错误排查:首先检查xml中对相关配置文件的引入路径是否正确,本项目中有两处:

对比路径,查看项目文件路径,发现文件都是存在的,说明并不是资源文件路径写错.

路径没有错,而且文件也是确实存在的,检查mvn编译后的文件发现资源文件没有被编译,可以尝试重新编译;仍不能解决时,配置pom文件的build > resources标签,配置如下:

<build>
  <finalName>ssm</finalName>
    <resources>
      <resource>
        <directory>src/main/resources</directory><!-- 资源文件所在文件夹 -->
        <includes>
          <include>*.properties</include><!-- 具体路径,按自己的项目配置 -->
          <include>**/*.properties</include>
          <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering>
      </resource>
    </resources>
    ...
</build>

原因是mvn在编译时,会将.properties和.xml文件过滤,不编译这些文件,在最后的war包中自然没有这些文件,引用时也就报错了.
