服务器时区值"AEST"无法识别或代表多个时区

Question

我正在尝试设置一个简单的hibernate应用程序,当我运行它时,我得到一个充满错误的堆栈跟踪.

我的文件中有以下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,似乎是一种非常简单的方法,但仍然会出现错误:

// 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);

执行上面的操作后,我得到一个很长的堆栈跟踪...... System.out.println也没有打印...所以连接似乎没有连接.

You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

我在这里专注于这个错误:

服务器时区值"AEST"无法识别或代表多个时区.如果要使用时区支持,则必须配置服务器或JDBC驱动程序(通过serverTimezone配置属性)以使用更具体的时区值.

我不确定我是如何解决这个问题的？

编辑:

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

sun.util.calendar.ZoneInfo [ID = "澳大利亚/墨尔本",偏移= 36000000,dstSavings = 3600000,useDaylight =真,过渡= 142,lastRule = java.util.SimpleTimeZone中[ID =澳大利亚/墨尔本,偏移= 36000000, dstSavings = 3600000,useDaylight =真,startYear = 0,STARTMODE = 3,startMonth = 9,朝九特派= 1,startDayOfWeek = 1,开始时间= 7200000,startTimeMode = 1,endMode = 3,endMonth = 3,endday指定= 1,一个endDayOfWeek = 1,结束时间= 7200000,endTimeMode = 1]]

编辑:

所以我查看了标记的问题,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.下面是我的新连接网址.如您所见,我将serverTimezone更改为打印的Timezone.getDefault()

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

Answer 1

尝试添加这些参数..

jdbc:mysql://localhost:3306/fussa?useLegacyDatetimeCode=false&serverTimezone=UTC

我正在使用mysql-connector-java 6.0.4

Answer 2

结果6.x不兼容,转而5.1.39修复它.

Answer 3

正确的解决方案，即AEDT的恕我直言，是按以下方式更改网址，

jdbc:mysql://localhost:3306/sampledb?serverTimezone=Australia/Sydney

Answer 4

jdbc:mysql://localhost:3306/fussa?useLegacyDatetimeCode=false&serverTimezone=UTC

使用&代替&。

您也可以尝试在mysql上更改时区：

SET GLOBAL time_zone = '00:00'; 

并查看当前设置：

SELECT @@global.time_zone, @@session.time_zone;
