我正在使用Spring Boot 2.1.3 (使用标准的Tomcat嵌入式Web服务器)开发一个端点来上传图像,并且我想限制分段上传的大小。我可以通过以下属性轻松做到这一点:
spring:
servlet:
multipart:
max-file-size: 2MB
max-request-size: 2MB
但是我总是得到Spring无法捕获的500,因为是Tomcat引发了异常并且请求没有到达RestController中的代码。
2019-03-02 10:12:50.544 ERROR [] [ o.a.c.c.C.[.[.[/].[dispatcherServlet]] [] Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.multipart.MaxUploadSizeExceededException: Maximum upload size exceeded; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (3917946) exceeds the configured maximum (2097152)] with root cause
org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (3917946) exceeds the configured maximum (2097152)
我的ExceptionHandler就是这样,但是无论注解中包含什么异常,显然都行不通:
@ExceptionHandler(MaxUploadSizeExceededException.class)
public ResponseEntity handleMaxSizeException(Exception e) {
logger.warn(e.getMessage());
...
return status(HttpStatus.PAYLOAD_TOO_LARGE).body(...);
}
我已经使用已经提到的属性尝试了此操作,但是没有任何效果:
@Bean
public TomcatServletWebServerFactory containerFactory() {
TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
factory.addConnectorCustomizers((TomcatConnectorCustomizer) connector ->
((AbstractHttp11Protocol<?>) connector.getProtocolHandler()).setMaxSwallowSize(-1));
return factory;
}
我已经检查了以下问题(及其他问题)的答案,但它们大多已过时或根本无法使用:
有人在为此苦苦挣扎吗?

有点晚。您需要在application.properties或application.yml中进行设置
server.tomcat.max-swallow-size=-1
有了它,tomcat将不会干扰上传请求,并且该操作将在spring之前完全处理,并且异常控制器将正常运行。

请在您的application.properties
中添加它:
spring.servlet.multipart.max-file-size=50Mb
spring.servlet.multipart.max-request-size=50Mb
您可以在上述配置中根据需要更改大小
