SpringMVC和dubbo简单的整合（附Demo）

顺便记录下apache产品提供下载的网址：http://mirrors.shuosc.org/apache/

第一步：

下载zookeeper，网址：http://mirrors.shuosc.org/apache/zookeeper/

启动zookeeper，直接解压后，打开bin目录，双击zkServer.cmd，启动zookeeper服务。

若启动失败，我遇到的，有几个种原因，详情请打开cmd文件，在endlocal之前添加  pause  ，这样就不会闪退。

1、没配置java环境，在环境变量中，要JAVA_HOME这样配置变量，不能直接在path贴jdk路径。

2、在conf目录，将zoo_sample.cfg文件名修改成zoo.cfg。

第二步：

创建MAVEN JAVA工程，如下创建一个dubbo，一个接口模块，一个程序入口（SPRINGMVC）

3、interface项目，只要写一个类

package com.cwj.inter;

import org.springframework.stereotype.Service;

@Service
public interface DemoService {

    public String sayHello(String name);

}

pom.xml添加注释依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4、dubbo项目

  <artifactId>interface</artifactId>
  <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>
</project>

创建DemoServiceImpl类，继承DemoService

package com.cwj.dubbo;

import com.cwj.inter.DemoService;

public class DemoServiceImpl implements DemoService{

    public String sayHello(String name) {
        // TODO Auto-generated method stub
        System.out.println("hello:"+name);
        return "hello,"+name;
    }

}

配置applicationProvider.xml文件

<?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">

     <!-- 提供方应用信息，用于计算依赖关系 -->
    <dubbo:application name="app-provider"  />

    <!-- 使用zookeeper注册中心暴露服务地址 -->
    <dubbo:registry address="zookeeper://127.0.0.1:2181" /> 

    <!-- 用dubbo协议在20880端口暴露服务 -->
    <dubbo:protocol name="dubbo" port="20880" />

    <!-- 声明需要暴露的服务接口 -->
    <dubbo:service interface="com.cwj.inter.DemoService" ref="demoService" />

    <!-- 和本地bean一样实现服务 -->
    <bean id="demoService" class="com.cwj.dubbo.DemoServiceImpl" />

 </beans>

在App类中添加启动方法

package com.cwj.dubbo;

import java.io.IOException;

import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Hello world!
 *
 */
public class App {

    public static void main(String[] args) throws IOException {

        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationProvider.xml");
        context.start();

        System.out.println("-----dubbo开启-----");

        System.in.read(); // 为保证服务一直开着，利用输入流的阻塞来模拟

    }

}

开心的话也可以添加log4j.properties配置文件，没有配置有警告。程序员眼里只有错误把。

log4j.rootLogger=INFO,Console,File
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n  

log4j.appender.File = org.apache.log4j.RollingFileAppender
log4j.appender.File.File = logs/ssm.log
log4j.appender.File.MaxFileSize = 10MB
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

运行APP的main方法就可以成功启动了。启动前要先打开zk服务。

第五步：protal项目，配置MVC

        System.out.println(demoService.sayHello(name));
        request.setAttribute("hello",demoService.sayHello(name));
        return "test";
    }

}

启动项目成功连接，不想测试了。以后写博客尽量不贴代码。把自己遇到的问题给记录下来。 哪怕是几句话。

这个是一个过渡。加油。
