多部分文件的最大尺寸異常 - 春季啓動embbeded tomcat的

Question

我已經設置最大文件大小

multipart.maxFileSize: 1mb 
multipart.maxRequestSize: 1mb 

這是我的控制器：

@RequestMapping(method=RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.MULTIPART_FORM_DATA_VALUE) 
@ResponseStatus(HttpStatus.CREATED) 
@Secured(Privileges.CAN_USER_READ) 
public void create(@RequestParam("file")final MultipartFile file,Principal principal) throws IllegalStateException, IOException,MultipartException{ 

    medicalHistoryService.create(new MedicalHistory(file)); 
} 

這是錯誤信息

2016-03-03 13:48:24.560 WARN 4992 --- [nio-8080-exec-1] h.c.w.RestResponseEntityExceptionHandler : Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (9288401) exceeds the configured maximum (1048576) 

2016-03-03 13:48:25.545 WARN 4992 --- [nio-8080-exec-2] h.c.w.RestResponseEntityExceptionHandler : Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (9288401) exceeds the configured maximum (1048576) 

超大文件請求後的最終結果是問題加載頁面。我沒有得到任何其他錯誤的堆棧跟蹤，所以我有點卡住了實際發生的事情。噢，我已經嘗試了許多其他解決方案，例如註冊過濾器，在ErrorController中處理異常。每次我都會得到相同的結果 - 服務器崩潰。

EDIT 2

我的異常處理類：

@ControllerAdvice 
public class RestResponseEntityExceptionHandler extends 
ResponseEntityExceptionHandler{ 

// 413 MultipartException - file size too big 
@ExceptionHandler({MultipartException.class,FileSizeLimitExceededException.class,java.lang.IllegalStateException.class}) 
public ResponseEntity<Object> handleSizeExceededException(final WebRequest request, final MultipartException ex) { 
    //log.warn("413 Status Code. File size too large {}", ex.getMessage()); 
    log.warn(ex.getMessage()); 
    final ApiError apiError = message(HttpStatus.PAYLOAD_TOO_LARGE, ex); 
    return handleExceptionInternal(ex, apiError, new HttpHeaders(), HttpStatus.PAYLOAD_TOO_LARGE, request); 
} 

}

Answer 1

這是棘手。 Tomcat屬性MaxSwallowSize導致了這個問題。顯然它是在最近的Tomcat版本中引入的。它背後的全部想法是，如果Tomcat意識到請求將被拒絕，終止高於默認2mb的連接（至少這是我的解釋）。簡單的覆蓋這個屬性修復了一些東西。我意識到這不是完美的解決方案，但它比僅僅終止連接好得多。

@Bean 
public TomcatEmbeddedServletContainerFactory containerFactory() { 
    TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory(); 
    factory.addConnectorCustomizers(new TomcatConnectorCustomizer() { 
     @Override 
     public void customize(Connector connector) { 
     ((AbstractHttp11Protocol<?>) connector.getProtocolHandler()).setMaxSwallowSize(-1); 
     } 
    }); 
    return factory; 
} 

Answer 2

屬性想：
spring.http.multipart.max-file-size=128KB
spring.http.multipart.max-request-size=128KB

見spring boot guides

Answer 3

我寫application.yml一些行來解決這個問題，如：

spring: 
    http: 
     multipart: 
      max-file-size: 10MB 
      max-request-size: 10MB 

它幫助而我在appl寫道ication.properties但不在yml中。
