springboot + tk.mybatis启动报错

简述：项目中使用了 tk.mybatis 的包 启动的时候报错
原因：tk.mybatis中的@MapperScan 依赖于org.mybatis包，这个包没引入。

报错内容：
java.lang.annotation.AnnotationFormatError: Invalid default: public abstract java.lang.Class tk.mybatis.spring.annotation.MapperScan.factoryBean()

如图：

报错时的pom.xml 如图：（此时没有引入org.mybatis）

原因：tk.mybatis中的@MapperScan 依赖于org.mybatis包，这个包没引入。
如图：
点进去tk的MapperScan

点进去tk的MapperFactoryBean

注意：在tk的MapperFactoryBean中引入了org的包内容

解决方案：在pom.xml 中增加org.mybatis的包即可

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.2.2</version>
        </dependency>

解决效果：

启动成功
