Example 31 with JsonNode

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

the class JsonConverterTest method testJsonSchemaMetadataTranslation.

// Schema metadata
@Test
public void testJsonSchemaMetadataTranslation() {
    JsonNode converted = parse(converter.fromConnectData(TOPIC, Schema.BOOLEAN_SCHEMA, true));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"boolean\", \"optional\": false }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertEquals(true, converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).booleanValue());
    converted = parse(converter.fromConnectData(TOPIC, Schema.OPTIONAL_BOOLEAN_SCHEMA, null));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"boolean\", \"optional\": true }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertTrue(converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).isNull());
    converted = parse(converter.fromConnectData(TOPIC, SchemaBuilder.bool().defaultValue(true).build(), true));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"boolean\", \"optional\": false, \"default\": true }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertEquals(true, converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).booleanValue());
    converted = parse(converter.fromConnectData(TOPIC, SchemaBuilder.bool().required().name("bool").version(3).doc("the documentation").parameter("foo", "bar").build(), true));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"boolean\", \"optional\": false, \"name\": \"bool\", \"version\": 3, \"doc\": \"the documentation\", \"parameters\": { \"foo\": \"bar\" }}"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertEquals(true, converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).booleanValue());
}

Example 32 with JsonNode

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

the class JsonConverterTest method nullSchemaAndArrayToJson.

@Test
public void nullSchemaAndArrayToJson() {
    // 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.
    JsonNode converted = parse(converter.fromConnectData(TOPIC, null, Arrays.asList(1, "string", true)));
    validateEnvelopeNullSchema(converted);
    assertTrue(converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME).isNull());
    assertEquals(JsonNodeFactory.instance.arrayNode().add(1).add("string").add(true), converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME));
}

Example 33 with JsonNode

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

the class JsonConverterTest method structToJson.

@Test
public void structToJson() {
    Schema schema = SchemaBuilder.struct().field("field1", Schema.BOOLEAN_SCHEMA).field("field2", Schema.STRING_SCHEMA).field("field3", Schema.STRING_SCHEMA).field("field4", Schema.BOOLEAN_SCHEMA).build();
    Struct input = new Struct(schema).put("field1", true).put("field2", "string2").put("field3", "string3").put("field4", false);
    JsonNode converted = parse(converter.fromConnectData(TOPIC, schema, input));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"struct\", \"optional\": false, \"fields\": [{ \"field\": \"field1\", \"type\": \"boolean\", \"optional\": false }, { \"field\": \"field2\", \"type\": \"string\", \"optional\": false }, { \"field\": \"field3\", \"type\": \"string\", \"optional\": false }, { \"field\": \"field4\", \"type\": \"boolean\", \"optional\": false }] }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertEquals(JsonNodeFactory.instance.objectNode().put("field1", true).put("field2", "string2").put("field3", "string3").put("field4", false), converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME));
}

Example 34 with JsonNode

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

the class JsonConverterTest method noSchemaToJson.

@Test
public void noSchemaToJson() {
    Map<String, Boolean> props = Collections.singletonMap("schemas.enable", false);
    converter.configure(props, true);
    JsonNode converted = parse(converter.fromConnectData(TOPIC, null, true));
    assertTrue(converted.isBoolean());
    assertEquals(true, converted.booleanValue());
}

Example 35 with JsonNode

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

the class JsonConverterTest method stringToJson.

@Test
public void stringToJson() {
    JsonNode converted = parse(converter.fromConnectData(TOPIC, Schema.STRING_SCHEMA, "test-string"));
    validateEnvelope(converted);
    assertEquals(parse("{ \"type\": \"string\", \"optional\": false }"), converted.get(JsonSchema.ENVELOPE_SCHEMA_FIELD_NAME));
    assertEquals("test-string", converted.get(JsonSchema.ENVELOPE_PAYLOAD_FIELD_NAME).textValue());
