使用Everit JSON Schema Validator解析模式异常时返回JSON对象数组

我目前正在使用JSON Schema Validator和Gson一起处理异常并验证对API的json请求。

验证程序在将请求与架构进行比较时可以返回多个异常。来自存储库的示例是:

try {
  schema.validate(rectangleMultipleFailures);
}
catch (ValidationException e) {
  System.out.println(e.getMessage());
  e.getCausingExceptions().stream()
      .map(ValidationException::getMessage)
      .forEach(System.out::println);
}

try catch的实现(很明显错过了):

try (InputStream inputStream = this.getClass().getResourceAsStream("SupplierSchemaIncoming.json")) {
    JSONObject rawSchema = new JSONObject(new JSONTokener(inputStream));
    Schema schema = SchemaLoader.load(rawSchema);
    // Throws a ValidationException if requestJson is invalid:
    schema.validate(new JSONObject(requestJson));
}
catch (ValidationException ve) {
    System.out.println(ve.toJSON().toString());
}

如上所示,一个选项是将所有错误作为单个JSON返回。

{
    "pointerToViolation": "#",
    "causingExceptions": [{
        "pointerToViolation": "#/name",
        "keyword": "type",
        "message": "expected type: String, found: Integer"
    }, {
        "pointerToViolation": "#/type",
        "keyword": "type",
        "message": "expected type: String, found: Integer"
    }],
    "message": "2 schema violations found"
}

但是,我很难理解如何获取异常以返回SchemaError个对象(下面),我可以解析它,但是我想要它。

package domainObjects;

import com.google.gson.annotations.Expose;

public class SchemaError {
    @Expose
    String pointerToViolation;

    @Expose
    String keyword;

    @Expose
    String message;

    public SchemaError() {}

    public String getPointerToViolation() {
        return pointerToViolation;
    }

    public void setPointerToViolation(String pointerToViolation) {
        this.pointerToViolation = pointerToViolation;
    }

    public String getKeyword() {
        return keyword;
    }

    public void setKeyword(String keyword) {
        this.keyword = keyword;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
}

发现another answer,建议将对象从JSONObject序列化为JSONElement并返回该对象。 catch()现在有:

    catch (ValidationException ve) {            

        JSONObject jsonObject = ve.toJSON();
        Gson gson = new Gson();
        JsonElement element = gson.fromJson(jsonObject.toString(), JsonElement.class);

        return element;

    }
