java – 处理Spring Security中的自定义异常
|
我们正在使用
Spring MVC
Spring安全性hibernate创建一个RESTful API.
认证可以以各种方式发生:BasicAuth,通过POST请求中的不同参数以及通过Web登录. 我们在自定义HandlerExceptionResolver中处理我们所有的spring异常.这对我们的控制器中抛出的所有异常都很好,但是我不知道如何处理自定义弹簧安全过滤器中抛出的自定义异常. 我在stackoverflow上发现了这个问题: 我们为什么需要这个? 可能的解决方案 另一种可能性:我们可以在spring安全性过滤器链中执行类似于ExceptionTranslationFilter的操作,并且执行类似于AccessDeniedHandler的操作: RequestDispatcher dispatcher = request.getRequestDispatcher(errorPage); dispatcher.forward(request,response); 我们可以在请求中添加一些参数(错误代码,原因等),并将其指向将处理JSON或HTML中的渲染的控制器. 这是我们的配置的一个简短的摘录: 春天安全: <http create-session="stateless" use-expressions="true" >
<!-- Try getting the authorization object from the request parameters. -->
<security:custom-filter ref="filter1" after="SECURITY_CONTEXT_FILTER"/>
<security:custom-filter ref="filter2" before="LOGOUT_FILTER"/>
<!-- Intercept certain URLS differently -->
<intercept-url pattern="/admin/**" access="hasRole('ROLE_ADMIN')" />
<!-- Some more stuff here -->
<intercept-url pattern="/**" access="denyAll" />
<http-basic />
</http>
HandlerExceptionResolver的AppConfig @Bean
public HandlerExceptionResolver handlerExceptionResolver(){
logger.info("creating handler exception resolver");
return new AllExceptionHandler();
}
我们的自定义HandlerExceptionResolver public class AllExceptionHandler implements HandlerExceptionResolver {
private static final Logger logger = LoggerFactory
.getLogger(AppConfig.class);
@Override
public ModelAndView resolveException(HttpServletRequest request,HttpServletResponse response,Object handler,Exception ex) {
// This is just a snipped of the real method code
return new ModelAndView("errorPage");
}
我们的一个过滤器的相关部分: try {
Authentication authResult = authenticationManger.authenticate(authRequest);
SecurityContextHolder.getContext().setAuthentication(authResult);
}
catch(AuthenticationException failed) {
SecurityContextHolder.clearContext();
throw failed;
}

有人有任何指示我们如何解决这个问题? 我们使用Spring Security 3.1.0和spring web mvc 3.1.0. 解决方法重要的是要记住,Spring Security中的过滤器的顺序是重要的.从Spring Security 3书:
如果您的过滤器是关于授权的,那么将默认授权过滤器使用的方法作为链条的末尾是一个很好的做法.这样你就不用重新发明了. 标准过滤器:Table in documentation 您正确配置过滤器链后,您可以配置错误页面,甚至自定义处理程序.更多信息,请参阅documentation. (编辑:安卓应用网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
