    public static final String DATA_INDEX_TYPE = "user";
}

@RunWith(SpringRunner.class)
@SpringBootTest
public class SingleDocTests {
    @Autowired
    private TransportClient transportClient;

    @Test
    public void addTest() throws Exception {
        String id = "10000";
        XContentBuilder xContentBuilder = XContentFactory.jsonBuilder().startObject()
                .field("name", "test001")
                .field("age", 501)
                .field("address", "蘇州市獨墅湖")
                .endObject();
        IndexResponse indexResponse = transportClient.prepareIndex(ESConstant.DATA_INDEX_NAME,
                ESConstant.DATA_INDEX_TYPE, id).setSource(xContentBuilder).execute().get();
        // 文件不存在(CREATED) 存在更新(OK)
        System.out.println(indexResponse.status());
