一、准备jar包
(1)Spring4的所有jar包
(2)Hibernate的所有jar包
(3)c3p0的jar包
(4)MySQL的jar包
(5)jackson的所有jar包
三、新建db.properties
user=root
password=
jdbcUrl=jdbc:mysql:///ssh
driverClass=com.mysql.jdbc.Driver
四、修改web.xml
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>classpath:applicationContext.xmlparam-value>
context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>

<param-value>classpath:springmvc.xmlparam-value>
init-param>
<load-on-startup>1load-on-startup>
servlet>
<servlet-mapping>
<servlet-name>springDispatcherServletservlet-name>
<url-pattern>/url-pattern>

filter>
<filter-mapping>
<filter-name>SpringOpenSessionInViewFilterfilter-name>
<url-pattern>/*url-pattern>
filter-mapping>
web-app>
五、新建springmvc.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"

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-4.1.xsd">
<context:component-scan base-package="com.dobeyue.spsh">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
<context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
context:component-scan>
<mvc:default-servlet-handler/>

@Table(name="users")
@Entity
@Component
public class User{
private Integer id;
@Email
private String username;
@NotEmpty
private String password;
public User() {
// TODO Auto-generated constructor stub
}
@GeneratedValue
@Id
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public User(Integer id, String username, String password) {
super();
this.id = id;
this.username = username;
this.password = password;
}
@Override
public String toString() {
return "User [id=" + id + ", username=" + username + ", password=" + password + "]";
}
}

import org.springframework.transaction.annotation.Transactional;
import com.dobeyue.spsh.dao.UserDao;
import com.dobeyue.spsh.entities.User;
@Repository("userDao")
public class UserDaoImpl implements UserDao {
@Autowired
private SessionFactory sessionFactory;
@Transactional(readOnly=true)
public User findUser(User user) {
return (User) sessionFactory.getCurrentSession()
.createQuery("FROM User u WHERE u.username = ? AND u.password = ? ")
.setString(0, user.getUsername()).setString(1, user.getPassword()).uniqueResult();
}
}
UserHandler.java
package com.dobeyue.spsh.handler;
import java.util.Map;
import javax.validation.Valid;

public void index(){}
// @ResponseBody
@RequestMapping(value="/doLogin",method=RequestMethod.POST)
public String login(@Valid @RequestParam("username") String username
,@RequestParam("password") String password,Map map,Model model,User user,BindingResult result){
// User user = userService.findUser(new User(null, username, password));
System.out.println(result);
user = userService.findUser(user);
if(user!=null){
map.put("user", user);
model.addAttribute("user", user);
return "success";
}else{
map.put("tip", "帐号或者密码错误");
return "success";
}
}
}

return userDao.findUser(user);
}
}
八、新建index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
<base href="<%=basePath%>">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta http-equiv="refresh"content="0.1; url=index"/>
<title>Insert title heretitle>
head>
<body>
<form action="doLogin" method="post" >
<input type="text" name="username"/>
<input type="password" name="password"/>
<input type="submit"/>
form>
body>
html>
九、新建success.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<html>
<head>
<base href="<%=basePath%>">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title heretitle>
head>
<body>
success
${user}
${user.username}
${user.password}
${tip}
<form:errors path="*"/>
<form:form action="doLogin" method="post" modelAttribute="user" >
<form:input path="username"/>
<form:input path="password"/>
<input type="submit"/>
form:form>
body>
html>
最后,运行即可。
