问无法使用设置和源Java创建索引

EN

使用Java设置Source和Settings的唯一方法是使用这样的代码(这是一个简单的测试类，只有一个@test方法)：

   @RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest

@TestPropertySource(value = "classpath:testApplication.properties")
public class ESJavaAPITests {


    @Value("${ES.cluster.name}")
    private String    CLUSTER_NAME;

    @Value("${ES.host}")
    private String    HOSTNAME;

    @Value("${ES.port}")
    private Integer   HOST_PORT;

    private static final String BOOK_INDEX_NAME ="bookshop";
    private static final String BOOK_TYPE_NAME ="book";

    private Client client(){
        Settings settings = Settings.settingsBuilder()
                .put("cluster.name", CLUSTER_NAME)
                .build();

        return new TransportClient.Builder().settings(settings).build()
                .addTransportAddress(
                        new InetSocketTransportAddress(
                                new InetSocketAddress(HOSTNAME, HOST_PORT))
                );

    }

    @Test
    public void shouldSaveDocToPredefinedShard() throws IOException {
        //delete all indexes if any
        client().admin().indices().prepareDelete("_all").get();


        CreateIndexResponse createIndexRequestBuilder = client().admin().indices()
                .prepareCreate(BOOK_INDEX_NAME)
                .setSettings(
                        Settings.settingsBuilder()
                                .put("index.number_of_shards", 2)
                                .put("index.number_of_replicas", 2)
                )
                .execute()
                .actionGet();

        IndexResponse response1 = client().prepareIndex(BOOK_INDEX_NAME, BOOK_TYPE_NAME, "id1")
                .setSource(XContentFactory.jsonBuilder()
                        .startObject()
                            .field("title", "Clean COde")
                            .field("author", "John Smith")
                        .endObject()
                )
                .setRouting("route1")
                .get();

        IndexResponse response2 = client().prepareIndex(BOOK_INDEX_NAME, BOOK_TYPE_NAME, "id2")
                .setSource(XContentFactory.jsonBuilder()
                        .startObject()
                            .field("title", "Learn Scala")
                            .field("author", "John Doe")
                        .endObject()
                )
                .setRouting("route2")
                .get();
    }
}

当我第一次运行它时，这是可行的。但当我第二次运行它的时候

为什么当我第二次运行它时，这似乎是一个问题?

如何使用以下方法创建索引和添加两个示例性文档：

1. 碎片nr
2. 复制nr
3. 索引名
4. 索引类型
5. 新文件id。 用Java？
