我有一个关于Spring Security级别上的异常的问题。
public class DelegateRequestMatchingFilter extends RequestHeaderAuthenticationFilter {
private RequestMatcher ignoredRequests;
public DelegateRequestMatchingFilter(RequestMatcher matcher) {
super();
super.setPrincipalRequestHeader("SM_USER");
this.ignoredRequests = matcher;
}
@Override
public void doFilter(ServletRequest req, ServletResponse resp,FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpReq = (HttpServletRequest) req;
if(ignoredRequests.matches(httpReq)) {
chain.doFilter(req,resp);
} else {
super.doFilter(req,resp,chain);//<-- throws exception
}
}
}
@ControllerAdvice
public class ExceptionResolver extends AbstractHandlerExceptionResolver{
@Override
protected ModelAndView doResolveException(HttpServletRequest request,
HttpServletResponse responce, Object handler, Exception exception) {
ModelAndView toReturn = new ModelAndView();
toReturn.setView(new MappingJackson2JsonView());
toReturn.addObject("message", exception.getMessage());
toReturn.addObject("exceptionClass", exception.getClass().getCanonicalName());
return toReturn;
}
@ExceptionHandler(PreAuthenticatedCredentialsNotFoundException.class)
public ResponseEntity<Result> handleBindException(PreAuthenticatedCredentialsNotFoundException e) {
Result result = new Result("the identification header is missing");
result.setException(PreAuthenticatedCredentialsNotFoundException.class);
ResponseEntity<Result> response = new ResponseEntity<Result>(result, HttpStatus.FORBIDDEN);
return response;
}
}
安全配置
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter{
private UserDetailsService userDetailsService;
private PreAuthenticatedAuthenticationProvider preAuthenticatedProvider;
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
Map<String, List<GrantedAuthority>> rolesAuthorities = getRolesWithAutorities();
userDetailsService = new CustomUserDetailsService(...);
UserDetailsByNameServiceWrapper<PreAuthenticatedAuthenticationToken> wrapper =
new UserDetailsByNameServiceWrapper<PreAuthenticatedAuthenticationToken>(userDetailsService);
preAuthenticatedProvider = new PreAuthenticatedAuthenticationProvider();
preAuthenticatedProvider.setPreAuthenticatedUserDetailsService(wrapper);
auth.authenticationProvider(preAuthenticatedProvider);
}
@Bean
public SmUserFailureHandler smUserFailureHandler(){
return new SmUserFailureHandler();
}
@Bean
public AccessDeniedHandler accessDeniedHandler(){
AccessDeniedHandlerImpl handler = new AccessDeniedHandlerImpl();
handler.setErrorPage("/errorPage/");
return handler;
}
public RequestHeaderAuthenticationFilter siteMinderFilter() throws Exception
{
RequestHeaderAuthenticationFilter siteMinderFilter = new DelegateRequestMatchingFilter(
new OrRequestMatcher(
new AntPathRequestMatcher("/uriToSkip/")));
siteMinderFilter.setPrincipalRequestHeader("SM_USER");
siteMinderFilter.setAuthenticationManager(authenticationManager());
return siteMinderFilter;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
//...
http.addFilter(siteMinderFilter());
ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry registry = http.authorizeRequests();
//adding methods...
http = registry.and();
http.csrf().disable();
http.headers().cacheControl().disable();
http
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.NEVER);
}
}
如果我根据答案更改代码,即使SM_USEr标头存在且正确,也会出现此异常

首先,您应该在ExceptionTranslationFilter
之后添加筛选器,此筛选器将在捕获AccessDeniedException
和AuthenticationException
时处理它们。
http.addFilterAfter(siteMinderFilter(), ExceptionTranslationFilter.class);
接下来,您需要注入AuthenticationEntryPoint
来处理AuthenticationException
,已经存在一些AuthenticationEntryPoint
,您可以使用它,如HttpStatusEntryPoint
、LoginurlAuthenticationEntryPoint
、...;
如果希望返回JSON响应,则需要实现自己的authenticationentrypoint
,例如:
public class ExampleAuthenticationEntryPoint implements AuthenticationEntryPoint {
private static final Logger logger = LoggerFactory.getLogger(ExampleAuthenticationEntryPoint.class);
@Override
public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException {
logger.error(authException.getMessage(), authException);
if (!response.isCommitted()) {
Map<String, Object> responseMsg = new HashMap<String, Object>();
responseMsg.put("message", authException.getMessage());
ObjectMapper mapper = new ObjectMapper();
try {
response.setContentType("application/json;charset=utf-8");
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
PrintWriter writer = response.getWriter();
writer.write(mapper.writeValueAsString(responseMsg));
writer.flush();
writer.close();
} catch (IOException e) {
// ignore
logger.error(e.getMessage(), e);
}
}
}
}
http.exceptionHandling().authenticationEntryPoint(myEntryPoint());
@Bean
AuthenticationEntryPoint myEntryPoint() {
return new ExampleAuthenticationEntryPoint();
}
/*
Or just return 401
AuthenticationEntryPoint myEntryPoint() {
return new HttpStatusEntryPoint(HttpStatus.UNAUTHORIZED);
}
*/
else if (exception instanceof AccessDeniedException) {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authenticationTrustResolver.isAnonymous(authentication) || authenticationTrustResolver.isRememberMe(authentication)) {
logger.debug(
"Access is denied (user is " + (authenticationTrustResolver.isAnonymous(authentication) ? "anonymous" : "not fully authenticated") + "); redirecting to authentication entry point",
exception);
sendStartAuthentication(
request,
response,
chain,
new InsufficientAuthenticationException(
"Full authentication is required to access this resource"));
}
else {
logger.debug(
"Access is denied (user is not anonymous); delegating to AccessDeniedHandler",
exception);
accessDeniedHandler.handle(request, response,
(AccessDeniedException) exception);
}
}
更新2
Authentication currentUser = SecurityContextHolder.getContext()
.getAuthentication();
if (currentUser == null) {
return true;
}
if (!checkForPrincipalChanges) {
return false;
}
if(!principalChanged(request, currentUser)) {
return false;
}
CheckForPrincipalChanges
的默认值是false
,所以现在如果启用Anon
筛选器,它将返回false并跳过RequestTheAderAuthenticationFilter
中的do authentication,所以只需尝试do disableAnon
筛选器。您需要学习Spring Security代码并通过调试对其进行研究。

问题内容: 我写了一个过滤器函数,它将根据您传递的参数返回数据。我希望控制器具有相同的功能。是否可以在控制器中重用过滤器功能? 到目前为止,这是我尝试过的: 问题答案: 将 $ filter 注入控制器 然后,无论您想在哪里使用该过滤器,都可以像这样使用它: 如果要将参数传递给该过滤器,请使用单独的括号进行处理: 您要过滤的数组在哪里,并且是用于过滤的对象。
void unregister_prefilter(string function_name) Use this to dynamically unregister a prefilter. 动态注销一个预过滤器(模板编译前执行)。

问题内容: 我的过滤器很少 在我的项目中,要获得良好的结果,我必须在控制器中进行此过滤,而不是在视图中 我知道基本的语法,但我不知道如何在控制器中制作过滤器链,因此一切都将如模板中的示例一样工作。 我找到了一些解决方案,现在仅使用一个过滤器,但是应该可以用于许多;) 我在ng-repeat中使用此功能可以正常工作,但是我必须使用少量过滤器进行检查。 问题答案: 您只需重新过滤您从第一个过滤器返回的
问题内容: 有谁知道如何编写一个servlet过滤器,该过滤器将在给定文件/内容类型的响应上设置缓存头?我有一个提供大量图像的应用程序,我想通过让浏览器缓存那些不经常更改的图像来减少托管它的带宽。理想情况下,我希望能够指定一种内容类型,并在内容类型匹配时让它设置适当的标题。 有人知道该怎么做吗?或者,甚至更好的是,他们愿意共享示例代码吗?谢谢! 问题答案: 在您的过滤器中有以下行: 响应包装如下所
