MySQL数据库连接时区问题

<!--    组件扫描-->
    <context:component-scan base-package="com"></context:component-scan>
    <!--    数据库连接池配置-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
            destroy-method="close">
            <property name="url" value="jdbc:mysql://localhost:3306/db01"/>
            <property name="username" value="root"/>
            <property name="password" value="zzy"/>
            <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    </bean>

配置中的url这样写的话会报错_如下👇

严重: create connection SQLException, url: jdbc:mysql://localhost:3306/db01, errorCode 0, state 01S00
java.sql.SQLException: The server time zone value '�й���׼ʱ��' 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.

主要原因翻译过来之后显示时区异常👇

服务器时区值 ' й ׼ɦ ' 无法识别或表示多个时区。如果要利用时区支持，则必须将服务器或 JDBC 驱动程序（通过 serverTimezone 配置属性）配置为使用更具体的时区值。

解决办法：👇

将xml中配置url的value改成如下：👇

<property name="url" value="jdbc:mysql://localhost:3306/db01?serverTimezone=GMT%2B8"/>

即加上服务器时区

就好啦！（下面是输出结果）

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
