登录拦截

用户认证

UserRealm
/*** realm充当了Shiro和应用程序数据之间桥梁，* 当我们进行认证和授权时，哪些用户可以登录，有什么角色，角色又有什么权限都是通过realm知晓的，所以应该至少有一个realm*/
//自定义realm
public class UserRealm extends AuthorizingRealm {//授权处理@Overrideprotected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {//调用hasRole()/isPermit()时触发System.out.println("--->授权enter Authorization");return null;}//认证处理@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {//调用SecurityUtils.getSubject() subject.login(token)时触发System.out.println("--->认证enter Authentication");String username = "root";String password = "123";//可以从authenticationToken中获取MyController中的token中的值UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;//认证用户名if (!token.getUsername().equals(username)) {return null;//此处返回的null会触发UnknownAccountException}//认证密码，认证失败会触发IncorrectCredentialsException//用户名–此处传的是用户对象 密码—从数据库中获取的密码 当前的realm名return new SimpleAuthenticationInfo("", password, "");//会和token中的password进行匹配，匹配上了就通过，匹配不上就报异常}
