springboot 项目启动时报如下错误

[AbstractApplicationContext.java:592] → [Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'loginController': Unsatisfied dependency expressed through field 'userService': Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'userMapper': Error creating bean with name 'userMapper' defined in file [D:\projects\tutorails_kanomoku\practisesvr\target\classes\com\zhangziwa\practisesvr\mapper\UserMapper.class]: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required]

原因 版本不兼容

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.0.5</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.0</version>
</dependency>

方案：升级 mybatis-spring-boot-starter 版本即可

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>3.0.2</version>
</dependency>
