这篇博客介绍了如何使用Java客户端检查Elasticsearch索引是否存在，若不存在则动态创建，并按月份生成索引。同时，文章还涉及到设置索引别名的操作，为数据插入提供指南。

第一步：判断索引是否存在：

//判断索引是否已经存在String indexName = Constans.ES_INDEX_TIME+"_"+DateUtils.getDateStrSub(new Date());Client client = elasticsearchTemplate.getClient();//返回值是布尔类型，判断方法是client对象下indices()方法的exists方法，在这个方法里有索引的名字；boolean exists = client        .admin()        .indices()        .exists(new IndicesExistsRequest()        .indices(new String[]{indexName}))        .actionGet().isExists();

第二步：如果不存在则创建索引：

if(!exists){    initEsIndex(indexName,client);}

第三步：插入数据：

IndexRequest indexRequest = new IndexRequest()        .index(indexName)        .type(Constans.ES_TYPE_TIME)        .versionType(VersionType.EXTERNAL)        .version(1)        .id(rabbitMessage.getMessageId())        .source(source);client.index(indexRequest);
