SpringMVC+Dubbo+Maven 简单的入门demo配置

一、 开发环境
1. 这边我用的是myeclipse10、 jdk1.7，maven4.0，tomcat 这几Java开发都要必备的工具我就不在这里赘述了，相信大家都能更好的配置好环境。
二、项目搭建
1. 搭建这种多个maven项目可以创建maven父工程来维护项目所需要的jar包，把几个项目工程公用的jar放到父工程中，其他的maven module 可以继承父工程的jar包，这样维护起来更方便
2. 今天我们分享的是不用父工程的，直接创建三个maven项目dubbo-api，service，web
3. dubbo-api ：主要放对外的接口，以及对象实体类，以及公共的工具类，这个项目是会打成jar包让service,web项目引用
service： 项目创建时packing选择war，主要是dubbo-api的业务实现，这个是要放到tomcat容器中运行
web: 项目创建时packing选择war，controller层控制跳转，这个是要放到tomcat容器中运行

项目搭建完成之后的结构图：

三、项目配置
1.dubbo-api项目
pom.xml配置文件：

<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.shang</groupId>
  <artifactId>dubbo-api</artifactId>
  <name>dubbo-api</name>
  <version>0.0.1-SNAPSHOT</version>
  <url>http://maven.apache.org</url>
  <packaging>jar</packaging>

   <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

新建api接口类TestServiceApi：

package com.demo.service;

import java.util.List;

import com.demo.domain.Token;


/**
 * 
 * @author SLQ
 *
 */
public interface TestServiceApi {

    public List<Token> helloWorld();

    public Token selectById(String token);

}

Token实体对象：

package com.demo.domain;

import java.io.Serializable;
import java.util.Date;

public class Token implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    private String token;

    private Integer userId;

    private Date tokenDate;

    private String ip;

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }

    public Integer getUserId() {
        return userId;
    }

    public void setUserId(Integer userId) {
        this.userId = userId;
    }

    public Date getTokenDate() {
        return tokenDate;
    }

    public void setTokenDate(Date tokenDate) {
        this.tokenDate = tokenDate;
    }

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

}

上面就是dubbo-api的文件配置以及需要创建的java类，这个项目需要打成jar包被另外两个项目引用

2.service项目配置
pom.xml文件：

创建实现类TestServiceImpl：

package com.test.service.impl;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import org.springframework.stereotype.Service;

import com.demo.domain.Token;
import com.demo.service.TestServiceApi;


@Service("testServiceApi")
public class TestServiceImpl implements TestServiceApi {


    @Override
    public List<Token> helloWorld() {

        List<Token> list = new ArrayList<Token>();
        Token token = new Token();
        token.setUserId(1);
        token.setIp("127.0.0.1");
        token.setToken("token");
        token.setTokenDate(new Date());
        list.add(token);
        return list;
    }

    @Override
    public Token selectById(String token) {

        return null;
    }

}

上面是service项目的配置文件，这个还需要一个web.xml文件，看下面web文件配置，把下面的web.xml文件复制过来把上面一句换成下面一句

<param-value>classpath*:/dubbo-config.xml</param-value>

<!--替换成-->
<param-value>classpath*:/applicationContext.xml</param-value>

这个项目在创建的时候packing是war，需要放到tomcat中运行的，我把我的数据库链接以及sql配置文件扫描也放进来了希望大家一起学习，进步

到现在为止项目搭建以及配置代码已经到一段落了，下面就到了启动项目的时候了

四、项目启动
1. dubbo项目启动还需要一个工具，相信大家已经知道了那就是zookeeper，这个插件附上官网下载地址：
http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
下载后解压
1.进入zookeeper-3.4.10/conf目录，把zoo_sample.cfg文件改名为zoo.cfg
2.修改tomcat端口号，因为zookeeper端口默认是8080，进入apache-tomcat\conf目录，修改server.xml文件，我的改成8083，你们自己看着改，你们喜欢就好！！！

2.进入zookeeper-3.4.10/bin目录，运行zkServer.cmd即可
3.运行客户端zkCli.cmd检查服务是否运行正常
4.zoo.cfg 文件可以指定日志文件地址

dataDir=F:/ProgramFiles/zookeeper-3.4.10/conf/tmp

zookeeper 启动之后，再启动tomcat，是不是成功了，这时我打开浏览器访问一下http://localhost:8083/web/con/test
哦，我犯了一个错，zookeeper 没有启动，差评！！！
重新启动zookeeper ，启动tomcat 输入访问地址

成功了！！！ 到现在我们的dubbo项目搭建完成了

五、dubbo后台管理平台
现在我们的Maven+SpringMVC+Dubbo已经搭建完成，如果我们想看服务消费者和服务提供着，那我们接下来还要做一件事那就是dubbo-admin的管理平台，当然这个dubbo已经给我们提供了，我只需要一个dubbo-admin-2.5.3.war包就可以了，当然这个war比较麻烦的是，在网上下载的可能不能适用自己的电脑，这个就需要自己动手打war了，个人建议自己去githu官网下载打包，地址：https://github.com/alibaba/dubbo 最好用2.5.3版本的比较稳定

如果上面一切都好dubbo-admin2.5.3.war已经打包成功，现在进入到apache-tomcat\webapps\ROOT目录下清空里面的所有文件，解压dubbo-admin2.5.3.war到这个目录下，
**注意：不要外层的dubbo-admin2.5.3

重新启动 zookeeper，tomcat 然后浏览器访问 http://localhost:8083/ 输入默认账号密码root

提供者

消费者

好了，上边只是简单介绍了这个后台管理系统，里面还有很多很强大的功能，我也暂时还没完全玩转，大家一起尝试下，分享下吧！

dubbo是一个很强大的分布式服务框架，致力于提供高性能和透明化的RPC远程服务调用方案，以及SOA服务治理方案，我用到的只是冰山一角，他的更多功能，大家一起研究下吧！这次分享就到这吧！
