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][Spring_Mybatis_SpringMVC_Maven_MySql]

最终效果如下：

**页面资源如下：**

好了，下面来简单说下过程吧！

准备工作：

先建表：

**\[sql\]** [ view plain][view plain] [ copy][view plain]

1.  drop table if exists user;  
2.   CREATE TABLE \`user\` (  
3.    \`id\` int(11) primary key auto\_increment,  
4.    \`name\` varchar(20)  NOT NULL,  
5.    \`age\` int(11) DEFAULT NULL,  
6.    \`birthday\` date DEFAULT NULL,  
7.    \`password\` varchar(20)  NOT NULL  
8.  ) ENGINE=InnoDB DEFAULT CHARSET=utf8;  
9.    
10.  insert into user values(1,'lin',12,'2013-12-01','123456');  
11.  insert into user values(2,'apple',34,'1999-12-01','123456');  
12.  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

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][Link 1]，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）

53. </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）

**\[html\]** [ view plain][view plain] [ copy][view plain]

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

![20151206163941544][]

**\[html\]** [ view plain][view plain] [ copy][view plain]

1.  <%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%>  
2.  <%  
3.      String url = request.getRequestURL().toString();  
4.      url = url.substring(0, url.indexOf('/', url.indexOf("//") + 2));  
5.      String context = request.getContextPath();  
6.      url += context;  
7.      application.setAttribute("ctx", url);  
8.  %>  
9.  <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">  
10. <html>  
11. <head>  
12. <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">  
13. <title>Insert title here</title>  
14. </head>  
15. <body>  
16.     <form action="$\{ctx\}/checkLogin.do" method="post">  
17.         username: <input type="text" name="username"><br>  
18.         password: <input type="password" name="password"><br>  
19.         <input type="submit" value="登录">  
20.     </form>  
21. </body>  
22. </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

**\[html\]** [ view plain][view plain] [ copy][view plain]

1.  <%@ page language="java" contentType="text/html; charset=UTF-8"  
2.      pageEncoding="UTF-8"%>  
3.  <%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags"%>  
4.  <%  
5.      String url = request.getRequestURL().toString();  
6.      url = url.substring(0, url.indexOf('/', url.indexOf("//") + 2));  
7.      String context = request.getContextPath();  
8.      url += context;  
9.      application.setAttribute("ctx", url);  
10. %>  
11. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">  
12. <html>  
13. <head>  
14. <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">  
15. <title>Shiro登陆实例</title>  
16. </head>  
17. <body>  
18.     <h1>Shiro登陆实例</h1><a href="$\{ctx\}/logout.html">退出</a>  
19.     <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>  
20.     <shiro:guest>    
21.         Hi there!  Please <a href="login.jsp">Login</a> or <a href="signup.jsp">Signup</a> today!    
22.     </shiro:guest>  
23.     <p>二、认证通过或已记住的用户</p>  
24.     <shiro:user>    
25.         Welcome back John!  Not John? Click <a href="login.jsp">here<a> to login.   
26.     </shiro:user>  
27.     <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>  
28.     <shiro:authenticated>    
29.         <a href="updateAccount.jsp">Update your contact information</a>.    
30.     </shiro:authenticated>  
31.     <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>  
32.     <shiro:notAuthenticated>    
33.         Please <a href="login.jsp">login</a> in order to update your credit card information.    
34.     </shiro:notAuthenticated>    
35.     <p>五、输出当前用户信息，通常为登录帐号信息</p>  
36.     Hello, <shiro:principal/>, how are you today?    
37.     <p>六、验证当前用户是否属于该角色</p>  
38.     <shiro:hasRole name="administrator">    
39.         <a href="admin.jsp">Administer the system</a>    
40.     </shiro:hasRole>    
41.     <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>  
42.     <shiro:lacksRole name="administrator">    
43.         Sorry, you are not allowed to administer the system.    
44.     </shiro:lacksRole>    
45.     <p>八、验证当前用户是否属于以下任意一个角色。</p>  
46.     <shiro:hasAnyRoles name="developer,manager,administrator">  
47.         You are either a developer,manager, or administrator.    
48.     </shiro:hasAnyRoles>  
49.    <p>九、验证当前用户权限。</p>  
50.     <shiro:hasPermission name="create">    
51.       <p>当前用户拥有增加的权限！！！！！！！！！！！！！</p>  
52.     </shiro:hasPermission>    
53.   
54.     <shiro:hasPermission name="delete">    
55.        <p>当前用户拥有删除的权限！！！！！！！！！！！！！</p>  
56.     </shiro:hasPermission>    
57. </body>  
58. </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][Link 2]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。

**\[java\]** [ view plain][view plain] [ copy][view plain]

1.  package com.lin.controller;  
2.

63.         // 取得用户名  
64.         String username = request.getParameter("username");  
65.         //取得 密码，并用MD5加密  
66.         String password = CipherUtil.generatePassword(request.getParameter("password"));

69.

71.         try \{  
72.             System.out.println("----------------------------");  
73.             if (!currentUser.isAuthenticated())\{//使用shiro来验证  
74.                 token.setRememberMe(true);  
75.                 currentUser.login(token);//验证角色和权限  
76.             \}  
77.             System.out.println("result: " + result);  
78.             result = "index";//验证成功  
79.         \} catch (Exception e) \{  
80.             logger.error(e.getMessage());  
81.             result = "login。do";//验证失败

85.     
86.     /\*\*

96.         currentUser.logout();    
97.         return result;    
98.     \}    
99.        
100. \}

再来看看效果吧！
