Springmvc

一、底层环境搭建

1、项目结构：

2、shrio的maven依赖

<dependency>
			<groupId>commons-logging</groupId>
			<artifactId>commons-logging</artifactId>
			<version>1.1.3</version>
		</dependency>
		<dependency>
			<groupId>org.apache.shiro</groupId>
			<artifactId>shiro-core</artifactId>
			<version>1.2.2</version>
		</dependency>
		<dependency>  
		    <groupId>org.apache.shiro</groupId>  
		    <artifactId>shiro-web</artifactId>  
		    <version>1.2.2</version>  
		</dependency>  
		<dependency>  
		    <groupId>org.apache.shiro</groupId>  
		    <artifactId>shiro-spring</artifactId>  
		    <version>1.2.2</version>  
		</dependency>  
		<dependency>  
		    <groupId>org.apache.shiro</groupId>  
		    <artifactId>shiro-ehcache</artifactId>  
		    <version>1.2.2</version>  
		</dependency>

3、web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2、applicationContext.xml的配置

</beans>

3、spring-mvc.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation=" 
                http://www.springframework.org/schema/beans 
                http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
                http://www.springframework.org/schema/context 
                http://www.springframework.org/schema/context/spring-context-3.1.xsd 
                http://www.springframework.org/schema/mvc 
                http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
                http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd" >
    
    <!-- 启动springMVC注解 -->
    <mvc:annotation-driven/>
    <context:component-scan base-package="com.libm">
      	<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />   
    	<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" /> 
    </context:component-scan>
   
    
    <!-- 自定义tiles -->
    <bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles3.TilesConfigurer"> 
    	<property name="definitions"> 
    		<list> 
    			<value>classpath:titles.xml</value> 
    		</list> 
    	</property> 
    </bean> 
    <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> 
    	<property name="viewClass"> 
    		<value> org.springframework.web.servlet.view.tiles3.TilesView </value> 
    	</property> 
    </bean>
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/" />
        <property name="suffix" value=".jsp" />
    </bean>
    
    <!-- <mvc:interceptors>
    	<mvc:interceptor>
    		<mvc:mapping path="/*.do"/>
    		<mvc:exclude-mapping path="/index.do"/>
    		<mvc:exclude-mapping path="/login.do"/>
    		<bean class="com.libm.interceptor.LoginInterceptor" />
    	</mvc:interceptor>
    </mvc:interceptors> -->
    
    <!-- 静态资源加载 -->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/js/" mapping="/js/**"/>
    <mvc:resources location="/images/" mapping="/images/**" />
    
</beans>

一、实现

1、实体类

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;


@Entity
public class User {
	private Integer id;  
    private String username;  
    private String password;  
    
    
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
	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;
	}
	
	
    
}

2、自定义MyShiro 身份验证

import java.util.List;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


import com.libm.domain.User;

@Service
public class MyShiro extends AuthorizingRealm {
	
	@Autowired
	private UserService userService;
	@Override
	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {

		
		return null;
	}

	@Override
	protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException {
		// UsernamePasswordToken对象用来存放提交的登录信息
		UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
		String username = token.getUsername();
		
		String password = String.valueOf(token.getPassword());
		// 查出是否有此用户 ，此处查询数据库
		User user = userService.chekLogin(username,password);
		if (user != null) {
			// 若存在，将此用户存放到登录认证info中
			return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName());
		}
		return null;
	}

}

3、index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!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>Login</title>
<script type="text/javascript" src="js/jquery-1.8.3.min.js"></script>

</head>
<body>
<form action="login.do" method="post">
	<div align="center">
		<table>
			<tr>
				<td>username</td>
				<td><input type="text" name="username"/> </td>
			</tr>
			<tr>
				<td>password</td>
				<td><input type="password" name="password"/> </td>
			</tr>
		</table>
		<button type="submit" id="loginBtn">login</button>
	</div>
	
</form>
</body>
</html>

4、LoginController

package com.libm.controller;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.libm.domain.User;

@Controller
public class LoginController {
	
	@RequestMapping(value="login")
	public String login(User user){
		Subject subject = SecurityUtils.getSubject();
		UsernamePasswordToken token = new UsernamePasswordToken(user.getUsername(), user.getPassword());
		try{
			token.setRememberMe(true);
			subject.login(token); 
			return "redirect:/home.do";
		}catch(Exception e){
			return "redirect:/index.do";
		}
		
	}
	
	@RequestMapping(value="home")
	public ModelAndView home(){
		ModelAndView mv = new ModelAndView("home");
		
		return mv;
	}
	@RequestMapping(value="index")
	public ModelAndView index(){
		ModelAndView mv = new ModelAndView("index");
		
		return mv;
	}
	@RequestMapping(value="logout")
	public String logout(){
		Subject subject = SecurityUtils.getSubject();
		subject.logout();
		return "redirect:/index.do";
	}
	
	
	
	
}
