关于java：服务器时区值’AEST’无法识别或代表多个时区


The server time zone value 'AEST' is unrecognized or represents more than one time zone

我正在尝试设置一个简单的休眠应用程序，当我运行它时，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>mysql</groupId>
        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)

我正在运行一个非常简单的方法，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);

在执行上述操作之后，我得到了一个长的堆栈跟踪…system.out.println也没有打印…所以连接似乎没有连接。

我关注的是这个错误：

The server time zone value 'AEST' is unrecognized or represents more
than one time zone. You must configure either the server or JDBC
driver (via the serverTimezone configuration property) to use a more
specifc time zone value if you want to utilize time zone support.

我不确定如何修复它？

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]]

号编辑：

所以我查看了标记的问题，并尝试更改连接字符串，但它仍在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EDOCX1[1]

1
jdbc:mysql://localhost:3306/parking_hib?useLegacyDatetimeCode=false;serverTimezone=Australia/Melbourne;useSSL=false;
相关讨论

尝试添加这些参数..

1
jdbc:mysql://localhost:3306/fussa?useLegacyDatetimeCode=false&serverTimezone=UTC

我使用的是MySQL连接器Java6.0

相关讨论

结果发现6.x不兼容，移动到5.1.39修复了它。

相关讨论

对于AEDT，适当的解决方案是如下更改URL，

1
jdbc:mysql://localhost:3306/sampledb?serverTimezone=Australia/Sydney
1
jdbc:mysql://localhost:3306/fussa?useLegacyDatetimeCode=false&amp;serverTimezone=UTC

号

用&代替&。

您也可以尝试在MySQL上更改时区：

1
SET GLOBAL time_zone = '00:00';

并查看当前设置：

1
SELECT @@global.time_zone, @@session.time_zone;

。

引发异常的原因是MySQL服务器时区(从系统时区继承)的格式与MySQL连接器预期的格式不同。您需要将mysql时区设置为"澳大利亚/悉尼"。查看这个令人敬畏的响应以了解详细信息：MySQL是否应该将其时区设置为UTC？

  • 用时区信息填充mysql模式：

埃多克斯1〔2〕

  • 从mysql运行：

埃多克斯1〔3〕

  • 重新启动MySQL服务器

这就是mysqlWorkbench版本的问题。升级到8.0的最新版本，然后在JDBC URL中添加serverTimeZone=utc。

string url="jdbc:mysql://localhost:3306/您的数据库？usessl=false&serverTimeZone=utc"；

build.gradle>

1
compile group: 'mysql', name: 'mysql-connector-java', version: '8.0.11'

application.properties>

1
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)

。

这个组合对我有用。

使用默认值

1
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/web_student_tracker?user=root&password=&useLegacyDatetimeCode=false&serverTimezone=UTC");

嗨，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，可以查看setUrl属性
