1、首先写一个简单登录界面
<body>
<form action="studentloginstu.action" method="post">
<input type="text" name="student.sname"/><br/>
<input type="text" name="student.spwd"/><br/>
<input type="submit" value="登录"/>
</form>
</body>
2、写一个相对应的Action
public class StudentAction extends ActionSupport{
private StudentBiz studentBiz;
private Student student;
public String loginstu() throws Exception {
System.out.println("登录.........");
//读取Subject对象
Subject subject=SecurityUtils.getSubject();
UsernamePasswordToken token=new UsernamePasswordToken(student.getSname(),student.getSage()+"");
System.out.println(student.getSname()+" "+student.getSage());
try {
//执行认证
subject.login(token);
} catch (Exception e) {
//e.printStackTrace();注释不打印错误
return "login";
}
return "success";
}
public StudentBiz getStudentBiz() {
return studentBiz;
}
public void setStudentBiz(StudentBiz studentBiz) {
this.studentBiz = studentBiz;
}
public Student getStudent() {
return student;
}
public void setStudent(Student student) {
this.student = student;
}
}
3、配置自定义realmpublic class MyRealm extends AuthorizingRealm{
private StudentBiz studentBiz;
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection arg0) {
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
//获取传递过来的数据
UsernamePasswordToken usernamePasswordToken=(UsernamePasswordToken) token;
String uname=usernamePasswordToken.getUsername();
String upass=usernamePasswordToken.getPassword().toString();
System.out.println("认证~："+uname+" "+upass);
//查询数据库
String pwd=studentBiz.getPwd(uname);
System.out.println("pwd:"+pwd);
//认证，把认证的结果 返回
SimpleAuthenticationInfo simpleAuthenticationInfo=new SimpleAuthenticationInfo(uname, pwd, this.getName());
return simpleAuthenticationInfo;
}
public StudentBiz getStudentBiz() {
return studentBiz;
}
public void setStudentBiz(StudentBiz studentBiz) {
this.studentBiz = studentBiz;
}
}
4、写一个spring配置文件（applicationContext-shiro.xml）
<?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.xsd">
<import resource="applicationContext-biz.xml"/>
<!-- 1.配置shiroFilter -->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<!-- 引入SecurityManager -->
<property name="securityManager" ref="securityManager"></property>
<!-- 配置登录界面-->
<property name="loginUrl" value="/login.jsp"></property>
<!-- 成功页面 -->
<property name="successUrl" value="/success.jsp"></property>
<!-- 过滤 登录才允许 -->
<property name="filterChainDefinitions">
<value>
/login.jsp*=anon
/success.jsp*=authc
/studentloginstu.action*=authc
</value>
</property>
</bean>
<!-- 2.配置SecurityManager -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="myRealm"></property>
</bean>
<!-- 3.配置自定义realm -->
<bean id="myRealm" class="com.zking.shiro.MyRealm">
<property name="studentBiz" ref="studentBizImp"></property>
</bean>
</beans>
5、配置web.xml文件<web-app>
<!-- 加载spring配置文件 -->
<!-- needed for ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-*.xml</param-value>
</context-param>
<!-- 加载shiro过滤 -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<!-- 加载struts2 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<!-- Bootstraps the root web application context before servlet initialization -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
6、struts配置文件<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="myPackage" extends="struts-default">
<action name="student*" class="allAction" method="{1}">
<result name="success">/success.jsp</result>
<result name="login">/login.jsp</result>
</action>
</package>
</struts>
