本文详细介绍了如何在Spring Boot应用中解决大文件上传时遇到的Maximum upload size exceeded错误。通过修改配置文件中的max-file-size和max-request-size参数，并创建一个自定义的配置类来调整文件上传的最大尺寸。

问题bug：

"Maximum upload size exceeded; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (37524618) exceeds the configured maximum (10485760)",

配置文件中加入：

spring： 
  servlet:
    multipart:
      max-file-size: 50MB
      max-request-size: 50MB

新增一个配置类


@Configuration
public class UploadConfig {


    @Value("${spring.servlet.multipart.max-file-size}")
    private String maxFileSize;
    @Value("${spring.servlet.multipart.max-request-size}")
    private String maxRequestSize;

    @Bean
    public MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        //单个文件最大
        //KB,MB
        factory.setMaxFileSize(maxFileSize); 
        /// 设置总上传数据总大小
        factory.setMaxRequestSize(maxRequestSize);
        return factory.createMultipartConfig();
    }
}
