reason

Because the userimpl.XML file under COM/CTH/Dao/ has not been compiled into the corresponding directory under the target/classes directory, I don’t believe you can find it under the target/classes directory in the project. You can’t find it

Solution:

Method 1: put the files in COM/CTH/Dao directory under resource

Method 2: add the following code to the POM file

<build>
    <resources>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.properties</include>
          <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering>
      </resource>
    </resources>
  </build>
