Access system version from pom.xml into JSP (Maven + Spring)

I'm trying to access the version of my system (defined into pom.xml) from a JSP. It's the login screen, so no action was called before.

Is there a way to Spring read the version number from my pom and put it into request / session?

Thanks a lot for the attention!

You can perform resource filtering with Maven. Given the following in pom.xml

<properties>
    <system.version>1.2.3.4</system.version>
</properties>

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

any file in src/main/resources with a placeholder ${some.property}, where some.property resolves to a property in the pom.xml, will be replaced by the value of that property. For example, if you had a property file globals.properties like

system.version=${system.version}

Maven would filter the file and change it to

system.version=1.2.3.4

You can then have Spring inject that property with a PropertySourcesPlaceholderConfigurer and @Value.
