springboot整合dubbo\zookeeper做注册中心

　　springboot整合dubbo发布服务，zookeeper做注册中心。前期的安装zookeeper以及启动zookeeper集群就不说了。

　　dubbo-admin-2.5.4.war：dubbo服务管理项目，下载完后部署到tomcat即可查看(登录的用户名和密码默认都是root)。

pom文件引入dubbo以及zkcli包:

        <!-- 引入dubbo-spring-boot-starter以及zkclient依赖 -->

        <dependency>

            <groupId>com.alibaba.spring.boot</groupId>

            <artifactId>dubbo-spring-boot-starter</artifactId>

            <version>2.0.0</version>

        </dependency>

        <dependency>

            <groupId>com.101tec</groupId>

            <artifactId>zkclient</artifactId>

            <version>0.9</version>

        </dependency>

1.dubbo服务端(提供dubbo服务)

目录结构如下:

配置文件如下

application.properties

############################################################

#

# DUBBO相关配置

#

############################################################

#当前服务/应用名称

spring.dubbo.application.name=provider

#注册中心的协议和地址

#spring.dubbo.registry.address=127.0.0.1:2181

#spring.dubbo.registry.protocol=zookeeper

spring.dubbo.server=true

spring.dubbo.registry=zookeeper://127.0.0.1:2181

#通信规则(通信协议和接口)

spring.dubbo.protocol.name=dubbo

spring.dubbo.protocol.port=20880

User.java

package org.springboot.dubbo.bean;

import java.io.Serializable;

public class User implements Serializable {

    private String userName;

    private String password;

    public String getUserName() {

        return userName;

    }

    public void setUserName(String userName) {

        this.userName = userName;

    }

    public String getPassword() {

        return password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

    public User(String userName, String password) {

        super();

        this.userName = userName;

        this.password = password;

    }

}

UserService.java

package org.springboot.dubbo.service;

import java.util.List;

import org.springboot.dubbo.bean.User;

public interface UserService {

    List<User> getAllUsers();

    User getUserByUserName(String username);

}

UserServiceImpl.java (注解发布服务，注意@Service注解是dubbo提供的)

package org.springboot.dubbo.service;

import java.util.ArrayList;

import java.util.List;

import org.springboot.dubbo.bean.User;

import org.springframework.stereotype.Component;

import com.alibaba.dubbo.config.annotation.Service;

@Service(version = "1.0.0") // dubbo的service注解，不具备spring的@service注解的功能

@Component

public class UserServiceImpl implements UserService {

    public List<User> getAllUsers() {

        List<User> users = new ArrayList<User>();

        for (int i = 0; i < 20; i++) {

            User user = new User("usernnamei" + i, "password" + i);

            users.add(user);

        }

        return users;

    }

    public User getUserByUserName(String username) {

        return new User(username, username);

    }

}

应用启动类:

package org.springboot.dubbo;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;

@SpringBootApplication

@EnableDubboConfiguration

public class MySpringBootApplication {

    public static void main(String[] args) throws InterruptedException {

        // 入口运行类

        SpringApplication.run(MySpringBootApplication.class, args);

        Thread.sleep(50 * 1000);

    }

}

启动之后查看dubbo管理界面:

2.dubbo客户端(使用dubbo提供的服务)

目录结构:

application.properties

############################################################

#

# DUBBO相关配置

#

############################################################

#当前服务/应用名称

spring.dubbo.application.name=consumer

#注册中心的协议和地址

spring.dubbo.server=true

spring.dubbo.registry=zookeeper://127.0.0.1:2181

#通信规则(通信协议和接口)

spring.dubbo.protocol.name=dubbo

spring.dubbo.protocol.port=20880

spring.dubbo.scan=org.springboot.dubbo

UserController.java(通过@Reference消费服务)

package org.springboot.dubbo.controller;

import java.util.List;

import org.springboot.dubbo.bean.User;

import org.springboot.dubbo.service.UserService;

import org.springframework.stereotype.Controller;

import com.alibaba.dubbo.config.annotation.Reference;

@Controller

public class UserController {

    @Reference(version = "1.0.0")

    UserService userService;

    public List<User> getAllUsers() {

        return userService.getAllUsers();

    }

    public User getUserByUserName(String username) {

        return userService.getUserByUserName(username);

    }

}

结果:

[org.springboot.dubbo.bean.User@31741aad, org.springboot.dubbo.bean.User@3d836d38, org.springboot.dubbo.bean.User@7f779714, org.springboot.dubbo.bean.User@45fe36d, org.springboot.dubbo.bean.User@334c0b59, org.springboot.dubbo.bean.User@457d1a5e, org.springboot.dubbo.bean.User@184e34f6, org.springboot.dubbo.bean.User@36770ef1, org.springboot.dubbo.bean.User@42760c26, org.springboot.dubbo.bean.User@5417b4e0, org.springboot.dubbo.bean.User@60640941, org.springboot.dubbo.bean.User@479bbbd7, org.springboot.dubbo.bean.User@414944fb, org.springboot.dubbo.bean.User@314fdc39, org.springboot.dubbo.bean.User@72033b79, org.springboot.dubbo.bean.User@3235bf69, org.springboot.dubbo.bean.User@66a9a03f, org.springboot.dubbo.bean.User@a57bcc1, org.springboot.dubbo.bean.User@6292835, org.springboot.dubbo.bean.User@780eb2bb]
org.springboot.dubbo.bean.User@605dfc60

管理界面查看如下:

　　至此基本完成了简单的dubbo环境搭建。
