(version = "rest")
@Path("site")
public class RestImpl implements SiteService {
    @Override
    @GET
    @Path("name")
    @Produces({ContentType.APPLICATION_JSON_UTF_8,ContentType.TEXT_PLAIN_UTF_8})
    public String getName(@QueryParam("name") String name) {
        System.out.println("/site/name接收到请求："+name);
        return "rest:" + name;
    }
}

6、测试GET请求：

使用postman请求地址：http://localhost:8787/site/name?name=zhangsan

请求方式为：get，请求参数为：name=zhangsan

 由图可见，得到响应为：rest:zhangsan
