@controllerpublic class useraction { @autowired private userloginservice userloginservice; @requestmapping("/login.do") public string userlogin(httpservletrequest request, string username, string password) throws exception { // 如果登陆失败从request中获取异常信息，shirologinfailure就是shiro异常类的全限定名 string exceptionclassname = (string) request.getattribute("shirologinfailure"); if (exceptionclassname != null) { if (unknownaccountexception.class.getname().equals(exceptionclassname)) { // 最终会抛给异常处理器 throw new xxxexception("用户名不存在"); } else if (incorrectcredentialsexception.class.getname().equals(exceptionclassname)) { throw new xxxexception("用户名/密码错误"); } else { throw new exception();// 最终在异常处理器生成未知错误 } } // 如果登录成功的话不走此方法，shiro认证成功会自动跳转到上一个请求路径，配的的successurl没效果，后边会说 // 登陆失败走此方法，捕获异常，然后 return ~ ,还到login页面 return "login.jsp"; }} |
3、检测权限 controller

//此方法为了验证权限是否生效@requestmapping("/findall.do")@requirespermissions("admin:ee")public modelandview list(httpservletrequest request){ ....... } |
三、常见问题
因为有一些特别常见的问题，需要修改xml配置，所以现在先手问题，把xml配置放在后边，直接就配置完善好的xml
问题一：登陆成功后shiro默认跳到上一次请求，没有上一次请求默认跳到/ ，那我们就想控制调到自己定义的路径咋办呢？
解决方案：
步骤一：继承formauthenticationfilter类，重写onloginsuccess方法，这里可以自定义路径，因为这里自定义了成功跳转的路径，所以配置里的successurl不用配置，赔了也没效果。。

public class loginsuccesstofilter extends formauthenticationfilter { @override protected boolean onloginsuccess(authenticationtoken token, subject subject, servletrequest request, servletresponse response) throws exception { webutils.getandclearsavedrequest(request); webutils.redirecttosavedrequest(request,response,"/findall.do"); return false; }} |
步骤二：
在shiro的xml配置文件中配置
|

|
<bean id="myfilter" class="com.xxx.realm.loginsuccesstofilter"></bean> |
在 shirofilter配置中引入,完整xml在后边
