bug:1、the last packet sent successfully to the server was 0 milliseconds ago 2、avoid mutating a prop
1、the last packet sent successfully to the server was 0 milliseconds ago
錯誤提示
the last packet sent successfully to the server was 0 milliseconds ago
問題簡述
在啟動spring-boot專案時,會提示這個錯誤,這個問題十有八九是資料庫連線的問題,因為資料庫連結錯誤等導致專案啟動時連結不上資料庫
問題解決
果不其然,問題出在了配置檔案,使用的資料庫的url錯誤,修改後就好了。
2、avoid mutating a prop
錯誤提示
問題簡述
在使用vue作為前端框架,對接介面時,子元件直接修改了父元件傳過來的props,這導致了上述錯誤的出現。
問題解決
正常情況下,如果需要子元件修改父元件的相關的值,可以通過this.$emit("update:xxx",xxx)
來實現。
示例:
父元件:
<Child :test.sync="fatherTest"></Child>
子元件:
this.$emit("update:test",nowVal)
