创建3个项目
新建一个maven项目，这个项目只有接口(或实体类)
dubbo-service和dubbo-web这两个依赖于dubbo-api
<groupId>com.zhang</groupId> <artifactId>dubbo-api</artifactId> <version>1.0</version>
package com.zhang.service; public interface UserService { public String login(String username); }
dubbo服务provider
<groupId>com.zhang</groupId> <artifactId>dubbo-service</artifactId> <version>1.0</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.3.RELEASE</version> </parent>
Maven依赖
<dependencies> <dependency> <groupId>io.dubbo.springboot</groupId> <artifactId>spring-boot-starter-dubbo</artifactId> <version>1.0.0</version> </dependency> <dependency> <groupId>com.zhang</groupId> <artifactId>dubbo-api</artifactId> <version>1.0</version> </dependency> </dependencies>
service实现类，用@Service注解
package com.zhang.service; import com.alibaba.dubbo.config.annotation.Service; @Service(version="1.0.0") public class UserServiceImpl implements UserService{ @Override public String login(String username) { System.out.println("username:" + username); return "my name is " + username; } }
application.properties配置，spring.dubbo.scan=服务的package
spring.dubbo.application.name=provider
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.scan=com.zhang.service
dubbo服务consumer
<groupId>com.zhang</groupId> <artifactId>dubbo-web</artifactId> <version>1.0</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.3.RELEASE</version> </parent>
maven依赖
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>com.zhang</groupId> <artifactId>dubbo-api</artifactId> <version>1.0</version> </dependency> <dependency> <groupId>io.dubbo.springboot</groupId> <artifactId>spring-boot-starter-dubbo</artifactId> <version>1.0.0</version> </dependency> </dependencies>
新建一个Controller类
package com.zhang.service; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import com.alibaba.dubbo.config.annotation.Reference; @Controller public class Person { @Reference(version = "1.0.0") private UserService userService; @RequestMapping("/login") @ResponseBody public String run() { return userService.login("abcd"); } }
springboot入口类
package com.zhang.service; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class App { public static void main(String[] args) { SpringApplication.run(App.class, args); } }
application.properties
spring.dubbo.application.name=consumer spring.dubbo.registry.address=zookeeper://127.0.0.1:2181 spring.dubbo.scan=com.zhang.service
1、先自动zookeeper
2、启动dubbo-service
3、启动dubbo-web
测试方式，直接在浏览器地址里输入http://localhost:8080/login
