4、MyRealm.java------自定义的Realm类
package com.papio.realm; import org.apache.commons.lang3.builder.ReflectionToStringBuilder; import org.apache.commons.lang3.builder.ToStringStyle; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.AuthenticationInfo; import org.apache.shiro.authc.AuthenticationToken; import org.apache.shiro.authc.SimpleAuthenticationInfo; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.authz.SimpleAuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.session.Session; import org.apache.shiro.subject.PrincipalCollection; import org.apache.shiro.subject.Subject; /** * 自定义的指定Shiro验证用户登录的类 * @see 在本例中定义了2个用户:papio和big,papio具有admin角色和admin:manage权限,big不具有任何角色和权限 * @create * @author */ public class MyRealm extends AuthorizingRealm { /** * 为当前登录的Subject授予角色和权限 * @see 经测试:本例中该方法的调用时机为需授权资源被访问时 * @see 经测试:并且每次访问需授权资源时都会执行该方法中的逻辑,这表明本例中默认并未启用AuthorizationCache * @see 个人感觉若使用了Spring3.1开始提供的ConcurrentMapCache支持,则可灵活决定是否启用AuthorizationCache * @see 比如说这里从数据库获取权限信息时,先去访问Spring3.1提供的缓存,而不使用Shior提供的AuthorizationCache */ @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals){ //获取当前登录的用户名,等价于(String)principals.fromRealm(this.getName()).iterator().next() String currentUsername = (String)super.getAvailablePrincipal(principals); // ListroleList = new ArrayList // List(); permissionList = new ArrayList // //从数据库中获取当前登录用户的详细信息 // User user = userService.getByUsername(currentUsername); // if(null != user){ // //实体类User中包含有用户角色的实体类信息 // if(null!=user.getRoles() && user.getRoles().size()>0){ // //获取当前登录用户的角色 // for(Role role : user.getRoles()){ // roleList.add(role.getName()); // //实体类Role中包含有角色权限的实体类信息 // if(null!=role.getPermissions() && role.getPermissions().size()>0){ // //获取权限 // for(Permission pmss : role.getPermissions()){ // if(!StringUtils.isEmpty(pmss.getPermission())){ // permissionList.add(pmss.getPermission()); // } // } // } // } // } // }else{ // throw new AuthorizationException(); // } // //为当前用户设置角色和权限 // SimpleAuthorizationInfo simpleAuthorInfo = new SimpleAuthorizationInfo(); // simpleAuthorInfo.addRoles(roleList); // simpleAuthorInfo.addStringPermissions(permissionList); SimpleAuthorizationInfo simpleAuthorInfo = new SimpleAuthorizationInfo(); //实际中可能会像上面注释的那样从数据库取得 if(null!=currentUsername && "papio".equals(currentUsername)){ //添加一个角色,不是配置意义上的添加,而是证明该用户拥有admin角色 simpleAuthorInfo.addRole("admin"); //添加权限 simpleAuthorInfo.addStringPermission("admin:manage"); System.out.println("已为用户[papio]赋予了[admin]角色和[admin:manage]权限"); return simpleAuthorInfo; }else if(null!=currentUsername && "big".equals(currentUsername)){ System.out.println("当前用户[big]无授权"); return simpleAuthorInfo; } //若该方法什么都不做直接返回null的话,就会导致任何用户访问/admin/listUser.jsp时都会自动跳转到unauthorizedUrl指定的地址 //详见applicationContext.xml中的(); 的配置 return null; } /** * 验证当前登录的Subject * @see 经测试:本例中该方法的调用时机为LoginController.login()方法中执行Subject.login()时 */ @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException { //获取基于用户名和密码的令牌 //实际上这个authcToken是从LoginController里面currentUser.login(token)传过来的 //两个token的引用都是一样的,本例中是org.apache.shiro.authc.UsernamePasswordToken@33799a1e UsernamePasswordToken token = (UsernamePasswordToken)authcToken; System.out.println("验证当前Subject时获取到token为" + ReflectionToStringBuilder.toString(token, ToStringStyle.MULTI_LINE_STYLE)); // User user = userService.getByUsername(token.getUsername()); // if(null != user){ // AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), user.getNickname()); // this.setSession("currentUser", user); // return authcInfo; // }else{ // return null; // } //此处无需比对,比对的逻辑Shiro会做,我们只需返回一个和令牌相关的正确的验证信息 //说白了就是第一个参数填登录用户名,第二个参数填合法的登录密码(可以是从数据库中取到的,本例中为了演示就硬编码了) //这样一来,在随后的登录页面上就只有这里指定的用户和密码才能通过验证 if("papio".equals(token.getUsername())){ AuthenticationInfo authcInfo = new SimpleAuthenticationInfo("papio", "papio", this.getName()); this.setSession("currentUser", "papio"); return authcInfo; }else if("big".equals(token.getUsername())){ AuthenticationInfo authcInfo = new SimpleAuthenticationInfo("big", "big", this.getName()); this.setSession("currentUser", "big"); return authcInfo; } //没有返回登录用户名对应的SimpleAuthenticationInfo对象时,就会在LoginController中抛出UnknownAccountException异常 return null; } /** * 将一些数据放到ShiroSession中,以便于其它地方使用 * @see 比如Controller,使用时直接用HttpSession.getAttribute(key)就可以取到 */ private void setSession(Object key, Object value){ Subject currentUser = SecurityUtils.getSubject(); if(null != currentUser){ Session session = currentUser.getSession(); System.out.println("Session默认超时时间为[" + session.getTimeout() + "]毫秒"); if(null != session){ session.setAttribute(key, value); } } } }
5、LoginController.java------处理用户登录
package com.papio.controller; import java.awt.Color; import java.awt.image.BufferedImage; import java.io.IOException; import javax.imageio.ImageIO; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.commons.lang3.StringUtils; import org.apache.commons.lang3.builder.ReflectionToStringBuilder; import org.apache.commons.lang3.builder.ToStringStyle; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.ExcessiveAttemptsException; import org.apache.shiro.authc.IncorrectCredentialsException; import org.apache.shiro.authc.LockedAccountException; import org.apache.shiro.authc.UnknownAccountException; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.subject.Subject; import org.apache.shiro.web.util.WebUtils; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.view.InternalResourceViewResolver; /** * 本例中用到的jar文件如下 * @see aopalliance.jar * @see commons-lang3-3.1.jar * @see commons-logging-1.1.2.jar * @see log4j-1.2.17.jar * @see shiro-all-1.2.2.jar * @see slf4j-api-1.7.5.jar * @see slf4j-log4j12-1.7.5.jar * @see spring-aop-3.2.4.RELEASE.jar * @see spring-beans-3.2.4.RELEASE.jar * @see spring-context-3.2.4.RELEASE.jar * @see spring-core-3.2.4.RELEASE.jar * @see spring-expression-3.2.4.RELEASE.jar * @see spring-jdbc-3.2.4.RELEASE.jar * @see spring-oxm-3.2.4.RELEASE.jar * @see spring-tx-3.2.4.RELEASE.jar * @see spring-web-3.2.4.RELEASE.jar * @see spring-webmvc-3.2.4.RELEASE.jar * @create Sep 30, 2013 11:10:06 PM */ @Controller @RequestMapping("mydemo") public class LoginController { /** * 用户登录 */ @RequestMapping(value="/login", method=RequestMethod.POST) public String login(HttpServletRequest request){ String resultPageURL = InternalResourceViewResolver.FORWARD_URL_PREFIX + "/"; String username = request.getParameter("username"); String password = request.getParameter("password"); UsernamePasswordToken token = new UsernamePasswordToken(username, password); token.setRememberMe(true); System.out.println("为了验证登录用户而封装的token为" + ReflectionToStringBuilder.toString(token, ToStringStyle.MULTI_LINE_STYLE)); //获取当前的Subject Subject currentUser = SecurityUtils.getSubject(); try { //在调用了login方法后,SecurityManager会收到AuthenticationToken,并将其发送给已配置的Realm执行必须的认证检查 //每个Realm都能在必要时对提交的AuthenticationTokens作出反应 //所以这一步在调用login(token)方法时,它会走到MyRealm.doGetAuthenticationInfo()方法中,具体验证方式详见此方法 System.out.println("对用户[" + username + "]进行登录验证..验证开始"); currentUser.login(token); System.out.println("对用户[" + username + "]进行登录验证..验证通过"); resultPageURL = "main"; }catch(UnknownAccountException uae){ System.out.println("对用户[" + username + "]进行登录验证..验证未通过,未知账户"); request.setAttribute("message_login", "未知账户"); }catch(IncorrectCredentialsException ice){ System.out.println("对用户[" + username + "]进行登录验证..验证未通过,错误的凭证"); request.setAttribute("message_login", "密码不正确"); }catch(LockedAccountException lae){ System.out.println("对用户[" + username + "]进行登录验证..验证未通过,账户已锁定"); request.setAttribute("message_login", "账户已锁定"); }catch(ExcessiveAttemptsException eae){ System.out.println("对用户[" + username + "]进行登录验证..验证未通过,错误次数过多"); request.setAttribute("message_login", "用户名或密码错误次数过多"); }catch(AuthenticationException ae){ //通过处理Shiro的运行时AuthenticationException就可以控制用户登录失败或密码错误时的情景 System.out.println("对用户[" + username + "]进行登录验证..验证未通过,堆栈轨迹如下"); ae.printStackTrace(); request.setAttribute("message_login", "用户名或密码不正确"); } //验证是否登录成功 if(currentUser.isAuthenticated()){ System.out.println("用户[" + username + "]登录认证通过(这里可以进行一些认证通过后的一些系统参数初始化操作)"); }else{ token.clear(); } return resultPageURL; } /** * 用户登出 */ @RequestMapping("/logout") public String logout(HttpServletRequest request){ SecurityUtils.getSubject().logout(); return InternalResourceViewResolver.REDIRECT_URL_PREFIX + "/"; } }
6、UserController.java------处理普通用户访问
package com.papio.controller; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller @RequestMapping("mydemo") public class UserController { @RequestMapping(value="/getUserInfo") public String getUserInfo(HttpServletRequest request){ String currentUser = (String)request.getSession().getAttribute("currentUser"); System.out.println("当前登录的用户为[" + currentUser + "]"); request.setAttribute("currUser", currentUser); return "/user/info"; } }
