SpringBoot整合dubbo SpringBoot 整合 dubbo xml实现代码示例

家住海边喜欢浪 人气:0
想了解SpringBoot 整合 dubbo xml实现代码示例的相关内容吗,家住海边喜欢浪在本文为您仔细讲解SpringBoot整合dubbo的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:SpringBoot整合dubbo,dubbo,xml,springboot整合dubbox,下面大家一起来学习吧。

昨天发布了注解方式,有人给我发了邮件希望能出一版本xml格式的,本来12点前能搞定的但是电脑稍微出了问题,导致idea 疯狂奔溃,搞了很久废话不多说了,有错误之处望大家指出发我邮箱.

用dubbo肯定是多模块化了 所以我们先创建一个聚合项目


这是项目结构

Dubbo_demo 的pom 这个主要用来聚合业务模块用不做任何业务处理

<?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>
  <!--我们这是多模块开发 所以这边要 变成 pom-->
  <packaging>pom</packaging>
  <!--系统模块-->
  <modules>
    <module>hzbdubbo-consumer</module>
    <module>hzbdubbo-provider</module>
  </modules>
  <!--配置文件属性-->
  <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创建两个项目一个是 服务的提供者 和服务的消费者

提供者和消费者不懂的话点击这个连接了解一下http://dubbo.io/

服务提供者代码片段:

生成基本项目按第一个图片的去生成

代码结构: 由于是demo不按规范结构来看得懂就行

服务提供者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"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>

注意pom中 parent 对应的是什么和聚合pom进行关联

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">
    
  <!-- 配置可参考 http://dubbo.io/User+Guide-zh.htm -->
  <!-- 服务提供方应用名,用于计算依赖关系 -->
  <dubbo:application name="dubbo-provider" owner="dubbo-provider" />
  
  <!-- 定义 zookeeper 注册中心地址及协议 -->
  <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" client="zkclient" />
    
  <!-- 定义 Dubbo 协议名称及使用的端口,dubbo 协议缺省端口为 20880,如果配置为 -1 或者没有配置 port,则会分配一个没有被占用的端口 -->
  <dubbo:protocol name="dubbo" port="-1" />
  
  <!-- 声明需要暴露的服务接口 -->
  <dubbo:service interface="com.hzb.dubbo.provider.DemoService"
    ref="demoService" timeout="10000" />
    
  <!-- 和本地 bean 一样实现服务 -->
  <bean id="demoService" class="com.hzb.dubbo.provider.DemoServiceImpl" />
  
</beans>

这个想要了解配置的意思点击这个连接:http://dubbo.io/books/dubbo-user-book-en/英文版https://help.github.com/categories/github-pages-basics/

服务提供者启动类代码:

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("服务提供者启动成功");
  }
}

服务 service接口代码:


业务实现代码:“

接下来就是服务消费者了:

项目结构:


消费者pom 也是要注意pom中和上面有哪些不一样 和 多了那个依赖

dubbo.xml配置:


启动类:


测试调用服务Controller

接下来就是先把服务提供者启动起来 然后在启动消费者
