介紹 本文介紹如何給Eclipse自帶的tomcat插件添加一些功能。

右鍵菜單擴展 添加擴展點 org.eclipse.ui.popupMenus [codesyntax lang="xml"]

id="org.eclipse.jst.server.tomcat.ui.serveractions" objectClass="org.eclipse.wst.server.core.IServer">

enablesFor="1" id="surenpi.com.dev.debugger.tomcat.openserverdiraction"

label="Open Deploy Directory">

id="org.eclipse.jst.server.tomcat.ui.serveractions" objectClass="org.eclipse.wst.server.ui.internal.view.servers.ModuleServer">

enablesFor="1" id="surenpi.com.dev.debugger.tomcat.openmodulediraction"

label="Open Deploy Directory">

[/codesyntax] 我們實現的功能是通過右鍵菜單打開tomcat下部署的項目： [codesyntax lang="java"]

public class OpenDirAction implements IObjectActionDelegate {

private IServer selectedServer;

private IModule selectedModule;

@Override

public void run(IAction action) {

if(selectedServer == null) {

return;

}

IPath targetPath = null;

try {

Class> clazz = Class.forName("org.eclipse.jst.server.tomcat.core.internal.TomcatServerBehaviour");

TomcatServerBehaviour behaviour = (TomcatServerBehaviour) selectedServer.loadAdapter(clazz, null);

if(selectedModule != null) {

} else {

}

} catch (ClassNotFoundException e) {

e.printStackTrace();

}

if(targetPath != null) {

File file = targetPath.toFile();

if(Desktop.isDesktopSupported()) {

try {

Desktop.getDesktop().open(file);

} catch (IOException e) {

e.printStackTrace();

}

}

}

}

@Override

public void selectionChanged(IAction action, ISelection selection) {

if ((!selection.isEmpty()) && ((selection instanceof IStructuredSelection))) {

Object obj = ((IStructuredSelection) selection).getFirstElement();

if ((obj instanceof IServer)) {

this.selectedServer = ((IServer) obj);

} else if ((obj instanceof IServerModule)) {

IServerModule sm = (IServerModule) obj;

IModule[] module = sm.getModule();

this.selectedModule = module[(module.length - 1)];

if (this.selectedModule != null)

this.selectedServer = sm.getServer();

}

}

}

@Override

public void setActivePart(IAction action, IWorkbenchPart targetPart) {

}

} [/codesyntax]

視圖工具欄擴展 添加擴展點 org.eclipse.ui.viewActions [codesyntax lang="xml"]

point="org.eclipse.ui.viewActions">

targetID="org.eclipse.wst.server.ui.ServersView">

label="Open Server Directory"

menubarPath="additions"

toolbarPath="additions"

icon="icons/explore.png"

tooltip="Open Server Directory"

class="surenpi.com.dev.explore.tomcat.OpenTomcatDir"

enablesFor="1">

[/codesyntax] 實現類與上面的OpenDirAction相同，只是要實現接口

org.

eclipse.

ui.IViewActionDelegate
