有许多关于如何在同一个Json模式文件中使用$ id和$ ref的示例。但是我还没有找到任何示例来说明如何在多个模式文件中使用它。我在一个Spring Boot项目和mongoDB中工作。我的架构文件位于以下路径：

代码语言：javascript
复制
/resources/schemas/
             root_schema.json
             centros_schema.json

root_schema.json是一组建筑物(中心)，而centros_schema.json是我定义建筑物(中心)的位置。

我遵循了文档here。但我一直无法使其工作，并将centros_shema.json中的$id与root_schema中的$ref链接起来。看看有没有人能告诉我怎么做。

这是我的root_schema.json：

代码语言：javascript
复制
{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "type": "object",
    "properties": {
        "centros": {
            "type": "array",
            "items": [
                {
                    "$ref": "centros_schema.json"
                }
            ]
        }
    },
    "required": [
        "centros"
    ]
}

这是我的centros_schema.json：

代码语言：javascript
复制
{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "$id": "centros_schema.json",
    "type": "object",

这就是它抛给我的错误。我使用哪种路由并不重要。

JSON架构$ref解析使用URI解析过程。请注意，这些不是URL，并且与任何物理文件的位置不相关，也不是网络可寻址的。$id只是一个标识符。

URI不是网络定位符，只是一个标识符。如果模式是网络可寻址的，则不必从地址下载该模式

URL，并且实现不应假定它们应该执行

当他们遇到网络可寻址URI时进行网络操作。

https://datatracker.ietf.org/doc/html/draft-handrews-json-schema-01#section-8.3

在实践中，这意味着您必须将模式加载到实现中，以便它知道哪些标识符与哪些模式资源相关。

一些实现可能允许您从文件夹加载JSON文件，然后使用它们的JSON值来确定URI解析，但是这样的功能是特定于实现的。

您必须查看您正在使用的实现的文档，了解如何加载其他模式。

此外，$ref中使用的URI将根据当前作用域的架构资源的基URI进行解析。您应该为您的主架构定义一个$id，以便提供一个基本URI。可以把它想象成浏览器中的锚点链接。如果不能从模式资源建立基本URI，则根据URI解析协议由实现确定。

在学习时，最简单、最直接的引用方法是始终使用完整的URI作为引用。

如果一个模式中的$id是"$id": "http://ga4gh.org/schemas/discovery/search/definitions"，那么另一个文件中的$ref可能看起来像"$ref": "http://ga4gh.org/schemas/discovery/search/definitions#definitions/semver"。

您在问题中链接的文档目前正在重写中，我认为它将回答您在此主题上的所有问题。现在，我们将概述标识和引用模式的工作原理。

模式由非相对URI (https://example.com/path/to/schema或file:///path/to/schema)标识。引用($ref)可以是相对的，并根据文档的标识符进行解析，以获得标识模式的非相对URI。

如果架构的标识符是file:///path/to/schemas/root_schema.json，并且架构引用了centros_schema.json。引用解析为file:///path/to/schemas/centros_schema.json。

然而，并不是所有的模式都有标识符。如果您的模式没有标识符，而您的模式中有一个相对引用，则该引用不能解析为非相对URI来正确标识模式。centros_schema.json无法解析，因为它不是非相对URI。这就是你得到的“引用不能被解析”错误告诉你的。

一种解决方案是使您的$ref成为一个非相对URI，这样它就不需要标识符即可完全解析。

代码语言：javascript
复制
{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "type": "object",
    "properties": {
        "centros": {
            "type": "array",
            "items": [
                {
                    "$ref": "file:///path/to.schemas/centros_schema.json"
                }
            ]
        }
    },
    "required": [
        "centros"
    ]
}
代码语言：javascript
复制
{
    "$schema": "http://json-schema.org/draft-07/schema#",
    ... no $id needed for centros_schema.json
}

如果您正在使用的JSON Schema实现知道如何从文件系统获取file:// URI，那么这将会起作用。看起来就是这种情况，所以我将继续这个假设。

centros_schema.json模式不需要$id，因为在root_schema.json中用于引用它的非相对URI将成为该模式的标识符。

解决这个问题的另一种方法是为root_schema.json分配一个标识符。

代码语言：javascript
复制
{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "$id": "file:///path/to/schema/root_schema.json",
    "type": "object",
    "properties": {
        "centros": {
            "type": "array",
            "items": [
                {
                    "$ref": "centros_schema.json"
                }
            ]
        }
    },
    "required": [
        "centros"
    ]
}
代码语言：javascript
复制
{
    "$schema": "http://json-schema.org/draft-07/schema#",
    ... no $id needed for centros_schema.json
}

现在，$ref可以是相对的，并且仍然可以解析为标识centros_schema.json模式的非相对URI。

当然，这两种解决方案都要求您将文件系统路径硬编码到您的模式中，这可能会因为许多原因而出现问题。理想情况下，JSON Schema实现将首先使用用于获取root_schema.json的文件系统路径自动分配一个标识符。然后，您可以使用文件系统相对路径，而不必在任何地方分配$id。

如果JSON Schema实现不支持这一点，那么可以使用$id将https:// URI分配给每个模式，并使用这些URI标识/引用它们。

代码语言：javascript
复制
{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "$id": "https://example.com/path/to/schemas/root_schema.json",
    "type": "object",
    "properties": {
        "centros": {
            "type": "array",
            "items": [
                {
                    "$ref": "centros_schema.json"
                }
            ]
        }
    },
    "required": [
        "centros"
    ]
}
代码语言：javascript
复制
{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "$id": "https://example.com/path/to/schemas/centros_schema.json",
}

使用此方法时，在尝试使用模式验证实例之前，需要将这两个模式预加载到JSON模式实现的内部模式数据库中。这是如何完成的，这是特定于实现的，因此您必须查看正在使用的JSON Schema实现的文档。

我刚解决了这个问题。有一件事我是不明白的。我认为Json Schema的文档以及如何使用它是唯一需要记住的事情，因为它是一个“通用”的跨平台系统。但事实证明，它并不适用于所有的库。我正在使用这个依赖关系：

代码语言：javascript
复制
<dependency>
            <groupId>com.networknt</groupId>
            <artifactId>json-schema-validator</artifactId>
            <version>1.0.52</version>
        </dependency>

并且需要在uri的开头添加单词"classpath“或"resource”。因此，对我来说起作用的是删除$id并使用$ref，如下所示：

代码语言：javascript
复制
"$ref": "classpath:/schemas/centros_schema.json"

非常感谢你的帮助。这是非常有用的。
