java Spring Boot：配置 CommonMultipartResolver 的 maxUploadSize 时出现 ClassNotFoundException

Question

提问by Jim Holden

I'm using Spring Boot for my web application and I'm trying to configure the maxUploadSize of Spring's CommonMultipartResolver. Currently, it seems to be limited by a Spring (?) default size of 1 MB. The upload is done through a REST interface, and the method signature looks like this:

我正在为我的 Web 应用程序使用 Spring Boot，并且我正在尝试配置 Spring 的 CommonMultipartResolver 的 maxUploadSize。目前，它似乎受到 Spring (?) 默认大小 1 MB 的限制。上传是通过 REST 接口完成的，方法签名如下所示：

@RequestMapping(value = "/upload", method = RequestMethod.POST)
public void uploadFile(@RequestParam("file") MultipartFile file, HttpServletRequest request)

Everytime I try to upload a bigger file, a FileSizeLimitExceededException is thrown:

每次我尝试上传更大的文件时，都会抛出 FileSizeLimitExceededException：

Things I have tried, but did not work:

我尝试过但没有奏效的事情：

Setting Tomcat properties

设置 Tomcat 属性

Since my web app is running on Tomcat (not the embedded one, but a separate external one), I tried configuring the size by changing the Tomcat configuration as is described here. Unfortunately, this has no effect, as the max upload size still remains at 1 MB.

由于我的web应用程序Tomcat上运行（不是嵌入，而是一个单独的外部之一），我试图通过中被描述为改变Tomcat配置配置大小这里。不幸的是，这没有效果，因为最大上传大小仍然保持在 1 MB。

Configuring Spring's CommonMultipartResolver by annotation

通过注解配置Spring的CommonMultipartResolver

Since the value of 1MB seems to come from the CommonMultipartResolver (I can see that the value of 1MB is set when debugging), I tried configuring Spring via annotation like this:

由于1MB的值似乎来自CommonMultipartResolver（可以看到调试时设置了1MB的值），我尝试通过这样的注解配置Spring：

Configuration via XML

通过 XML 配置

Instead of an annotation-driven configuration, I tried a configuration via XML similar to this posting, but I'm getting the same ClassNotFoundException as above.

我没有使用注释驱动的配置，而是尝试通过类似于这篇文章的XML 进行配置，但我得到了与上面相同的 ClassNotFoundException。

spring.http.multipart.maxFileSize=10MB

Answer 1

回答by M. Deinum

You are making it way to complex.

你正在使它变得复杂。

Just add spring.http.multipart.maxFileSizeto your application.propertiesfile and well that is it. No need to use xml or explicitly define a MultipartResolver.

只需添加spring.http.multipart.maxFileSize到您的application.properties文件中即可。无需使用 xml 或显式定义MultipartResolver.

@Bean
MultipartConfigElement multipartConfigElement() {
    MultipartConfigFactory factory = new MultipartConfigFactory();
    factory.setMaxFileSize("5120MB");
    factory.setMaxRequestSize("5120MB");
    return factory.createMultipartConfig();
}

This is explained in the section about file uploads in the Spring Boot Reference Guide.

这在Spring Boot 参考指南中有关文件上传的部分中进行了解释。

For all properties check the MultipartPropertiesclass. The other properties supported are spring.http.multipart.location, spring.http.multipart.maxRequestSizeand spring.http.multipart.fileSizeThreshold.

对于所有属性检查MultipartProperties类。支持的其他属性是spring.http.multipart.location,spring.http.multipart.maxRequestSize和spring.http.multipart.fileSizeThreshold。

The ClassNotFoundExceptionis due to the fact that Spring Boot uses the default Servlet 3.0 support for file uploads NOT commons-fileupload. So if you want to use that, you would have to explicitly add the dependency for it. And ofcourse the spring.http.multipart.*properties don't work anymore in that case.

这ClassNotFoundException是因为 Spring Boot 使用默认的 Servlet 3.0 支持文件上传而不是 commons-fileupload。所以如果你想使用它，你必须明确地为它添加依赖项。spring.http.multipart.*当然，在这种情况下，这些属性不再起作用。

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

Try adding this in the class where you are defining beans.

尝试在定义 bean 的类中添加它。

With spring-boot 1.5.3 you should use the following code in application.yml

使用 spring-boot 1.5.3 你应该在 application.yml 中使用以下代码

spring.servlet.multipart.max-file-size=30MB
spring.servlet.multipart.max-request-size=30MB

for Spring Boot 2.0+ use spring.servlet instead of spring.http
