[原]Eclipse RCP 程序获取程序路径

一、Rcp程序获取程序安装路径

String path = null;
Location location = Platform.getInstallLocation();
if (location != null) {
    URL url = location.getURL();
    path = url.getPath();
}

 

二、获取Plug-in中的资源的绝对路径

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;

import org.eclipse.core.runtime.FileLocator;
import org.eclipse.core.runtime.Path;
import org.eclipse.core.runtime.Platform;
import org.osgi.framework.Bundle;

public class TestGetFullPath {
        //filePath 为资源的相对路径
    public static String getFullPath(String pluginId, String filePath) {
        if (pluginId == null || filePath == null) {
            throw new IllegalArgumentException();
        }

        // if the bundle is not ready then there is no file
        Bundle bundle = Platform.getBundle(pluginId);
        if (!isReady(bundle)) {
            return null;
        }

        // look for the file (this will check both the plugin and fragment
        // folders
        URL fullPathString = find(bundle, filePath);
        if (fullPathString == null) {
            try {
                fullPathString = new URL(filePath);
            } catch (MalformedURLException e) {
                return null;
            }
        }

        if (fullPathString == null) {
            return null;
        }
        try {
            fullPathString = FileLocator.toFileURL(fullPathString);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return fullPathString.getPath();
    }

    public static boolean isReady(Bundle bundle) {
        return bundle != null && isReady(bundle.getState());
    }

    public static boolean isReady(int bundleState) {
        return (bundleState & (Bundle.RESOLVED | Bundle.STARTING
                | Bundle.ACTIVE | Bundle.STOPPING)) != 0;
    }

    public static URL find(Bundle bundle, String path) {
        if (bundle == null) {
            return null;
        }
        return FileLocator.find(bundle, new Path(path), null);
    }
}
