springboot_整合dubbo

 

一、目录结构

顾名思义，boot-meet-service-consumer是作为消费者，boot-user-service-provider作为服务提供者，meeting-interface用于存放接口和bean。

二、meeting-interface

 这里Meeting

    private String id;

    private String pcode;

    private  String title;

    private String content;

    private String uid;

    private User user;

User

    private String id;
    private String name;
    private String phonenum;

MeetingPubService:

package com.rong.service;

import com.rong.bean.Meeting;

public interface MeetingPubService {
    /**
     * 根据会议编号查询详细信息
     */
    Meeting selectMeetingByPcode(String pcode);
}

UserService:

public interface UserService {

    User selectUserById(String id);
}

三、Provider和Consumer都需要的依赖

        <!--引入meeting-interface的依赖  -->
         <dependency>
            <groupId>com.rong</groupId>
            <artifactId>meeting-interface</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

        <!--引入dubbo  -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.6.2</version>
        </dependency>

        <!-- 注册中心使用的是zookeeper,引入操作zookeeper的客户端 -->
        <dependency>
            <groupId>org.apache.curator</groupId>
            <artifactId>curator-framework</artifactId>
            <version>2.12.0</version>
        </dependency>
        <!-- Dubbo Spring Boot Starter -->
        <dependency>
            <groupId>com.alibaba.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>0.2.1.RELEASE</version>
        </dependency>

四、provider

目录结构

UserServiceImpl

package com.rong.boot.service.impl;

import com.rong.bean.User;
import com.rong.service.UserService;
import org.springframework.stereotype.Component;

@com.alibaba.dubbo.config.annotation.Service//暴露服务
@Component
public class UserServiceImpl implements UserService {

    /**
     * 根据用户名查找用户信息
     * @param id
     * @return
     */
    public User selectUserById(String id) {

        User user = new User(id,"jack","1326364386");
        return user;
    }
}

BootUserServiceProviderApplication

package com.rong.boot;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableDubbo//开启基于注解的dubbo功能
@SpringBootApplication
public class BootUserServiceProviderApplication {

    public static void main(String[] args) {
        SpringApplication.run(BootUserServiceProviderApplication.class, args);
    }

}

provider的application.properties

dubbo.application.name=boot-user-service-provider
dubbo.registry.address=127.0.0.1:2181
dubbo.registry.protocol=zookeeper

dubbo.protocol.name=dubbo
dubbo.protocol.port=20880

dubbo.monitor.protocol=registry

五、Consumer

目录结构

MeetingController

package com.rong.boot.controller;

import com.rong.bean.Meeting;
import com.rong.service.MeetingPubService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.Mapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MeetingController {

    @Autowired
    MeetingPubService meetingPubService;


    @GetMapping("/meeting")
    public String getMeeting(){
        Meeting meeting = meetingPubService.selectMeetingByPcode("123");
        System.out.println(meeting);

        return "ok";
    }
}

MeetingPubServiceImpl

package com.rong.boot.service;

import com.alibaba.dubbo.config.annotation.Reference;
import com.rong.bean.Meeting;
import com.rong.bean.User;
import com.rong.service.MeetingPubService;
import com.rong.service.UserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;


@Service
public class MeetingPubServiceImpl implements MeetingPubService {

    @Reference
    UserService userService;

    public Meeting selectMeetingByPcode(String pcode) {
        System.out.println("传进来的pcode"+pcode);
        Meeting meeting = new Meeting();
        meeting.setId("1001");
        meeting.setPcode(pcode);
        meeting.setTitle("学习dubbo");
        meeting.setContent("Dubbo真好玩");
        meeting.setUid("123");
        User user = userService.selectUserById(meeting.getUid());
        meeting.setUser(user);
        return meeting;
    }
}

application.properties

server.port=8082

dubbo.application.name=boot-meeting-service-consumer
dubbo.registry.address=127.0.0.1:2181
dubbo.registry.protocol=zookeeper
dubbo.monitor.protocol=registry

六、测试

打开浏览器，在地址栏中输入localhost:8082/meeting出现下图所示就成功了
