Spring Boot - BeanCreationException:Error creating bean with name 'uploadController' - spring

Question

I'm doing an application to convert a video to .gif.
The main question is that I try solve the "MaxUploadSizeExceededException", so I added the following properties in applicaiton.properties file:
spring.http.multipart.location=${java.io.tmpdir}
spring.http.multipart.max-file-size=50MB
spring.http.multipart.max-request-size=50MB
I got exception like this:

But when I use Spring 1.3.0.RELEASE and use the following application.properties, it works just fine:
multipart.location=${java.io.tmpdir}
multipart.max-file-size=50MB
multipart.max-request-size=50MB
The main difference is the application.properties file but I have no idea why it didn't work.
I'm new to Spring framework and it took me almost a whole day to solve this. Any suggestions or ideas are greatly appreciated!
Here's my code:
JustGifItApplication:
package app.justgifit
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class JustGifItApplication {
public static void main(String[] args) {
SpringApplication.run(JustGifItApplication.class, args);
}
}
UploadController:
package app.justgifit.controller;
import java.io.File;
import java.io.IOException;
import java.lang.invoke.MethodHandles;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RequestPart;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
#RestController
public class UploadController {
private final static Logger log = LoggerFactory.getLogger(MethodHandles.lookup().lookupClass());
#Value("${multipart.location}")
private String location;
#RequestMapping(value = "/upload", method = RequestMethod.POST, produces = MediaType.IMAGE_GIF_VALUE)
public String upload(#RequestPart("file") MultipartFile file,
#RequestParam("start") int start,
#RequestParam("end") int end,
#RequestParam("speed") int speed,
#RequestParam("repeat") boolean repeat) throws IOException{
File videoFile = new File(location + "/" + System.currentTimeMillis() + ".mp4");
file.transferTo(videoFile);
log.info("Saved file to {}", videoFile.getAbsolutePath());
return "";
}
}
application.properties
spring.http.multipart.location=${java.io.tmpdir}
spring.http.multipart.max-file-size=50MB

Answer 1

How about changing your code to this?
#Value("${spring.http.multipart.location}")
private String location;
Why do you think Spring can magically find a property with the key multipart.location when you've declared it as spring.http.multipart.location in your .properties file?
