背景：java 8日期api,在接口级别的入参、出参，原始结果看起来简直头疼，故做全局转化处理
例：拿LocalDate 举例，对于一个 日期 LocalDate.of(2019,9,15)，返回类型为 LocalDate， 原始结果如下：
{
"year": 2019,
"month": "SEPTEMBER",
"monthValue": 9,
"chronology": {
"id": "ISO",
"calendarType": "iso8601"
},
"dayOfMonth": 15,
"dayOfWeek": "SUNDAY",
"era": "CE",
"dayOfYear": 258,
"leapYear": false
}

经过全局处理（类文件见下列代码）后，同等条件，返回结果如下：
