公司要我写个eclipse插件获取编辑器的输入，我是这么做的：新建hello world的plugin-in project,重写SampleAction的run方法：
public void run(IAction action) {
//取得工作台
IWorkbench workbench = PlatformUI.getWorkbench();
//取得工作台窗口
IWorkbenchWindow window = workbench.getActiveWorkbenchWindow();
//取得工作台页面
IWorkbenchPage page = window.getActivePage();
//取得当前处于活动状态的编辑器窗口
IEditorPart part = page.getActiveEditor();
IEditorInput input = part.getEditorInput();
IDocument document;
document = ((ITextEditor)part).getDocumentProvider().getDocument(input);
}
上述代码在最后一行报异常：
java.lang.ClassCastException: org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitEditor cannot be cast to org.eclipse.ui.texteditor.ITextEditor
at t1.actions.SampleAction.run(SampleAction.java:57)
我查看了文档，CompilationUnitEditor是实现了ITextEditor接口的，那是哪里出错了？！ ps:本人做c的，初识java一周...
大家帮我看看啊 再搞不出要被骂了...
------解决方案--------------------
IEditorReference[] refers=PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getEditorReferences();
for(IEditorReference refer:refers){
IEditorPart part=refer.getEditor(false);
if(part instanceof ITextEditor){
\\...
}
}
取IEditorPart的方式改下试试
