Tomcat 8 - Maximum File Size

I use Spring-boot tomcat in my project.

I have multipart file upload and the limit is set as follows.

@Bean
    MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        factory.setMaxFileSize("1MB");
        factory.setMaxRequestSize("1MB");
        return factory.createMultipartConfig();
    }

But, if user is trying to load a file of more than 1 MB, it is throwing some exception.

led; nested exception is org.springframework.web.multipart.MultipartException: 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 (4719402) exceeds the configured maximum (1048576)] with root cause

You do something like this:

catch (Exception e) {
    redirectAttributes.addFlashAttribute("message",
            "You failed to upload, because file size too big " + name + " => " + e.getMessage());
}

Catch exception, then push a flash message to user's browser: redirectAttributes.addFlashAttribute()

This is offical tutorial for handling your uploading process (in Spring): https://spring.io/guides/gs/uploading-files/

I am not sure, but i think you can handle this exception using error page:

 // in web.xml
 <error-page>
    <error-code>413</error-code>
    <location>/ErrorHandlerServlet</location>
 </error-page>
 ... handlers for other http codes ...

413 - http code for "Request Entity Too Large" error.

Declare ErrorHandlerServlet error page (e.g. create JSP with <%@ page page isErrorPage="true" %> directive) and handle 413:

Integer statusCode = (Integer) httpRequest.
        getAttribute("javax.servlet.error.status_code");
if (statusCode == 413) {
        // print message...
}
// handle another error...
