After Spring boot server initialization, it throws InvocationTargetException and ApplicationContextException

I am new to spring and I am trying to implement a simple spring boot application that will parse a json string and write it to a file.

Here is the code of my main class

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

//@SpringBootApplication
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {

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


    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(applicationClass);
    }

    private static Class<Application> applicationClass = Application.class;
}

      

        
        
        
      

    

Stop controller definition below

package com.example;
import java.io.*;

import javax.servlet.http.HttpServletRequest;

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class Controller {

    @RequestMapping(path="/api",consumes=MediaType.APPLICATION_JSON_VALUE)
    public String insertData(@RequestBody String rawJsonData,HttpServletRequest request) throws ParseException, IOException{
        JSONParser jparser=new JSONParser();
        Object jsonObj=jparser.parse(rawJsonData);
        JSONObject jObject=(JSONObject)jsonObj;

        FileWriter filewriter=new FileWriter(new File("C:\\Users\\Desktop\\Aayushi.txt"));
        filewriter.write(jObject.toJSONString());
        return rawJsonData;

    }
}

If I run this code as "Run as-> Maven Build" then I get the following errors and I'm not sure why these errors are coming.

Updated error log:
