Question

enter image description here我有一个如下所示的json模式，并且我想根据我已经写过allOf条件的B和C的值将定义加载到D和E中。并且我正在使用 json-schema-validator 在应用程序中进行json模式验证。

i）下面的模式始终以有效方式通过，因为allOf条件从未评估过，并且不是从定义中加载验证器属性，例如maxLenth，multipleOf。

ii）我怀疑我在错误的地方（根架构或子架构）进行了条件处理，并且尝试了将 all 的所有逻辑移到 subschema 级别（在B，C和D，E内部）

iii）我尝试执行https://json-schema.org/understanding-json-schema/reference/conditionals.html上提到的 allOf 示例，该示例也作为有效传递。为此，我确实在在线josn模式验证器http://json-schema-validator.herokuapp.com/上进行了验证，该验证器也使用相同的库 json-schema-validator。

iv）JsonSchemaFactory是否需要任何ValidationConfiguration来验证Draft7 jsonSchema条件，因为此 json-schema-validator 上的Defaultlibrary是DRAFT-4。

javaCode看起来像

@PostMapping("/sendMessage")
    public ProcessingReport sendMessage(@RequestBody SampleRequest request) throws IOException, ProcessingException {

        //step-1 writing request object into String
        String requestJson = objectMapper.writeValueAsString(request);

        //Step-2 getting jsonNode for requested json
        JsonNode dataNode = JsonLoader.fromString(requestJson);

        //step -3 creating jsonSchema factory(default)
        JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
        //validating requested jsonNode(dataNode) against SchemaNode(schema of request json,which is loaded from resources)
        ProcessingReport report = factory.getJsonSchema(schemaNode).validate(dataNode);


        //Processing report resulting the given json validation is successful or not
        if(!report.isSuccess()) {
            System.out.println(report);
        }
        return report;
    }

Answer 1

json-schema-validator仅支持草稿03和草稿04。在以后的草稿中添加了if / then / const。这些关键字会被忽略，从而导致您遇到无操作行为。

您有两种选择

选择另一个支持草案07的implementation
改为使用Implication Pattern。有点冗长，但结果是相同的。

jsonschema验证使用allof和其他if
