Eclipse插件保存命令成功

Question

我需要实现一个插件来使每次使用保存文件时都会向服务器记录一些东西。 该文件可以是任何类型（html，js，css，java，py）。 我有以下内容：

package tstsave;
import org.eclipse.ui.IStartup;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.commands.ICommandService;
import org.eclipse.ui.plugin.AbstractUIPlugin;
import org.osgi.framework.BundleContext;

public class Activator extends AbstractUIPlugin implements IStartup {
    public static final String PLUGIN_ID = "tstsave"; //$NON-NLS-1$
    private static Activator plugin;

    public Activator() {
        Log.log("Activator()");
    }

    public void start(BundleContext context) throws Exception {
        super.start(context);
        ICommandService commandService = (ICommandService) PlatformUI.getWorkbench().getService(ICommandService.class);
        commandService.addExecutionListener(new SaveListener());
        plugin = this;
    }

    public void stop(BundleContext context) throws Exception {
        plugin = null;
        super.stop(context);
    }

    public static Activator getDefault() {
        return plugin;
    }

    @Override
    public void earlyStartup() {
        Log.log("earlyStartup()");
    }

}

我的听众

import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.core.commands.IExecutionListener;
import org.eclipse.core.commands.NotHandledException;

public class SaveListener implements IExecutionListener  {

    @Override
    public void notHandled(String arg0, NotHandledException arg1) {

    }

    @Override
    public void postExecuteFailure(String arg0, ExecutionException arg1) {

    }

    @Override
    public void postExecuteSuccess(String arg0, Object arg1) {
        System.out.println("test");
        Log.log("postExecuteSuccess");
    }

    @Override
    public void preExecute(String arg0, ExecutionEvent arg1) {

    }

}

简单的记录器

import java.io.BufferedWriter;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;

public class Log {
    public static void log(String message){
        Writer writer = null;
        try {
            writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("C:\\temp\\filename.txt"), "utf-8"));
            writer.write(message);
        } catch (IOException ex) {
          // report
        } finally {
           try {writer.close();} catch (Exception ex) {/*ignore*/}
        }
    }
}

该插件似乎无法正常工作，因此从未调用过。 有小费吗？

Answer 1

我不得不创建另一个类，还添加了org.eclipse.ui.startup扩展点。

import org.eclipse.ui.IStartup;

public class StartupClass implements IStartup {

@Override
public void earlyStartup() 
{

}
}

和plugin.xml代码

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>
   <extension point="org.eclipse.ui.startup">
         <startup class="myplugin.StartupClass" />
   </extension>

</plugin>
