Package com.randomnoun.common.servlet

Class VersionServlet

java.lang.Object
javax.servlet.GenericServlet
javax.servlet.http.HttpServlet
com.randomnoun.common.servlet.VersionServlet
All Implemented Interfaces:
Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
public class VersionServlet extends javax.servlet.http.HttpServlet
Reads the contents of the build.properties file in the current application and sends it to the browser in a variety of forms. Probably JSON for starters.

The properties file must be located on the classpath at the location "/build.properties".

For this to work, the application needs to have been built through maven (and possibly bamboo), and there should be a build.properties file in the application being created, with the contents: 

  bamboo.buildKey=${bambooBuildKey}
        bamboo.buildNumber=${bambooBuildNumber}
        bamboo.buildPlanName=${bambooBuildPlanName}
        bamboo.buildTimeStamp=${bambooBuildTimeStamp}
        bamboo.buildForceCleanCheckout=${bambooForceCleanCheckout}
        bamboo.custom.cvs.last.update.time=${bambooCustomCvsLastUpdateTime}
        bamboo.custom.cvs.last.update.time.label=${bambooCustomCvsLastUpdateTimeLabel}
        
        maven.pom.name=${pom.name}
    maven.pom.version=${pom.version}
    maven.pom.groupId=${pom.groupId}
    maven.pom.artifactId=${pom.artifactId}
and the bamboo plan should have the following in the bamboo plan's stage's job's task's maven goal specification: 
  "-DbambooBuildKey=${bamboo.buildKey}" 
    "-DbambooBuildNumber=${bamboo.buildNumber}" 
    "-DbambooBuildPlanName=${bamboo.buildPlanName}" 
    "-DbambooBuildTimeStamp=${bamboo.buildTimeStamp}" 
    "-DbambooBuildForceCleanCheckout=${bamboo.buildForceCleanCheckout}" 
    "-DbambooCustomCvsLastUpdateTime=${bamboo.custom.cvs.last.update.time}" 
    "-DbambooCustomCvsLastUpdateTimeLabel=${bamboo.custom.cvs.last.update.time.label}" 
    -DuniqueVersion=false

This script will also look for a build.properties file in /etc/build.properties; this should exist on docker containers built by bamboo. If this exists, it is also included in the JSON output under the "/etc/build.properties" key.
