java - 使用 json-schema-validator 评估 JSON 文件模式

Question

我有一个示例 JSON 文件，并且还提出了一个架构来使用以下 JSON 文件评估上述文件:

//[gcp_ingestion_parameters_schema.json]
{
...
    "properties": {
        "application": {
            "$ref": "#/definitions/application"
        },
        "ingestion": {
            "$ref": "#/definitions/ingestion"
        }
    },
    "definitions": {
        "applicaion": {
            "type": "object",
            "properties": {
                "project_id": {
                    "type": "string"
                },
                "path_to_json_key_file": {
                    "type": "string"
                }
            },
            "required": [
                "project_id",
                "path_to_json_key_file"
            ]
    },
 ...

我仍然不确定如何编写架构文件。在我的示例文件中，应用程序和摄取标签都应该出现一次，但摄取内的文件摄取映射可以出现一次或多次。

我编写了一些 java 代码来根据提供的 JSON 架构文件评估我的 JSON 文件(第一个文件)。

但我得到如下异常:线程“main”中的异常

com.github.fge.jsonschema.core.exceptions.ProcessingException: fatal: JSON Reference "#/definitions/appl
ication" cannot be resolved
    level: "fatal"
    schema: {"loadingURI":"#","pointer":"/properties/application"}
    ref: "#/definitions/application"

一些具有上述库工作经验的人可以回答我在此步骤中提出的问题吗？

正如所建议的，您的架构中有一个拼写错误，它应该低于

这与您提供的 JSON 完美配合。
