An error is reported in file upload, and the interface breakpoint does not go because of the default limit of Tomcat

Spring Boot:The field file exceeds its maximum permitted size of 1048576 bytes.

The configuration file can be changed. I use YML configuration

spring:
  servlet:
    multipart:
      max-file-size: 50MB
      max-request-size: 100MB

Please like it and form good habits!

Please leave a message for questions, communication and encouragement!

The online method is not easy to use, as follows

Solution 1: Prompt for expired methods!!!

Add the following code to the startup class.

@Bean
public MultipartConfigElement multipartConfigElement() {
　　MultipartConfigFactory factory = new MultipartConfigFactory();
　　// single file maximum
　　factory.setMaxFileSize("10240KB"); // KB,MB
　　// Set the total upload data size
　　factory.setMaxRequestSize("102400KB");
　　return factory.createMultipartConfig();

}

Solution 2: red line burst, prompt too long

Depending on the version of spring boot, add different configurations to the application file

Spring Boot 1.3 or earlier, the configuration:

　　multipart.maxFileSize = 100Mb

multipart.maxRequestSize=150Mb

Spring Boot 1.4 or later, the configuration:

　　spring.http.multipart.maxFileSize = 100Mb
　　spring.http.multipart.maxRequestSize = 150Mb


Spring Boot 2.0 or later: Mb change to MB

spring.servlet.multipart.max-file-size = 100MB
spring.servlet.multipart.max-request-size = 150MB
