Guys for 3 days I am searching for an answer and can't find the exact answer for my problem. So I am doing some tutorials on Spring and Hibernate and get stuck when trying to establish a connection between Spring Boot project, MySQL database and Tomcat server. Here is my "pom.xml" file:
<?xml version="1.0" encoding="UTF-8"?>

And here are my properties:
spring.thymeleaf.cache=false
# ===============================
# = DATA SOURCE
# ===============================
# Set here configurations for the database connection
spring.datasource.url=jdbc:mysql://localhost:3306/bookstoredatabase?autoReconnect=true&useSSL=false
# Username and secret
spring.datasource.username=root
spring.datasource.password=target
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
# ===============================
# = JPA / HIBERNATE
# ===============================
# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager).
# Show or not log for each sql query
spring.jpa.show-sql=true
# Hibernate ddl auto (create, create-drop, update): with "update" the database
# schema will be automatically updated accordingly to java entities found in
# the project
spring.jpa.hibernate.ddl-auto = update
# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
I am using Tomcat from XAMPP - version 7.0.56. MySQL Server and the connector are both version 8. Without using Tomcat, I am perfectly able to connect to any database, edit it, etc.
Here are the errors, which occur:
INFO 15816 --- [main] org.hibernate.Version: HHH000412: Hibernate Core {5.0.11.Final}
INFO 15816 --- [main] org.hibernate.cfg.Environment: HHH000206: hibernate.properties not found

ERROR 15816 --- [main] o.a.tomcat.jdbc.pool.ConnectionPool: Unable to create initial connections of pool. com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.
The full error log can be seen here . I have tried so many things. Please help me guys.
EDIT:
Okay. I have read the error log more carefully. I am using Tomcat from XAMPP, version 7.056, but Spring starts Tomcat with version 8. I don't know if I should make another question, but when I added <tomcat.version>7.0.56</tomcat.version> to my properties, the error log changed into this
