使用spring-data-elasticsearch，如何更新字段映射？
提问于 2017-07-12 06:54:50
我正在使用spring-data-elasticsearch 2.1.4.RELEASE，如何使用ElasticsearchOperations更新类型的字段映射？
当我再次尝试operations.putMapping(EsJob.class)；时，出现了异常:因为字段createdBy已经存在，但我想要更新它。有人有更好的解决方案吗？

一般来说，您不能更新现有索引上的映射。这就是为什么ElasticsearchOperations-Interface不提供此功能的原因。
您可以为新索引应用新映射或在现有映射中添加新字段，也可以通过删除索引来删除映射。根据这一点，当将另一个映射放入更新现有映射时，您会收到一个错误。
如果需要进行重大更改，则必须使用此新映射重新索引数据。有关在不停机的情况下执行此操作的信息，请参阅此post。
