在 Eclipse RCP 插件开发中，获取编辑区（Editor）及其内容、判断当前活跃的编辑器，需要使用 Eclipse Platform 提供的 API，特别是 IWorkbench, IWorkbenchWindow, IWorkbenchPage, IEditorPart 等接口。
java
package com.xu.click1.handlers;
import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.jface.text.IDocument;
import org.eclipse.ui.IEditorPart;
import org.eclipse.ui.IWorkbenchPage;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.texteditor.IDocumentProvider;
import org.eclipse.ui.texteditor.ITextEditor;
public class SampleHandler extends AbstractHandler {
@Override
public Object execute(ExecutionEvent event) throws ExecutionException {
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IEditorPart part = page.getActiveEditor();
if (part instanceof ITextEditor) {
ITextEditor editor = (ITextEditor) part;
IDocumentProvider provider = editor.getDocumentProvider();
IDocument document = provider.getDocument(editor.getEditorInput());
System.out.println(String.format("%s:%s", editor.getTitle(), document.get()));
}
return null;
}
}2 获取全部编辑器

public class SampleHandler extends AbstractHandler {
@Override
public Object execute(ExecutionEvent event) throws ExecutionException {
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
for (IEditorReference ref : page.getEditorReferences()) {
IEditorPart editor = ref.getEditor(false);
if (null == editor) {
System.out.println(String.format("%s未被编辑", ref.getTitle()));
continue;
}
System.out.println(String.format("%s正在编辑:%s", ref.getTitle(), getEditContent(editor)));
}
return null;
}
private String getEditContent(IEditorPart part) {
if (part instanceof ITextEditor) {
ITextEditor editor = (ITextEditor) part;
IDocumentProvider provider = editor.getDocumentProvider();
IDocument document = provider.getDocument(editor.getEditorInput());
return document.get();
}
return null;
}
