ES 修改mapping
elasticsearch 并不支持修改mapping映射字段中的信息，如：字段类型、字段名称、分词器等。
需要先创建一个新的索引(mapping用最新的)，复制原索引中的数据，删除旧索引(删除前必须检查原索引中的数据是否全部复制到新索引中)，设置别名。具体步骤如下:
步骤1:查看原索引mapping&settings
原索引:mapping&settings

}步骤3:同步数据
POST _reindex
{

},

"index": "rosegal_new"
}
}步骤4:删除原索引(注意必须等数据同步完后才能删除)
DELETE rosegal步骤5：设置别名
POST /_aliases
{
"actions": [
{"add": {"index": "rosegal_new", "alias": "rosegal"}}
]
}
