 二、分析

出现该异常的原因是，mapper.xml 文件没有被加载

三、解决。在 pom.xml 中添加以下内容

<!-- 如果不添加此节点 mybatis 的 mapper.xml 文件都会被漏掉。 -->
<build>
    <resources>
        <!-- 将 src/main/java 作为资源文件目录 -->
           <resource>
               <directory>src/main/java</directory>
               <includes>
                   <include>**/*.properties</include>
                   <include>**/*.xml</include>
               </includes>
               <filtering>false</filtering>
           </resource>
           <!-- 将 src/main/resources 也作为资源文件目录 -->
           <resource>
               <directory>src/main/resources</directory>
               <includes>
                   <include>**/*.properties</include>
                   <include>**/*.xml</include>
               </includes>
               <filtering>false</filtering>
           </resource>
       </resources>
</build>
