在spring boot gradle中上传大文件时出错

Question

How to upload large files in spring boot gradle?

@Bean
public CommonsMultipartResolver commonsMultipartResolver() {
    final CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setMaxUploadSize(-1);
    return commonsMultipartResolver;
}

@Bean
public FilterRegistrationBean multipartFilterRegistrationBean() {
    final MultipartFilter multipartFilter = new MultipartFilter();
    final FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(multipartFilter);
    filterRegistrationBean.addInitParameter("multipartResolverBeanName", "commonsMultipartResolver");
    return filterRegistrationBean;
}

When I gave above code then upload only large files. Not upload byte and kb files.

Answer 1

You can configure multipart maxFileSize in your application.yml or properties easily.

  multipart:
     maxFileSize: 30MB

Answer 2

There a 2 properties you can set:

multipart.max-file-size=1Mb

Max file size. Values can use the suffixed "MB" or "KB" to indicate a Megabyte or Kilobyte size.

multipart.max-request-size=10Mb

Max request size. Values can use the suffixed "MB" or "KB" to indicate a Megabyte or Kilobyte size.

You can find the list of all properties at http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html
