本文档介绍了一个MyBatis在尝试连接MySQL数据库时遇到的时区识别错误。错误信息表明服务器时间戳值无法识别或代表多个时区。解决方案是在SqlMapConfig.xml的URL配置中添加`serverTimezone=UTC`参数。通过这个修改，可以确保数据库连接使用正确的时区设置，从而避免查询异常。

解决方法

再SqlMapConfig.xml文件中的url配置项中加入serverTimezone=UTC

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <environments default="dev">
        <environment id="dev">
            <transactionManager type="JDBC"></transactionManager>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.cj.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/db1?serverTimezone=UTC"/>
                <property name="username" value="root"/>
                <property name="password" value="root"/>
            </dataSource>
        </environment>
    </environments>
