java - 通过 Elasticsearch Java API 批量更新抛出异常

Question

Elasticsearch Java Api 中的批量更新抛出以下异常。

下面是我写的代码。

    BulkRequestBuilder bulkRequestBuilder = client.prepareBulk();

    for (String documentId : documentIds)
    {
        bulkRequestBuilder.add(client.prepareUpdate("39302", "3", documentId).setScript("ctx._source.customerName=\"Ramaraj\";"));
    }

    BulkResponse bulkResponse = bulkRequestBuilder.execute().actionGet();

这与我为批量索引编写的方式相同。它工作正常。

提前致谢。

注意:几天前才添加了 java api 中的批量更新。

正如异常所说，没有请求被添加到 BulkRequest 对象。如果您在 for 循环中添加的记录实际上被添加到构建器对象中，则进行调试。最近发现这篇文章有同样的问题:ActionRequestValidationException
