Object转HashMap

JSONObject.parseObject(JSONObject.toJSONString(object), new TypeReference<HashMap<String, Object>>(){});

Object 转 List

JSONObject.parseArray(JSONObject.toJSONString(object), Entity.class)

HashMap 转 Entity

JSON.parseObject(JSON.toJSONString(hashmap), Entity.class);

Xml字符串递归转 Map

XML转换的时候, 格式特殊字符有诸多报错.
