org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field xxx exceeds its maximum permitted size of 1048576 bytes.
springboot 通过MultipartFile接受前端传过来的文件时是有文件大小限制的(springboot内置tomact的的文件传输默认为1MB),我们可以通过配置改变它的大小限制
首先在启动类中加入: @configuration
再在启动类中加上代码
@Bean
public MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
//文件最大
factory.setMaxFileSize("10240KB"); //KB,MB
/// 设置总上传数据总大小
factory.setMaxRequestSize("102400KB");
return factory.createMultipartConfig();
}
