I want to enable SSL connections while connecting to MySQL. Ideally my application should through exception because I have still not configured certificates while starting the application. But it is getting successfully restarted and able to connect to DB. I am using MySQL version 8 and spring boot 2.6.
spring.datasource.url=jdbc:mysql://localhost:3306/sms?verifyServerCertificate=true&useSSL=true&requireSSL=true

#spring.datasource.password=root

I have test case that works fine in my local eclipse environment.
#Test
#Order(1)
void testTitle(#Arguments("--headless") ChromeDriver driver) {
driver.get("https://google.com");
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
assertThat(driver.getTitle(), containsString("Google"));
}
But when I used the same in Gitlab it fails. I used the following docker image: maven:3.3.9-jdk-8.
It downloads and extracts chrome driver

Any idea from anyone?
I found the issue and resolved it. Needed to use another docker image maven-chrome.
I am currently following along with this document:
https://spring.io/guides/gs/accessing-data-mysql/
and when I build using Gradle, the process does not finish executing.

I am new to Spring and starting a project from the ground up and do not know where to begin looking to solve this issue.
You are not just building the application - you are actually running it. And since it is a web application, listening to web requests on localhost:8080/demo, it runs until you exit it with ctrl+c.
i not conection.
have db in RDS amazon and have app in spring boot with hibernate...
state db is public..
i have conexion in local with workwench mysql. but not with app..
HELP ME PLEASE!!
Loading class com.mysql.jdbc.Driver'. This is deprecated. The new driver class is com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

Have you inserted dependency(maven or gradle whatever you used to build the application) of mysql connector/jdbc driver for mysql, Make sure you've compatible version of jdbc mysql connector and your mysql version. Also keep in mind if your master user password and credentials maintained in your application properties file along with datasource url.
We have updated our Spring Batch based application to the newest version of Spring Batch 4.x and Boot 2.0.x and having some problems with the HikariCP MySQL connection pool.
If I use the default maxPoolSize of 10 connections and I'm using 5 threads which each starts a simple dummy job this works ok. (Using SimpleJobLauncher). All Jobs are started immediately and after that the HikariCP pool has all used connections returned.
The problem starts when I do the same but then with 11 threads. Then I see that the application hangs until a connection timeout, and then the jobs are started. I expected that the first 10 jobs will start and after the first one finished the 11th job...
Before the jobs start I see this:
HikariPool-1 - Pool stats (total=10, active=0, idle=10, waiting=0)
Now I start 11 jobs and the application will hang for 30 seconds...

The thread limit needs to be less than the maximum pool size of the datasource that spring batch is using with its jobrepository. So for your case, since your datasource pool size is 10, you should use no more than 9 threads.
In the case of an asynchronous taskExecutor(TaskExecutor) the number of concurrent tasklet executions can be throttled (beyond any throttling provided by a thread pool). The throttle limit should be less than the data source pool size used in the job repository for this step.

Hello everybody I am trying to connect my Spring boot App with Mysql but unfortunately it does not work.
application.properties file:
spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.datasource.username=root

# = 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

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
