Index [CruisingCompany] not found.； nested exception is [CruisingCompany]

 Index [CruisingCompany] not found.; nested exception is [CruisingCompany] ElasticsearchStatusException[Elasticsearch exception [type=invalid_index_name_exception, reason=Invalid index name [CruisingCompany], must be lowercase]]

org.springframework.data.elasticsearch.NoSuchIndexException: Index [CruisingCompany] not found.; nested exception is [CruisingCompany] ElasticsearchStatusException[Elasticsearch exception [type=invalid_index_name_exception, reason=Invalid index name [CruisingCompany], must be lowercase]]

 使用es从数据库向es导入数据时,报错提醒我索引名必须小写,我寻思着已经小写了为啥还报错

 结果发现原因是实体类没有指定索引名

 问题解决
