無法連接到 WSO2 上的 mysql 數據庫

Question

我是 WSO2 的新手，正在嘗試連接 windows 機器上的 MySQL 數據庫。 我已經按照文件進行操作，但仍然沒有運氣。 更改 deployment.toml 文件如下

[database.apim_db]
type = mysql
url = jdbc:mysql://localhost:3306/wso2_gateway_api?autoReconnect=true
username = hide
password = hide
driver=com.mysql.cj.jdbc.Driver

[database.shared_db]
type = mysql
url = jdbc:mysql://localhost:3306/wso2_gateway?autoReconnect=true"
username = hide
password = hide
driver=com.mysql.cj.jdbc.Driver

我也在上面創建的數據庫上運行了腳本。 下面是錯誤

Answer 1

問題通過以下解決 url url = "jdbc:mysql://localhost:3306/wso2_gateway?autoReconnect=true&useSSL=false" 並添加驅動程序如下 driver="com.mysql.cj.883118182796
