服务器时区值“ AEST”无法识别或代表多个时区

Question

我试图设置一个简单的hibernate应用程序，当我运行它时，我得到了一个充满错误的堆栈跟踪信息。

我的文件中具有以下Maven依赖项pom.xml：

<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>

我在本地运行的mysql版本是：

5.7.9, for osx10.11 (x86_64)

我正在运行，看来，这是一种非常简单的方法，仍然出现错误：

// 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);

执行完上面的命令后，我得到了很长的堆栈跟踪信息… System.out.println也不打印…因此连接似乎没有建立连接。

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.

我在这里关注此错误：

服务器时区值“
AEST”无法识别或代表多个时区。如果要利用时区支持，则必须配置服务器或JDBC驱动程序（通过serverTimezone配置属性）以使用更特定的时区值。

我不确定该如何解决？

编辑：

打印出时区（System.out.println（TimeZone.getDefault（））;）将打印以下详细信息：

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]]

编辑：

因此，我查看了已标记的问题，并尝试更改我的连接字符串，但它仍然抛出相同的堆栈跟踪。以下是我的新连接网址。如您所见，我将serverTimezone更改为已打印的Timezone.getDefault()

jdbc:mysql://localhost:3306/parking_hib?useLegacyDatetimeCode=false;serverTimezone=Australia/Melbourne;useSSL=false;

原来6.x是不兼容的，正在5.1.39修复它。
