     摘要:本文采用了Spring+SpringMVC+Mybatis+Shiro+Msql来写了一个登陆验证的实例,下面来看看过程吧!整个工程基于Mavevn来创建,运行环境为JDK1.6+WIN7+tomcat7.

这里主要说了Shiro的搭建过程,Spring+SpringMVC+Mybatis的搭建过可以看这里Spring+Mybatis+SpringMVC+Maven+MySql搭建实例

好了,下面来简单说下过程吧!

准备工作:

先建表:

drop table if exists user;
 CREATE TABLE `user` (
  `id` int(11) primary key auto_increment,
  `name` varchar(20)  NOT NULL,
  `age` int(11) DEFAULT NULL,
  `birthday` date DEFAULT NULL,
  `password` varchar(20)  NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

 insert into user values(1,‘lin‘,12,‘2013-12-01‘,‘123456‘);
 insert into user values(2,‘apple‘,34,‘1999-12-01‘,‘123456‘);
 insert into user values(3,‘evankaka‘,23,‘2017-12-01‘,‘123456‘);

建好后,新建一个Maven的webApp的工程,记得把结构设置成上面的那样!

下面来看看一些代码和配置

1、POM文件

注意不要少导包了,如果项目出现红叉,一般都是JDK版本的设置问题,自己百度一下就可以解决

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2、自定义Shiro拦截器

   这里这个拦截器完成了用户名和密码的验证,验证成功后又给用赋角色和权限(注意,这里赋角色和权限我直接写进去了,没有使用数据库,一般都是要通过service层找到用户名后,再去数据库查该用户对应的角色以及权限,然后再加入到shiro中去)

技术分享

代码如下:

package com.lin.realm;

import java.util.HashSet;
import java.util.Set;

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.cache.Cache;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.SimplePrincipalCollection;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;

import com.lin.domain.User;
import com.lin.service.UserService;
import com.lin.utils.CipherUtil;

public class ShiroDbRealm extends AuthorizingRealm {
	private static Logger logger = LoggerFactory.getLogger(ShiroDbRealm.class);
	private static final String ALGORITHM = "MD5";
	
	@Autowired
	private UserService userService;

	public ShiroDbRealm() {
		super();
	}
	
	/**
	 * 验证登陆
	 */
	@Override
	protected AuthenticationInfo doGetAuthenticationInfo(
			AuthenticationToken authcToken) throws AuthenticationException {
		UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
		System.out.println(token.getUsername());
		User user = userService.findUserByLoginName(token.getUsername());
		System.out.println(user);
		CipherUtil cipher = new CipherUtil();//MD5加密
		if (user != null) {
			return new SimpleAuthenticationInfo(user.getName(), cipher.generatePassword(user.getPassword()), getName());
		}else{
			throw new AuthenticationException();
		}
	}

	/**
	 * 登陆成功之后,进行角色和权限验证
	 */
	@Override
	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
		/*这里应该根据userName使用role和permission 的serive层来做判断,并将对应 的权限加进来,下面简化了这一步*/
		Set<String> roleNames = new HashSet<String>();
	    Set<String> permissions = new HashSet<String>();
	    roleNames.add("admin");//添加角色。对应到index.jsp
	    roleNames.add("administrator");
	    permissions.add("create");//添加权限,对应到index.jsp
	    permissions.add("login.do?main");
	    permissions.add("login.do?logout");
		SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(roleNames);
	    info.setStringPermissions(permissions);
		return info;
	}


	/**
	 * 清除所有用户授权信息缓存.
	 */
	public void clearCachedAuthorizationInfo(String principal) {
		SimplePrincipalCollection principals = new SimplePrincipalCollection(principal, getName());
		clearCachedAuthorizationInfo(principals);
	}


	/**
	 * 清除所有用户授权信息缓存.
	 */
	public void clearAllCachedAuthorizationInfo() {
		Cache<Object, AuthorizationInfo> cache = getAuthorizationCache();
		if (cache != null) {
			for (Object key : cache.keys()) {
				cache.remove(key);
			}
		}
	}

//	@PostConstruct
//	public void initCredentialsMatcher() {//MD5鍔犲瘑
//		HashedCredentialsMatcher matcher = new HashedCredentialsMatcher(ALGORITHM);
//		setCredentialsMatcher(matcher);
//	}
}

3、shiro的配置文件 :spring-shiro.xml

内容如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
						http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"
	default-lazy-init="true">

	<description>Shiro Configuration</description>

	<!-- Shiro‘s main business-tier object for web-enabled applications -->
	<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
		<property name="realm" ref="shiroDbRealm" />
		<property name="cacheManager" ref="cacheManager" />
	</bean>

	<!-- 項目自定义的Realm -->
	<bean id="shiroDbRealm" class="com.lin.realm.ShiroDbRealm">
		<property name="cacheManager" ref="cacheManager" />
	</bean>

	<!-- Shiro Filter -->
	<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
		<property name="securityManager" ref="securityManager" />
		<property name="loginUrl" value="/login.do" />
		<property name="successUrl" value="/view/index.html" />
		<property name="unauthorizedUrl" value="/error/noperms.jsp" />
		<property name="filterChainDefinitions">
			<value>
				/index.html = authc
				/checkLogin.do = anon
				/login.do = anon
				/logout.html = anon
				/** = authc
			</value>
		</property>
	</bean>

	<!-- 用户授权信息Cache -->
	<bean id="cacheManager" class="org.apache.shiro.cache.MemoryConstrainedCacheManager" />

	<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->
	<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />

	<!-- AOP式方法级权限检查 -->
	<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
		depends-on="lifecycleBeanPostProcessor">
		<property name="proxyTargetClass" value="true" />
	</bean>

	<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
		<property name="securityManager" ref="securityManager" />
	</bean>
</beans>

这里简要说明下:

(1)

securityManager:这个属性是必须的。

loginUrl:没有登录的用户请求需要登录的页面时自动跳转到登录页面,不是必须的属性,不输入地址的话会自动寻找项目web项目的根目录下的”/login.jsp”页面。

successUrl:登录成功默认跳转页面,不配置则跳转至”/”。如果登陆前点击的一个需要登录的页面,则在登录自动跳转到那个需要登录的页面。不跳转到此。

unauthorizedUrl:没有权限默认跳转的页面。

(2)

anon:例子/admins/**=anon 没有参数,表示可以匿名使用。

authc:例如/admins/user/**=authc表示需要认证(登录)才能使用,没有参数

roles:例子/admins/user/**=roles[admin],参数可以写多个,多个时必须加上引号,并且参数之间用逗号分割,当有多个参数时,例如admins/user/**=roles["admin,guest"],每个参数通过才算通过,相当于hasAllRoles()方法。

perms:例子/admins/user/**=perms[user:add:*],参数可以写多个,多个时必须加上引号,并且参数之间用逗号分割,例如/admins/user/**=perms["user:add:*,user:modify:*"],当有多个参数时必须每个参数都通过才通过,想当于isPermitedAll()方法。

rest:例子/admins/user/**=rest[user],根据请求的方法,相当于/admins/user/**=perms[user:method] ,其中method为post,get,delete等。

port:例子/admins/user/**=port[8081],当请求的url的端口不是8081是跳转到schemal://serverName:8081?queryString,其中schmal是协议http或https等,serverName是你访问的host,8081是url配置里port的端口,queryString

是你访问的url里的?后面的参数。

authcBasic:例如/admins/user/**=authcBasic没有参数表示httpBasic认证

ssl:例子/admins/user/**=ssl没有参数,表示安全的url请求,协议为https

user:例如/admins/user/**=user没有参数表示必须存在用户,当登入操作时不做检查

注:anon,authcBasic,auchc,user是认证过滤器,

perms,roles,ssl,rest,port是授权过滤器

4、web.xml配置解读shiro的配置文件(上面的)

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

	</listener>
	
	<!-- 防止spring内存溢出监听器 -->
	<listener>
		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
	</listener>

	<!-- springMVC核心配置 -->

	<error-page>
		<error-code>401</error-code>
		<location>/WEB-INF/views/error/401.jsp</location>
	</error-page>
</web-app>

这里不仅配置了SpringMVC还要配置Shiro!

5、登陆页面login.jsp

以下是默认登陆的界面

技术分享

<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%>
<%
	String url = request.getRequestURL().toString();
	url = url.substring(0, url.indexOf(‘/‘, url.indexOf("//") + 2));
	String context = request.getContextPath();
	url += context;
	application.setAttribute("ctx", url);
%>
<!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>
	<form action="${ctx}/checkLogin.do" method="post">
		username: <input type="text" name="username"><br>
		password: <input type="password" name="password"><br>
		<input type="submit" value="登录">
	</form>
</body>
</html>

6、验证成功页面index.jsp

如果用户名和密码正确后,跳转到的页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags"%>
<%
	String url = request.getRequestURL().toString();
	url = url.substring(0, url.indexOf(‘/‘, url.indexOf("//") + 2));
	String context = request.getContextPath();
	url += context;
	application.setAttribute("ctx", url);
%>
<!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>Shiro登陆实例</title>
</head>
<body>
	<h1>Shiro登陆实例</h1><a href="${ctx}/logout.html">退出</a>
	<p>一、验证当前用户是否为"访客",即未认证(包含未记住)的用户</p>
	<shiro:guest>  
    	Hi there!  Please <a href="login.jsp">Login</a> or <a href="signup.jsp">Signup</a> today!  
	</shiro:guest>
	<p>二、认证通过或已记住的用户</p>
	<shiro:user>  
    	Welcome back John!  Not John? Click <a href="login.jsp">here<a> to login. 
	</shiro:user>
	<p>三、已认证通过的用户。不包含已记住的用户,这是与user标签的区别所在。</p>
	<shiro:authenticated>  
    	<a href="updateAccount.jsp">Update your contact information</a>.  
	</shiro:authenticated>
	<p>四、未认证通过用户,与authenticated标签相对应。与guest标签的区别是,该标签包含已记住用户。</p>
	<shiro:notAuthenticated>  
	    Please <a href="login.jsp">login</a> in order to update your credit card information.  
	</shiro:notAuthenticated>  
	<p>五、输出当前用户信息,通常为登录帐号信息</p>
	Hello, <shiro:principal/>, how are you today?  
	<p>六、验证当前用户是否属于该角色</p>
	<shiro:hasRole name="administrator">  
	    <a href="admin.jsp">Administer the system</a>  
	</shiro:hasRole>  
	<p>七、与hasRole标签逻辑相反,当用户不属于该角色时验证通过</p>
	<shiro:lacksRole name="administrator">  
	    Sorry, you are not allowed to administer the system.  
	</shiro:lacksRole>  
	<p>八、验证当前用户是否属于以下任意一个角色。</p>
	<shiro:hasAnyRoles name="developer,manager,administrator">
	    You are either a developer,manager, or administrator.  
	</shiro:hasAnyRoles>
   <p>九、验证当前用户权限。</p>
	<shiro:hasPermission name="create">  
	  <p>当前用户拥有增加的权限!!!!!!!!!!!!!</p>
	</shiro:hasPermission>  

	<shiro:hasPermission name="delete">  
	   <p>当前用户拥有删除的权限!!!!!!!!!!!!!</p>
	</shiro:hasPermission>  
</body>
</html>

其它页面就不说了,具体看工程吧!

7、controller层来看看

这里/{id}/showUser主要是来验证是否连接成功(现在无法测试了),当然在工程里你也可以到src/test/java里的包com.lin.service下的UserServiceTest.java,那里我也写了一个单元测试的类。

package com.lin.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import com.lin.domain.User;
import com.lin.realm.ShiroDbRealm;
import com.lin.service.UserService;
import com.lin.utils.CipherUtil;

@Controller
public class UserControler {
	private static Logger logger = LoggerFactory.getLogger(ShiroDbRealm.class);
	@Autowired
	private UserService userService;
	
	/**
	 * 验证springmvc与batis连接成功
	 * @param id
	 * @param request
	 * @return
	 */
	@RequestMapping("/{id}/showUser")
	public String showUser(@PathVariable int id, HttpServletRequest request) {
		User user = userService.getUserById(id);
		System.out.println(user.getName());
		request.setAttribute("user", user);
		return "showUser";
	}
	
	/**
	 * 初始登陆界面
	 * @param request
	 * @return
	 */
	@RequestMapping("/login.do")
	public String tologin(HttpServletRequest request, HttpServletResponse response, Model model){
		logger.debug("来自IP[" + request.getRemoteHost() + "]的访问");
		return "login";
	}
	
	/**
	 * 验证用户名和密码
	 * @param request
	 * @return
	 */
	@RequestMapping("/checkLogin.do")
	public String login(HttpServletRequest request) {
		String result = "login.do";
		// 取得用户名
		String username = request.getParameter("username");
		//取得 密码,并用MD5加密
		String password = CipherUtil.generatePassword(request.getParameter("password"));
		//String password = request.getParameter("password");
		UsernamePasswordToken token = new UsernamePasswordToken(username, password);
		
		Subject currentUser = SecurityUtils.getSubject();
		try {
			System.out.println("----------------------------");
			if (!currentUser.isAuthenticated()){//使用shiro来验证
				token.setRememberMe(true);
				currentUser.login(token);//验证角色和权限
			}
			System.out.println("result: " + result);
