The Spring boot app doesn't seem to run after putting it in container – Docker

I am trying to create docker containers and I was trying to 1 for MySql and another for Spring io. The DB container is running OK but the spring boot container comes at a point and exits. I have searched and tried many thing but I can’t seem to be able to solve it, the thing that I concluded that it seems that something is wrong with the database environment or aplication.properties or maybe it could be somewhere else. I would be so grateful if someone could guide me to the solution.

application.properties:

spring.datasource.url=jdbc:mysql://DB_containerfile:3306/phase2?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC
spring.datasource.username=testuser
spring.datasource.password= testuser@123
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driver-class-name= com.mysql.cj.jdbc.Driver

dockerfile:

FROM openjdk:17
ADD target/springboot-crud-api-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-jar","app.jar"]

docker-compose.yml:

version: '3.8'

services:
DB_containerfile:
image: mysql:latest
container_name: DB_containerfile
environment:
- MYSQL_ROOT_PASSWORD=////////////
- MYSQL_DATABASE=phase2
- MYSQL_USER=testuser
- MYSQL_PASSWORD=testuser@123

backend_containerfile:
image: backend_image
container_name: backend_containerfile
ports:
- 8080:8080
build:
context: ./
dockerfile: Dockerfile
depends_on:
- DB_containerfile

NOTE: I assigned the password that I enter when I write this command on the cmd "mysql -u root -p" to MYSQL_ROOT_PASSWORD

Spring boot log:

What I tried:
1)I tried docker volume prune.
2)I tried removing the

- MYSQL_USER=testuser
- MYSQL_PASSWORD=testuser@123
  spring.datasource.username=testuser
  spring.datasource.password= testuser@123`

and only going with

- MYSQL_ROOT_PASSWORD=////////////

3)I tried both

spring.datasource.driver-class-name= com.mysql.cj.jdbc.Driver spring.datasource.driver-class-name= com.mysql.jdbc.Driver

4)I put allowPublicKeyRetrieval=true in spring.datasource.url
And many other thing I tried but the result remained the same.

Sorry, for the long question but I really tried to figure out the problem by myself but now I need someone’s insight. And thank you.

    Thankfully I found the problem it was because I haven't connected the database and spring io. I will post the solution for my case, in case it helps someone.

    spring.datasource.url=jdbc:mysql://DB_containerfile:3306/phase2?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC
spring.datasource.username=testuser
spring.datasource.password= testuser@123
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driver-class-name= com.mysql.jdbc.Driver

    FROM openjdk:17
ADD target/*.jar app.jar
ENTRYPOINT ["java","-jar","app.jar"]

    then run the following commands in the project terminal:

    docker-compose down
mvn clean
mvn clean install -DskipTests=true
docker network ls
docker network create spring-net  //if not created
docker-compose up //then CTRL+C
docker network connect spring-net DB_containerfile
docker container inspect DB_containerfile
docker ps -a
docker-compose up

    try to use this driverClassName in application.properties

    spring.datasource.driverClassName=com.mysql.jdbc.Driver

    Have you tried to start only Mysql db in the container and connect to it from you IDE?
