现象：
采样springboot 2.3.11.RELEASE + liqubase 是报错

原因
DATEEXECUTED字段在数据库中为timestemp类型,当使用的数据库驱动包版本较新时(这里使用的是8.0.23)返回的类型为LocalDateTime,强转为string导致报错.
解决方案一
修改驱动包版本到8.0.19,服务正常启动
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.19</version>
<exclusions>
<exclusion>
<groupId>com.google.protobuf</groupId>
<artifactId>protobuf-java</artifactId>
</exclusion>
</exclusions>
</dependency>

解决方案二
将liqubase版本升级值4.3.2以上
