web工程使用spring mvc+shiro进行权限控制
第1步:引入shiro相关jar包
ehcache-core-2.5.0.jar
shiro-ehcache-1.2.3.jar
shiro-core-1.2.3.jar
shiro-web-1.2.3.jar
shiro-spring-1.2.3.jar
第二步:web.xml配置
<!-- shiro的filter --> <!-- shiro过虑器,DelegatingFilterProxy通过代理模式将spring容器中的bean和filter关联起来 --> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <!-- 设置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> <!-- 设置spring容器filter的bean id,如果不设置则找与filter-name一致的bean--> <init-param> <param-name>targetBeanName</param-name> <param-value>shiroFilter</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
第三步:applicationContext-shiro.xml配置
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "> <!-- web.xml中shiro的filter对应的bean --> <!-- Shiro 的Web过滤器 --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager" /> <!-- loginUrl认证提交地址,如果没有认证将会请求此地址进行认证,请求此地址将由formAuthenticationFilter进行表单认证 --> <property name="loginUrl" value="/login.action" /> <!-- 认证成功统一跳转到first.action,建议不配置,shiro认证成功自动到上一个请求路径 --> <property name="successUrl" value="/first.action"/> <!-- 通过unauthorizedUrl指定没有权限操作时跳转页面--> <property name="unauthorizedUrl" value="/refuse.jsp" /> <!-- 自定义filter配置 --> <property name="filters"> <map> <!-- 将自定义 的FormAuthenticationFilter注入shiroFilter中--> <entry key="authc" value-ref="formAuthenticationFilter" /> </map> </property> <!-- 过虑器链定义,从上向下顺序执行,一般将/**放在最下边 --> <property name="filterChainDefinitions"> <value> <!-- 对静态资源设置匿名访问 --> /images/** = anon /js/** = anon /styles/** = anon <!-- 验证码,可匿名访问 --> /validatecode.jsp = anon <!-- 请求 logout.action地址,shiro去清除session--> /logout.action = logout <!--商品查询需要商品查询权限 ,取消url拦截配置,使用注解授权方式 --> <!-- /items/queryItems.action = perms[item:query] /items/editItems.action = perms[item:edit] --> <!-- 配置记住我或认证通过可以访问的地址 --> /index.jsp = user /first.action = user /welcome.jsp = user <!-- /** = authc 所有url都必须认证通过才可以访问--> /** = authc <!-- /** = anon所有url都可以匿名访问 --> </value> </property> </bean> <!-- securityManager安全管理器 --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="customRealm" /> <!-- 注入缓存管理器 --> <property name="cacheManager" ref="cacheManager"/> <!-- 注入session管理器 --> <property name="sessionManager" ref="sessionManager" /> <!-- 记住我 --> <property name="rememberMeManager" ref="rememberMeManager"/> </bean> <!-- realm --> <bean id="customRealm" class="自定义类realm类全名"> <!-- 将凭证匹配器设置到realm中,realm按照凭证匹配器的要求进行散列 --> <property name="credentialsMatcher" ref="credentialsMatcher"/> </bean> <!-- 凭证匹配器 --> <bean id="credentialsMatcher" class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <property name="hashAlgorithmName" value="md5" /> <property name="hashIterations" value="1" /> </bean> <!-- 缓存管理器 --> <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> <property name="cacheManagerConfigFile" value="classpath:shiro-ehcache.xml"/> </bean> <!-- 会话管理器 --> <bean id="sessionManager" class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager"> <!-- session的失效时长,单位毫秒 --> <property name="globalSessionTimeout" value="600000"/> <!-- 删除失效的session --> <property name="deleteInvalidSessions" value="true"/> </bean> <!-- 自定义form认证过虑器 --> <!-- 基于Form表单的身份验证过滤器,不配置将也会注册此过虑器,表单中的用户账号、密码及loginurl将采用默认值,建议配置 --> <bean id="formAuthenticationFilter" class="自定义类全名 "> <!-- 表单中账号的input名称 --> <property name="usernameParam" value="username" /> <!-- 表单中密码的input名称 --> <property name="passwordParam" value="password" /> <!-- 记住我input的名称 --> <property name="rememberMeParam" value="rememberMe"/> </bean> <!-- rememberMeManager管理器,写cookie,取出cookie生成用户信息 --> <bean id="rememberMeManager" class="org.apache.shiro.web.mgt.CookieRememberMeManager"> <property name="cookie" ref="rememberMeCookie" /> </bean> <!-- 记住我cookie --> <bean id="rememberMeCookie" class="org.apache.shiro.web.servlet.SimpleCookie"> <!-- rememberMe是cookie的名字 --> <constructor-arg value="rememberMe" /> <!-- 记住我cookie生效时间30天 --> <property name="maxAge" value="2592000" /> </bean> </beans>
第4步:在spring mvc配置中启用shiro注解支持
<!-- 开启aop,对类代理 --> <aop:config proxy-target-class="true"></aop:config> <!-- 开启shiro注解支持 --> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager" /> </bean>
第5步:自定义Realm和FormAuthenticationFilter
public class CustomRealm extends AuthorizingRealm { //注入service @Autowired private SysService sysService; // 设置realm的名称 @Override public void setName(String name) { super.setName("customRealm"); } //realm的认证方法,从数据库查询用户信息 @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token) throws AuthenticationException { // token是用户输入的用户名和密码 // 第一步从token中取出用户名 String userCode = (String) token.getPrincipal(); // 第二步:根据用户输入的userCode从数据库查询 SysUser sysUser = null; try { sysUser = sysService.findSysUserByUserCode(userCode); } catch (Exception e1) { // TODO Auto-generated catch block e1.printStackTrace(); } // 如果查询不到返回null if(sysUser==null){// return null; } // 从数据库查询到密码 String password = sysUser.getPassword(); //盐 String salt = sysUser.getSalt(); // 如果查询到返回认证信息AuthenticationInfo //activeUser就是用户身份信息 ActiveUser activeUser = new ActiveUser(); activeUser.setUserid(sysUser.getId()); activeUser.setUsercode(sysUser.getUsercode()); activeUser.setUsername(sysUser.getUsername()); //.. //根据用户id取出菜单 List<SysPermission> menus = null; try { //通过service取出菜单 menus = sysService.findMenuListByUserId(sysUser.getId()); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } //将用户菜单 设置到activeUser activeUser.setMenus(menus); //将activeUser设置simpleAuthenticationInfo SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo( activeUser, password,ByteSource.Util.bytes(salt), this.getName()); return simpleAuthenticationInfo; } // 用于授权 @Override protected AuthorizationInfo doGetAuthorizationInfo( PrincipalCollection principals) { //从 principals获取主身份信息 //将getPrimaryPrincipal方法返回值转为真实身份类型(在上边的doGetAuthenticationInfo认证通过填充到SimpleAuthenticationInfo中身份类型), ActiveUser activeUser = (ActiveUser) principals.getPrimaryPrincipal(); //根据身份信息获取权限信息 //从数据库获取到权限数据 List<SysPermission> permissionList = null; try { permissionList = sysService.findPermissionListByUserId(activeUser.getUserid()); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } //单独定一个集合对象 List<String> permissions = new ArrayList<String>(); if(permissionList!=null){ for(SysPermission sysPermission:permissionList){ //将数据库中的权限标签 符放入集合 permissions.add(sysPermission.getPercode()); } } //查到权限数据,返回授权信息(要包括 上边的permissions) SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo(); //将上边查询到授权信息填充到simpleAuthorizationInfo对象中 simpleAuthorizationInfo.addStringPermissions(permissions); return simpleAuthorizationInfo; } //清除缓存 public void clearCached() { PrincipalCollection principals = SecurityUtils.getSubject().getPrincipals(); super.clearCache(principals); } }
public class CustomFormAuthenticationFilter extends FormAuthenticationFilter { //原FormAuthenticationFilter的认证方法 @Override protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception { //在这里进行验证码的校验 //从session获取正确验证码 HttpServletRequest httpServletRequest = (HttpServletRequest) request; HttpSession session =httpServletRequest.getSession(); //取出session的验证码(正确的验证码) String validateCode = (String) session.getAttribute("validateCode"); //取出页面的验证码 //输入的验证和session中的验证进行对比 String randomcode = httpServletRequest.getParameter("randomcode"); if(randomcode!=null && validateCode!=null && !randomcode.equals(validateCode)){ //如果校验失败,将验证码错误失败信息,通过shiroLoginFailure设置到request中 httpServletRequest.setAttribute("shiroLoginFailure", "randomCodeError"); //拒绝访问,不再校验账号和密码 return true; } return super.onAccessDenied(request, response); } }
第六步:用户登录控制层代码
@RequestMapping("login") public String login(HttpServletRequest request)throws Exception{ //如果登陆失败从request中获取认证异常信息,shiroLoginFailure就是shiro异常类的全限定名 String exceptionClassName = (String) request.getAttribute("shiroLoginFailure"); //根据shiro返回的异常类路径判断,抛出指定异常信息 if(exceptionClassName!=null){ if (UnknownAccountException.class.getName().equals(exceptionClassName)) { //最终会抛给异常处理器 throw new CustomException("账号不存在"); } else if (IncorrectCredentialsException.class.getName().equals( exceptionClassName)) { throw new CustomException("用户名/密码错误"); } else if("randomCodeError".equals(exceptionClassName)){ throw new CustomException("验证码错误 "); }else { throw new Exception();//最终在异常处理器生成未知错误 } } //此方法不处理登陆成功(认证成功),shiro认证成功会自动跳转到上一个请求路径 //登陆失败还到login页面 return "login"; }
