我們已經完成了使用者的CRUD操作。本文我們來介紹下基于Shiro的登入認證操作。
登入認證
1.整合shiro
1.1 添加依賴
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
</dependency>
1.2 web.xml中注冊
<!-- shiro過慮器,DelegatingFilterProxy通過代理模式将spring容器中的bean和filter關聯起來 -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <!-- 設定true由servlet容器控制filter的生命周期 -->
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
<!-- 設定spring容器filter的bean id,如果不設定則找與filter-name一緻的bean -->
<init-param>
<param-name>targetBeanName</param-name>
<param-value>shiro</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
1.3 自定義Realm
/**
* 自定義的Realm
* @author 波波烤鴨
*
* [email protected]
*/
public class MyRealm extends AuthorizingRealm{
/**
* 認證的方法
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// TODO Auto-generated method stub
return null;
}
/**
* 授權的方法
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
// TODO Auto-generated method stub
return null;
}
}
1.4 添加shiro的配置檔案
<?xml version="1.0" encoding="UTF-8"?>
<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"
xmlns:aop="http://www.springframework.org/schema/aop"
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/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd">
<!-- 注冊自定義Realm -->
<bean class="com.bobo.realm.MyRealm" id="myRealm">
</bean>
<!-- 注冊SecurityManager -->
<bean class="org.apache.shiro.web.mgt.DefaultWebSecurityManager" id="securityManager">
<!-- 配置自定義Realm -->
<property name="realm" ref="myRealm"/>
</bean>
<!-- 注冊ShiroFilterFactoryBean 注意id必須和web.xml中注冊的targetBeanName的值一緻 -->
<bean class="org.apache.shiro.spring.web.ShiroFilterFactoryBean" id="shiro">
<!-- 注冊SecurityManager -->
<property name="securityManager" ref="securityManager"/>
<!-- 登入位址 如果使用者請求的的位址是 login.do 那麼會對該位址認證-->
<property name="loginUrl" value="/login.do"/>
<!-- 登入成功的跳轉位址 -->
<property name="successUrl" value="/main"/>
<!-- 通路未授權的頁面跳轉的位址 -->
<property name="unauthorizedUrl" value="/jsp/refuse.jsp"/>
<!-- 設定 過濾器鍊 -->
<property name="filterChainDefinitions">
<value>
<!--加載順序從上往下。
authc需要認證
anon可以匿名通路的資源
-->
/ = anon
/login = anon
/images/** = anon
/css/** = anon
/js/** = anon
/lib/** = anon
/login.do = authc
/** = authc
</value>
</property>
</bean>
</beans>
2.登入實作
2.1登入界面
http://localhost:8082/ 或者 http://localhost:8082/login
登入頁面代碼:
<%@ 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>歡迎登入背景管理系統</title>
<link href="/css/style.css" rel="stylesheet" type="text/css" />
<script language="JavaScript" src="/js/jquery.js"></script>
<script src="/js/cloud.js" type="text/javascript"></script>
<script language="javascript">
$(function() {
$('.loginbox').css({
'position' : 'absolute',
'left' : ($(window).width() - 692) / 2
});
$(window).resize(function() {
$('.loginbox').css({
'position' : 'absolute',
'left' : ($(window).width() - 692) / 2
});
})
});
</script>
</head>
<body
style="background-color: #1c77ac; background-image: url(/images/light.png); background-repeat: no-repeat; background-position: center top; overflow: hidden;">
<div id="mainBody">
<div id="cloud1" class="cloud"></div>
<div id="cloud2" class="cloud"></div>
</div>
<div class="logintop">
<span>歡迎登入背景管理界面平台</span>
<ul>
<li><a href="#">回首頁</a></li>
<li><a href="#">幫助</a></li>
<li><a href="#">關于</a></li>
</ul>
</div>
<div class="loginbody">
<span class="systemlogo"></span>
<div class="loginbox">
<form action="/login.do" method="post">
<ul>
<li><input name="username" type="text" class="loginuser" />
</li>
<li><input name="password" type="password" class="loginpwd" />
</li>
<li><input name="" type="submit" class="loginbtn" value="登入"/>
<label>
<input name="" type="checkbox" value="" checked="checked" />記住密碼
</label>
<label>
<ahref="#">忘記密碼?</a>
</label>
</li>
</ul>
</form>
</div>
</div>
<div style="display: none">
<script src='http://v7.cnzz.com/stat.php?id=155540&web_id=155540'
language='JavaScript' charset='gb2312'></script>
</div>
</body>
</html>
2.2登入認證
UserServiceImpl中修改query方法
@Override
public List<User> query(User user) {
UserExample example = new UserExample();
if(user!=null){
if(!"".equals(user.getUserName()) && user.getUserName()!= null){
// 根據賬号查詢
example.createCriteria().andUserNameEqualTo(user.getUserName());
}
}
return userMapper.selectByExample(example);
}
自定義Realm中完成認證的邏輯
@Resource
private IUserService userService;
/**
* 認證的方法
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// 擷取送出的賬号
UsernamePasswordToken t = (UsernamePasswordToken) token;
// 擷取登入的賬号
String userName = t.getUsername();
User user = new User();
user.setUserName(userName);
List<User> list = userService.query(user);
if(list == null || list.size() > 1){
// 賬号不存在或者使用者過多都傳回null
return null;
}
user = list.get(0);
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, user.getPassword(),"bobo");
return info;
}
完成controller邏輯
@Controller
public class LoginController {
/**
* 設定登入失敗跳轉的資源以及擷取失敗的資訊
*
* @param model
* @param request
* @return
*/
@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("----賬号不正确----->");
model.addAttribute("msg", "賬号不正确");
} else if (IncorrectCredentialsException.class.getName().equals(ex)) {
System.out.println("----密碼不正确----->");
model.addAttribute("msg", "密碼不正确");
} else {
System.out.println("----其他錯誤----->");
model.addAttribute("msg", "其他錯誤");
}
return "login";
}
}
3.測試
啟動後随便輸入一個位址,會發現重新跳回了登入頁面
http://localhost:8082/aaabcc
登入測試
賬号密碼正确的情況下進入了main.jsp頁面
4.退出功能
top.jsp中修改
LoginController中添加退出的方法
/**
* 登出
* @return
*/
@RequestMapping("/logout.do")
public String logout(){
SecurityUtils.getSubject().logout();
return "login";
}
操作測試即可
