spring boot 2.2.6 elastic search 7.6.2 oss的批量索引不工作

Question

我不能用spring boot做批量索引。根据我的理解，我不需要创建索引来进行批量索引。

请找到我用于批量索引的代码

 BulkRequest blk = new BulkRequest();
 blk.add(new IndexRequest(index).id(id).source(stringdata, XContentType.JSON));
 return restClient.bulk(blk,RequestOptions.DEFAULT);

注意:我可以用弹簧弹性数据的方式来做插入

这里是批量请求的json输入，

{
    "test":"test"
}

下面是我观察到的错误

下面是resthighlevelclient客户端配置

@Configuration
public class RestClientConfig extends AbstractElasticsearchConfiguration {

    @Override
    @Bean(destroyMethod = "close")
    public RestHighLevelClient elasticsearchClient() {

        final ClientConfiguration clientConfiguration = ClientConfiguration.builder().
                connectedTo("localhost:9200") 
                //.usingSsl(sslContext).
                .build();

        return RestClients.create(clientConfiguration).rest();
    }

    /*
     * @Bean
     * 
     * @Override public EntityMapper entityMapper() {
     * 
     * ElasticsearchEntityMapper entityMapper = new
     * ElasticsearchEntityMapper(elasticsearchMappingContext(), new
     * DefaultConversionService());
     * entityMapper.setConversions(elasticsearchCustomConversions());
     * 
     * return entityMapper; }
     */

    @Bean
    ElasticsearchRestTemplate elasticsearchTemplate() {
        return new ElasticsearchRestTemplate(elasticsearchClient());
    }

}

Answer 1

如异常所示，您缺少索引的type。创建IndexRequest时，必须声明索引类型：

new IndexRequest(index).id(id).type("_doc").source(stringdata, XContentType.JSON);

或

IndexRequest indexRequest = new IndexRequest(index, "_doc", id)
        .source(stringdata, XContentType.JSON);

建议使用_doc作为索引类型

从日志中我可以看到您使用的是6.8.7版本的Elasticserach。您可以查看适用于Java here的Bulk API7.6、适用于Java here的Bulk API6.8以及索引API here

Answer 2

Spring Boot 2.2.6使用Spring Data Elasticsearch 3.2.x，它是为Elasticsearch 6.8构建的，不能与Elasticsearch 7一起使用。

您需要Spring Data Elasticsearch 4.0才能与Elasticsearch 7配合使用。
