2 插件控制

package com.xu.work.tool2;import org.eclipse.ui.plugin.AbstractUIPlugin;
import org.osgi.framework.BundleContext;/*** 插件激活器类，控制插件的生命周期*/
public class Activator extends AbstractUIPlugin {/*** 插件ID常量，通常与MANIFEST.MF中的Bundle-SymbolicName一致*/public static final String PLUGIN_ID = "com.xu.work.tool2"; //$NON-NLS-1$/*** 单例实例引用*/private static Activator plugin;/*** 构造函数*/public Activator() {}/*** 插件启动时调用*/@Overridepublic void start(BundleContext context) throws Exception {super.start(context);plugin = this;// 在这里注册监听器、服务、加载配置等}/*** 插件停止时调用*/@Overridepublic void stop(BundleContext context) throws Exception {plugin = null;super.stop(context);}/*** 返回此插件的共享实例** @return 共享实例*/public static Activator getDefault() {return plugin;}}
