@test
public void updateDoc() throws Exception {
//tag::single-doc-update
Product product = new Product("bk-1", "City bike", 666);

    esClient.update(u -> u
                    .index("products")
                    .id("bk-1")
                    .upsert(product),
            Product.class
    );
    //end::single-doc-update
}

报错：

我执行下列代码都是成功的：
@test
public void singleDocumentDSL() throws Exception {

    //tag::single-doc-dsl
    Product product = new Product("bk-1", "City bike", 123.0);

    IndexResponse response = esClient.index(i -> i
            .index("products")
            .id(product.getSku())
            .document(product)
    );

    log.info("Indexed with version " + response.version()); //每当对文档执行更新操作时，版本号会增加，以便跟踪文档的变化历史。
    //end::single-doc-dsl
}

 @Test
public void deleteDocument() throws Exception {
    esClient.delete(d -> d.index("products").id("bk-1"));
}
