　　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;
publicclass User implements Serializable {
private String userName;
private String password;
public String getUserName() {
return userName;
    }
publicvoid setUserName(String userName) {
this.userName = userName;
    }
public String getPassword() {
return password;
    }
publicvoid 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;
publicinterface 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
publicclass 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) {
returnnew 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
publicclass MySpringBootApplication {
publicstaticvoid 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
publicclass 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。
