  • Windows下dubbo环境搭建及初步使用

    一、dubbo简介

      Dubbo是阿里巴巴公司开源的一个高性能优秀的服务框架,使得应用可通过高性能的 RPC 实现服务的输出和输入功能,可以和Spring框架无缝集成。

    二、环境准备

      本案例使用环境:jdk(1.8)、maven(3.2+)、zookeeper(3.4.10)、eclipse(Oxygen.3a Release (4.7.3a))、tomcat(tomcat8)

      a、搭建注册中心(jdk、maven、tomcat、eclipse集成可以自行搜索安装)

        1、本次实例使用zookeeper作为注册中心,下载地址:http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz

        也可以去官网下载想要的版本,官网地址:http://zookeeper.apache.org/releases.html

        2、解压 zookeeper-3.4.10.tar.gz,进入解压后conf目录下,复制zoo_sample.cfg文件,重命名为zoo.cfg即可

        3、进入解压后bin目录,点击zkServer.cmd即可

      b、搭建dubbo-admin控制台(可选)

        1、下载源码安装 ,下载地址:https://github.com/apache/incubator-dubbo/tree/dubbo-2.5.8

        也可以选择下载对应的版本。

        2、解压后,打开cmd进入dubbo-admin目录下,如我解压的目录为:D:Testdubbo-masterdubbo-admin,在cmd下输入命令:mvn clean install

        

        3、在target目录下生成dubbo-admin-2.5.8.war,然后将该war包放入tomcat的webapps目录下,启动tomcat, 访问localhost:[端口]/dubbo-admin-2.5.8,输入默认的用户名和密码:root/root

        例如我访问的地址为:http://localhost:8088/dubbo-admin-2.5.8/

        

    三、基于步骤二搭建的环境,使用ide开发JavaEE项目

      a、新建一个maven父项目dubbo-demo-master,和三个maven子模块dubbo-demo-interface、dubbo-demo-service、dubbo-demo-web(不知道如何新建百度搜索:eclipse搭建maven多module项目)

        1、完成后,添加相关项目依赖和插件,最后其dubbo-demo-master的pom.xml内容为(该maven工程packaging属性为pom),删除该工程的src目录(父工程不需要,只管理依赖):

        5、打开cmd进入dubbo-demo-master的pom.xml同级目录,执行mvn clean install ,其他子工程同理

      b、编辑dubbo-demo-interface工程,新增服务接口UserService和实体User,删除必要文件(如:webapp文件),修改完成后在pom.xml目录下使用命令:mvn clean install

      15、测试,创建app.properties配置的数据库和导入import.sql,运行UserMapperTest单元测试,如果出错就看日志定位。

      d、更新dubbo-demo-web的maven项目,编辑dubbo-demo-web工程,webapp只留下web.xml,删除不必要的jsp文件

      

      1、UserController.java

    复制代码
    package com.moy.maven.controller;
    
    import java.util.List;
    
    import org.moy.maven.domain.User;
    import org.moy.maven.service.UserService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    @RequestMapping("/users")
    public class UserController {
    
        @Autowired
        private UserService userService;
    
        @RequestMapping("/list")
        @ResponseBody
        public List<User> listUser() {
            List<User> userList = userService.findAll();
            return userList;
        }
    }
    复制代码

      2、log4j.properties

    按 Ctrl+C 复制代码

      3、spring-dubbo-consumer.xml

    按 Ctrl+C 复制代码
    按 Ctrl+C 复制代码

      4、spring-mvc.xml

    按 Ctrl+C 复制代码
    按 Ctrl+C 复制代码

      5、web.xml

    复制代码
    <!DOCTYPE web-app PUBLIC
     "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
     "http://java.sun.com/dtd/web-app_2_3.dtd" >
    
    <web-app>
        <display-name>Archetype Created Web Application</display-name>
        <!-- *** 编码拦截器开始(拦截器加载有顺序,放在最前面) *** -->
        <filter>
            <filter-name>CharacterEncodingFilter</filter-name>
            <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
            <async-supported>true</async-supported>
            <init-param>
                <param-name>encoding</param-name>
                <param-value>utf-8</param-value>
            </init-param>
        </filter>
        <filter-mapping>
            <filter-name>CharacterEncodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>
        <!-- === 编码拦截器结束 === -->
        
        <!-- *** 初始化SpringMVC开始 *** -->
        <servlet>
            <servlet-name>springMVC</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:spring-mvc.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>springMVC</servlet-name>
            <url-pattern>*.do</url-pattern>
        </servlet-mapping>
        <!-- === 初始化SpringMVC结束 === -->
    </web-app>
    复制代码

      6、index.html

    复制代码
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
        hello world!
    </body>
    </html>
    复制代码

    四、集成测试

       1、确保zookeeper是启动的

       2、打开cmd进入dubbo-demo-master的pom.xml同级目录下,运行命令:mvn clean install

       3、打开cmd进入dubbo-demo-service的pom.xml同级目录下,运行命令:mvn clean  tomcat:run -Dmaven.tomcat.port=8098

       4、打开cmd进入dubbo-demo-web的pom.xml同级目录下,运行命令:mvn clean  tomcat:run -Dmaven.tomcat.port=8099

       5、打开浏览器访问:http://localhost:8099/dubbo-demo-web/users/list.do接口,(接口数据是运行UserMapperTest单元测试来的)

       6、dubbo-demo-service工程实现接口,运行时向zookeeper注册接口信息,dubbo-demo-web工程只需要依赖接口,在通过spring原有的方式调用接口,其中dubbo帮我们从zookeeper中查找相应接口信息,通过默认dubbo协议帮我们完成了rpc调用。可以通过控制台http://localhost:8088/dubbo-admin-2.5.8/查看对应服务,对服务进行治理。
