MyEclipse使用Maven创建web项目+搭建SSM框架教

使用maven已经有一段时间了，但项目是别人搭建好的，因此一直想着自己要学习搭建一下。网上找了些资料后，结合自己实验，花了点时间就搞好，老样子，写在博客上，免得日后忘记。

博文中的代码：链接：http://pan.baidu.com/s/1o7F6qEY 密码：rqd1

1.安装maven和配置

1、下载maven.apache.org/download.html，下载apache-maven-3.1.1-bin.zip，**-src.zip为Maven的源码

2、配置环境变量，打开系统环境变量新建一个M2_HOME将解压后的Maven存放路径放在此，然后在path路径下加

入史%M2_HOME%\bin路径

3、检测是否配置成功，打开命令行输入echo %M2_HOME%查看M2_HOME指向的Maven存放安装目录是否正

确，输入mvn -v查看是否能找到正确的mvn执行脚本

4、以后升级的话将M2_HOME的路径换为最新的安装目录就行

5、Maven实践：初次安装完后输入mvn help:system的命令，此时会打印出所有的Java系统属性和环境变量，然后

Maven会执行一个真正的任务将相应的所需的构件下载到本地仓库中包括pom和jar文件，然后用户在

C:\Users\Administrator\.m2下就能看到本地仓库了

6、用户需要复制M2_HOME/conf/setting.xml文件到C:/Users/Administrator/.m2/setting.xml，这样用户每次升

级后就不要在次修改setting.xml文件了

2.MyEclipse配置Maven

1、在本地创建一个文件夹MavenRepository，并在MavenRepository文件夹下创建文件夹repo。

2、进入Maven解压后的文件夹，进入conf文件夹，将settings.xml文件复制到上一步创建的MavenRepository文件

夹下

3、打开MavenRepository文件夹下的settings.xml文件，找到localRepository标签，此时是被注释掉的，我们解除

注释，然后配置步骤1中的repo路径，如<localRepository>E:\MavenRepository\repo</localRepository>

4、在MyEclipse中的Perferences进行如下配置，添加自己的Maven

5、User Settings设置为之前修改过的setting.xml

6、File->New->others，搜索maven，如果看到有Maven Project则代表配置成功。

3.MyEclipse使用maven创建web项目

1、创建一个maven项目

2、按照上面教程，即可创建出一个Maven项目，项目结构如下图

3、将JRE版本设置为1.7，可使用默认的或者自己导入

4、此时index.jsp会报以下错误

在pom.xml文件的dependencies节点下添加如下代码即可，添加完后，会下载对应的jar包

5、右键项目，选择Properties，进行如下配置

4.搭建Spring+SpringMVC+Mybatis框架

1、Maven引入项目用到的jar包，修改pom.xml后保存会自动下载，存放在之前配置的本地仓库中，即：

E:\MavenRepository\repo文件夹

pom.xml

6、创建数据库，并创建表

[sql] view plain copy

print ?

1. DROP TABLE IF EXISTS `user`;  
2.   
3. CREATE TABLE `user` (  
4.   `id` int(12) NOT NULL AUTO_INCREMENT,  
5.   `name` varchar(50) NOT NULL,  
6.   `password` varchar(50) NOT NULL,  
7.   `age` int(9) NOT NULL,  
8.   PRIMARY KEY (`id`)  
9. ) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8;  
10.   
11.   
12. insert  into `user`(`id`,`name`,`password`,`age`) values (1,'admin','admin',22);  

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (
  `id` int(12) NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `password` varchar(50) NOT NULL,
  `age` int(9) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8;


insert  into `user`(`id`,`name`,`password`,`age`) values (1,'admin','admin',22);

7、整个项目文件结构图

8、部署发布项目，进行测试

至此，框架搭建完成 。

5.常见问题

问题1：pom.xml文件里的代码到哪里找？

解答：http://www.mvnrepository.com/

问题2：新建MAVEN项目过程中，出现下图错误？

解决：在MyEclipse的安装目录找到myeclipse.ini，将分配的内存加大

问题3：新建完工程后出现以下错误？

解答：在pom.xml添加以下代码即可，添加完代码就会自动下载好jar包

问题4：修改pom.xml时出现以下错误？

解答：这是由于jar包没有正确下载导致的，找到错误的jar包位置，将文件夹里的文件删掉，将pom.xml里该jar包的配置代码删除后再重新写上，让MAVEN重新下载jar包即可。

问题5：出现以下错误？

解答：

问题6：出现以下错误？

解答：将项目的jre版本换成1.7或者以上的版本即可

问题7：出现以下错误，并且已经确定jre是1.7版本或者以上版本。

解答： 在pom.xml文件的<build></build>的标签中加入以下代码，然后Update Project（参照问题5）
