问题描述
如何将 FieldDeclaration （类型：ASTNode）转换为 IField （类型：JavaElement）。是否可以从FieldDeclaration ASTNode获取绑定，就像node.resolveBinding（）一样，用于MethodDeclaration节点。
How can a FieldDeclaration (type: ASTNode) be converted to an IField (type: JavaElement). Is it possible to get the binding from the FieldDeclaration ASTNode, just like node.resolveBinding() as for MethodDeclaration node.
需要：我是访问具有公共常量的Class中的FieldDeclaration节点，并希望在项目中搜索该字段的引用。我使用的是JDT的SearchEngine。为此，我想创建一个搜索模式，如下所示：
Need : I am visiting a FieldDeclaration node in a Class having public constants, and want to search references for that field in the project. I am using JDT's SearchEngine for same. For this I want to create a search pattern as follows :
SearchPattern.createPattern(iField, IJavaSearchConstants.REFERENCES);
我已将此作为对我的，但没有得到相同答案。将其作为单独的问题发布。
I have asked this as a comment to one of my questions, but didn't get the answer for same. Posting it as separate question.
预先感谢答案。

使用您的方法，我可以按以下方式检索JavaElement
Using your approach i can retrieve the JavaElement as follows
List<VariableDeclarationFragment> fragments = node.fragments();
VariableDeclarationFragment fragment = fragments.get(0);
IJavaElement fieldElement = fragment.resolveBinding().getJavaElement();
如果我通过此IJavaElement而不是IField来创建搜索模式，它将返回相同的结果
If i am passing this IJavaElement to create the search pattern instead of the IField will it return the same result as those for an IField.
推荐答案
与往常一样，ASTView插件是您的朋友！ :-)在ASTView中，您可以看到该绑定可用于VariableDeclarationFragment，但不能用于FieldDeclaration。
As usual ASTView plugin is your friend! :-) In the ASTView you can see that binding is available for VariableDeclarationFragment but not for a FieldDeclaration.
从FieldDeclaration获取绑定
Getting the binding from FieldDeclaration
- 获取FieldDeclaration的碎片 =>现在，您有一堆VariableDeclarationFragment节点
- 调用VariableDeclarationFragment＃resolveBinding（）（this方法是从VariableDeclaration继承的）
