城市界面更新改造调研报告使用eclipse中的更新配置界面在eclipse中的众多特性中有一条可以自动更新的功能，我们可能在实际使用中也需要eclipse那样的更新功能，而eclipse提供了更新和管理插件的配置对话框，在这里我们可用发扬发扬"拿来主义"，直接拿过来用，过程很简单，步骤如下新建一个插件项目，然后打开plugin.xml文件，切换到extensions选项卡，增加"org.eclipse.ui.actionsets"扩展点，然后新建如下节点下面是整个plugin.xml文件内容我们要使这个扩展菜单项生效，必须要新建对应的action类来负责执行操作，先来看"查找并安装"对应的action类installwizardaction.javapackageupdateandinstall.actions;importorg.eclipse.jface.action.action;importorg.eclipse.jface.action.iaction;importorg.eclipse.jface.viewers.iselection;importorg.eclipse.swt.custom.busyindicator;importorg.eclipse.ui.iworkbenchwindow;importorg.eclipse.ui.iworkbenchwindowactiondelegate;importorg.eclipse.ui.platformui;importorg.eclipse.update.ui.updatemanagerui;publicclassinstallwizardactionextendsactionimplementsiworkbenchwindowactiondelegate{privateiworkbenchwindowwindow;publicinstallwizardaction{}publicvoiddispose{//todo自动生成方法存根}publicvoidinit（iworkbenchwindowwindow）{this.window=window;}publicvoidrun（iactionaction）{openinstaller（platformui.getworkbench.getactiveworkbenchwindow）;}publicvoidselectionchanged（iactionaction，iselectionselection）{//todo自动生成方法存根}privatevoidopeninstaller（finaliworkbenchwindowwindow）{busyindicator.showwhile（window.getshell.getdisplay，newrunnable{publicvoidrun{updatemanagerui.openinstaller（window.getshell）;}}）;}}我们通过这个类直接调用更新管理器中提供的api就行了"配置管理"对应的action类configurationmanageraction.javapackageupdateandinstall.actions;importorg.eclipse.jface.action.iaction;importorg.eclipse.jface.viewers.iselection;importorg.eclipse.swt.custom.busyindicator;importorg.eclipse.ui.iworkbenchwindow;importorg.eclipse.ui.iworkbenchwindowactiondelegate;importorg.eclipse.update.ui.updatemanagerui;publicclassconfigurationmanageractionimplementsiworkbenchwindowactiondelegate{privateiworkbenchwindowwindow;publicvoiddispose{//todo自动生成方法存根}publicvoidinit（iworkbenchwindowwindow）{this.window=window;}publicvoidrun（iactionaction）{busyindicator.showwhile（window.getshell.getdisplay，newrunnable{publicvoidrun{updatemanagerui.openconfigurationmanage
