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：
<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，但仍然会出错：
// 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'无法识别或代表更多 比一个时区。您必须配置服务器或JDBC 驱动程序（通过serverTimezone配置属性）使用更多 如果您想利用时区支持，请指定时区值。
我不确定我是如何解决它的？
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]]
所以我查看了被标记的问题，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;

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
答案 1 :(得分：24)
原来6.x不兼容，转而5.1.39修复它。
答案 2 :(得分：6)
正确的解决方案，即AEDT的恕我直言，如下更改URL
Cartfile答案 3 :(得分：5)
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;
答案 4 :(得分：3)
抛出异常是因为MySql服务器时区（继承自系统时区）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”。请查看详细的响应：Should MySQL have its timezone set to UTC?
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql
SET GLOBAL time_zone = 'Australia/Sydney';

-
mysql --version
mysql Ver 8.0.11 for osx10.13 on x86_64 (Homebrew)
这种组合对我有用。
答案 6 :(得分：2)
这是MySQLWorkbench版本的问题。升级到最新版本8.0，然后在jdbc URL中添加serverTimezone = UTC。
字符串url =“ jdbc：mysql：// localhost：3306 / your_db？useSSL = false＆serverTimezone = UTC”;
答案 7 :(得分：1)
使用默认
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/web_student_tracker?user=root&password=&useLegacyDatetimeCode=false&serverTimezone=UTC");
答案 8 :(得分：1)
如果您使用Spring Boot，请尝试在localhost参数后添加一个问号，并添加以下内容：
?serverTimezone=UTC&useLegacyDatetimeCode=false
例如，我有一个名称为springboottutorial的mysql数据库。在此示例中，参数看起来像这样：
spring.datasource.url=jdbc:mysql://localhost:3306/springboottutorial?serverTimezone=UTC&useLegacyDatetimeCode=false
答案 9 :(得分：0)
嗨，您需要像下面这样在URL说明符中指定
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/jpahibernate?useLegacyDatetimeCode=false&serverTimezone=UTC");
dataSource.setUsername("root");
dataSource.setPassword("Password");
return dataSource;
}
在上面的代码段中，请查看setUrl属性

我有一个类似的问题，我使用的是mysql-connector-java 8.0.15（最新），但是对于某些原因，它仍然给我一个时区错误，我将其更改为mysql-connector-java 8.0.13，做到了。希望有用。
答案 11 :(得分：0)
在MySQL中：您可能会像下面这样使用以下用户：
第一个解决方案：将 serverTimezone = UTC 添加到连接网址
spring.datasource.url=jdbc:mysql://localhost:3306/mydb?useSSL=false&serverTimezone=UTC
第二个解决方案： n个MySQL my.ini 文件集默认时区如下所示的值
# Set default time zone
default-time-zone = '+08:00'
答案 12 :(得分：0)
我通过在数据库名称之后添加# SPICEY DICE Code snippet.
# - Create window
window2 = Tk()
window2.title("SPICEY DICE - Single Player Finish")
# - Label 1
Label(window2, text = "CONGRATULATIONS!").grid(row = 0, column = 0, sticky = W)
# - Label 2
Label(window2, text = "You have finished SPICEY DICE with a score of:").grid(row = 1, column = 0, sticky = W)
# - Text box 1
Output5 = Text(window2, width = 5, height = 1, wrap = WORD, background = "yellow")
Output5.grid(row = 2, column = 0, sticky = W)
# - Button 1
Button(window2, text = "LEADERBOARD", width = 15, command = SPLeaderboard).grid(row = 3, column = 0, sticky = W)
# - Label 3
Label(window2, text = "Close all of the windows to finish.").grid(row = 4, column = 0, sticky = W)
# - Run mainloop
window2.mainloop()
Output5.delete(0.0, END)
Output5.insert(END, str(TotalScore))
来解决此问题。我来自西海岸，区域名称为"?serverTimezone=America/Los_Angeles"。如果不确定时区名称，请在RHEL / UBUNTU / CENTOS上的以下命令中运行
"America/Los_Angeles"解决方案：
11:42 AM ✔ user1 sfo-server1 Δ [~] Ω timedatectl | grep "Time zone"
Time zone: America/Los_Angeles (PDT, -0700)
答案 13 :(得分：0)
加载时区数据后，
SET GLOBAL time_zone = 'Australia/Sydney';
为我工作。
就我而言，我希望设置是持久的，但这些都不适合我来保持时区，最后我使用 option in mysql doc 设置启动参数，如下所示，
--default-time-zone=Australia/Sydney
最常见的选项是在 my.cnf 中设置它，但这对我也不起作用。
注意：我的是 CentOS 8 和 MySql 8
