ApplicationEventMulticaster not initialized error, need tip

I am trying to follow this tutorial from W3schools for SpringBoot.
This is how my project looks like:
I followed the tutorial and changed the pom.xml to what it shows in the above link. Then, I copied the App.java class from the tutorial and put it into DemoApplication.java. Lastly, the controller class was also copied into JDBCController.java.
DemoApplication.java:
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.support.SpringBootServletInitializer;
#SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
JDBCController.java:
package com.example.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class JDBCController {
#Autowired
JdbcTemplate jdbc;
#RequestMapping("/insert")
public String insertData(){
jdbc.execute("insert into users(seq,user_name)values(12,'hkumar')");
return"Data inserted Successfully";
}
}
When I run everything these are the errors I get:

I am a bit lost D:
I tried putting JDBCController.java with DemoApplication.java. Unfortunately it does not fix the issue :(

Remove the JDBCController.java from the "src/test/java" and move it to the "src/main/java" package.

I had the wrong JAVA version for the project...........

Build failing to include Jackson Json Parser

I tryed to change the version, but I got the same error. What can I try?
Otherwise which other Json Parser do you recommend me?

ToStringSerializerBaseis present in version 2.12 of jackson-databind
you should have to change version 2.9.9 to 2.12 . You can analyze the used library versions with the command mvn dependency:tree it must be crashing in your current scenario.
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>

Problem in running application with Vaadin and Spring (MySQL DB)

I am trying to connect a Vaadin project to a MySQL database following the instructions I found here: https://dzone.com/articles/how-to-connect-a-mysql-database-to-a-vaadin-applic
I downloaded the ready project in the article (also available here: https://github.com/Liskokuningas/databasemysqlexample)
I, then, created the dummy data schema in MySQL Workbench and tried to run the application via the Windows 10 Command line like this:
mvn clean install -U /*all is fine here, build is successful*/
and then mvn spring-boot:run
Then I get an error:
Followed by:

Though the build appears to be successful I cannot open the application in the
browser getting a 404 error:The requested resource [/] is not available.
Any ideas about that? Anyone can tell me how to connect a Vaadin to a MySQL database?
Thanks in advance!

In the stacktrace you can see the following advice
Found app shell configuration annotations in non `AppShellConfigurator` classes.
Please create a custom class implementing `AppShellConfigurator` and move the following annotations to it:
- #PWA from com.example.mysql.application.spring.MainView
So you have to create an AppShellConfigurator implementation and move #PWA annotation from MainView to that new class.
Here's the link to documentation: https://vaadin.com/docs/v20/flow/advanced/modifying-the-bootstrap-page/#customizing-the-application-shell-during-runtime

How to find if any jar is using a deprecated class

I was migrating from Spring boot 1.3 to 1.5 and am getting a class not found error for ServletRegistrationBean.
Which is expected as this has been deprecated.
What am not able to understand is which jar is causing this?
I would like to understand how can debug it further?
Basically how to walk through jars to see which class is getting loaded at the time of failure and where it is from so I can correct my dependencies
I have used couple of tools to walk through the jars and find dependencies but that did not help me

Most probably you simply left both versions on the classpath, APIs are getting mixed up. Double check your classpath for duplicated libraries
Also please reffer to this github issue https://github.com/spring-projects/spring-boot/issues/8186

Spring boot application Application startup failed

I'm trying to learn Spring Boot on my own by reading online tutorials. I must have been done something silly and got the error. To reproduce the error, I must give the whole project. Here is the GitHub link: https://github.com/madsum/Springboot
Could somebody kindly let me knowe what is wrong?
