The problem of not being able to read @@ after Spring Boot development and compilation and solutions

When using IDEA for Spring Boot project development, if you encounter the problem of not being able to read after compilation@@The problem is usually caused by several reasons:

Resource filtering is not enabled: existIn this case, you need to ensure that resource filtering is enabled, so that Maven will be replaced during construction.@@is the actual profile value. Can be<build>Add the following configuration in the tag:

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

After this configuration, you need to re-execute Maven'scleanandinstallcommand, or execute "Reload All Maven Projects" in IDEA to make the configuration take effect.

Profile configuration: make sureThe corresponding profile has been defined in<activeByDefault>Mark as the default activated profile. For example:

&lt;profiles&gt;
    &lt;profile&gt;
        &lt;id&gt;dev&lt;/id&gt;
        &lt;properties&gt;
            &lt;&gt;dev&lt;/&gt;

5. Clean and re-import the project: Sometimes, IDEA's cache may cause incorrect configuration reads. You can try to clean the cache and restart IDEA, or reimport the Maven project.

6. Check Spring Boot startup class: Make sure there is no hard-coded profile settings on Spring Boot's startup class, which may override external configurations.

Through the above steps, it is usually possible to solve the problem that IDEA cannot be read after compilation@@The problem. If the problem persists, you can check the IDEA's log output to find out if there is any error information about the failed profile activation, and further troubleshoot the problem based on the error message.
