spring1.X升级到spring2.X导致时间戳string无法自动转化成long类型

报错提示：

JSON parse error: Cannot deserialize value of type `java.lang.Long` from String "2021-12-24 15:20:45": not a valid Long value; nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.lang.Long` from String "2021-12-24 15:20:45": not a valid Long valuen at [Source: (PushbackInputStream); line: 1, column: 153] (through reference chain: com.sankuai.map.facade.console.model.ReportModel["occurTime"])","resultList":null}

在定义的接受参数的原来model里面是这样定义的：
private Long occurTime;
private Long occurTimeEnd;
为了最小化改动代码，把原来的参数接收类型从model转化成JSONObject。
