Load external data inside custom validator during validation #1047
-
|
Hi there, I took a look into the Docs and existing discussions, but didn't find an answer to my question. So I hope someone can help me with that: Currently my implementation looks similar to this code: JsonMetaSchema customMetaSchema = JsonMetaSchema.builder(JsonMetaSchema.getV202012())
.keyword(new CustomKeyword())
.build()
JsonSchemaFactory jsonSchemaFactory = new JsonSchemaFactory.Builder().defaultMetaSchemaIri(customMetaSchema.getIri())
.metaSchema(customMetaSchema)
.build();
JsonSchema jsonSchema = jsonSchemaFactory.getSchema(jsonNode);
ValidationResult validationResult = jsonSchema.validateAndCollect(node);And the Collector would be something like this: public class CustomCollector implements Collector<List<String>> {
private final ExternalService externalService;
public CustomCollector(ExternalService externalService) {
this.externalService = externalService;
}
@Override
public void combine(Object object) {
}
@Override
public List<String> collect() {
return externalService.loadExternalData();
}
}If the collector is the right choice to do this, what is the way of including them into the validation and use the collected data inside a custom validator? TIA |

Not clear what your use case is. What are you going to do with this data? If you want to load data in a validator you would just have a service in your custom validator implementation to load the data. Nothing to do with a collector. |

You're right, sorry. It's not getting that clear. Yes I can have the service in the validator, but the "problem" is the following: Is there a smart way of getting this into the validation execution when creating the schema and validate against it? |

You can pass data on a per execution basis through the Set<ValidationMessage> messages = schema.validate(inputData, InputFormat.JSON, executionContext -> {
executionContext.getCollectorContext().getCollectorMap().put("userData", "myUserData");
});The |

Alright perfect. That seems to work as intended 👍 |

You can pass data on a per execution basis through the
ExecutionContext.The
validatemethod in the validator has aexecutionContextparameter which you can use to get the data.
