Jhipster和Postgres連接

Question

我試圖運行基於本教程由創作者自己在Jhipster項目：https://www.youtube.com/watch?v=d1MEM8PdAzQ但它不能連接到Postgres的

請參見下面的錯誤：

我如何將Jhipster與postgreSQL連接？我在jhipster新手

Answer 1

JHipster創建3個配置文件： -

1. application.yml - Spring主啓動配置文件。
2. application-dev.yml
3. application-prod.yml

的application.yml文件中包含的公共屬性，另2保存特定屬性以開發和生產環境。

如果你看看application-dev.yml你會看到類似以下內容： -

datasource: 
     type: com.zaxxer.hikari.HikariDataSource 
     url: jdbc:postgresql://localhost:5432/myapp 
     username: myapp 
     password: 

不過，你仍然必須創建PostgreSQL數據庫 - 最簡單的方法是通過pgAdmin的工具，但你也可以創建它通過命令行工具 - 快速谷歌將幫助你！
