如何使用Spring MVC处理MaxUploadSizeExceededException

如何解决如何使用Spring MVC处理MaxUploadSizeExceededException

上传最大大小的文件时出现一些错误。 因此，我正在尝试通过这种方式解决这些问题。我做了fileSizeError.jsp

-applicationContext

<bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize">
            <value>15728640</value>    
        </property>
</bean>
    
<bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
    <property name="exceptionMappings">
        <props>
            <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">/error/fileSizeError</prop>
        </props>
    </property>
    </bean>

-FileController

@PostMapping("/insertFile")
    String insertFile(@ModelAttribute("file")@Valid FileVO file,BindingResult result,@RequestParam("uploadfile")MultipartFile uploadfile,RedirectAttributes redirectAttrs) throws UnsupportedEncodingException{
        
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();

        String fileTitle = new String(file.getFileTitle().getBytes("8859_1"),"utf-8");
        String fileContent = new String(file.getFileContent().getBytes("8859_1"),"utf-8");
        
        if(result.hasErrors()) {
            return "/study/file/insertFile";
        }
        
        try {
            
            if(uploadfile !=null && !uploadfile.isEmpty()) {
                
                file.setFileTitle(fileTitle);
                file.setFileContent(fileContent);
                file.setFileSize(uploadfile.getSize());
                file.setFileName(uploadfile.getOriginalFilename());
                file.setFileContentType(uploadfile.getContentType());
                file.setFileData(uploadfile.getBytes());
                file.setUserId(auth.getName());
                fileService.uploadFile(file);
            }
        }catch(IOException e) {
            redirectAttrs.addFlashAttribute("message",e.getMessage());
        }
        return "redirect:/file/fileList/"+file.getBoardNum();
    }

但错误尚未修复。

我认为，如果添加属性“ exceptionMappings”，则将处理异常并转到jsp页面“ fileSizeError”。我真的不知道该如何解决。 我错过了什么吗？
