JSONPath "deepScan属性访问，例如$..name" 抛出异常

[l99xl]

使用1.2.8版本，main方法中执行以下代码：
String text = "{\"a\":{\"b\":\"c\",\"g\":{\"e\":\"f\"}},\"d\":{\"a\":\"f\",\"h\":[\"s1\"]}} "; JSONObject jsonObject = JSONObject.parseObject(text); Object eval = JSONPath.eval(jsonObject, "$..a");

抛出异常
Exception in thread "main" com.alibaba.fastjson.JSONPathException: illeal jsonpath syntax. $..a

我刚测试过，新版本是好的，升级到最新版吧 https://github.com/alibaba/fastjson/releases/tag/1.2.31

果然如此。非常感谢！ 不过在使用的过程中又遇到了新的问题： String text = "{\"a\":{\"x\":\"y\"},\"b\":{\"x\":\"y\"}}"; JSONObject jsonObject = JSONObject.parseObject(text); System.out.println(jsonObject); String jsonpath = "$..x"; String value="y2"; JSONPath.set(jsonObject, jsonpath, value); System.out.println(jsonObject); 执行以上代码， 我期望的结果是：{"a":{"x":"y2"},"b":{"x":"y2"}} 但实际结果却是：{"a":{"x":"y"},"b":{"x":"y"},"x":"y2"} 同样的，text="{\"a\":{\"x\":[\"e1\",\"e2\"]},\"b\":{\"x\":[\"e1\",\"e2\"]}}" 时， 执行结果为{"a":{"x":["e1","e2"]},"b":{"x":["e1","e2"]},"x":"y"}，期望的结果依然是{"a":{"x":"y2"},"b":{"x":"y2"}} 所以，请问JSONPath是否有方法可以实现我预期的结果，即批量替换json对象及其子节点中多个相同key的值。
