我的<mybatis:scan />这个节点在xml文件中报错，我应该如何解决，求大神帮帮忙

import org.mybatis.spring.annotation.MapperScan;

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

pom添加以下两个依赖
 <dependency>
   <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
  <version>3.2.8</version>
 </dependency>
<dependency>
     <groupId>org.mybatis</groupId>
     <artifactId>mybatis-spring</artifactId>
  <version>1.2.2</version>
 </dependency>

      <!-- mybatis -->22         <dependency>23             <groupId>org.mybatis</groupId>24             <artifactId>mybatis</artifactId>25             <version>3.2.8</version>26         </dependency>27         <dependency>28             <groupId>org.mybatis</groupId>29             <artifactId>mybatis-spring</artifactId>30             <version>1.2.2</version>31          </dependency>

你可能没有导入吧 

import org.mybatis.spring.annotation.MapperScan;
