基于Maven的Spring + Spring MVC + Mybatis的环境搭建

老大想要做一个TimeSheet的东西，要管理公司员工每年的时间和effort. 反正还要个什么报表，老大发话了，很荣幸我有此机会又可以和刚进公司带我的老大一起做东西了，感觉很好。不过这个项目是一个partime job,自己在工作中抽时间来做。当然啦，堆码的事情肯定我来搞定啦。

项目开发，需求不是我定，所以在等待需求的时候，我就将环境先搭建起来。上次做了一个Spring + Spring MVC + Mybatis + Log4J + JUnit Test的环境搭建，这次也差不多，不过就是基于了Maven，同时也添加了事务管理。

首先，可以去了解一下maven，个人觉得这个东西就是JAR包管理方便，不用自己一个个去写，直接添加dependence就行了，不过有时候要注意哟，有可能重复的包含了某个JAR包，会报冲突的哟，亲！因为只有一个POM文件里指定JAR包，所以整个项目都很小的，一般就几MB，只有你在将该项目打成WAR包的时候，maven会自动的把三方JAR包放进项目，然后你就可以去部署到Tomcat的webapp下面了，放进去，重启Tomcat就OK。

1.开始搭建我的环境吧。首先，IDE我用的是eclipse的JEE版本。要保证装上了Maven哟，可以使用eclipse的Install New Software，URL地址是http://m2eclipse.sonatype.org/sites/m2e/，然后一步步走下去，安装好了过了会重启一次。给一个忠告哟，安装好了maven后，不要使用IDE里面的了，而是去官方下载一个，解压，然后让IDE的Maven指向你下载安装的，如图：

2.maven安装成功了，我们用Maven创建一个新的WEB项目。File—> New—> Other—>Maven Project.

选默认，下一步。在Select an Archetype里面种找到如下图所示

3.然后next，输入groupId:net.yuanmomo；artifactId:Test，然后finish，稍微等待一下，就创建好了。下面的是创建好了的一个初始的项目：

4.但是这个并不是默认的maven项目的标准结构.我们需要进行一些改动.

(1).在项目下创建一个Source Folder.

Folder Name:src/main/java

如下图所示:

(当然,还可以添加用于junit测试的src/test/java和src/test/resources

不过在此就不添加了.)

(2).在src/main/java中创建3个包(maven标准推荐是3层包结构)

(3).如果装的JDK是1.6的,更改JRE System Libary为1.6版本的.

(4).就src/main/webapp文件夹看做一个的WebRoot,然后创建js,css,jsp等文件夹。

这样.一个标准的maven web项目创建成功.

5.大家一看上面的项目结构，很熟悉吧。maven的项目结构路径有点讨厌，有点让人很烦。maven打WAR包的时候提取的东西是src/main/webapp下面的文件，然后打成一个WAR的WEB项目就可以部署了，但是，但是，我们在开发的时候，在使用eclipse里面的Tomcat调试的时候，tomcat却不是把src/main/webapp下面的文件部署到服务器。此时，如果你打开Server,然后add and remove，你在左边是找不到Test项目的，如下：

原因是因为Tomcat默认回去Test项目的路径下面去找WebRoot—>WEB-INF–>web.xml(WebRoot文件夹的名字可以不一样，可以使其它的，但是WEB-INF–>web.xml这两个名字不能变)，但是当前就找不到这几个目录。这个时候有两个解决办法：

(5.1). 在Test项目的路径下面，按照路径规则创建WebRoot，WEB-INF等文件夹，然后把上面的web.xml拷贝到新建的WEB-INF中去。放心吧，我上一个项目就是这样做的，不过这种方式打死都不可取的。你修改JSP的时候改的是下面的，maven打包的时候用的上面的。你还得拷贝过来，拷过去，麻烦，如果再有svn管理，累死你，晕死你，我们经常是调试编写的时候再下面做，最后提交的时候还得一个个拷贝上去，还出很多问题。所以建议采用第二种方式。

(5.2).转换该项目:

(1)在Test工程名上右键–>Properties–>Project Facets–>Convet to faceted form,

(2)勾上Dynamic Web Module,选择2.4版本。同时点击下方的further configuration available

(3)将默认的WebContent改成src/main/webapp

(4)一路点OK..此时在server视图中的tomcat server上点右键–>Add and Remove，就能看到该项目于，然后部署啦。

至此，我们已经创建好了一个合格的基于Maven的项目，也可以在Tomcat中部署。接下来，我们开始整合我们的J2EE框架。

6.先给出数据库的创建脚本，方便测试搭建是否成功。

SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";

–

– 数据库: `timesheet`

–

CREATE DATABASE `timesheet` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;

USE `timesheet`;

– ——————————————————–

–

– 表的结构 `testtable`

–

CREATE TABLE IF NOT EXISTS `testtable` (

`id` int(10) unsigned NOT NULL AUTO_INCREMENT,

`name` varchar(50) COLLATE utf8_bin DEFAULT NULL,

`date` timestamp NULL DEFAULT NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=1 ;

7.在pom文件中添加必要的jar包的dependence，可以从两个地方查询：

http://mvnrepository.com/

http://search.maven.org/

添加后的pom文件如下：

下载完成过后，点开项目左侧的Maven Dependencies，你就能看到很多的下载的JAR包了。

8. 修改web.xml，配置Spring，spring MVC，log4j，乱码处理等。

修改后保存该文件。

9.添加 log4j.properties,jdbc.properties等配置文件：

路径位置：

各个配置文件的内容如下：

log4j.appender.FILEOUT.File=${catalina.home}\\file.log

log4j.appender.fileout.MaxFileSize=100000KB

# default is true，append to the file; if false, the replace the log file whenever restart system

log4j.appender.FILEOUT.Append=true

#RollingFileAppender没有DatePattern这个属性

log4j.appender.FILEOUT.layout=org.apache.log4j.PatternLayout

#log4j.appender.CONSOLE.layout.ConversionPattern=[framework] %d – %c -%-4r [%t] %-5p %c %x – %m%n

<!– 这两个类的具体实现会在后面给出来–>

</bean>

</bean>

</beans>

此时，几个主要的配置文件我们已经加进来了，只有mybatis还有几个配置文件没有加进来。

10. 创建包，用于开发系统：

bean : 放pojo, java bean

business : 放业务层

conroller : 放控制层，主要负责接受请求和调用business,返回视图结果

dao : 放每个bean对应的接口

impl : dal 接口的具体实现

interceptor: 过滤器

resource : 资源包，比如文件路径，配置文件呀

test : 测试包

util : 工具包

web : 是装样子的哟，不是我这次要用的，是个空包。

10. 创建本次测试的java文件

(1). bean : TestTable.java:

package com.comverse.timesheet.web.bean;

import java.util.Date;

public class TestTable {

private int id;

private String name;

private Date birthday;

//setter and getter

…………….

}

(2). dao : ITestTableDAO.java

package com.comverse.timesheet.web.dao;

import com.comverse.timesheet.web.bean.TestTable;

public interface ITestTableDAO {

public boolean add(TestTable test) throws Exception;

}

(3). impl : ITestTableDAOImpl:

package com.comverse.timesheet.web.impl;

import com.comverse.timesheet.web.bean.TestTable;

import com.comverse.timesheet.web.dao.ITestTableDAO;

import com.comverse.timesheet.web.util.BasicSqlSupport;

public class ITestTableDAOImpl extends BasicSqlSupport implements ITestTableDAO {

@Override

public boolean add(TestTable test) throws Exception {

boolean flag=false;

int count=this.session.insert("com.comverse.timesheet.web.mapper.Test.add",test);

if(count>0){

flag=true;

}

return flag;

}

(4). business: TestBusiness.java

package com.comverse.timesheet.web.business;

import java.util.Date;

import javax.annotation.Resource;

import org.springframework.transaction.annotation.Transactional;

import com.comverse.timesheet.web.bean.TestTable;

import com.comverse.timesheet.web.dao.ITestTableDAO;

public class TestBusiness {

private ITestTableDAO testDAO=null;

public ITestTableDAO getTestDAO() {

return testDAO;

}

public void setTestDAO(ITestTableDAO testDAO) {

this.testDAO = testDAO;

}

public void add() throws Exception{

TestTable test=new TestTable();

test.setName("yuanmomo6");

test.setBirthday(new Date());

try {

testDAO.add(test);

} catch (Exception e) {

// TODO Auto-generated catch block

throw e;

}

(5). Controller : ResultController

package com.comverse.timesheet.web.controller;

import javax.annotation.Resource;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

import org.springframework.web.bind.annotation.RequestMapping;

import com.comverse.timesheet.web.business.TestBusiness;

@Controller

@RequestMapping("/result.do")

public class ResultController {

//将spring 配置文件中的bean 通过setter注入进来

@Resource(name="TestBusiness")

private TestBusiness testBusiness=null;

public void setTestBusiness(TestBusiness testBusiness) {

this.testBusiness = testBusiness;

}

@RequestMapping

public String viewUser(HttpServletRequest request, ModelMap modelMap)

throws Exception {

System.out.println("$$$$$$$$$$$$$$$$$$$$$you want to check the result.jsp+++++++++++++");

System.out.println("$$$$$$$$$$$$$$$$$$$$$ ready to insert +++++++++++++");

testBusiness.add();

System.out.println("$$$$$$$$$$$$$$$$$$$$$ insert completed +++++++++++++");

return "result";

}

(6). util : BasicSqlSupport.java所有的implementation类都会继承这个类，在ImplAndBusinessBeans.xml文件中注册的bean,都会注入一个sqlsession。例如上面的implementation就是继承了这个类。

package com.comverse.timesheet.web.util;

import org.apache.ibatis.session.SqlSession;

public class BasicSqlSupport{

protected SqlSession session;

public SqlSession getSession() {

return session;

}

public void setSession(SqlSession session) {

this.session = session;

}

11. 加入mybatis的配置文件：

(1). 为 TestTable bean 创建mapper文件，路径为com/comverse/timesheet/mybatis/mapper/Test.xml:

Test.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE mapper

PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"

"http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd%22>

<!– 定义一条查询语句，在bean的implementation中会引用此语句的id –>

<insert id="add" parameterType="Test"

useGeneratedKeys="true" keyProperty="classId">

INSERT INTO testtable (NAME,DATE)

VALUES(#{name},#{birthday})

</insert>

</mapper>

(1). 加入Mybatis的配置文件：在上面的ApplicationContext.xml文件中我们已经包含了SqlMapConfig.xml文件。在/com/comverse/timesheet/mybatis/下创建

SqlMapConfig.xml:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE configuration

PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN"

"http://ibatis.apache.org/dtd/ibatis-3-config.dtd%22>

<!– Entities 参数实体 –>

<!– com.comverse.timesheet.web.bean 包中的所有Bean, 取个别名 –>

<!– 比如TestTable类就用Test来表示–>

<typeAlias type="com.comverse.timesheet.web.bean.TestTable"

alias="Test" />

</typeAliases>

<!– 对应Bean类的xml配置文件的路径信息 –>

</mappers>

</configuration>

12. 框架的整合完成，项目的目录结构如下：

13. 编写一个测试页面，这个页面的路径在dispatcher-servlet.xml中已经确定—/WEB-INF/jsp/：

文件名在controller中已经定义–result, 后缀是 .jsp, 所以就是 result.jsp。

(1). result.jsp:

<%@page language="java" contentType="text/html; charset=utf-8"

pageEncoding="utf-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01

Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd%22>

<html>

<head>

<title>Insert title here</title>

</head>

<body>

<h1> 你插入数据成功了！！！</h1>

</body>

</html>

14.至此，我们的项目完成了，部署。部署之前检查一下problem框，看有没有问题。这次我突然遇到一个问题，我上个星期五的时候都没有遇到，今天就奇了怪了。不过没事，问题来就想办法解决它。

(1).在problem处发现这个问题

Description：

Classpath entry org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER will not be exported or published. Runtime ClassNotFoundExceptions may result. 如果部署了项目，启动，会报找不到类异常。

(2).问题的原因参考Loose classpath web libraries support

在项目上右键–>properties—>deployment Assembly–>add,选择 java build path entries，然后选中Maven dependencies–>finish–>OK,就能解决问题啦。

14. 一点小插曲过后，我们再次的部署项目，重新启动，看日志，项目成功的启动起来啦。

打开浏览器：访问http://localhost:8080/Test/，看到HelloWord

先查看数据的信息，没有数据，返回0行。

接着访问，http://localhost:8080/Test/result.do 看到结果了，高兴哇！！再看数据库

数据插入成功，至此，我们的项目搭建完整的完成了！！！如有错别字，请原谅，因为打字太痛苦啦！！谢谢大家！！

15. 检查一下我们的日志信息：

可以看出我们的事务也添加成功。

Spring MVC的流程：

request–>controller–>business–>implementation–>mysql
