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.username=root
#spring.datasource.password=root

I have test case that works fine in my local eclipse environment.
#Test

But when I used the same in Gitlab it fails. I used the following docker image: maven:3.3.9-jdk-8.

I am currently learning more about implementing JDBC and using databases in a Spring Boot webapp, and I encountered the following Stack Trace written in the bottom of the post.
I have created a simple Employee model, and I am trying to execute some database code on the same class which my main() lies in. The model and the main class are the only two java files existing in this whole project. I am trying to implement the following run() code that overrides the one from the interface, CommandLineRunner, but I do not get the logs that should come after log.info("Part A:"):
log.info("Part A:")
employees.forEach(employee -> {log.info(employee.toString());
log.info("part a");});
--Things I noticed:
I noticed that the last line of the log before the stack trace starts comes from: "Thread-1" instead of "main". I think that means that a thread from somewhere other than the main encountered an error and closed connection before when it should close normally.
Also, I think that because HikariPool closed before "peer's close_notify", which I presume that it refers to the normal closure of HikariPool, I am not able to see the final bit of logging that I have kept trying to procure. The final bit of logging that I want to see is the logging of the employee that has become inserted into my database.
The final bit of logging that I want to see should be procured from this line of code:
employees.forEach(employee -> {log.info(employee.toString());
log.info("part a");});
--Things to note:
Because of this line in the log, I thought I would see the employee inserted into my database, but when I queried directly on MySQL Command Line Client, it returned an empty set:
2018-11-03 21:08:35.362 INFO 2408 --- [ main] c.j.jdbctest1.JdbcTest1Application : rows affected: 1
I don't understand why a row has been affected when nothing has been inserted into the database.
The stacktrace and logs: (The stacktrace pasted below actually repeats itself several more times but I cut it off for brevity.)

The Java Code:

rs.getString("role"),Status.valueOf(rs.getString("status"))));
log.info("Part A:");
employees.forEach(employee -> {log.info(employee.toString());
log.info("part a");});
}
}
Also just in case this matters, I pasted this code from application.properties:
spring.datasource.url=jdbc:mysql://localhost:3306/employee_database
spring.datasource.username=employee
spring.datasource.password=employee
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
The SSL connection to the database is failing, try changing your datasource URL to:
spring.datasource.url=jdbc:mysql://localhost:3306/employee_database?useSSL=false
The warning looks like a MySQL driver bug with Java 11 and SSL enabled : https://bugs.mysql.com/bug.php?id=93590
Deactivating encryption because of a driver warning is a bad idea.
Your insertion problem looks more like a classic transaction issue though, I doubt it is related to the SSL warning.
This Worked for me
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
<version>8.0.20</version>
</dependency>
I also faced the same issue.
if you look the the stacktrace, it's cleary mentioned what to do -
Sat Mar 16 09:00:01 IST 2019 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'.
You need either to explicitly disable SSL by setting **useSSL=false**, or set **useSSL=true** and provide truststore for server certificate verification.
so after disabling the ssl by making changes in data source url solved the problem -
spring.datasource.url=jdbc:mysql://localhost:3306/security?useSSL=false
To solve this problem, it took me about three days.
(Edit: This is a workaround for testing and not actually a solution.)
At first, I started solving the problem from trying to configure my own SSL for mysql, and I spent quite a few hours on that. Too much time had passed until I realized configuring it had to do with Cmake and C++, which made me give up. It was very frustrating. However I did not give up and tried to disable SSL entirely through a method that hasn't been found. And I eventually did find the method. Here it is:
You have to use the legacy password for MySQL. The legacy password is the way MySQL authenticated things in version 5.7x.
Open up the MySQL installer again, and reconfigure the MySQL Server settings.
When you get there you will see this screen:
The screen that you should get to
You might get some errors when reaching the final stage of the reconfiguration:
I had problems at the final stage I had no idea how to fix so I uninstalled MySQL altogether. I use windows. I deleted the MySQL project root directory from Program Files to uninstall MySQL. I also deleted the databases saved in Program Data (a hidden folder in the C Drive) because I wanted to start afresh(WARNING: this will delete all your previously saved data!). Uninstalling MySQL from the control panel might not be enough to completely erase MySQL from your computer.
Delete all *.pem files in C:\ProgramData\MySQL\MySQL Server 8.0\Data. (or move it somewhere else, which is what I did)
You might not see ProgramData in the C Drive. That is because it is a hidden folder. In order to see hidden folders:
search for folder options in the control panel.
Go to view.
Under 'Advanced settings' and under 'Hidden files and folders' of that, click "Show hidden files, folders, and drives."
Go to C:\ProgramData\MySQL\MySQL Server 8.0 and open my.cnf (or my.ini). Add the following line after [mysqld]:
ssl=0
Then save. It should work now.

My similar problem in a tomcat trying to conect via ssl to Aurora mysql (AWS)
I solved the problem by updating the driver version from 'mysql-connector-java-5.1.40.jar' to 'mysql-connector-java-5.1.49.jar', and installing a root CA into ceacerts:
keytool -import -trustcacerts -file rds-ca-2019-root.pem -keystore /<your_java_home>/lib/security/cacerts
Hope be use to you
Try using the following URL. As they suggested use useSSL=false Also, Make sure to use <&> instead of just & when you have multiple properties defined in your URL.
jdbc:mysql://localhost:3306/TestDB?serverTimezone=PST&useSSL=false
I was also facing the same issue
But then i updated the mysql-connector-java version from 5.1.46 to 8.0.20 and by changing com.mysql.jdbc.Driver to com.mysql.cj.jdbc.Driver
it solved my issue
My similary prolem is in spark,
I solove the problem by down the java verion from
'openjdk version "1.8.0_275"' to 'openjdk version "1.8.0_265"',
hope be use to you
I had this issue and decided to use Carrier Pigeon Protocol's solution until I accidentally solved it by updating Tomcat from version 9.0.12 to 9.0.16.
I faced a similar issue when I upgraded the Java version in my server to 11 from 8.
The spring boot started supporting Java 11 from 2.1 and onwards. So make sure your project's dependencies are also updated accordingly. This is relevant for this answer as SpringBoot also influence MySQL connector, Hibernate core, and other dependencies.
The inability to connect to DB was resulting in some more NoClassDefFoundErrors. So make sure you solve this first before looking into other errors.
An example pom dependency for the SpringBoot starter
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.12.RELEASE</version>
<relativePath />
</parent>
Hope this helps someone.

I had exactly the same problem, I also modified a false my useSSL like this useSSL=false and it works fine.
I think for those who use intelliJ ultimate the error the problem does not arise. But for those who use the community version "yes" also for those who are on netbeans like my case. This concerns the management of persistence.xml files and the EntityManagerHolder file
Rather than disabling SSL/TLS I appended the following to the database connection string: &enabledTLSProtocols=TLSv1.2
I installed sonarqube-6.3.1 in my machine and created a database in mysql db named 'sonarqubedb'. Now when I am making changes in sonar.properties file to use the database, sonarqube is not getting started and throwing error msg, but If I am using the default DB configuration (and NOT mysql), I am able to start.
Could somebody please provide me a solution what is going wrong when I am using mysql db.
My sonar.properties file be like:
sonar.jdbc.username=root
sonar.jdbc.password=
sonar.jdbc.url=jdbc:mysql://localhost:3306/sonarqubedb?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance

Go to your sonarqube/logs directory. You'll find several log files and one of them will contain the detailed error on why sonarqube won't start.(you'll have to scroll all the way down inside the files for the latest information iirc)
Go through this sonar documentation, you will get some help -

I had the same issue.
The problem was that my MySQL version didn't meet the minimum requirements.
