特殊符號引起的JSON轉換異常
json格式如下
{"result":{"content":[{"createTime":1535212794000,"id":"8a5406e465713888016571d031e70000","resoucePoolId":"5e11323124e0444c90f2e42de05cd444","state":"available","usersasid":"6fb93a1ddf1b43b095067e0197614b05","vlanid":"6"},{"createTime":1535193428000,"id":"8a5406e46570a123016570a2dd1e0000","networkid":"33333333333333","resoucePoolId":"24","state":"available","usersasid":"6fb93a1ddf1b43b095067e0197614b05","vlanid":"3"}],"first":true,"last":true,"number":0,"numberOfElements":2,"pageable":{"offset":0,"pageNumber":0,"pageSize":10,"paged":true,"sort":{"sorted":true,"unsorted":false},"unpaged":false},"size":10,"sort":{"$ref":"$.result.pageable.sort"},"totalElements":2,"totalPages":1},"message":"ok","status":200}
反覆看了好遍，是符合json格式的，但用
JSONObject jsonObject1=JSONObject.parseObject(result);的時候卻報空值異常了
java.lang.NullPointerException

與之前的對比，發現有個特殊符號$，試著用
result=result.replace("$","s");
JSONObject jsonObject1=JSONObject.parseObject(result);
發現就可以了。
