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.

Process finished with exit code 1
I delete some of my error messages because that is too long. Besides, in my java code, I used
try {
Class.forName("org.mysql.Driver");
String jdbcConnString = "jdbc:mysql://my_endpoint_in_aws_rds:3306/my_db_name";
String jdbcUser = "my_username";
String jdbcPassword="my_password";
myConnection = DriverManager.getConnection(jdbcConnString, jdbcUser, jdbcPassword);
}
I already set my AWS security group inbounds rules to accept all TCP and ICMP-IPv4, which includes my Public IP address, but it still has a communication link failure.
I can use workbench on my local to connect to my AWS RDS with the endpoint, username and password.
I have no idea what's the reason, I've tried several methods but still doesn't work.
Do I miss something?

You are using mysql. Add the dependency to your pom.xml or graddle.settings
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
Add the values to your application.properties file.
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.ddl-auto=update
spring.datasource.hikari.jdbc-url=ADD-TO-HERE-DATABASE-URL
spring.datasource.hikari.username=ADD-TO-HERE-DATABASE-USERNAME
spring.datasource.hikari.password=ADD-TO-HERE-DATABASE-PASSWORD
spring.datasource.hikari.driver-class-name=com.mysql.cj.jdbc.Driver
Then create a class for hikari config.
import com.zaxxer.hikari.HikariDataSource;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.sql.DataSource;
#Configuration
#ConfigurationProperties(prefix="spring.datasource.hikari")
public class HikariConfig extends com.zaxxer.hikari.HikariConfig {
#Bean
public DataSource dataSource() {
return new HikariDataSource(this);
}
}
And that's it. I've done a simple project before.You can see an example. click
Also look at these docs.

MySQL Kerberos authentication

I have a instance of MySql 8.0.16 hosted in AWS RDS environment.
I need to configure the MySql instance to authenticate against a Active Directory using Kerberos protocol. I followed all steps described in the AWS documentation here.
I have inserted an user using the SQL instruction below:
CREATE USER 'testuser#domain.com'#'%' IDENTIFIED WITH 'auth_pam';
UPDATE mysql.user SET ssl_type = 'any' WHERE ssl_type = '' AND PLUGIN = 'auth_pam' and USER = 'testuser#domain.com';`
FLUSH PRIVILEGES;
(username and domain names have been changed for privacy!)
The database instance was started without errors and I got the access thru the sql comand prompt and also with workbench. So far, everything perfect!
But here the problem started. The database will be accessed from a web application developd in Java-SpringBoot using the the ConectorJ provided by MySql team. I configured the datasource following the instructions present in the Spring documentation. I have changed only these lines:
spring.datasource.url=jdbc:mysql://database-server/testdb
spring.datasource.username=testuser#domain.com
spring.datasource.password=password #(domain password)
spring.jpa.database-platform=org.hibernate.dialect.MySQL8Dialect
But when the container is starting, this error message appears in the logs:
2020-07-17 00:06:58.531 INFO 8016 --- [ task-1] com.zaxxer.hikari.HikariDataSource : HikariPool-1 - Starting...

Thank you in advance!

Hello to use PAM authentication you must use SSL to connect :
6.10 Connecting Using PAM Authentication
Java applications using Connector/J can connect to MySQL servers that use the pluggable authentication module (PAM) authentication scheme.
For PAM authentication to work, you must have the following:
A MySQL server that supports PAM authentication. See PAM Pluggable Authentication for more information. Connector/J implements the same cleartext authentication method as in Client-Side Cleartext Pluggable Authentication.
SSL capability, as explained in Section 6.7, “Connecting Securely Using SSL”. Because the PAM authentication scheme sends the original password to the server, the connection to the server must be encrypted.
PAM authentication support is enabled by default in Connector/J 8.0, so no extra configuration is needed.
To disable the PAM authentication feature, specify mysql_clear_password (the method) or com.mysql.cj.protocol.a.authentication.MysqlClearPasswordPlugin (the class name) in the comma-separated list of arguments for the disabledAuthenticationPlugins connection option. See Section 6.3, “Configuration Properties” for details about that connection option.
I think you must use something like this :
jdbc:mysql://127.0.0.1:3306/MySampleDb?verifyServerCertificate=true&useSSL=true&requireSSL=true
And pass truststore and keystore parameters
-Djavax.net.ssl.keyStore=path_to_keystore_file
-Djavax.net.ssl.keyStorePassword=password
-Djavax.net.ssl.trustStore=path_to_truststore_file
-Djavax.net.ssl.trustStorePassword=password

Update:
public DataSource getDataSource() {
DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create();
dataSourceBuilder.driverClassName("org.mariadb.jdbc.Driver");
dataSourceBuilder.url("jdbc:mariadb://localhost:6033/audit");
dataSourceBuilder.username("root");
dataSourceBuilder.password("root");
return dataSourceBuilder.build();
}
Added application.properties:
spring.jpa.hibernate.ddl-auto=update
server.servlet.context-path=/api
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
logging.level.org.hibernate.type=TRACE
server.port=60026

Because of your exception message :
Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
It means you must to add the database dialect inside your Spring Boot application.properties file :
spring.jpa.database-platform=org.hibernate.dialect.MariaDB106Dialect
I think you have found it since 2 years :P
I added the response because some people are searching that stuff too.

Step 1:
sudo mysql
Step 2: check your password. It might be empty or have something different
SELECT user,authentication_string,plugin,host FROM mysql.user;
Step 3: Set password
ALTER USER 'suyash'#'localhost' IDENTIFIED WITH mysql_native_password BY 'suyash';
Step 4:
FLUSH PRIVILEGES;
Now, try starting the spring application.

Adding name and password like this worked
# Connection url for the database "photo_app"
spring.datasource.url = jdbc:mysql://localhost:3306/photo_app
# Username and password
spring.datasource.username = suyash
spring.datasource.password = suyash
# Show or not log for each sql query
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

You need to allow this user to be accessed from all the host.
Google out this settings for your mysql ui tool and change to the host to % for given user.

Okay so as per my experience there could be a range of problems
Check if you're using XAMPP or not. If you are, make sure that Apache and MySQL are both Turned on. If not you wont be able to gain access to your mysql db.
If thats all good. Check your config.ini file for mysql. See if your username and password match that of what you're feeding java.
If that is matching then it check your code again. Maybe your access is denied because of your database initialization

1)Check your mysql username and password again
2)Check is there exists database called photo_app if not create it
