错误“java.lang.annotation.AnnotationFormatError: Invalid default: public abstract java.lang.Class org.mybatis.spring.annotation.MapperScan.factoryBean()”
分析和引用的mybatis配置有关
出坑：
修改pom.xml中引用
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.1.2</version>
<scope>test</scope>
</dependency>
删除<scope>test</scope>后出坑。
