myeclipse下使用maven搭建SSM（spring、springmvc、mybatis）框架

转自：http://blog.csdn.net/u012767369/article/details/70209400

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E:\MavenRepository\repo

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

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

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

IUserService.java

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

package com.chillax.service; import java.util.List; import com.chillax.dto.User; public interface IUserService { public User getUserById(int userId); public void insertUser(User user); public void addUser(User user); public List getAllUser(); }

UserServiceImpl.java

5、在WEB-INF文件夹下创建jsp文件夹，并添加userList.jsp、addUser.jsp、showUser.jsp
userList.jsp

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

6、创建数据库，并创建表

1 2 3 4 5 6 7 8 9 10 11 12

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。

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？

解答：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：出现如下图错误

解答：

问题5：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6：配置pom.xml文件后，下载jar包时出现以下错误

解答：在本地仓库找到错误所对应的jar包文件夹，将文件夹内的文件删除(出现这个错误时，文件夹内一般只有1个错误的文件)

在pom.xml中把关于这个jar包的配置代码删除保存，再重新把配置代码添加保存，让MyEclipse重新下载即可，下载成功后，文件夹内的内容应该如下图所示
