在Spring webapp中处理MaxUploadSizeExceededException

Question

我试图处理最大上传大小异常，但是我发现所有的解决方案都失败了，我尝试执行HandlerExceptionResolver,@ControllerAdvice和@ExceptionHandler(MaxUploadSizeExceededException.class)注解的方法，但没有提供帮助。 在类似问题的答案中，我发现它可能是因为控制器甚至被调用之前抛出异常，但我没有对这个问题的这种洞察力，所以我不能自己解决它。
堆栈跟踪：

和处理multipart解决等等...
SecurityWebAppInitializer.class我的代码的某些部分 - 我怀疑这MultipartFilter可能是问题的一部分，但它必须是有因为这http://docs.spring.io/spring-security/site/docs/3.2.0.CI-SNAPSHOT/reference/html/csrf.html#csrf-multipartfilter

@Order(1) 
public class SecurityWebAppInitializer extends AbstractSecurityWebApplicationInitializer { 

    @Override 
    protected void beforeSpringSecurityFilterChain(ServletContext servletContext) { 
     insertFilters(servletContext, new MultipartFilter()); 
    } 

} 

多部分配置

@Configuration 
public class MultipartConfig { 

    @Bean 
    public MultipartResolver filterMultipartResolver() { 
     CommonsMultipartResolver filterMultipartResolver = new CommonsMultipartResolver(); 
     filterMultipartResolver.setMaxUploadSize(500000); 

     return filterMultipartResolver; 
    }   
} 

的个

WebAppInitializer.class

@Order(2) 
public class WebAppInitializer extends 
     AbstractAnnotationConfigDispatcherServletInitializer { 

    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     return new Class<?>[] {MultipartConfig.class, SecurityConfig.class, PersistenceConfig.class }; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     return new Class<?>[] { DispatcherConfig.class }; 
    } 

    @Override 
    protected String[] getServletMappings() { 
     return new String[] { "/" }; 
    } 

    @Override 
    protected Filter[] getServletFilters() { 

     CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter(); 
     characterEncodingFilter.setEncoding("UTF-8"); 
     return new Filter[] { characterEncodingFilter}; 
    } 

} 

如果您需要Web应用程序的其他一些地方只问。 在此先感谢

Answer 1

如果您不知道最大上传大小，则不要设置最大上传大小。 如果你想限制最大上传大小，那么你需要考虑否则评论它 下面我已经评论了setter设置最大上传大小。

@Configuration 
public class MultipartConfig { 

    @Bean 
    public MultipartResolver filterMultipartResolver() { 
     CommonsMultipartResolver filterMultipartResolver = new CommonsMultipartResolver(); 
     //filterMultipartResolver.setMaxUploadSize(500000); 

     return filterMultipartResolver; 
    }   
} 

Answer 2

我抓住它由此类：

@Controller 
public class ExceptionHandlerController implements ErrorController, HandlerExceptionResolver{ 
private static final String PATH = "/error"; 

Logger log = LoggerFactory.getLogger(ExceptionHandlerController.class); 

public String getErrorPath() { 
    return PATH; 
} 

@Override 
public ModelAndView resolveException(HttpServletRequest arg0, 
HttpServletResponse arg1, Object arg2, Exception exception) { 
    log.debug("Captured...."); 
    Map<Object, Object> model = new HashMap<Object, Object>(); 
    //all the exception is here and u can specified it by this exception: MaxUploadSizeExceededException 
    return new ModelAndView("Error", (Map) model); 
} 
} 

我用SpringBoot，所以它需要我实现ErrorController。如果你不那么就不需要实现它。

希望它有助于寻找这种情况的人。
