Java 服务器时区值'；AEST&x27；无法识别或表示多个时区

我正在尝试设置一个简单的hibernate应用程序，当我运行它时，我会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>

我正在运行一个非常简单的方法，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);

执行上述操作后，我得到一个很长的堆栈跟踪…System.out.println也不打印…因此连接似乎没有连接

原来

6.x

不兼容，移动到

5.1.39

修复了它。

尝试添加这些参数

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

---

我使用的是mysql连接器java 6.0.4

引发异常，因为mysql服务器时区（从系统时区继承）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“澳大利亚/悉尼”。请看这个令人敬畏的回复，了解详细信息：

• 使用时区信息填充mysql架构：

mysql\u tzinfo\u to\u sql/usr/share/zoneinfo | mysql-u root-p mysql

• 从mysql运行：

设置全球时区='澳大利亚/悉尼'


重新启动mysql服务器

使用
&而不是
&

您也可以尝试更改mysql上的时区：

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

-

这种组合对我很有效。
使用默认值

Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/web_student_tracker?user=root&password=&useLegacyDatetimeCode=false&serverTimezone=UTC");

您好，您需要在URL说明符中指定，如下所示

 @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;
    }

在上面的代码片段中，查看一下
setUrl
property
这就是MySQLWorkbench版本的问题。升级至最新版本8.0，然后在jdbc URL中添加serverTimezone=UTC

String url=“jdbc:mysql://localhost:3306/your_db?useSSL=false&serverTimezone=UTC";
 对于AEDT，正确的解决方案IMHO是按如下方式更改URL

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

我有一个类似的问题，我使用的是mysql连接器java 8.0.15（最新版本），但出于某种原因，它仍然给我一个时区错误，我将它改为mysql连接器java 8.0.13，就这样做了。希望这是有用的。
如果使用Spring Boot，请尝试在localhost参数后添加一个问号，如下所示：

?serverTimezone=UTC&useLegacyDatetimeCode=false

例如，我有一个名为springboottutorial的mysql数据库。在本例中，参数如下所示：

spring.datasource.url=jdbc:mysql://localhost:3306/springboottutorial?serverTimezone=UTC&useLegacyDatetimeCode=false
在MySQL中：您可以使用以下命令：

第一个解决方案：将服务器时区=UTC添加到连接url

spring.datasource.url=jdbc:mysql://localhost:3306/mydb?useSSL=false&serverTimezone=UTC


第二种解决方案：nMySQLmy.ini文件集默认时区值如下所示

# Set default time zone
default-time-zone = '+08:00'


我通过在数据库名称后面添加
“？serverTimezone=America/Los_Angeles”
解决了这个问题。我来自西海岸，我的地区名称是“美国/洛杉矶”
。如果您不确定您的时区名称，请在RHEL/UBUNTU/CENTOS上运行下面的命令

11:42 AM  ✔ user1 sfo-server1 Δ [~] Ω  timedatectl | grep "Time zone"
       Time zone: America/Los_Angeles (PDT, -0700)

解决方案：

jdbc_connection_string => "jdbc:mysql://localhost:3306/movielens**?serverTimezone=America/Los_Angeles**"

加载时区数据后

SET GLOBAL time_zone = 'Australia/Sydney';

为我工作

在我的例子中，我希望设置是持久性的，而这些都不适用于我持久化时区，最后我选择了设置启动参数，如下所示

--default-time-zone=Australia/Sydney

最常见的选择是在my.cnf中设置，但这对我也不起作用

注意：我的是CentOS 8&MySql 8
它是否与其他连接器（如C或ODBC）一起工作？没有尝试过吗？我该如何测试这一点@Michael OJDBC似乎是最流行的？例如，在PHP或Windows ODBC或unixODBC中。客户端和服务器上的属性
user.timezone
（
timezone.getDefault（）
）表示什么？您需要一个“实时”时区。CEST（中欧标准时间）也是如此——在这里，你必须决定欧洲/柏林或欧洲/巴黎等。对于AEST来说，这似乎是澳大利亚/悉尼、澳大利亚/塔斯马尼亚或澳大利亚/维多利亚。这对我来说很有效。我更新了我的Spring application.properties文件。我想将其设置为我的本地时区（山区时间），并希望它足够智能，能够处理夏令时（即MDT变为MST，全年再次返回）。此参数也可以添加到phpStorm数据库管理器中以进行连接。我将Linux服务器的/etc/localtime从/usr/share/zoneinfo/US/Pacific更新为/usr/share/zoneinfo/America/Los_Angeles，然后重新启动mysql服务，这为我解决了问题。我也遇到了同样的问题，这篇帖子解决了这个问题。无论如何，如果我在调试模式下启动应用程序，我会遇到以下异常：“线程中的异常”main“com.mysql.cj.jdbc.exceptions.CommunicationsException:通信链路故障成功发送到服务器的最后一个数据包是0毫秒前的。驱动程序没有从服务器收到任何数据包”。有什么想法吗？为我工作！！！升级到8.0.11也解决了这一问题。连接器8.0.15似乎已损坏，需要上述修复。默认情况下，8.0.23使用本地时区，因此默认情况下不存在此问题，也适用于我，在使用mysql 8.0的SpringBoot上，这是不正确的；该URL未嵌入HTML页面，因此不应进行HTML转义。我需要与您联系，先生，在CentOS需要一些帮助。你可以在推特@ankitmishara上给我发DM吗？或者你可以给我一些我可以和你交谈的东西。
11:42 AM  ✔ user1 sfo-server1 Δ [~] Ω  timedatectl | grep "Time zone"
       Time zone: America/Los_Angeles (PDT, -0700)

jdbc_connection_string => "jdbc:mysql://localhost:3306/movielens**?serverTimezone=America/Los_Angeles**"

SET GLOBAL time_zone = 'Australia/Sydney';

--default-time-zone=Australia/Sydney
