SpringBoot升级到3.3.2版本，JDK升级到17，引入Mybatis-plus后启动报错：Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

【原因分析】

SpringBoot2.x版本和JDK8没有这个问题，当SpringBoot升级到3.3.2版本，JDK升级到17版本，再引入Mybatis-plus后就会启动报错，不能自动加载sqlSessionFactory。

 

【解决方案】

需要升级mybatis-plus的坐标依赖：

由：mybatis-plus-boot-starter

 

<!--<dependency>

    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.5.7</version>
</dependency>-->

修改为：mybatis-plus-spring-boot3-starter

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-spring-boot3-starter</artifactId>
    <version>3.5.5</version>
</dependency>
