服务器时区值“AEST”无法识别或代表多个时区
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pom.xml文件中有以下maven依赖项：
org.hibernate hibernate-core 5.2.0.Final mysql mysql-connector-java 6.0.2
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。

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url。 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;
原来6.x不兼容，转向5.1.39固定它。
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
抛出exception是因为MySql服务器时区（inheritance自系统时区）的格式与mysql连接器所期望的格式不同。 您需要将MySql时区设置为“Australia / Sydney”。 请看这个令人敬畏的响应细节： MySQL是否应将其时区设置为UTC？
- 使用时区信息填充mysql架构：
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql
- 从mysql运行：
SET GLOBAL time_zone = 'Australia/Sydney';
- 重启mysql服务器
jdbc:mysql://localhost:3306/fussa?useLegacyDatetimeCode=false&serverTimezone=UTC
使用& 而不是& 。
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;
build.gradle>
compile group: 'mysql', name: 'mysql-connector-java', version: '8.0.11'
application.properties>
spring.datasource.url=jdbc:mysql://localhost:3306/bookworm?useLegacyDatetimeCode=false&serverTimezone=UTC
–
mysql --version mysql Ver 8.0.11 for osx10.13 on x86_64 (Homebrew)
这种组合对我有用。
使用默认值
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/web_student_tracker?user=root&password=&useLegacyDatetimeCode=false&serverTimezone=UTC");
