Eclipse RCP 程序获取程序路径

一、Rcp程序获取程序安装路径

 Stringpath=null;
 Locationlocation=Platform.getInstallLocation();
 if(location!=null){
 URLurl=location.getURL();
 path=url.getPath();
 }

二、获取Plug-in中的资源的绝对路径

 importjava.io.IOException;
 importjava.net.MalformedURLException;
 importjava.net.URL;

 importorg.eclipse.core.runtime.FileLocator;
 importorg.eclipse.core.runtime.Path;
 importorg.eclipse.core.runtime.Platform;
 importorg.osgi.framework.Bundle;

 publicclassTestGetFullPath{
 //filePath为资源的相对路径
 publicstaticStringgetFullPath(StringpluginId,StringfilePath){
 if(pluginId==null||filePath==null){
 thrownewIllegalArgumentException();
 }

 //ifthebundleisnotreadythenthereisnofile
 Bundlebundle=Platform.getBundle(pluginId);
 if(!isReady(bundle)){
 returnnull;
 }

 //lookforthefile(thiswillcheckboththepluginandfragment
 //folders
 URLfullPathString=find(bundle,filePath);
 if(fullPathString==null){
 try{
 fullPathString=newURL(filePath);
 }catch(MalformedURLExceptione){
 returnnull;
 }
 }

 if(fullPathString==null){
 returnnull;
 }
 try{
 fullPathString=FileLocator.toFileURL(fullPathString);
 }catch(IOExceptione){
 e.printStackTrace();
 }
 returnfullPathString.getPath();
 }

 publicstaticbooleanisReady(Bundlebundle){
 returnbundle!=null&&isReady(bundle.getState());
 }

 publicstaticbooleanisReady(intbundleState){
 return(bundleState&(Bundle.RESOLVED|Bundle.STARTING
 |Bundle.ACTIVE|Bundle.STOPPING))!=0;
 }

 publicstaticURLfind(Bundlebundle,Stringpath){
 if(bundle==null){
 returnnull;
 }
 returnFileLocator.find(bundle,newPath(path),null);
 }
 }
