通过三个工程演示整合过程

工程一：API工程：服务端与客户端共同需要引入的工程

pom:无特殊依赖，下边内容供服务端与客户端引用此工程使用


    
     com.boot.dubbo.demo
      
    
     dubbo-api
      
    
     1.0-SNAPSHOT

实体类:

package com.boot.dubbo.demo.domain;import java.io.Serializable;/** * 用户信息类 */public class UserInfo implements Serializable {    private String account;    private String password;    public String getAccount() {        return account;    }    public void setAccount(String account) {        this.account = account;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }}

API:

package com.boot.dubbo.demo.api;import com.boot.dubbo.demo.domain.UserInfo;public interface UserService {    // 定义用户登录的api    UserInfo login(UserInfo user);}

工程二：生产者工程：服务端

pom


            
                
     
      com.boot.dubbo.demo
                 
     
      boot-dubbo-api
                 
     
      1.0-SNAPSHOT

dubbo必须依赖项：（使用zk）


        
     
      com.alibaba.spring.boot
         
     
      dubbo-spring-boot-starter
         
     
      2.0.0
     
    
        
     
      com.101tec
         
     
      zkclient
         
     
      0.10
     
    
        
     
      org.apache.zookeeper
         
     
      zookeeper
         
     
      3.4.10
         
             
                  
       
        org.slf4j
                   
       
        slf4j-log4j12
               
              
                  
       
        log4j
                   
       
        log4j

application.yml：配置dubbo配置项

spring:  dubbo:    application:      name: dubbo-provider    protocol:      name: dubbo      port: 20880    registry:      address: zookeeper://192.168.3.101:2181

package com.boot.dubbo.demo.dubboprovider.service;import com.alibaba.dubbo.config.annotation.Service;import com.boot.dubbo.demo.api.UserService;import com.boot.dubbo.demo.domain.UserInfo;import org.springframework.stereotype.Component;@Component@Service(interfaceClass = UserService.class) //注意是dubbo的注解，向外暴露接口public class UserServiceImpl implements UserService {    public UserInfo login(UserInfo user) {        UserInfo reUser = new UserInfo();        reUser.setAccount("登录的账号为:"+user.getAccount());        reUser.setPassword("登录的密码为:"+user.getPassword());        return reUser;    }}

package com.boot.dubbo.demo.dubboprovider;import com.alibaba.dubbo.spring.boot.annotation.EnableDubbo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication@EnableDubbo // 启用dubbopublic class DubboProviderApplication {    public static void main(String[] args) {        SpringApplication.run(DubboProviderApplication.class, args);    }}

工程三：消费者工程：客户端

pom依赖与工程二相同

application.yml配置：

spring:  dubbo:    application:      name: dubbo-provider    protocol:      name: dubbo      port: 20880    registry:      address: zookeeper://192.168.3.101:2181server:  port: 8081

Controller

package com.boot.dubbo.demo.dubboconsumer.controller;import com.alibaba.dubbo.config.annotation.Reference;import com.boot.dubbo.demo.api.UserService;import com.boot.dubbo.demo.domain.UserInfo;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class UserController {    @Reference // 引用dubbo服务器提供服务器接口    private UserService userService;    @GetMapping("/login")    public UserInfo login(UserInfo userInfo) {        return userService.login(userInfo);    }}

package com.boot.dubbo.demo.dubboconsumer;import com.alibaba.dubbo.spring.boot.annotation.EnableDubbo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication@EnableDubbopublic class DubboConsumerApplication {    public static void main(String[] args) {        SpringApplication.run(DubboConsumerApplication.class, args);    }}

这样客户端就可以通过Dubbo调用服务端提供的方法了
