java - IntellijIdea 插件开发 : Navigate to the source file of a given class in the text editor

Question

假设我有一个像这样的类名:

org.myPackage.MyClass

我想在文本编辑器中导航到该类的源文件。到目前为止，我知道如何在编辑器中打开文件:

FileEditorManager fileEditorManager = FileEditorManager.getInstance(project);
VirtualFile vf = LocalFileSystem.getInstance().findFileByPath(myPath);
fileEditorManager.openFile(vf, true, true);

我也知道如何获取模块的源根目录，所以目前我所做的是将 myPath 设置为如下内容:

myPath = mainModuleSourceRoot + substituteDotsForSlash("org.myPackage.MyClass")

但是我想知道是否有更多“面向 IntellijIdea-Plugin”(更简单，也许更健壮)的方法来打开给定类的源文件。

Answer 1

我可以这样做:

    GlobalSearchScope scope = GlobalSearchScope.allScope(project);
    PsiClass psiClass = JavaPsiFacade.getInstance(project).findClass("org.myPackage.MyClass", scope);

    if ( psiClass != null ) {
        FileEditorManager fileEditorManager = FileEditorManager.getInstance(project);
        fileEditorManager.openFile(psiClass.getContainingFile().getVirtualFile(), true, true);
    } else {
        //handle the class not found
    }

编辑后的答案

我终于做了类似的事情:

    GlobalSearchScope scope = GlobalSearchScope.allScope(project);
    PsiClass psiClass = JavaPsiFacade.getInstance(project).findClass(className, scope);

    if (psiClass != null) {
        FileEditorManager fileEditorManager = FileEditorManager.getInstance(project);
        //Open the file containing the class
        VirtualFile vf = psiClass.getContainingFile().getVirtualFile();
        //Jump there
        new OpenFileDescriptor(project, vf, 1, 0).navigateInEditor(project, false);
    } else {
        //Handle file not found here....
        return;
    }
