错误： tomcat启动报错日志

原因：

一直是不能创建bean的样子，经过一行一行地阅读报错信息。最后发现mybatis的映射xml文件居然没有找到，然后又去翻classes目录，结果果然没有，因为自己的mybatis的mapping目录是在src/main/java 在编译时没有保留配置文件，导致tomcat启动无法找到对应的目录从而报错

解决办法:

在pom文件中加入如下代码:

<build>
    <resources>
      
      <resource>
        <directory>src/main/javadirectory>
        <includes>
          <include>**/*.xmlinclude>
        includes>
        <filtering>truefiltering>
      resource>
    resources>
build>
