在ssm框架中初步的加入shiro

步骤

创建maven的war工程

加入依赖

    		</plugins>
    	</build>

配置web.xml

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

配置spring的配置文件(applicationContext-base.xml)

<context:property-placeholder location="classpath:db.properties"/>
    
    <context:component-scan base-package="com.sxt.service.impl"/>
    
    
    <bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource" >
    	<property name="driverClass" value="${driver}"></property>
    	<property name="jdbcUrl" value="${url}"></property>
    	<property name="user" value="${names}"></property>
    	<property name="password" value="${password}"></property>
    </bean>
    
    <bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactoryBean" >
    	
    	<property name="dataSource" ref="dataSource"/>
    	
    	<property name="configLocation" value="classpath:mybatis-config.xml"/>
    	
    	<property name="typeAliasesPackage" value="com.sxt.pojo"/>
    </bean>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" >
    	<property name="basePackage" value="com.sxt.mapper"/>
    </bean>

配置shiro的配置文件(applicationContext-shiro.xml)

<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"

    	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-4.3.xsd

    		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
    	
      
     	
     	<bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher" id="credentialsMatcher">

     	<bean class="org.apache.shiro.web.mgt.DefaultWebSecurityManager" id="securityManager">
     		
     		<property name="realm" ref="myRealm"/>
     	</bean>
     	
     	
     	<bean class="org.apache.shiro.spring.web.ShiroFilterFactoryBean" id="shiro">
     		
     		<property name="securityManager" ref="securityManager"/>
     		
     		<property name="loginUrl" value="/login.do"/>
     		
     		<property name="successUrl" value="/success.jsp"/>
     		
     		<property name="unauthorizedUrl" value="/refuse.jsp"/>
     		
     		<property name="filterChainDefinitions">
     			<value>
     				
     				/login.do=authc
     				/**=anon
     			</value>
     		</property>
     	</bean>
    </beans>

自定义Realm

package com.sxt.realm;
    
    import java.util.List;
    
    import javax.annotation.Resource;
    
    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.authz.AuthorizationInfo;
    import org.apache.shiro.realm.AuthorizingRealm;
    import org.apache.shiro.subject.PrincipalCollection;
    import org.apache.shiro.util.ByteSource;
    import org.apache.shiro.util.SimpleByteSource;
    
    import com.sxt.pojo.User;
    import com.sxt.service.UserService;
    
    public class MyRealm extends AuthorizingRealm {
    
    	@Resource
    	private UserService userService;
    
    	@Override
    	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection arg0) {
    
    		return null;
    	}
    
    	@Override
    	protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken arg0) throws AuthenticationException {
    		String userName = (String) arg0.getPrincipal();
    
    		  List<User> list = userService.login(userName);
    		if (list == null || list.size() != 1) {
    
    			return null;
    		}
    
    		User u = list.get(0);
    		// 获取密码
    		String pwd = u.getPassword();
    		 
    		// 验证密码
    		AuthenticationInfo  info = new SimpleAuthenticationInfo(userName , pwd, new SimpleByteSource(u.getSalt()), "myrealm");
    		// return info;
    		return info;
    	}
    
    }

控制层

package com.sxt.controller;
    
    import javax.servlet.http.HttpServletRequest;
    
    import org.apache.shiro.authc.IncorrectCredentialsException;
    import org.apache.shiro.authc.UnknownAccountException;
    import org.apache.shiro.web.filter.authc.FormAuthenticationFilter;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class LoginController {
    
    	@RequestMapping("/login.do")
    	public String login(Model model, HttpServletRequest request) {
    		
    		Object ex = request.getAttribute(FormAuthenticationFilter.DEFAULT_ERROR_KEY_ATTRIBUTE_NAME);
    		if (ex != null) {
    			System.out.println(ex.toString() + "----------");
    		}
    		if (UnknownAccountException.class.getName().equals(ex)) {
    			System.out.println("----账号不正确----->");
    			model.addAttribute("msg", "账号不正确");
    		} else if (IncorrectCredentialsException.class.getName().equals(ex)) {
    			System.out.println("----密码不正确----->");
    			model.addAttribute("msg", "密码不正确");
    		} else {
    			System.out.println("----其他错误----->");
    			model.addAttribute("msg", "其他错误");
    		}
    
    		return "login.jsp";
    	}
    }

dao层和service层就是普通的一个通过用户名查询用户

定义两个jsp

一个登陆成功后的登陆成功页面

一个登陆的页面

<%@ 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>Insert title here</title>
    </head>
    <body>
    	<h1>登录：${msg }</h1>
    	<form action="/login.do" method="post">
    		账号:<input type="text" name="username"><br>
    		密码:<input type="password" name="password"><br>
    		<input type="submit" value="登录">
    	</form>
    </body>
    </html>
