1在SpringBoot项目下的Mapper文件添加
import org.mybatis.spring.annotation.MapperScan;然后再填写上MapperScan
2完成这一步之后如果我们的Java运行环境JRE与mybatis-spring库中的MapperScan.class类文件不兼容会报java: 无法访问org.mybatis.spring.annotation.MapperScan 错误的类文件: /D:/Program Files/apache-maven-3.6.0/repository/org/mybatis/mybatis-spring/3.0.3/mybatis-spring-3.0.3.jar!/org/mybatis/spring/annotation/MapperScan.class 类文件具有错误的版本 61.0, 应为 52.0 请删除该文件或确保该文件位于正确的类路径子目录中。的错误。
详细的解决办法见博客SpringBoot异常类文件具有错误的版本 61.0, 应为 52.0的解决办法
