Maven多模块SSM框架搭建

整合SSM和Maven多模块，搭建一个简单的开发架构，具体的做法如下：
1、首先建一个Maven的项目，使用eclipse新建other->Maven Project，类型必须选择为pom。创建成功后的pom.xml代码如下：

  4.0.0
  com.cn.itava
  Itava-main
  0.0.1-SNAPSHOT
  pom

2、在此基础上面新建各个Maven子模块，Web模块创建的时候选择pom类型为war，其他的为默认类型jar。

创建成功后在父模块会映射出这些包路径。

成功后父模块的pom.xml文件代码如下，添加相应的jar包（Spring 4.0.2.RELEASE mybatis 3.2.6 ):

  4.0.0
  com.cn.itava
  Itava-main
  0.0.1-SNAPSHOT
  pom

3、至此相应的包结构已经建好。
在Itava-web包中添加配置文件，spring-mvc.xml，spring-mybatis.xml,jdbc.properties,log4j.properties。包结构如下：

            class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
          
      

  

jdbc.properties内容如下：

log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n  

web.xml文件配置如下：

  
    xmlns="http://java.sun.com/xml/ns/javaee"  
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

        encodingFilter  
        org.springframework.web.filter.CharacterEncodingFilter  
        true

        /  
      
      
        /index.jsp  
      

  

5、Itava-dao实现如下:

这里面的user_sqlMap.xml，User.java，UserDao.java代码是通过mybatis-generator自动生成的。
可参照博客：http://blog.csdn.net/zhshulin/article/details/23912615

6、Itava-service实现如下：

[img]http://dl2.iteye.com/upload/attachment/0121/7358/707c9382-16a8-390b-bb2e-70c6b56f273b.png[/img]
UserService代码：

package org.itava.service;

import org.itava.pojo.User;


public interface UserService {
	 public User getUserById(int userId); 
}

UserServiceImpl代码：

package org.itava.service.impl;

import javax.annotation.Resource;

import org.itava.dao.UserDao;
import org.itava.pojo.User;
import org.itava.service.UserService;
import org.springframework.stereotype.Service;

@Service("userService")  
public class UserServiceImpl implements UserService {  
    @Resource  
    private UserDao userDao;

	public User getUserById(int userId) {
		return this.userDao.selectByPrimaryKey(userId);  
	}  


}

7、Itava-controller代码如下：
[img]http://dl2.iteye.com/upload/attachment/0121/7363/f304fef6-1f50-307f-ac49-6dd60b247a4d.png[/img]
UserController实现代码如下：

package org.itava.controller;
import javax.annotation.Resource;  
import javax.servlet.http.HttpServletRequest;  



import org.itava.pojo.User;
import org.itava.service.UserService;
import org.springframework.stereotype.Controller;  
import org.springframework.ui.Model;  
import org.springframework.web.bind.annotation.RequestMapping;  


@Controller  
@RequestMapping("/user")  
public class UserController {  
    @Resource  
    private UserService userService;  

    @RequestMapping("/showUser")  
    public String toIndex(HttpServletRequest request,Model model){  
        int userId = Integer.parseInt(request.getParameter("id"));  
        User user = this.userService.getUserById(userId);  
        model.addAttribute("user", user);  
        return "showUser";  
    }  
}  

8、在Itava-web中新建jsp文件，在pom.xml文件中配置tomcat服务器
