PaymentDetail1:
 - billPaymentNo: "201904171022507929513877465876"
  paymentAmount: 1000.00
  paymentMethod1: "ODD"
  paymentSuccessDate: 2019-04-17 13:00:00

转为json如下：

PaymentDetail1: [{billPaymentNo:'201904171022507929513877465876',paymentAmount: 1000, paymentMethod1: 'ODD',paymentSuccessDate: Wed Apr 17 2019 21:00:00 GMT+0800 (China Standard Time)}]

理解为：PaymentDetail1值为一个列表，列表中只有一个元素，该元素为一个字典，字典由多个键值对构成
