我得到的错误类似于你的，但我的服务器时区值是'Afr。舟状骨的西部省 所以我做了这些步骤:

MyError (IntelliJ IDEA社区版):

    InvalidConnectionAttributeException: The server time zone value 'Afr. centrale Ouest' 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 u....

当我把mysql服务器升级到SQL server 8.0 (MYSQL80)时，我遇到了这个问题。

这个问题最简单的解决方案是在MYSQL Workbench中编写下面的命令-

  SET GLOBAL time_zone = '+1:00'

时区之后的值将等于您所在时区的GMT+/-差值。上面的例子是北非(GMT+1:00) /或印度(GMT+5:30)。 这将解决问题。

在Mysql Workbench中输入以下代码并执行查询

显然，要使MySQL JDBC驱动程序5.1.33版本与UTC时区兼容，必须在连接字符串中显式指定serverTimezone。

jdbc:mysql://localhost/db?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC

在阅读了几篇关于这个主题的文章后，测试了不同的配置，并根据这个mysql bug线程的一些见解，我明白了:

the server time zone is important in particular to convert dates stored in the database to the time zone of the application server. there are other implications but this is the most noticeable one GMT x UTC time zone systems. GMT was conceived in the late 19th century and can be shifted between standard time and summer time. this property could lead to a situation where the database server shifts to summer time and the application doesn't notice it (perhaps there are other complications but I didn't research further). UTC does not vary over time (it is always within about 1 second of mean solar time at 0° longitude). serverTimeZone definition was introduced in mysql jdbc connectors versions 5.1 ahead. until version 8 it could be ignored with useLegacyDatetimeCode=true , which in conjunction with useJDBCCompliantTimezoneShift=true would make the application get the database time zone on every connection. In this mode GMT time zones such as 'British Summer Time' would be converted to the internal java/JDBC format. New time zones could be defined in a .properties file such as this one Starting with jdbc driver version 8, automatic time matching (useJDBCCompliantTimezoneShift) and legacy time format (useLegacyDatetimeCode) were removed (see mysql jdbc connector changelog). therefore setting these 2 parameters has no effect as they are completely ignored (new default is useLegacyDateTimeCode=false) In this manner setting serverTimezone became mandatory if any of the time zones (application/database servers) are not in the format 'UTC+xx' or 'GMT+xx' There is no impact of setting server time as UTC (for instance with jdbc:mysql://localhost:3306/myschema?serverTimezone=UTC, even if your application / database servers are not in this timezone. The important is for the application connection string + database to be synchronized with the same time zone. In different words, simply setting serverTimezone=UTC with a different time zone on the database server will shift any dates extracted from the database The MySQL default time zone can be set to UTC+0 with the my.ini or my.cnf files (windows / linux respectively) by adding the line default-time-zone='+00:00' (details in this StackOverflow post) Databases configured on AWS (amazon web services) are automatically assigned UTC+0 default time (see AWS help page here)

我解决了把下面的连接字符串在URL

jdbc:mysql://localhost:3306/db?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC

我在[mysqld]部分添加了mysql配置文件 default_time_zone = ' + 03:00 ' 重启mysql服务器: Sudo服务mysql重启

其中+03:00我的UTC时区。

在我的操作系统ubuntu 16.04上配置文件的路径:

/etc/mysql/mysql.conf.d/mysqld.cnf

警告:如果你所在的时区有夏季和冬季时间。如果要更改时间，必须在配置中更改utc。一年两次(通常)或用sudo设置crontab。

我的url jdbc连接

"jdbc:mysql://localhost/java"

我遇到了同样的错误，在我的情况下，我将服务器端口号更改为3308，之前是3306。这将我的项目连接到MySQL数据库。

这里我们还必须更改连接代码。

Class.forName("com.mysql.cj.jdbc.Driver");
cn=(java.sql.Connection)DriverManager.getConnection("jdbc:mysql://localhost:3308/test2?zeroDateTimeBehavior=convertToNull","root","");

更改连接代码中的端口号也是必要的，如localhost:3308以解决错误。

在我的例子中，还有管理属性。
