我正在使用Spring MVC @ControllerAdvice并@ExceptionHandler处理REST Api的所有异常。对于Web MVC控制器抛出的异常,它工作正常,但对于Spring Security自定义过滤器抛出的异常,它不工作,因为它们在调用控制器方法之前运行。
@ControllerAdvice
@ExceptionHandler
我有一个自定义的spring安全过滤器,它执行基于令牌的身份验证:
public class AegisAuthenticationFilter extends GenericFilterBean { ... public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { try { ... } catch(AuthenticationException authenticationException) { SecurityContextHolder.clearContext(); authenticationEntryPoint.commence(request, response, authenticationException); } } }
使用此自定义入口点:
@Component("restAuthenticationEntryPoint") public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint{ public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authenticationException) throws IOException, ServletException { response.sendError(HttpServletResponse.SC_UNAUTHORIZED, authenticationException.getMessage()); } }
并使用此类来全局处理异常:
@ControllerAdvice public class RestEntityResponseExceptionHandler extends ResponseEntityExceptionHandler { @ExceptionHandler({ InvalidTokenException.class, AuthenticationException.class }) @ResponseStatus(value = HttpStatus.UNAUTHORIZED) @ResponseBody public RestError handleAuthenticationException(Exception ex) { int errorCode = AegisErrorCode.GenericAuthenticationError; if(ex instanceof AegisException) { errorCode = ((AegisException)ex).getCode(); } RestError re = new RestError( HttpStatus.UNAUTHORIZED, errorCode, "...", ex.getMessage()); return re; } }
我需要做的是返回一个详细的JSON主体,即使对于spring security AuthenticationException也是如此。有没有办法使Spring Security AuthenticationEntryPoint和Spring MVC @ExceptionHandler一起工作?
我正在使用Spring Security 3.1.4和Spring MVC 3.2.4。
我尝试按照建议从AuthenticationEntryPoint自己编写json,它可以工作。
仅出于测试目的,我通过删除response.sendError更改了AutenticationEntryPoint
@Component("restAuthenticationEntryPoint") public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint{ public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authenticationException) throws IOException, ServletException { response.setContentType("application/json"); response.setStatus(HttpServletResponse.SC_UNAUTHORIZED); response.getOutputStream().println("{ \"error\": \"" + authenticationException.getMessage() + "\" }"); } }
这样,即使您使用的是Spring Security AuthenticationEntryPoint,也可以将自定义json数据与未经授权的401一起发送。
显然,您不会像我出于测试目的那样构建json,但会序列化一些类实例。
