Java编译器树API : Get fully qualified superclass name

Question

我正在尝试获取 ClassTree-Object 的父类(super class)的完全限定名称。目前我正在使用 toString() 方法:

public class ClassScanner extends TreePathScanner<Object, Trees> {

    @Override
    public Object visitClass(ClassTree ct, Trees trees) {
        TreePath currentPath = getCurrentPath();
        TypeElement typeElement = (TypeElement) trees.getElement(currentPath);
        String s = typeElement.getSuperclass().toString();
        System.out.println(s);
        return super.visitClass(ct, trees);
    }
}

但这似乎并不是一种面向 future 的方法。我还必须自己提取名称、包、通用类型……。有替代方案吗？

谢谢

怎么样

    Tree extendsClassTree = classTree.getExtendsClause();
    if (extendsClassTree != null) {
        superClassName = extendsClassTree.toString();
    } else {
        superClassName = "java.lang.Object";
    }
