springboot上传文件大小配置过程

@Configuration
public class TomcatConfig {
    @Value("1024KB")
    private String MaxFileSize;
    @Value("20MB")
    private String MaxRequestSize;
    @Bean
    public MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        //  单个数据大小
        factory.setMaxFileSize(MaxFileSize); // KB,MB
        // 总上传数据大小
        factory.setMaxRequestSize(MaxRequestSize);
        return factory.createMultipartConfig();
    }
}

 @Configuration
 @SpringBootApplication
 public class Application {
     public static void main(String[] args) throws Exception {
            SpringApplication.run(Application.class, args);
      }
     /**

      * @return
      */
     @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();
          }
