Liferay Enterprise Version License analysis

In Liferay Enterprise, the use and control of license is very exquisite, because the lincense determines the use of products and the use of the term, we are now to in-depth analysis of the license.

Deployment of License:

First of all, back to listener, see http://supercharles888.blog.51cto.com/609344/907286 Blog said, in the Liferay mainservlet startup process, when dealing with the global startup event , it will register all the Antodeploylistener, of which Licenseautodeploylistener is also ranked:

01.auto.deploy.listeners=\
Com.liferay.portal.deploy.auto.osgiautodeploylistener,\
03. Com.liferay.portal.deploy.auto.extautodeploylistener,\
04. Com.liferay.portal.deploy.auto.hookautodeploylistener,\
05. Com.liferay.portal.deploy.auto.layouttemplateautodeploylistener,\
06. Com.liferay.portal.deploy.auto.liferaypackageautodeploylistener,\
07. Com.liferay.portal.deploy.auto.portletautodeploylistener,\
08. Com.liferay.portal.deploy.auto.themeautodeploylistener,\
09. Com.liferay.portal.deploy.auto.webautodeploylistener,\
10. Com.liferay.portal.deploy.auto.exploded.tomcat.hookexplodedtomcatlistener,\
11. Com.liferay.portal.deploy.auto.exploded.tomcat.layouttemplateexplodedtomcatlistener,\
12. Com.liferay.portal.deploy.auto.exploded.tomcat.portletexplodedtomcatlistener,\
13. Com.liferay.portal.license.deploy.auto.LicenseAutoDeployListener, Com.liferay.portal.deploy.auto.exploded.tomcat.ThemeExplodedTomcatListener

So, when we first put the license file in the $liferay_home/deploy directory, it triggers the licenseautodeploylistener to respond, and it implements the Autodeploylistener interface, So putting the license file into the Deploy directory triggers its Deploy method:

public void Deploy (File paramfile, String paramstring) 
 { 
   if (a.isdebugenabled ()) 
     A.debug ("invoking deploy For "+ Paramfile.getpath ()); 
   String str1 = fileutil.getextension (Paramfile.getname ()); 
   if (!str1.equals ("xml")) return 
     ; 
   Try
   { 
     String str2 = Fileutil.read (paramfile); 
     Document localdocument = Saxreaderutil.read (str2); 
     Element localelement = Localdocument.getrootelement (); 
     String STR3 = Localelement.getname (); 
     if (!str3.equals ("license")) return 
       ; 
   catch (Exception localexception) 
   {return 
     ; 
   } 
   if (a.isinfoenabled ()) 
     a.info ("Copying license for" + Paramfile.getpath ()); 
   This.b.autodeploy (Paramfile, paramstring); 
 }

From here we can see that it's 05-07 lines first to check whether the extension of the license file is XML. The 第10-13 Guild then uses Saxreadutil to read the file, and line 14th determines whether the root element is license. Then print out a line of information on line 22 (because the info level of the default log is open, so we can see this line of log):

06:25:14,380 INFO [licenseautodeploylistener:?] Copying license for D:\Liferay_Cluster_Enterprise\Node1\liferay-portal-tomcat-6.1.10-ee-ga1\ Liferay-portal-6.1.10-ee-ga1\deploy\license-portaldevelopment-developer-6.1-triallicenses.xml

Finally, line 23rd it calls the Autodeploy method for deployment, and we continue to follow up.

This b is an example of Licenseautodeployer, which completes the specific deployment of license:

public class Licenseautodeployer extends a 
  implements Autodeployer 
{public 
  void Autodeploy (File paramfile , String paramstring) 
  { 
    try
    { 
      THIS.A = Fileutil.read (paramfile); 
      A (); 
    } 
    ...
  } 
}
