多部分文件最大大小异常-spring boot embbeded tomcat

Question

我已将最大文件大小设置为

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

这是我的控制器：

@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));
}

这是一条错误消息

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)

请求过大文件后的最终结果是加载页面问题。我没有得到任何其他错误的堆栈跟踪，所以我有点卡住了什么是实际发生的。哦，是的，我已经尝试了许多其他的解决方案，如注册过滤器，在错误控制器中处理异常。每次我都会以同样的结果服务器崩溃告终。

我的异常处理类：

@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

请在应用程序中添加以下行。spring启动版本-2.0.1的属性。释放

spring.servlet.multipart.max-file-size=128MB
spring.servlet.multipart.max-request-size=128MB
spring.servlet.multipart.enabled=true

这解决了我的问题。

Answer 2

这很棘手。Tomcat属性MaxSize导致了此问题。显然，它是在Tomcat的一个最新版本中引入的。其背后的整个想法是，如果Tomcat意识到请求将被拒绝，终止连接的速度将高于默认的2mb（至少这是我的解释）。简单地重写此属性可以解决问题。我意识到这不是完美的解决方案，但它比仅仅终止连接要好得多。

@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 3

从Spring Boot 2开始

spring。servlet。多部分。最大文件大小=128KB
spring。servlet。多部分。最大请求大小=128KB

看文档

Spring靴1。十、

属性应该是：
spring.http.multipart.max-file-size=128KB
spring.http.multipart.max-estest-size=128KB
