购物网站开发设计动漫设计与制作好就业吗

一，谷粒商城实战笔记-133-城业务-商品上架-远程上架接口

1，开发目标

这一节的主要内容是完成Search模块的保存商品信息到Es。

2，详细设计

2.1，提前建立索引

虽然ES具有自动建立索引和类型推断的能力，但在实际的开发过程中，最佳实践是关闭ES的这个能力。根据设计好的mapping结构，提前在es中建立索引。

2.2，构造批量操作请求参数

		BulkRequest bulkRequest = new BulkRequest();for (SkuEsModel skuEsModel : skuEsModels) {//构造保存请求IndexRequest indexRequest = new IndexRequest(EsConstant.PRODUCT_INDEX);indexRequest.id(skuEsModel.getSkuId().toString());String jsonString = JSON.toJSONString(skuEsModel);indexRequest.source(jsonString, XContentType.JSON);bulkRequest.add(indexRequest);}

2.3，使用HighLevelClient调用bulk请求保存数据

调用bulk接口，保存数据，并根据响应进行异常处理。

BulkResponse bulk = esRestClient.bulk(bulkRequest, GulimallElasticSearchConfig.COMMON_OPTIONS);//TODO 如果批量错误boolean hasFailures = bulk.hasFailures();List<String> collect = Arrays.asList(bulk.getItems()).stream().map(item -> item.getId()).collect(Collectors.toList());log.info("商品上架完成：{}",collect);return hasFailures;

我把下面这段代码注释了反而不报错了。

Options中配置的baseLimit远大于0啊，为什么会报错呢？
