在yml中配置百度地图AK和地理编码

#百度地图 AK
baidu:
  ak: MKUZ0Oxzks86zaPstt
  url: http://api.map.baidu.com/geocoding/v3/?output=json&location=showLocation
  rurl: http://api.map.baidu.com/reverse_geocoding/v3/?output=json&coordtype=BD09&pois=1

创建返回地理位置信息实体类

    private static final Long serializableValue = 1L;


    /**
