如何在Intellij Idea中编写对重复注释的自定义检查？

import com.intellij.codeInspection.*;
import com.intellij.psi.*;

public class DuplicateCommentInspection extends LocalInspectionTool {

    @Override
    public ProblemDescriptor[] checkFile(PsiFile file, InspectionManager manager, boolean isOnTheFly) {
        // 获取文件中的所有注释
        PsiComment[] comments = PsiTreeUtil.getChildrenOfType(file, PsiComment.class);

        // 存储重复的注释内容
        Set<String> duplicateComments = new HashSet<>();
        // 存储重复的注释行号
        Set<Integer> duplicateLines = new HashSet<>();

        // 遍历所有注释
        for (PsiComment comment : comments) {
            String commentText = comment.getText();
            int lineNumber = getLineNumber(comment);

            // 如果注释内容已经存在，说明是重复的注释
            if (duplicateComments.contains(commentText)) {
                duplicateLines.add(lineNumber);
            } else {
                duplicateComments.add(commentText);
            }
        }

        // 创建问题描述
        List<ProblemDescriptor> descriptors = new ArrayList<>();
        for (int lineNumber : duplicateLines) {
            PsiElement element = file.findElementAt(file.getLineStartOffset(lineNumber));
            descriptors.add(manager.createProblemDescriptor(element, "Duplicate comment", (LocalQuickFix) null, ProblemHighlightType.GENERIC_ERROR_OR_WARNING));
        }

        return descriptors.toArray(ProblemDescriptor.EMPTY_ARRAY);
    }

    private int getLineNumber(PsiElement element) {
        Document document = PsiDocumentManager.getInstance(element.getProject()).getDocument(element.getContainingFile());
        return document.getLineNumber(element.getTextOffset());
    }
}
