Question

使用Jhipster和Spring + Mongo以及Gridfs来处理db中保存的文件。当我尝试上传大于1Mb的文件时，它会给我一个500错误：

java.io.IOException: UT000054: The maximum size 1048576 for an individual file in a multipart request was exceeded

尝试在application-dev.yml中设置此项但未成功：

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

如何更改此限制？

Answer 1

将此内容添加到WebConfigurer（如果存在）

@Bean

public MultipartConfigElement multipartConfigElement() {

     MultipartConfigFactory factory = new MultipartConfigFactory();

     factory.setMaxFileSize("100MB");

     factory.setMaxRequestSize("100MB");

     return factory.createMultipartConfig();

}

Answer 2

当JHipster使用下载时，一种解决方法是在多部分解析器bean中设置上传大小，如下所示：

@Configuration
public class UndertowConfiguration {

    @Value("${spring.http.multipart.max-file-size:10}")
    private long maxFileSize;

    @Bean(name = "multipartResolver")
    public MultipartResolver multipartResolver() {
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
        multipartResolver.setDefaultEncoding("utf-8");
        multipartResolver.setResolveLazily(true);
        multipartResolver.setMaxUploadSize(1024*1024*maxFileSize);
        multipartResolver.setMaxUploadSizePerFile(1024*1024*maxFileSize);
        return multipartResolver;
    }
}

Answer 3

您可以在application-dev.yml文件中配置这两个属性，而不是在application.properties中对其进行配置：

spring.http.multipart.max-file-size=10MB
spring.http.multipart.max-request-size=10MB

有关其他信息，您可以查看Spring Uploading file指南。

作为旁注，如果您稍后决定迁移到 spring-boot 2.0 ，则这些属性已从spring.http.multipart更改为spring.servlet.multipart。

Answer 4

试试这个，

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

对于spring boot2.x：

以及旧版本

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

要获得无限制的上传文件大小，请将设置设置为max-file-size：-1将使其具有无限的文件大小。
