SpringBoot-2.X 學習筆記06 整合elasticsearch-7.3.0 實現簡單增刪改查

springboot-2. 整合elasticsearch-7.3.0實現簡單 增刪改查 (修改沒有實現)*
首先 elasticsearch 配置文件 elasticsearch.yml 中的 cluster.name:xxx 要和 SpringBoot 中的spring.data.elasticsearch.cluster-name=xxx 名字一樣。

cluster.name: my-application
spring.data.elasticsearch.cluster-name=my-application

增加 http://127.0.0.1:8080/es/save?id=2

查詢 http://127.0.0.1:8080/es/getbyid?id=2

查詢所有 http://127.0.0.1:8080/es/getall

刪除 http://127.0.0.1:8080/es/deletebyid?id=2 結果與 查詢所有 比較
