java json架构验证相对路径不起作用（未找到URI） [英] java json schema validation relative path not working (URI not found)

问题描述

我正在查看来自github的2.2.6版本的验证器代码。
我没有更改回购中的任何代码 https://github.com /fge/json-schema-validator.git

I am looking at the 2.2.6 version of the validator code from github. I have not changed any code from the repo "https://github.com/fge/json-schema-validator.git"

当我针对引用第二个的json架构测试它时，我无法运行示例1模式文件（当我求助于硬编码的URI时，我可以使它工作）。

I am unable to get example 1 running when i test it against my json schema that references a second schema file (I can get it working when I resort to a hardcoded URI).

我只是重新命名了com.github.fge.jsonschema.examples.Example1.java来使用我的团队json架构和json文件。
我已经构建了项目并将我的json模式文件复制到json-schema-validator\bin\com\github\fge\jsonschema \ examples中（全部在同一个文件夹中，类似于fstab示例）

I have simply repointed the "com.github.fge.jsonschema.examples.Example1.java" to use my teams json schema and json files. I have built the project and copied my json schema files into "json-schema-validator\bin\com\github\fge\jsonschema\examples" (All in the same folder, similar to fstab examples)

附上顶级部分，

               },
                "MovingWindow": {
                    "description": "Is this an moving window measure?",
                    "type": "boolean"
                }
            },
            "minItems": 1,
            "uniqueItems": true
        },
        "RealTimeProfile": {
            "$ref": "rtp.json#"
        }
    },
    "required": [
        "MeasureTemplateId",
        "MeasureInstanceId",

但是我无法获得较低级别的读数，第二个模式文件（rtp.json）被识别出来&工作正常。
我看到以下错误：

but I am unable to get the reading of the lower level, 2nd schema file ("rtp.json") to be recognised & work correctly. I am seeing the below error:

线程main中的异常com.github.fge.jsonschema.core.exceptions.ProcessingException：fatal：URI rtp.json＃不是绝对
级别：致命
uri：rtp.json＃

Exception in thread "main" com.github.fge.jsonschema.core.exceptions.ProcessingException: fatal: URI "rtp.json#" is not absolute level: "fatal" uri: "rtp.json#"

我的代码片段：

File jsonFile = new File("CumulativeCountBad.json");
File jsonSchemaFile = new File("main.json");


JsonNode good = JsonLoader.fromFile(jsonFile);
JsonNode mainSchema = JsonLoader.fromFile(jsonSchemaFile);

final JsonSchemaFactory factory = JsonSchemaFactory.byDefault();

final JsonSchema schema = factory.getJsonSchema(mainSchema);

ProcessingReport report;

report = schema.validate(good);
System.out.println("good: " + report);

我的问题似乎与下面的问题相似，但是当我设置时，我似乎无法得到运行的东西e引用：
$ ref：rtp.json＃

My issue seems similar to the following issue but i don't seem to be able to gett the thing running when i set the reference to: "$ref": "rtp.json#"

任何帮助表示赞赏。
PS - 我是一个java新手，道歉，如果有明显的东西，我已经省了
谢谢

Any help appreciated. PS - I am a java newbie, apologies if there is something obvious that i have ommited Thanks

推荐答案

<问题是您加载JSON然后将其转换为架构。并且您的架构在id中没有绝对URI。因此，它无法工作。

The problem is that you load the JSON then turn it into a schema. And your schema does not have an absolute URI in "id". So, it cannot work.

您希望使用绝对URI来加载它们。由于您最初使用的是文件（注意，使用Java 7+，您确实希望使用java.nio.file），您可以使用以下方法获取绝对URI： / p>

You want to use an absolute URI to load them. Since you originally use a File (note, with Java 7+ you really want to use java.nio.file instead), you can obtain an absolute URI to it with:

final File jsonSchemaFile = new File("main.json");
final URI uri = jsonSchemaFile.toURI();

然后加载架构：

final JsonSchema schema = factory.getJsonSchema(uri.toString());
