SpringBoot - MySql (WSL) integration - java

I've got certain problem with SpringBoot configuration using mysql service in WSL2.
I use
spring.jpa.hibernate.ddl-auto=update
When I start the application first time, then everything works fine, connection is established, database is updated, app is running. But when I restart app, it does not detect mysql connection anymore (but inside wsl terminal mysql service is still running).
I've got following logs:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

It seems like SpringBoot does not see mysql server anymore. But why though?
To fix that i need to restart whole WSL and then again everything works fine for the first time.
My application.properties file:
spring.datasource.url=jdbc:mysql://localhost:3306/gielda-db
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=update
spring.datasource.tomcat.connection-properties=useUnicode=true;characterEncoding=utf-8;
I tried to add or delete
spring.jpa.hibernate.ddl-auto=update
but with no effect
Edit: I tried to connect to the database through Mysql Workbench. Connection is successfully established and works fine so far.
I suppose it is something related to SpringBoot that causes connection loss?
Edit: I store whole SpringBoot application in wsl home directory. App and mysql-server running in WSL, there is no containerization.
When I created database in docker container and connected it to the app, then everything works fine. But I don't want to use docker. I want to have stable mysql-server on my WSL2 side. WSL distro: Ubuntu 20.04
Edit:
When i set spring.jpa.properties.hibernate.dialect nothing happens, but I noticed that once in a while different Exceptions are thrown, and then my whole mysql service in WSL stops. And again I have to restart whole WSL to be able to connect again to db. Different Exceptions are following:
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

You cannot leave the dialect empty
spring.jpa.properties.hibernate.dialect= //Your dialect


Unfortunately there is a lot going here. Between WSL internal way of exposing to localhost/127.0.0.1, JPA's interpretation of adresses, or maybe MySQL bugs.
The wierdest thing being that it works on first time but not on reboot of the Java app.
Anyway, I invite you to read these and the firsts 3-4 answers:
Solving a "communications link failure" with JDBC and MySQL
org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
Also try to activate debug on everything (and print sql statement) in your application.
An MVP would be great, but with WSL supposed culprit, this is gonna be difficult. Try to set your environnement outside of it or use a real Linux OS.

Spring boot application aws connection fail

I have a spring boot app that runs on my local server using MySQL8. It works perfectly on my localhost. I want to build the jar file to deploy the application on AWS. However, the maven build fails during installation because while maven testing the app, connection failure occurs. When I run the application it fails, too. This confirmed that the maven build cannot test the application, that's why it could create a jar file for me. Anyway, the problem is that.
I set the application available to the public while setting up the database but still getting the same issue.
Edit: I am currently located in Turkey. The server availability zone is "eu-south-1a". I don't know if I can connect to the server from Turkey. Maybe the problem is that.
The error is
com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

The security group should look like this for MySQL connection.

java.sql.SQLException: Access denied for user 'root'#'localhost' without any info about "Using password"

I'm trying to connect my spring app with mysql db that is at the same server as app.
When i'm start my app i catch error "java.sql.SQLException: Access denied for user 'root'#'localhost'"
I found many solutions about "java.sql.SQLException: Access denied for user 'root'#'localhost' (using password: YES)" and "java.sql.SQLException: Access denied for user 'root'#'localhost' (using password: NO)" but in my case where isn't any info about "Using password" in logs.
I found about "Using password" this:
① (using password: YES): The user name is not obtained
② (using password: NO): the password is not obtained
What mean my error?
My root user has all privileges and i can connect to db using it from command line.
My pom.xml:
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/web_blog_db
spring.datasource.username=root
spring.datasource.password=*mypass*
spring.jpa.show-sql=true
server.error.whitelabel.enabled=false
log:
java.sql.SQLException: Access denied for user 'root'#'localhost'

Is there any way for solving the known problem in Spring Boot when connection to a MySQL database with middle-european time zone?

In Spring Boot, when connecting to a Database from MySQL, i get the following Error:
2021-02-11 20:50:56.204 ERROR 22892 --- [ main] com.zaxxer.hikari.pool.HikariPool : HikariPool-1 - Exception during pool initialization.
java.sql.SQLException: The server time zone value 'Mitteleurop�ische Zeit' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specific time zone value if you want to utilize time zone support.

Well, the error occurs, because I live in the european timezome, and it seems like, that there is a not supported character inside the name of this one. Is there any way for changing it? Or maybe any solution, so that I can still be in my actual timezone?

I think there are two solutions:
set timezone for connection: in connection url set wanted timezone (like this jdbc:mysql://localhost:64356/test?serverTimezone=UTC)
fix timezone in mysql config SET GLOBAL time_zone = 'UTC';
I preferer to always use UTC timezone between database and application.

In my case it works using jdbc:mysql://localhost:3306/test?useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=Europe/Berlin
But it depends on your OS. This solution applies to Ubuntu.

Problem solved:
I just entered in the MySQL-Terminal the following Query:
SELECT NOW();
SET GLOBAL time_zone = '-6:00';
This changes the time zone from System to user-defined.
