我想出了一个解决方案，以防万一其他人在寻找相同的东西：
public class JsonParser { private List<String> pathList; private String json; public JsonParser(String json) { this.json = json; this.pathList = new ArrayList<String>(); setJsonPaths(json); } public List<String> getPathList() { return this.pathList; } private void setJsonPaths(String json) { this.pathList = new ArrayList<String>(); JSonObject object = new JSonObject(json); String jsonPath = "$"; if(json != JSONObject.NULL) { readObject(object, jsonPath); } } private void readObject(JSonObject object, String jsonPath) { Iterator<String> keysItr = object.keys(); String parentPath = jsonPath; while(keysItr.hasNext()) { String key = keysItr.next(); Object value = object.get(key); jsonPath = parentPath + "." + key; if(value instanceof JSONArray) { readArray((JSONArray) value, jsonPath); } else if(value instanceof JSONObject) { readObject((JSONObject) value, jsonPath); } else { // is a value this.pathList.add(jsonPath); } } } private void readArray(JSonArray array, String jsonPath) { String parentPath = jsonPath; for(int i = 0; i < array.length(); i++) { Object value = array.get(i); jsonPath = parentPath + "[" + i + "]"; if(value instanceof JSONArray) { readArray((JSONArray) value, jsonPath); } else if(value instanceof JSONObject) { readObject((JSONObject) value, jsonPath); } else { // is a value this.pathList.add(jsonPath); } } }}
