I’m trying to setup a simple hibernate application, when I run it I get a stack trace full of errors.
I have the following maven dependencies in my pom.xml file:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.2.0.Final</version>
</dependency>
<!-- http://mvnrepository.com/artifact/mysql/mysql-connector-java -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>6.0.2</version>
</dependency>
And the mysql version I’m running locally is:
5.7.9, for osx10.11 (x86_64)
I’m running, what seems, a very simple method, and still getting errors:
// create session factory
SessionFactory factory = new Configuration()
.configure("hibernate.cfg.xml")
.addAnnotatedClass(Model.class)
.buildSessionFactory();
// create session
Session session = factory.getCurrentSession();
Model newModel = new Model("....", "...", "...");
// start a transaction
session.beginTransaction();
// save the student object
System.out.println("Saving the model...");
session.save(newModel);
After the above is executed, I get a long stack trace…The System.out.println doesn’t print either…So the connection just doesn’t seem to be connecting.

Thu Jun 09 17:36:28 EST 2016 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.

I’m focused on this error here:
The server time zone value ‘AEST’ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
I’m unsure how I fix it?
Edit:
Printing out the Timezone (System.out.println(TimeZone.getDefault());) prints the following details:
sun.util.calendar.ZoneInfo[id=”Australia/Melbourne”,offset=36000000,dstSavings=3600000,useDaylight=true,transitions=142,lastRule=java.util.SimpleTimeZone[id=Australia/Melbourne,offset=36000000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=9,startDay=1,startDayOfWeek=1,startTime=7200000,startTimeMode=1,endMode=3,endMonth=3,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=1]]
Edit:
So I looked at the question which was flagged, and tried to change my connection string, but it’s still throwing the same stack trace. Below is my new connection url. As you can see I changed the serverTimezone to that of the printed Timezone.getDefault()
jdbc:mysql://localhost:3306/parking_hib?useLegacyDatetimeCode=false;serverTimezone=Australia/Melbourne;useSSL=false;

Answer
Turns out 6.x wasn’t compatible, moving to 5.1.39 fixed it.
