2 privider 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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.czxy</groupId> <artifactId>dubboprivide</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>dubboprivide</name> <description>Demo project for Spring Boot</description> <parent> <artifactId>dubbodemo</artifactId> <groupId>com.czxy</groupId> <version>0.0.1-SNAPSHOT</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>com.czxy</groupId> <artifactId>dubboapi</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2.1 properties配置檔案的編寫
server.port = 9090 spring.application.name = dubbo-provider #指定當前服務/應用的名字（同樣的服務名字相同，不要和別的服務同名） dubbo.application.name = dubbo-provider #用dubbo協議在20880埠暴露服務 dubbo.protocol.name = dubbo dubbo.protocol.port = 20880 #指定註冊中心的位置 dubbo.registry.address = zookeeper://localhost:2181 #統一設定服務提供方的規則 dubbo.provider.timeout = 1000
2.2 實現介面的類
package com.czxy.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
import com.czxy.api.DemoService;
/**
* @author zhenglong
* @Description: DemoService的實現類
* @Date 2018/11/20 21:22
* com.alibaba.dubbo.config.annotation.Service 不是spring的service
*/
@Service
public class DemoServiceImpl implements DemoService {
@Override
public String helloWorld(String name) {
return null;
}
}
2.3 privider啟動器
package com.czxy;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @author zhenglong
* @Date 2018/11/20 21:22
* 開啟dubbo 相當於@DubboComponentScan與@EnableDubboConfig結合
*/
@EnableDubbo
@SpringBootApplication
public class DubboprivideApplication {
public static void main(String[] args) {
SpringApplication.run(DubboprivideApplication.class, args);
}
}
3 公共的介面類
package com.czxy.api;
/**
* @author zhenglong
* @Description: 服務demo介面類
* @Date 2018/11/27 21:22
*/
public interface DemoService {
/**
* @param name
* @return
*/
String helloWorld(String name);
}
3 customer 消費端的pom.xml

3.1 customer 消費端的controller
package com.czxy.conroller;
import com.alibaba.dubbo.config.annotation.Reference;
import com.czxy.api.DemoService;
import com.czxy.api.UserService;
import com.czxy.api.domain.User;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @author zhenglong
* @Description: 消費端controller
* @Date 2018/11/20 21:22
*/
@RestController
public class DemoConsumerController {
/**
* @Reference來注入服務端爆露的介面
*/
@Reference
private DemoService demoService;
/**
* @Description:demoService 介面呼叫的方法
*/
@RequestMapping("/HelloWorld")
public String sayHello( String name) {
return demoService.helloWorld(name);
}
}
3.2 customer消費端的啟動器
package com.czxy;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @author zhenglong
* @Date 2018/11/20 21:22
* 開啟dubbo 相當於@DubboComponentScan與@EnableDubboConfig結合
*/
@SpringBootApplication
@EnableDubbo
public class DubbocustomerApplication {
public static void main(String[] args) {
SpringApplication.run(DubbocustomerApplication.class, args);
}
}
