spring boot dubbo 简单例子

spring boot dubbo demo

首先spring boot简化了spring的配置，方便使用，写一下spring boot dubbo 的整合的文章。

先下载zookeeper,然后解压就行。在这个目录，双击zkServer.cmd就行。linux的用命令行./zkServer.sh start

上代码前，介绍一下dubbo
DUBBO是一个分布式服务框架，致力于提供高性能和透明化的RPC远程服务调用方案。可以实现系统之间的调用，可以进行
下面开始上代码，项目结构如图：

city.java 实体

package org.spring.springboot.domain;import java.io.Serializable;/** * 城市实体类 * * Created by bysocket on 07/02/2017. */public class City implements Serializable {    private static final long serialVersionUID = -1L;    /**     * 城市编号     */    private Long id;    /**     * 省份编号     */    private Long provinceId;    /**     * 城市名称     */    private String cityName;    /**     * 描述     */    private String description;    public Long getId() {        return id;    }    public void setId(Long id) {        this.id = id;    }    public Long getProvinceId() {        return provinceId;    }    public void setProvinceId(Long provinceId) {        this.provinceId = provinceId;    }    public String getCityName() {        return cityName;    }    public void setCityName(String cityName) {        this.cityName = cityName;    }    public String getDescription() {        return description;    }    public void setDescription(String description) {        this.description = description;    }    @Override    public String toString() {        return "City{" +                "id=" + id +                ", provinceId=" + provinceId +                ", cityName='" + cityName + '\'' +                ", description='" + description + '\'' +                '}';    }}

dubbo 消费者

package org.spring.springboot.dubbo;import com.alibaba.dubbo.config.annotation.Reference;import org.spring.springboot.domain.City;import org.springframework.stereotype.Component;/** * 城市 Dubbo 服务消费者 * * Created by bysocket on 28/02/2017. */@Componentpublic class CityDubboConsumerService {    @Reference(version = "1.0.0")    private CityDubboService cityDubboService;    public void printCity() {        String cityName="温岭";        City city = cityDubboService.findCityByName(cityName);        System.out.println(city.toString());    }}

dubbo server 接口

package org.spring.springboot.dubbo;import org.spring.springboot.domain.City;/** * 城市业务 Dubbo 服务层 * * Created by bysocket on 28/02/2017. */public interface CityDubboService {    /**     * 根据城市名称，查询城市信息     * @param cityName     */    City findCityByName(String cityName);}

spring boot 启动

package org.spring.springboot;import org.spring.springboot.dubbo.CityDubboConsumerService;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ConfigurableApplicationContext;/** * Spring Boot 应用启动类 * * Created by bysocket on 16/4/26. */// Spring Boot 应用的标识@SpringBootApplicationpublic class ClientApplication {    public static void main(String[] args) {        // 程序启动入口        // 启动嵌入式的 Tomcat 并初始化 Spring 环境及其各 Spring 组件        ConfigurableApplicationContext run = SpringApplication.run(ClientApplication.class, args);        CityDubboConsumerService cityService = run.getBean(CityDubboConsumerService.class);        cityService.printCity();    }}

application.properties

## 避免和 server 工程端口冲突server.port=8081## Dubbo 服务消费者配置spring.dubbo.application.name=consumerspring.dubbo.registry.address=zookeeper://127.0.0.1:2181spring.dubbo.scan=org.spring.springboot.dubbo

dubbo server :

package org.spring.springboot.dubbo.impl;import com.alibaba.dubbo.config.annotation.Service;import org.spring.springboot.domain.City;import org.spring.springboot.dubbo.CityDubboService;import org.springframework.beans.factory.annotation.Autowired;/** * 城市业务 Dubbo 服务层实现层 * * Created by bysocket on 28/02/2017. */// 注册为 Dubbo 服务@Service(version = "1.0.0")public class CityDubboServiceImpl implements CityDubboService {    public City findCityByName(String cityName) {        return new City(1L,2L,"温岭","是我的故乡");    }}

server配置

## Dubbo 服务提供者配置spring.dubbo.application.name=providerspring.dubbo.registry.address=zookeeper://127.0.0.1:2181spring.dubbo.protocol.name=dubbospring.dubbo.protocol.port=20880spring.dubbo.scan=org.spring.springboot.dubbo

先启动server,然后启动client端，可以看到以下信息。
