在启动类放下面的代码
@Bean
public MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
//文件最大
factory.setMaxFileSize( DataSize.ofBytes(1024 * 1024 * 3) ); //KB,MB
factory.setMaxRequestSize(DataSize.ofBytes(1024 * 1024 * 3));
return factory.createMultipartConfig();
}
