service实现

package com.lovefly.pms.services.service;

import com.alibaba.dubbo.config.annotation.Service;
import com.lovefly.pms.interfaces.service.TestService;

@Service
public class TestServiceImpl implements TestService {
    @Override
    public String echo(String input) {

        return input + ": pong from service";
    }
}

consumer端

consumer实现

package com.lovefly.pms.portal.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.lovefly.pms.interfaces.service.TestService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/api/echo")
public class EchoController {

    @Reference
    private TestService echoService;

    @GetMapping("")
    public String echo(@RequestParam("input") String input){
        String pong = echoService.echo(input);
        return pong;
    }
}

application.properties

#server
server.port=8000

#dubbo
spring.dubbo.registry.group=pms
spring.dubbo.application.name=pms-portal
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.scan=com.lovefly.pms.portal
spring.dubbo.consumer.retries=0
spring.dubbo.consumer.timeout=30000
spring.dubbo.consumer.check=false

测试

启动zookeeper
使用curl或PostMan测试服务调用

curl -X GET http://localhost:8000/api/echo/?input=test
#输出：
test: pong from service

将目录添加到github项目中

进入工作目录
执行以下命令

$ mvn clean
$ git init
$ git add remote origin https://github.com/fuhongwei041/lovefly-pms.git
$ git branch --set-upstream-to=origin/master master
$ git pull origin master
$ # 编辑.gitignore文件
$ git add .
$ git commit -m "first commit"
