【问题描述】：
我在将 Map 转换为 JSON 时遇到问题。在这里，我需要根据付款类型、渠道和货币将数据格式化为嵌套的 JSON。由于数据没有排序，我不确定如何在 JAVA 中实现这一点。
输入：
{by_status=COMPLETED, by_processingDate=2019-08-08, by_paymentType=REALTIME, by_channel=A, by_currency=SGD} count: 79129
{by_status=FAILED, by_processingDate=2019-08-08, by_paymentType=REALTIME, by_channel=B, by_currency=SGD} count: 2
{by_status=FAILED, by_processingDate=2019-08-08, by_paymentType=REALTIME, by_channel=A, by_currency=SGD} count: 79
{by_status=FAILED, by_processingDate=2019-08-10, by_paymentType=REALTIME, by_channel=A, by_currency=SGD} count: 3
{by_status=FAILED, by_processingDate=2019-08-08, by_paymentType=REMITTANCE, by_channel=B, by_currency=SGD} count: 3347
{by_status=FAILED, by_processingDate=2019-08-08, by_paymentType=false, by_channel=A, by_currency=SGD} count: 3
{by_status=PENDING, by_processingDate=2019-08-08, by_paymentType=REALTIME, by_channel=B, by_currency=SGD} count: 2
{by_status=PENDING, by_processingDate=2019-08-08, by_paymentType=REALTIME, by_channel=A, by_currency=SGD} count: 15
{by_status=PENDING, by_processingDate=2019-08-08, by_paymentType=REMITTANCE, by_channel=B, by_currency=SGD} count: 11654
{by_status=PENDING, by_processingDate=2019-08-08, by_paymentType=REMITTANCE, by_channel=B, by_currency=USD} count: 7
预期输出：
[
{
"COUNTRY": "SG",
"B": {
"REMITTANCE": [
{
"CURRENCY": "SGD",
"FAILED":3347,
"PENDING": 11654
},
{
"CURRENCY": "USD",
"PENDING": 7
}
],
"REALTIME": [
{
"CURRENCY": "SGD",
"FAILED":2,
"PENDING": 2
}
]
},
"A": {
"REALTIME": [
{
"CURRENCY": "SGD",
"COMPLETED": 79129,
"FAILED": 79,
"PENDING": 15
}
]
}
}
]
