From source file:org.springframework.cloud.schema.avro.AvroMessageConverterSerializationTests.java

@Test
public void sourceWriteSameVersion() throws Exception {
    User specificRecord = new User();
    specificRecord.setName("joe");

            .getResourceAsStream("schemas/user.avsc"));
    GenericRecord genericRecord = new GenericData.Record(v1);
    genericRecord.put("name", "joe");
    SchemaRegistryClient client = new DefaultSchemaRegistryClient();
    AvroSchemaRegistryClientMessageConverter converter = new AvroSchemaRegistryClientMessageConverter(client);
    converter.setDynamicSchemaGenerationEnabled(false);
    converter.setContentTypeResolver(new StringConvertingContentTypeResolver());
    converter.setCacheManager(new ConcurrentMapCacheManager());
    converter.afterPropertiesSet();//w  w  w . ja va2s  .co m

    Message specificMessage = converter.toMessage(specificRecord,
            new MutableMessageHeaders(Collections.<String, Object>emptyMap()),
            MimeTypeUtils.parseMimeType("application/*+avro"));
    SchemaReference specificRef = extractSchemaReference(
            MimeTypeUtils.parseMimeType(specificMessage.getHeaders().get("contentType").toString()));

    Message genericMessage = converter.toMessage(genericRecord,
            new MutableMessageHeaders(Collections.<String, Object>emptyMap()),
            MimeTypeUtils.parseMimeType("application/*+avro"));
    SchemaReference genericRef = extractSchemaReference(
            MimeTypeUtils.parseMimeType(genericMessage.getHeaders().get("contentType").toString()));

    Assert.assertEquals(genericRef, specificRef);
    Assert.assertEquals(1, genericRef.getVersion());
