Spring Boot： ClassNotFoundException when configure maxUploadSize of CommonMultipartResolver

file-upload java tomcat spring spring-boot
2022-09-04 23:46:45

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)

每次我尝试上传一个更大的文件时，都会抛出一个FileSizeLimitExceedException：

我尝试过但不起作用的事情：

设置雄猫属性

由于我的Web应用程序在Tomcat上运行（不是嵌入式应用程序，而是单独的外部应用程序），因此我尝试通过更改Tomcat配置来配置大小，如此处所述。不幸的是，这不起作用，因为最大上传大小仍保持在1 MB。

通过注释配置 Spring 的 CommonMultipartResolver

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

@Configuration 
public class CoreConfig {

    @Bean
    public CommonsMultipartResolver commonsMultipartResolver() {
    CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
    multipartResolver.setMaxUploadSize(50 * 1024 * 1024);
    return multipartResolver;
    }

}

但是当我启动Tomcat时，会引发以下异常：

通过 XML 进行配置

我没有使用注释驱动的配置，而是尝试了类似于此帖子的XML配置，但是我得到了与上面相同的ClassNotFoundException。

答案 1

你正在让它变得复杂。

只需添加到您的文件中，就是这样。无需使用 xml 或显式定义 .spring.http.multipart.maxFileSizeapplication.propertiesMultipartResolver

spring.http.multipart.maxFileSize=10MB

这在《Spring Boot 参考指南》中有关文件上传的部分中进行了说明。

对于所有属性，请检查多部分属性类。支持的其他属性包括 、 和 。spring.http.multipart.locationspring.http.multipart.maxRequestSizespring.http.multipart.fileSizeThreshold

这是因为Spring Boot使用默认的Servlet 3.0支持文件上传而不是commons-fileupload。因此，如果要使用它，则必须显式添加它的依赖项。当然，在这种情况下，属性不再起作用。ClassNotFoundExceptionspring.http.multipart.*


答案 2
@Bean
MultipartConfigElement multipartConfigElement() {
    MultipartConfigFactory factory = new MultipartConfigFactory();
    factory.setMaxFileSize("5120MB");
    factory.setMaxRequestSize("5120MB");
    return factory.createMultipartConfig();
}

尝试在定义 Bean 的类中添加此内容。
