3. 原因及解决方式

异常原因是Druid和MyBatis Plus版本不兼容

方式1

将MyBatis Plus版本降为3.1.0

<dependency>
	<groupId>com.baomidougroupId>
	<artifactId>mybatis-plus-generatorartifactId>
	<version>3.1.0version>
dependency>
<dependency>
    <groupId>com.baomidougroupId>
    <artifactId>mybatis-plus-boot-starterartifactId>
    <version>3.1.0version>
dependency>
<dependency>
	<groupId>com.alibabagroupId>
	<artifactId>druid-spring-boot-starterartifactId>
	<version>1.1.10version>
dependency>

方式2

将Druid版本升为1.1.20

<dependency>
	<groupId>com.baomidougroupId>
	<artifactId>mybatis-plus-generatorartifactId>
	<version>3.2.1.3-SNAPSHOTversion>
dependency>
<dependency>
    <groupId>com.baomidougroupId>
    <artifactId>mybatis-plus-boot-starterartifactId>
    <version>3.2.1.3-SNAPSHOTversion>
dependency>
<dependency>
	<groupId>com.alibabagroupId>
	<artifactId>druid-spring-boot-starterartifactId>
	<version>1.1.20version>
dependency>

方式3

修改LocalDateTime类型为Timestamp类型
