1. 整合ssm并且实现用户登录和菜单权限。
2. 将shiro整合到ssm中
a).添加shiro相关jar包
b).在web.xml种添加shiro的配置
<!-- 配置shirofilter 通过代理来配置,对象由spring容器来创建的,但是交由servlet容器来管理 --> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <!-- 表示bean的生命周期有servlet来管理 --> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> <init-param> <!--表示在spring容器中bean的id,如果不配置该属性,那么默认和该filter的name一致--> <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>
c)在src下添加 applicationContext-shiro.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 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 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <!-- 配置securityManager --> <property name="securityManager" ref="securityManager"/> <!-- 当访问需要认证的资源时,如果没有认证,那么将自动跳转到该url; 如果不配置该属性 默认情况下会到根路径下的login.jsp --> <property name="loginUrl" value="/login"></property> <!-- 配置认证成功后 跳转到那个url上,通常不设置,如果不设置,那么默认认证成功后跳转上上一个url --> <property name="successUrl" value="/index"></property> <!-- 配置用户没有权限访问资源时 跳转的页面 --> <property name="unauthorizedUrl" value="/refuse"/> <!-- 配置shiro的过滤器链 --> <property name="filterChainDefinitions"> <value> /toLogin=anon /login=authc /logout=logout /**=authc </value> </property> </bean> <!-- 配置securityManager --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="userRealm"/> </bean> <bean id="userRealm" class="cn.wh.realm.UserRealm"/> </beans>
d) 修改loginController中登陆方法
//登录 @RequestMapping("/login") public ModelAndView login(HttpServletRequest request){ ModelAndView mv=new ModelAndView("login"); String className=(String)request.getAttribute("shiroLoginFailure"); if(UnknownAccountException.class.getName().equals(className)){ //抛出自定义异常 mv.addObject("msg", "用户名或密码错误!!"); }else if(IncorrectCredentialsException.class.getName().equals(className)){ //抛出自定义异常 mv.addObject("msg", "用户名或密码错误!!"); }else{ mv.addObject("msg", "系统异常!!"); } return mv; }
e) 添加自定义Realm:UserRealm
public class UserRealm extends AuthorizingRealm{ @Override public String getName() { return "userRealm"; } //认证 @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token) throws AuthenticationException { String username = token.getPrincipal().toString(); String pwd ="1111"; return new SimpleAuthenticationInfo(username, pwd,getName()); } //授权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principal) { return null; } }
f)修改UserRealm实现身份认证
public class UserRealm extends AuthorizingRealm{ @Autowired private UserService userService; @Autowired private PermissionService permissionService; @Override public String getName() { return "userRealm"; } //认证 @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token) throws AuthenticationException { String username = token.getPrincipal().toString(); User user = userService.findUserByName(username); //设置该user的菜单 if(user!=null){ user.setMenus(permissionService.findByUserId(user.getId())); } return new SimpleAuthenticationInfo(user, user.getPwd(),getName()); } //授权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principal) { return null; } }
e)凭证匹配器配置
<!-- 配置自定义realm --> <bean id="userRealm" class="cn.sxt.realm.UserRealm"> <property name="credentialsMatcher" ref="credentialsMatcher"/> </bean> <!-- 配置凭证匹配器 --> <bean id="credentialsMatcher" class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <property name="hashAlgorithmName" value="md5"/> <property name="hashIterations" value="2"/> </bean>
userRealm要相应改变
//认证 @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token) throws AuthenticationException { String username = token.getPrincipal().toString(); User user = userService.findUserByName(username); //设置该user的菜单 if(user!=null){ user.setMenus(permissionService.findByUserId(user.getId())); } return new SimpleAuthenticationInfo(user, user.getPwd(),ByteSource.Util.bytes(user.getSalt()),getName()); }
logout配置,默认退出后跳转到跟路径下,如果需要改变则需从新配置logout过滤器,过滤器bean的id不能改变,只能为logout
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <!-- 配置securityManager --> <property name="securityManager" ref="securityManager"/> <!-- 当访问需要认证的资源时,如果没有认证,那么将自动跳转到该url; 如果不配置该属性 默认情况下会到根路径下的login.jsp --> <property name="loginUrl" value="/login"></property> <!-- 配置认证成功后 跳转到那个url上,通常不设置,如果不设置,那么默认认证成功后跳转上上一个url --> <property name="successUrl" value="/index"></property> <!-- 配置用户没有权限访问资源时 跳转的页面 --> <property name="unauthorizedUrl" value="/refuse"/> <!-- 配置shiro的过滤器链 logout默认退出后跳转到根路径下,可以从新指定 --> <property name="filterChainDefinitions"> <value> /toLogin=anon /login=authc /logout=logout /js/**=anon /css/**=anon /images/**=anon /**=anon </value> </property> </bean> <!-- 配置logout过滤器 --> <bean id="logout" class="org.apache.shiro.web.filter.authc.LogoutFilter"> <property name="redirectUrl" value="/toLogin"/> </bean>
改变登陆时的表单域名称,需要从新配置authc过滤器
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <!-- 配置securityManager --> <property name="securityManager" ref="securityManager"/> <!-- 当访问需要认证的资源时,如果没有认证,那么将自动跳转到该url; 如果不配置该属性 默认情况下会到根路径下的login.jsp --> <property name="loginUrl" value="/login"></property> <!-- 配置认证成功后 跳转到那个url上,通常不设置,如果不设置,那么默认认证成功后跳转上上一个url --> <property name="successUrl" value="/index"></property> <!-- 配置用户没有权限访问资源时 跳转的页面 --> <property name="unauthorizedUrl" value="/refuse"/> <!-- 配置shiro的过滤器链 logout默认退出后跳转到根路径下,可以从新指定 --> <property name="filterChainDefinitions"> <value> /toLogin=anon /login=authc /logout=logout /js/**=anon /css/**=anon /images/**=anon /**=anon </value> </property> </bean> <!-- 配置authc过滤器 --> <bean id="authc" class="org.apache.shiro.web.filter.authc.FormAuthenticationFilter"> <property name="usernameParam" value="name"/> <property name="passwordParam" value="pwd"/> </bean>
登陆页面的改变:
<form id="slick-login" action="login" method="post"> <label for="username">username</label><input type="text" name="name" class="placeholder" placeholder="用户名"> <label for="password">password</label><input type="password" name="pwd" class="placeholder" placeholder="密码"> <input type="submit" value="Log In"> </form>
