"the request was rejected because its size " Spring, tomcat

Question

I'm trying to make a simple upload app with springboot and it works fine until i try to upload 10Mb+ files, i receive this message on my screen:

There was an unexpected error (type=Internal Server Error, status=500).
Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (14326061) exceeds the configured maximum (10485760)

I've done some research, and nothing have worked until now. I'll leave here below the things i've tried so far.

put this code(In various ways) in my "application.yml"

multipart: 
 maxFileSize: 51200KB
 maxRequestFile: 51200KB  

I've also tried this in my principal class:

    @Bean
public TomcatEmbeddedServletContainerFactory containerFactory() {
    TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
     factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
        @Override
        public void customize(Connector connector) {
         ((AbstractHttp11Protocol<?>) connector.getProtocolHandler()).setMaxSwallowSize(-1);
        }
     });
     return factory;
}

And some strange thing. If i enter in my tomcat web.xml, the multipart-config is:

<multipart-config>
      <!-- 50MB max -->
      <max-file-size>52428800</max-file-size>
      <max-request-size>52428800</max-request-size>
      <file-size-threshold>0</file-size-threshold>
    </multipart-config>

So where the hell this "...configured maximum (10485760)" is coming from ? (Sidenote: I'm using netbeans 8.1 and springboot 1.5).

Thx guys.(And sorry for the english s2)

Since asked, this is my application.yml

Answer 1

spring:
  http:
    multipart:
      enabled: true
      max-file-size: 50MB
      max-request-size: 50MB

or

spring.http.multipart.max-file-size=50MB
spring.http.multipart.max-request-size=50MB

Reference here

Hope it will works
