手把手教你們搭建Spring MVC+MyBatis

1.首先導入所需要的包！需要的可以給我留下郵箱，我會發給你們

2.新建實體User

package com.fdream.entity;

public class User {
	private Integer id;
	private String name;
	private String pwd;
	public User() {
	}
	public User(String name, String pwd) {
		this.name = name;
		this.pwd = pwd;
	}
	public User(Integer id, String name, String pwd) {
		super();
		this.id = id;
		this.name = name;
		this.pwd = pwd;
	}
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPwd() {
		return pwd;
	}
	public void setPwd(String pwd) {
		this.pwd = pwd;
	}
}

3.新建接口UserMapper

package com.fdream.mapper;

public interface UserMapper {
	public void add(String name,String pwd);
}

4.dao的實現層userMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.fdream.mapper.UserMapper">
	<insert id="add" parameterType="User">
		insert into user (name,pwd) values (#{0},#{1});
	</insert>
</mapper>

5.新建service層接口IUserService

package com.fdream.service;

public interface IUserService {
	public void add(String name,String pwd);
}

6.新建service接口實現UserServiceImpl

package com.fdream.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.fdream.mapper.UserMapper;
import com.fdream.service.IUserService;
@Service
@Transactional
public class UserServiceImpl implements IUserService {
	@Resource
	private UserMapper userDao;
	@Override
	public void add(String name, String pwd) {
		userDao.add(name, pwd);
	}

}

7.新建控制層UserController

package com.fdream.controller;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.codec.digest.DigestUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.fdream.entity.User;
import com.fdream.service.IUserService;

@Controller
public class UserController {
	@Autowired
	private IUserService userService;
	@RequestMapping("/add")
	public String add(User user,HttpServletRequest request){
		userService.add(user.getName(), DigestUtils.md5Hex(user.getPwd()));
		return "/scuccess";
	}
}

8.新建spring-common.xml 連接數據庫

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans
		http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
		http://www.springframework.org/schema/context
		http://www.springframework.org/schema/context/spring-context-4.0.xsd
		http://www.springframework.org/schema/tx
		http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

	<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost:3306/ssh?characterEncoding=UTF-8" />
		<property name="username" value="root" />
		<property name="password" value="root" />
	</bean>

	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="configLocation" value="classpath:config/mybatis-config.xml" /> 
	</bean>

	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.fdream.mapper"></property>
		<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
	</bean>

	<bean id="txManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>

	<tx:annotation-driven transaction-manager="txManager" />

</beans>

9.新建映射文件mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<typeAliases>
		<typeAlias alias="User" type="com.fdream.entity.User"/>
	</typeAliases>
	<mappers>
		<mapper resource="com/fdream/mapper/userMapper.xml"/>
	</mappers>
</configuration>

10.新建spring mvc配置文件spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-4.0.xsd
	http://www.springframework.org/schema/mvc
	http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
	
	<context:component-scan base-package="com.fdream" />
	<mvc:annotation-driven />
	<mvc:resources mapping="/img/**" location="/img/" />
	<mvc:resources mapping="/js/**" location="/js/" />
	<mvc:resources mapping="/css/**" location="/css/" />
	<mvc:resources mapping="/html/**" location="/html/" />
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>
</beans>

11.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	
	<welcome-file-list>
		<welcome-file>add.jsp</welcome-file>
	</welcome-file-list>
		
	<listener>

	</filter-mapping>
</web-app>

12.在WebRoot下新建一個add.jsp頁面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'add.jsp' starting page</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">

  </head>
  
  <body>
    <form action="<%=basePath%>add" method="post">
    	name:<input type="text" name="name"/><br/>
    	pwd:<input type="password" name="pwd"><br/>
    	<input type="submit" value="提交"/>
    </form>
  </body>
</html>

13.在WEB-INF下新建一個jsp文件夾，在裏面新建一個scuccess.jsp頁面,隨便輸出什麼

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'scuccess.jsp' starting page</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--

	-->

  </head>
  
  <body>
    	<h1>添加成功.</h1> <br>
  </body>
</html>

14.部署啓動tomcat，訪問http://localhost:端口號/項目名
