使用allof和complex if else进行jsonschema验证

Question

在这里输入image description我有一个如下所示的json模式，我希望根据B和C的值将定义加载到D和E中，为此我已经编写了所有的条件。我使用json-schema-validator在应用程序中进行json模式验证。

{
      "$schema": "http://json-schema.org/draft-07/schema#",
      "type": "object",
      "required": [
        "A",
        "B",
        "C",
        "D",
        "E"
      ],
      "properties": {
        "A": {
          "type": "string"
        },
        "B": {
          "type": "string",
          "enum": ["TEST1","TEST2"]
        },
        "C": {
          "type": "string",
          "enum": ["TEST3","TEST4"]
        },
        "D": {
          "type": "object"
        },
        "E": {
          "type": "object"
        }
      },
      "allOf": [
        {
          "if": {
            "properties": { "B": { "const": "TEST1" } }
          },
          "then": {
            "properties": { "D": {  "$ref": "#/definitions/test" } }
          }
        },
        {
          "if": {
            "properties": { "B": { "const": "TEST2" } }
          },
          "then": {
            "properties": { "D": {  "$ref": "#/definitions/testTwo" } }
          }
        },
        {
          "if": {
            "properties": { "C": { "const": "TEST3" } }
          },
          "then": {
            "properties": { "E": {  "$ref": "#/definitions/testThree" } }
          }
        },
        {
          "if": {
            "properties": { "C": { "const": "TEST4" } }
          },
          "then": {
            "properties": { "E": {  "$ref": "#/definitions/test4" } }
          }
        }
      ],

      "definitions": {
       "testOne":{"type":"object"},
       "testTwo":{"type":"object"},
       "testThree":{"type":"object"},
       "testFour":{"type":"object"}
        }
    }

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只支持draft-03和draft-04。如果/，则/常量将添加到以后的草稿中。这些关键字会被忽略，从而导致您正在经历的无操作行为。

你有两个选择

1. 选择支持Draft-07的其他实现
2. 改为使用蕴涵模式。有点冗长，但结果是一样的。
