Apache nifi Nifi使用jolt脚本将json转换为自定义json

我有类似的

{
“错误\消息\ 1”：“缺少\字段\ 1”，
“错误消息\u 2”：“缺少\u字段\u 2”，
错误消息\u 3:“缺少\u字段\u 3”
}

使用本规范：

我们正在创建有效负载

数组

，并将所有

错误消息*

键保留在有效负载数组中

[{
    "operation": "shift",
    "spec": {
        "error_message_1": "payloads[0].error_message_1",
        "error_message_2": "payloads[0].error_message_2",
        "error_message_3": "payloads[0].error_message_3"
    }
}, {
    "operation": "default",
    "spec": {
      "timestamp":"$timestmap",
        "source":"nifi"
    }
}]

输出：

{
    "payloads": [{
        "error_message_1": "missing_field_1",
        "error_message_2": "missing_field_2",
        "error_message_3": "missing_field_3"
    }],
    "source": "nifi",
    "timestamp": "2018-10-30 08:51:16.572"
}

此外，如果需要

timestamp

键的timestamp值，请使用以下规范：

[{
    "operation": "shift",
    "spec": {
        "error_message_1": "payloads[0].error_message_1",
        "error_message_2": "payloads[0].error_message_2",
        "error_message_3": "payloads[0].error_message_3"
    }
}, {
    "operation": "default",
    "spec": {
      "timestamp":"${now():format('yyyy-MM-dd HH:mm:ss.SSS')}",
        "source":"nifi"
    }
}]

输出：

{
    "payloads": [{
        "error_message_1": "missing_field_1",
        "error_message_2": "missing_field_2",
        "error_message_3": "missing_field_3"
    }],
    "source": "nifi",
    "timestamp": "2018-10-30 08:51:16.572"
}

}, {
    "operation": "default",
    "spec": {
      "timestamp":"$timestmap",
        "source":"nifi"

输出：
