dubbo-springboot
一、服务提供者boot-user-service-provider
服务提供者boot-user-service-provider代码结构如下：
1、服务提供者boot-user-service-provider引入spring-boot-starter以及dubbo和curator的依赖
注意starter版本适配：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.boot</groupId>
<artifactId>dubbo-spring-boot-starter</artifactId>
<version>0.2.0</version>
</dependency>
引入spring-boot-starter以及dubbo和curator的依赖后的pom.xml文件内容如下：
<?xml version="1.0" encoding="UTF-8"?>

2、配置文件application.properties
#服务名，不能跟别的dubbo服务提供者重复 dubbo.application.name=boot-user-service-provider #指定注册中心的地址和端口号 dubbo.registry.address=127.0.0.1:2181 #指定注册中心协议 dubbo.registry.protocol=zookeeper #指定通信规则（通信协议&通信端口） dubbo.protocol.name=dubbo dubbo.protocol.port=20880 #连接监控中心 dubbo.monitor.protocol=registry
3、UserService接口实现UserServiceImpl
package com.lina02.gmall.service.impl;
import com.lina02.gmall.bean.UserAddress;
import com.lina02.gmall.service.UserService;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import java.util.Arrays;
import java.util.List;
@com.alibaba.dubbo.config.annotation.Service //暴露服务
//@Service
@Component
public class UserServiceImpl implements UserService {
@Override
public List<UserAddress> getUserAddressList(String userId) {
System.out.println("UserServiceImpl..3.....");
UserAddress address1 = new UserAddress(1, "北京市昌平区宏福科技园综合楼3层", "1", "李老师", "010-56253825", "Y");
UserAddress address2 = new UserAddress(2, "深圳市宝安区西部硅谷大厦B座3层（深圳分校）", "1", "王老师", "010-56253825", "N");
return Arrays.asList(address1,address2);
}
}
4、主程序
package com.lina02.gmall;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@EnableDubbo //开启dubbo注解
@SpringBootApplication
public class BootUserServiceProviderApplication {
public static void main(String[] args) {
SpringApplication.run(BootUserServiceProviderApplication.class, args);
}
}
二、服务消费者boot-order-service-consumer
服务消费者boot-order-service-consumer代码结构如下：
1、pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2、配置文件application.propertise
#配置服务端口 server.port=8081 #服务名，不能跟别的dubbo服务提供者重复 dubbo.application.name=boot-order-service-consumer #指定注册中心协议、地址、端口号 dubbo.registry.address=zookeeper://127.0.0.1:2181 #连接监控中心 dubbo.monitor.protocol=registry
3、OrderService接口实现OrderServiceImpl
package com.lina02.gmall.service.impl;
import com.alibaba.dubbo.config.annotation.Reference;
import com.lina02.gmall.bean.UserAddress;
import com.lina02.gmall.service.OrderService;
import com.lina02.gmall.service.UserService;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* 1、将服务提供者注册到注册中心（暴露服务）
* 1）、导入dubbo依赖（2.6.2）\操作zookeeper的客户端(curator)
* 2）、配置服务提供者
*
* 2、让服务消费者去注册中心订阅服务提供者的服务地址
*/
@Service
public class OrderServiceImpl implements OrderService {
//@Autowired
@Reference //订阅的服务
UserService userService;
@Override
public List<UserAddress> initOrder(String userId) {
System.out.println("用户id："+userId);
//1、查询用户的收货地址
List<UserAddress> addressList = userService.getUserAddressList(userId);
return addressList;
}
}
4、OrderController
package com.lina02.gmall.controller;
import com.lina02.gmall.bean.UserAddress;
import com.lina02.gmall.service.OrderService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.List;
@Controller
public class OrderController {
@Autowired
OrderService orderService;
@ResponseBody
@RequestMapping("/initOrder")
public List<UserAddress> initOrder(@RequestParam("uid") String userId){
return orderService.initOrder(userId);
}
}
5、主程序
package com.lina02.gmall;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@EnableDubbo //开启dubbo注解
@SpringBootApplication
public class BootOrderServiceConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(BootOrderServiceConsumerApplication.class, args);
}
}
