413请求实体太大的春季靴子

Question

application.properties：

spring.application.name=pgm

# multipart config

# enable multipart uploads
spring.servlet.multipart.enabled=true
# max file-size
spring.servlet.multipart.max-file-size=50MB

logging.level.org.springframework.web=DEBUG
server.tomcat.max-swallow-size=50MB

主要应用程序文件：

package com.mono.pgm;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class PgmApplication
{
    public static void main(String[] args)
    {
        SpringApplication.run(PgmApplication.class, args);
    }
}

控制器：

package com.mono.pgm;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

@RestController
public class controller
{
    @Autowired
    private fileUploadhelper helper;

    @GetMapping("/")
    public String hi()
    {
        return "hi!";
    }

    @PostMapping("/upload-file")
    public ResponseEntity<String> uploadFile(@RequestParam("theoneofall") MultipartFile file)
    {
        for(int i=0; i<15;i++)System.out.print('-');
        System.out.println(' ');

        System.out.println(file.getOriginalFilename());
        System.out.println(file.getSize());
        System.out.println(file.getContentType());
        System.out.println(file.getName());

        // file upload code
        try {
            boolean f = helper.uploadFile(file);
            if(f)return ResponseEntity.ok("Successful! upload");
        }catch(Exception e){
            e.printStackTrace();
        }
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("Something went wrong");
    }

}

upload类：

package com.mono.pgm;

import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;

import java.io.FileOutputStream;
import java.io.InputStream;

@Component
public class fileUploadhelper
{
    public String uploadDir = "C:\\Users\\comma\\Desktop\\projects\\pgm\\src\\main\\resources\\static\\images";

    public boolean uploadFile(MultipartFile file)
    {
        boolean f = false;

        try{
            InputStream is = file.getInputStream();
            byte[] data = new byte[is.available()];
            is.read(data);

            FileOutputStream fos = new FileOutputStream(uploadDir + "\\" + file.getOriginalFilename());
            fos.write(data);
            fos.flush();
            fos.close();
            f=true;

            // Files.copy(file.getInputStream, Paths.get(uploadDir+"\\"+file.getOriginalName()),StandardCopyOption.ReplaceExisting);

        }catch(Exception e){
            e.printStackTrace();
        }
        return f;
    }
}

i我问了GPT，它告诉我，由于Tomcat中的最大尺寸限制，它可能已经发生了，我尝试过，但没有起作用。
