gradle - 运行时无法在 build.gradle 中包含 JSON Schema 验证 json 文件

问题描述

我正在尝试使http://json-schema.org/draft-04/schema#在本地存储库中。但它无法在任何路径中找到引用的 JSON，无论是根目录、资源还是当前目录，或者直接在 jar 中。

由于这些是运行时异常，因此资源中的 json-schema.org/draft-04/schema.json 文件以及 jar 似乎不在打包的构建中。

有没有办法，我可以在 build.gradle 中的 JavaCompile 中定义来选择 json 文件

下面是代码片段

架构.json：

   {
    "$ref": "file://json-schema-draft-04-schema.json",
    "type": "object",
    "title": "Hyperledger Fabric Contract Definition JSON Schema",
    "required": [
        "info",
        "contracts"
    ],
    "properties": {
        "info": {
            "$ref": "#/definitions/info"
        },
        "contracts": {
            "type": "object",
            "patternProperties": {
                "^.*$": {
                    "$ref": "#/definitions/contract"
                }
            }
        },
        "components": {
            "$ref": "#/definitions/components"
        }
    },
    "definitions": {
        "info": {
            "type": "object",
            "description": "General information about the API.",
            "required": [
                "version",
                "title"
            ],
            "properties": {
                "title": {
                    "type": "string",
                    "description": "A unique and precise title of the API."
                },
                "version": {
                    "type": "string",
                    "description": "A semantic version number of the API."
                },
                "description": {
                    "type": "string",
                    "description": "A longer description of the API. Should be different from the title.  GitHub Flavored Markdown is allowed."
                },
                "termsOfService": {
                    "type": "string",
                    "description": "The terms of service for the API."
                },
                "contact": {
                    "$ref": "#/definitions/contact"
                },
                "license": {
                    "$ref": "#/definitions/license"
                }
            }
        },

参考json json-schema-draft-04-schema.json：

   {
    "id": "http://json-schema.org/draft-04/schema#",
    "description": "Core schema meta-schema",
    "definitions": {
        "schemaArray": {
            "type": "array",
            "minItems": 1,
            "items": { "$ref": "#" }
        },
        "positiveInteger": {
            "type": "integer",
            "minimum": 0
        },
        "positiveIntegerDefault0": {
            "allOf": [ { "$ref": "#/definitions/positiveInteger" }, { "default": 0 } ]
        },
        "simpleTypes": {
            "enum": [ "array", "boolean", "integer", "null", "number", "object", "string" ]
        },
        "stringArray": {
            "type": "array",
            "items": { "type": "string" },
            "minItems": 1,
            "uniqueItems": true
        }
    },
    "type": "object",
    "properties": {
        "id": {
            "type": "string"
        },
        "$schema": {

这两个文件都在一个可执行的 jar 中。我也尝试将参考 .json 文件放在项目的根目录中，但没有运气。也尝试使用 classpath://。没运气。

解决方案

这里有两个可能的问题。

首先，您假设您使用的库支持该file://协议。是否专门记录了您可以在正在使用的库中以这种方式引用本地文件？JSON Schema 本身不对协议支持做任何假设，也不知道自己是文件夹结构中的文件。

其次，您不能$ref在同一对象中与其他关键字一起使用。即使您的参考确实解决了，它也会使架构中的所有其他关键字被忽略。您需要使用allOf.
