手把手教你们搭建Spring MVC+MyBatis

1.首先导入所需要的包！需要的可以给我留下邮箱，我会发给你们

2.新建实体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的实现层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层接口IUserService

package com.fdream.service;public interface IUserService {public void add(String name,String pwd);}

6.新建service接口实现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@Transactionalpublic class UserServiceImpl implements IUserService {@Resourceprivate UserMapper userDao;@Overridepublic void add(String name, String pwd) {userDao.add(name, pwd);}}

7.新建控制层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;@Controllerpublic class UserController {@Autowiredprivate 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 连接数据库

<?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/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/txhttp://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.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/mvchttp://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><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:config/spring-*.xml</param-value></context-param><servlet><servlet-name>springMVC</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath*:config/spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springMVC</servlet-name><url-pattern>/</url-pattern></servlet-mapping><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

12.在WebRoot下新建一个add.jsp页面

<%@ 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下新建一个jsp文件夹，在里面新建一个scuccess.jsp页面,随便输出什么

<%@ 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"><!--<link rel="stylesheet" type="text/css" href="styles.css">-->  </head>    <body>    <h1>添加成功.</h1> <br>  </body></html>

14.部署启动tomcat，访问http://localhost:端口号/项目名
