 [Java Open Source]Integrate Compass, Appfuse, DisplayTag Tutorial Part 2
软件技术

| Quickly you will find that, every time you run "test-web".
All data in db earsed, reload test-data and index data.
It is good news that we can have a clear index data for test.
But not at all ^^
Sometimes in our test, we need to create some test data at runtime.
We appreciate to index them too.
On the other hand, application admin will be happy that they can reindex by hand.
So, let us create index and delete index functions and test them ^^
All Codes could be download here
I remove lib, extra, docs folder to reduce size.
Step 1. Create test to delete index and create index.
1. Create Action named "CompassAction.java" under src\web, and add below codes
------ start here ------ package org.myapp.webapp.action;
import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.ActionForm;import org.apache.struts.action.ActionForward;import org.apache.struts.action.ActionMapping;import org.compass.core.Compass;import org.compass.gps.CompassGps;
/** * * * @struts.action name="compassForm" path="/compass" scope="request" * validate="false" parameter="method" input="mainMenu" * * @struts.action-forward name="list" path="/WEB-INF/pages/compassList.jsp" * */public final class CompassAction extends BaseAction { public ActionForward createIndex(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { System.out.println("Enter createIndex method"); CompassGps compassGps = (CompassGps) getBean("compassGps"); boolean isRun = compassGps.isRunning(); System.out.println("isRun : "+ isRun); if(!isRun){ compassGps.start(); } compassGps.index(); return mapping.findForward("list"); } public ActionForward deleteIndex(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { System.out.println("Enter deleteIndex method"); Compass compass = (Compass) getBean("compass"); CompassGps compassGps = (CompassGps) getBean("compassGps"); boolean isRun = compassGps.isRunning(); System.out.println("isRun : "+ isRun); if(isRun){ compassGps.stop(); } compass.getSearchEngineIndexManager().deleteIndex(); return mapping.findForward("list"); } public ActionForward unspecified(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { return createIndex(mapping, form, request, response); }
}
------ end here------ Well, what we done? ^^
In createIndex, we get compassGps, check if engine running, then index it.
In deleteIndex, compass, check if engine stop, then delete index. Note:Form and jsp is empty, since we will not use them at this time. 2. Create file named "CompassIndexActionTest.java" under test\web, and add below codes;
------ start here ------ package org.myapp.webapp.action;
public class CompassIndexActionTest extends BaseStrutsTestCase {
public CompassIndexActionTest(String name) { super(name); }
protected void setUp() throws Exception { super.setUp(); getMockRequest().setUserRole("admin"); } public void testDeleteIndex() throws Exception { setRequestPathInfo("/compass"); addRequestParameter("method", "deleteIndex"); actionPerform();
verifyForward("list"); verifyNoActionErrors(); } public void testCreateIndex() throws Exception { setRequestPathInfo("/compass"); addRequestParameter("method", "createIndex"); actionPerform();
verifyForward("list"); verifyNoActionErrors(); } }
------ end here------ Run "ant test-web -Dtestcase=CompassIndexActionTest" If all ok, you should get a beatiful "BUILD SUCCESSFUL" ^^ Check you compass index folder to see if newer index file generated. In my case, the location is C:\compass\myapp\index\user you should have _2.cfs deletable segments Launch luke to see the index results. Step2. Add ant task to create and delete index
Now admin is happy ^^, just give her a jsp that she can reindex data by hand. What about us? Let's create ant tasks for create and delete index 1. In test\web, create package "util" under "webapp" packgae Create file named "DeleteLuceneIndex.java", and add below codes ------ start here ------ package org.myapp.webapp.util;
import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.myapp.Constants;import org.compass.core.Compass;import org.compass.gps.CompassGps;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.util.ClassUtils;
public class DeleteLuceneIndex { protected final static Log log = LogFactory.getLog(DeleteLuceneIndex.class); public static void main(String[] args) throws Exception{ // hibernate & spring stuff String pkg = ClassUtils.classPackageAsResourcePath(Constants.class); String[] paths = {"classpath*:/" + pkg + "/dao/applicationContext-*.xml", "classpath*:/" + pkg + "/service/applicationContext-service.xml", "classpath*:META-INF/applicationContext-*.xml"}; ApplicationContext ctx = new ClassPathXmlApplicationContext(paths); Compass compass = (Compass) ctx.getBean("compass"); CompassGps compassGps = (CompassGps) ctx.getBean("compassGps"); boolean isRun = compassGps.isRunning(); System.out.println("isRun : "+ isRun); if(isRun){ compassGps.stop(); } System.out.println("Delete Index"); compass.getSearchEngineIndexManager().deleteIndex(); System.out.println("Delete Finish"); }}
------ end here------ 2. Create file named "PopulateLuceneIndex.java", and add below codes ------ start here ------ package org.myapp.webapp.util;
import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.myapp.Constants;import org.compass.core.Compass;import org.compass.gps.CompassGps;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.util.ClassUtils;
public class DeleteLuceneIndex { protected final static Log log = LogFactory.getLog(DeleteLuceneIndex.class); public static void main(String[] args) throws Exception{ // hibernate & spring stuff String pkg = ClassUtils.classPackageAsResourcePath(Constants.class); String[] paths = {"classpath*:/" + pkg + "/dao/applicationContext-*.xml", "classpath*:/" + pkg + "/service/applicationContext-service.xml", "classpath*:META-INF/applicationContext-*.xml"}; ApplicationContext ctx = new ClassPathXmlApplicationContext(paths); Compass compass = (Compass) ctx.getBean("compass"); CompassGps compassGps = (CompassGps) ctx.getBean("compassGps"); boolean isRun = compassGps.isRunning(); System.out.println("isRun : "+ isRun); if(isRun){ compassGps.stop(); } System.out.println("Delete Index"); compass.getSearchEngineIndexManager().deleteIndex(); System.out.println("Delete Finish"); }}
------ end here------ 3. Edit build.xml, add tasks below
------ start here ------ <!-- =================================================================== --> <!-- Convenience target to populate a lucene index --> <!-- =================================================================== --> <target name="create-lucene-index" description="Create the lucene index" depends="compile-web,delete-lucene-index,db-load"> <java classname="org.myapp.webapp.util.PopulateLuceneIndex"> <classpath> <path refid="web.test.classpath"/> <pathelement location="${build.dir}/web/classes"/> <pathelement location="${test.dir}/web/classes"/> <pathelement path="${java.class.path}"/> <pathelement path="src/web"/> </classpath> </java> </target> <!-- =================================================================== --> <!-- Convenience target to Delete a lucene index --> <!-- =================================================================== --> <target name="delete-lucene-index" description="Delete the lucene index" depends="compile-web"> <java classname="org.myapp.webapp.util.DeleteLuceneIndex"> <classpath> <path refid="web.test.classpath"/> <pathelement location="${build.dir}/web/classes"/> <pathelement location="${test.dir}/web/classes"/> <pathelement path="${java.class.path}"/> <pathelement path="src/web"/> </classpath> </java> </target> ------ end here------ 4. run "ant create-lucene-index" or "ant delete-lucene-index"
Well, now we have ant tasks for delete and create index ^^ Note:
Thomas Gaudin's tutorail present another option to create and delete index
Frankly, use <delete> in ant would be more simpler ^^
But since we have resourceLocations in applicationContext-service.xml
I choose to create classes to do it. Thanks Thomas Gaudin's tutorail, the original codes are referenced there. Summary
In this tutorail, we create actions and ant tasks that help us create and delete index. In next part, we will use annotation to simplify compass cpm file generation. |
