Examples with JsonNode com.fasterxml.jackson.databind.JsonNode used on opensource projects

Example 36 with JsonNode

use of com.fasterxml.jackson.databind.JsonNode in project kafka by apache.

the class JsonConverterTest method mapToJsonNonStringKeys.

@Test
public void mapToJsonNonStringKeys() {
    Schema intIntMap = SchemaBuilder.map(Schema.INT32_SCHEMA, Schema.INT32_SCHEMA).build();
    Map<Integer, Integer> input = new HashMap<>();
    input.put(1, 12);
    input.put(2, 15);
    JsonNode converted = parse(converter.fromConnectData(TOPIC, intIntMap, input));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"map\", \"keys\": { \"type\" : \"int32\", \"optional\": false }, \"values\": { \"type\" : \"int32\", \"optional\": false }, \"optional\": false }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertTrue(converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).isArray());
    ArrayNode payload = (ArrayNode) converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME);
    assertEquals(2, payload.size());
    Set<JsonNode> payloadEntries = new HashSet<>();
    for (JsonNode elem : payload) payloadEntries.add(elem);
    assertEquals(new HashSet<>(Arrays.asList(JsonNodeFactory.instance.arrayNode().add(1).add(12), JsonNodeFactory.instance.arrayNode().add(2).add(15))), payloadEntries);
}

Example 37 with JsonNode

use of com.fasterxml.jackson.databind.JsonNode in project kafka by apache.

the class JsonConverterTest method nullSchemaAndMapToJson.

@Test
public void nullSchemaAndMapToJson() {
    // This still needs to do conversion of data, null schema means "anything goes". Make sure we mix and match
    // types to verify conversion still works.
    Map<String, Object> input = new HashMap<>();
    input.put("key1", 12);
    input.put("key2", "string");
    input.put("key3", true);
    JsonNode converted = parse(converter.fromConnectData(TOPIC, null, input));
    validateEnvelopeNullSchema(converted);
    assertTrue(converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME).isNull());
    assertEquals(JsonNodeFactory.instance.objectNode().put("key1", 12).put("key2", "string").put("key3", true), converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME));
}

Example 38 with JsonNode

use of com.fasterxml.jackson.databind.JsonNode in project kafka by apache.

the class JsonConverterTest method floatToJson.

@Test
public void floatToJson() {
    JsonNode converted = parse(converter.fromConnectData(TOPIC, Schema.FLOAT32_SCHEMA, 12.34f));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"float\", \"optional\": false }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertEquals(12.34f, converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).floatValue(), 0.001);
}

Example 39 with JsonNode

use of com.fasterxml.jackson.databind.JsonNode in project kafka by apache.

the class JsonConverterTest method byteToJson.

@Test
public void byteToJson() {
    JsonNode converted = parse(converter.fromConnectData(TOPIC, Schema.INT8_SCHEMA, (byte) 12));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"int8\", \"optional\": false }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertEquals(12, converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).intValue());
}

Example 40 with JsonNode

use of com.fasterxml.jackson.databind.JsonNode in project kafka by apache.

the class JsonConverterTest method longToJson.

@Test
public void longToJson() {
    JsonNode converted = parse(converter.fromConnectData(TOPIC, Schema.INT64_SCHEMA, 4398046511104L));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"int64\", \"optional\": false }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertEquals(4398046511104L, converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).longValue());
