SpringBoot 整合 dubbo xml實現(xiàn)代碼示例

更新時間：2018年03月08日 09:41:54 作者：家住海邊喜歡浪

這篇文章主要介紹了SpringBoot 整合 dubbo xml實現(xiàn)代碼示例，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

昨天發(fā)布了注解方式，有人給我發(fā)了郵件希望能出一版本xml格式的，本來12點前能搞定的但是電腦稍微出了問題，導(dǎo)致idea 瘋狂奔潰，搞了很久廢話不多說了，有錯誤之處望大家指出發(fā)我郵箱.

用dubbo肯定是多模塊化了所以我們先創(chuàng)建一個聚合項目

這是項目結(jié)構(gòu)

Dubbo_demo 的pom 這個主要用來聚合業(yè)務(wù)模塊用不做任何業(yè)務(wù)處理

<?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.hzb</groupId>
  <artifactId>Dubbo_demo</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <!--我們這是多模塊開發(fā) 所以這邊要 變成 pom-->
  <packaging>pom</packaging>
  <!--系統(tǒng)模塊-->
  <modules>
    <module>hzbdubbo-consumer</module>
    <module>hzbdubbo-provider</module>
  </modules>
  <!--配置文件屬性-->
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.8</java.version>
  </properties>
</project>

然后按照上面的方法創(chuàng)建兩個項目一個是服務(wù)的提供者和服務(wù)的消費者

提供者和消費者不懂的話點擊這個連接了解一下http://dubbo.io/

服務(wù)提供者代碼片段：

生成基本項目按第一個圖片的去生成

代碼結(jié)構(gòu)：由于是demo不按規(guī)范結(jié)構(gòu)來看得懂就行

服務(wù)提供者pom ：

<?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"

注意pom中 parent 對應(yīng)的是什么和聚合pom進行關(guān)聯(lián)

dubbo.xml中配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://code.alibabatech.com/schema/dubbo
    http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    
  <!-- 配置可參考 http://dubbo.io/User+Guide-zh.htm -->
  <!-- 服務(wù)提供方應(yīng)用名，用于計算依賴關(guān)系 -->
  <dubbo:application name="dubbo-provider" owner="dubbo-provider" />
  
  <!-- 定義 zookeeper 注冊中心地址及協(xié)議 -->
  <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" client="zkclient" />
    
  <!-- 定義 Dubbo 協(xié)議名稱及使用的端口，dubbo 協(xié)議缺省端口為 20880，如果配置為 -1 或者沒有配置 port，則會分配一個沒有被占用的端口 -->
  <dubbo:protocol name="dubbo" port="-1" />
  
  <!-- 聲明需要暴露的服務(wù)接口 -->
  <dubbo:service interface="com.hzb.dubbo.provider.DemoService"
    ref="demoService" timeout="10000" />
    
  <!-- 和本地 bean 一樣實現(xiàn)服務(wù) -->
  <bean id="demoService" class="com.hzb.dubbo.provider.DemoServiceImpl" />
  
</beans>

這個想要了解配置的意思點擊這個連接：http://dubbo.io/books/dubbo-user-book-en/英文版https://help.github.com/categories/github-pages-basics/

服務(wù)提供者啟動類代碼：

package com.hzb.dubbo.provider;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
// 使用 dubbo.xml 配置
@ImportResource(value = {"classpath:dubbo.xml"})
public class DubboProviderApplication {

  public static void main(String[] args) {

    SpringApplication.run(DubboProviderApplication.class, args);
    System.out.println("服務(wù)提供者啟動成功");
  }
}

服務(wù) service接口代碼：

業(yè)務(wù)實現(xiàn)代碼：“

接下來就是服務(wù)消費者了：

項目結(jié)構(gòu)：

消費者pom 也是要注意pom中和上面有哪些不一樣和多了那個依賴
