原因： pom.xml 依赖包导入错误

		<dependency>
		    <groupId>org.mybatis</groupId>
		    <artifactId>mybatis-spring</artifactId>
		    <version>1.3.1</version>
		</dependency>
		
		
		
		<!-- https://mvnrepository.com/artifact/org.mybatis/mybatis -->
		
		<dependency>
		    <groupId>org.mybatis</groupId>
		    <artifactId>mybatis</artifactId>
		    <version>3.4.6</version>
		</dependency>
		

处理：删除上面导入的错误 mybatis 和 mybatis-spring  jar 包，导入  mybatis-spring-boot-starter  jar 包

        <dependency>
		   <groupId>org.mybatis.spring.boot</groupId>
           <artifactId>mybatis-spring-boot-starter</artifactId>
           <version>1.3.2</version>
