Modifying the port and configuration after spring boot is packaged and released does not work

The development environment is good. After
publishing to the server, the port is changed and it is not normal. The port number configured in the development environment is still used...

The configuration in pom.xml is as follows.

 <resources>
     <resource>
         <directory>src/main/java</directory>
         <includes>
             <include>**/*.*</include>
         </includes>
     </resource>
     <resource>
         <directory>src/main/resources</directory>
         <includes>
             <include>**/*.*</include>
         </includes>
     </resource>
 </resources>

All as follows

<build>
		<finalName>bsn-java</finalName>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
        </resources>

Later, I really couldn’t find the reason.
I started to guess the mode. I released the packaged application.properties and placed it in the classes directory.
Is it misplaced? So I took a try. Moved up one level. . It turned out to be amazing...
