在JHipster中創建Spring Bean時為什么會出錯？

[英]Why am I getting an error when creating Spring Beans in JHipster?

 原文  2014-10-06 20:01:37  7   2    java/ mysql/ node.js/ spring/ jhipster

問題描述

我剛剛使用yo jhipster在新計算機上從頭開始創建了一個項目，在運行npm install，bower install等之后，它交付了許多例外。 似乎它無法訪問mysql數據庫，但我尚未對其進行任何更改，因此沒有理由它不應該工作，因為它應該是開箱即用的。 有人知道這個問題的解決方案嗎？

錯誤：

作為例外說明：

Caused by: java.net.ConnectException: Connection refused: connect

這是因為未打開MySQL連接。 也許它沒有運行。 也許YAML文件中的參數不正確：您是否有“ CastIT”數據庫？ 用戶可以在沒有密碼的情況下以“ root”用戶訪問嗎？ 您可以嘗試與MySQL工作台連接。

如果使用的是MysqlDataSource，則可能會忽略您指定的url參數。 該url通常用於基於驅動程序的（驅動程序類）配置。 嘗試設置serverName和databaseName 。
