今天es在保存數據的時候報錯
org.frameworkset.elasticsearch.ElasticSearchException: {"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}
1.解決辦法：curl -XPUT -H "Content-Type: application/json" http://127.0.0.1:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'，直接在es所在機器執行該命令即可。
2.執行后，再保存數據時會間歇性報錯，再次查找原因，是磁盤滿了，清理磁盤即可（參考Blog：https://www.cnblogs.com/Bruce_H21/p/9088509.html）
