Spring boot container can't connect to mysql container [duplicate]

How to communicate between Docker containers via "hostname"
(5 answers)
Closed 6 months ago.
I am trying to containerize a Spring Boot application. The application uses JPA, so in order to run the app, it needs to be connected to a db.
I ran the application locally and successfully connected to a MySQL I had running in a container. However, when I tried running the application container, it was unable to connect to the mysql container.
What I've tried:
In application.properties
Changed spring.datasource.url hostname from localhost to mysql-server (mysql container name)
Added SPRING_DATASOURCE_URL env to docker-compose.yml
Manually build both sql and application containers and connected them to a network
Included depends_on dependency to backend container definition
And a lot more that I can't remember at the moment but will include when they come to me.
Anyways, I can't figure out what I'm missing so any help on this issue would be greatly appreciated.

Why my spring boot Dockerfile can't connect to AWS RDS?

I am creating a spring boot Api. that Api uses a remote database (RDS). When I run it in my machine the app can connect normally to datasource, but when I build a Docker image and run it can't connect.
My Dockerfile:
FROM openjdk:11-jre-slim
RUN groupadd -r fps && useradd --no-log-init -r -g fps flavio
USER flavio
ARG DEPENDENCY=target/dependency
COPY ${DEPENDENCY}/BOOT-INF/lib /app/lib
COPY ${DEPENDENCY}/META-INF app/META-INF
COPY ${DEPENDENCY}/BOOT-INF/classes /app
ENTRYPOINT ["java","-cp","app:app/lib/*","com.fps.app.FpsApplication"]
My application.properties:
server.port=8080
spring.datasource.url=jdbc:mysql://my_db_endpoint?useSSL=false&useLegacyDatetimeCode=false
spring.datasource.username=my_username
spring.datasource.password=my_pwd

2021-04-21 12:11:11.544 WARN 1 --- [ main] o.h.e.j.e.i.JdbcEnvironmentInitiator : HHH000342: Could not obtain connection to query metadata
Obs: the inbound security group of my RDS is allowing all source in 3306 port.
Does anybody know what is wrong?

When I tried to instantiate JobOperator then a ClassNotFoundException was thrown. (org.apache.commons.dbcp2.BasicDataSource)

I am starting with a basic Spring Batch getting started example. I have only added one instruction to stop the job in its beggining but I am getting a exception at runtime.
https://github.com/brunogcarneiro/spring-batch-error/blob/main/src/main/java/com/example/batchprocessing/JobCompletionNotificationListener.java
#Override
public void beforeJob(JobExecution jobExecution){
log.info("Job starting!");
BatchRuntime.getJobOperator().stop(jobExecution.getId());
log.info("Job stoped!");
}
The exception is thrown when I invoke getJobOperato(). I cant figure out why this is happening once I am using the spring-boot-starter-batch.
The complete source can be found at: https://github.com/brunogcarneiro/spring-batch-error
The stacktrace is:

Spring JPA - Error Hibernate on MySQL database creating Foreing Keys

I am using Spring Boot with JPA and My-SQL connector to connect to my db. I am using the persisntance from Hibernates to create the tables and to query. But when I create an relation between to Models (Entities), the Hibernate is unable to create the foreign keys in my database, giving the following error.

I think your Database user doesn't have the alter table permissions.
GRANT ALTER ON tableName TO 'someuser'#'somehost';
use this command to get those permissions

java.sql.SQLException: Access denied for user 'root'#'localhost' (using password: YES) in spring using mysql

I am new in spring that's why i don't know much about it. I am not able to connect MySQL to my application.
Can anyone help me?
My application.properties file is here:
spring.datasource.url=jdbc:mysql://localhost:3306/nicetrydata?useSSL=false

spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto = update
Every time I run my application I am getting error like:

This reads like having nothing to do with Spring Boot, but the wrong username/password combination.
Have you tried logging in to your MySQL Database with said credentials? With MySQL client or workbench?

Please check if username and password are wrong and check the grant of user.
Take a look at here: Spring Boot MySql Access denied for user 'root'#'localhost'

i got it, you have an extra white space at the end of your pass(root ). delete it and it works
spring.datasource.password=root
and another thing that you should notice is that "com.mysql.jdbc.Driver" is deprecated, use this"com.mysql.cj.jdbc.Driver"
