SpringMVC + Spring + Mybatis + Maven整合实例

2016-01-19 15:23 696 查看

一、说明：

目前工作中的开发框架主要是 spring ，使用的是 springMVC+ spring + spring JdbcTemplate ,最近学习了一下Mybatis、Maven这些内容，所以尝试使用 springMVC + Spring + Mybatis + Maven来搭建一个简单的demo ，功能很简单，主要是对于一个表的CRUD。

项目源码下载地址：github下载地址

项目结构图：

二、环境搭建流程

① 、新建一个Maven工程，并改项目为WEB项目，创建出相应的项目结构。

步骤：New---》Project----》Maven Project

之后选择Next：

选中 Create a simple project 选项，然后Next

然后点击Finish ，工程创建完成，结构如下：

然后，右键选中项目，打开Properties选项

将图中的Dynamic Web Module 选项去掉，点击OK保存

然后再次选中项目打开上述的菜单，并且选中Dynamic Web Module 选项，对话框出现下图的提示：

此时，点击下面的：Further configuration avaaliable选项，出现如下对话框

将web目录改为src/main/webapp ,之后ok保存，发现在项目的src/main.webapp下面多出了WEB-INF与META-INF文件，同时还生成了web.xml 文件，如下图：

②、配置相关的配置文件

1）、配置Maven的pom.xml文件，引入整合所需要的jar包：

XML Code

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

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

import com.elgin.entities.User;

import com.elgin.service.UserService;

@Controller

public class UserController

{

private Logger logger = Logger.getLogger(this.getClass());

@Autowired

private UserService userService;

/**

* @Title: addPage

* @Description: 用户添加页面

* @param mm

* @return 参数

*/

@RequestMapping("addpage.jhtml")

public String addPage(ModelMap mm)

{

logger.info("add page...");

return "/register";

}

/**

* @Title: Regiseter

* @Description: 用户添加操作

* @param request

* @param response

* @param user

* @throws IOException

* @throws ServletException 参数

*/

@RequestMapping("register.jhtml")

public void Regiseter(HttpServletRequest request, HttpServletResponse response, User user)throws
IOException, ServletException

{

int result =0;

if (user != null)

{

result = userService.addUser(user);

}

if (result >0)

{

logger.info("注册成功..");

response.sendRedirect("/allUser.jhtml");

}

else

{

logger.error("注册失败");

request.getRequestDispatcher("/500.jhtml").forward(request, response);

}

}

/**

* @Title: listUser

* @Description: 列表显示所有用户

* @param mm

* @return 参数

*/

@RequestMapping("allUser.jhtml")

public String listUser(ModelMap mm)

{

List<User> list = userService.getUserList();

mm.put("list", list);

return "/userlist";

}

/**

* @Title: editUser

* @Description: 用户信息编辑页面

* @param id

* @param mm

* @return 参数

*/

@RequestMapping("editUser.jhtml")

public String editUser(String id, ModelMap
mm)

{

User user = userService.getUser(Integer.parseInt(id));

mm.put("user", user);

return "/register";

}

/**

* @Title: updateUser

* @Description: 更新用户信息

*/

@RequestMapping("updateUser.jhtml")

public void updateUser(HttpServletRequest request, HttpServletResponse response, User user)throws
Exception

{

int result = userService.updateUser(user);

if (result >0)

{

logger.info("更新用户数据成功");

response.sendRedirect("/allUser.jhtml");

}

else

{

logger.error("更新用户数据失败");

request.getRequestDispatcher("/500.jhtml").forward(request, response);

}

}

response.sendRedirect("/allUser.jhtml");

}

else

{

logger.error("删除用户数据失败..");

request.getRequestDispatcher("/500.jhtml").forward(request, response);

}

}

}

10）、测试页面：

根据视图解析器的配置，在webapp/WEB-INF下新建jsp文件夹，用来保存相关页面：

register.jsp

JSP Code

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

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Register</title>

</head>

<body>

<c:if test="${empty user}">

<form action="register.jhtml" method="post">

</c:if>

<c:if test="${not empty user}">

<form action="updateUser.jhtml" method="post">

<input type="hidden" value="${user.id}" name="id">

</c:if>

<table>

<tr>

<td>用户名：</td>

<td><input type="text" name="username" value="${user.username}"></td>

</tr>

<tr>

<td>密码：</td>

<td><input type="password" name="password" value="${user.password}"></td>

</tr>

<tr>

<td>邮件：</td>

<td><input type="text" name="email" value="${user.email}"></td>

</tr>

<tr>

<td>电话：</td>

<td><input type="text" name="phone" value="${user.phone}"></td>

</tr>

<tr>

<td colspan="2" align="center"><input type="submit"
value="提交"></td>

</tr>

</table>

</form>

</body>

</html>

userlist.jsp :

JSP Code

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

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>User List</title>

</head>

<body>

<a href="addpage.jhtml"/>用户注册</a>

<br/>

<br/>

<span >所有用户</span>

<br/>

<br/>

<table border="2px" width="800" >

<tbody>

<tr>

<th>id</th>

<th>用户名</th>

<th>密码</th>

<th>邮箱</th>

<th>电话</th>

<th>操作</th>

</tr>

<c:forEach items="${list}" var="user">

<tr>

<td>${user.id}</td>

<td>${user.username}</td>

<td>${user.password}</td>

<td>${user.email}</td>

<td>${user.phone}</td>

<td>

<a href="deleteUser.jhtml?id=${user.id}">删除</a>

<a href="editUser.jhtml?id=${user.id}">编辑</a>

</td>

</tr>

</c:forEach>

</tbody>

</table>

</body>

</html>

三、测试结果：

将项目加载到tomcat，并启动。

访问：http://localhost:8080/addpage.jhtml ，进入编辑页面

输入数据点提交，数据保存成功并出现用户列表页面（编辑删除同理）：
