I am using Spring Boot to test a upload functionality, and getting 'Required MultipartFile parameter 'file' is not present' error. Following are the 1) JSP, 2) Controller 3) Config Class 4) embedded tomcat log.

I figured out that there is an issue with the MultipartAutoConfiguration within spring boot. I disabled it and added @Bean in the web config and it worked. Based on the exception I saw that the Jackson Mapper was trying to resolve the multipart content instead of the multipart resolver itself.
Here is the snippet.
@EnableAutoConfiguration(exclude={MultipartAutoConfiguration.class}
Add the following in your webconfig class
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
logger.info("Loading the multipart resolver");
CommonsMultipartResolver multipartResolver
= new CommonsMultipartResolver();
return multipartResolver;
}
