應用程序無法連接到MySql數據庫 - 訪問被拒絕

我將我的應用程序切換到JPA，並非常喜歡標準化API的想法。應用程序無法連接到MySql數據庫 - 訪問被拒絕

之前，我使用的是Spring JDBC模板，並且使Tomcat設置了我的數據庫連接池，它工作正常。

我現在使用Hibernate3/JPA 2.0/Spring 3.0來設置我的ORM。

但是，現在當我嘗試運行一個簡單的測試，我得到以下幾點：

我可以證實它的工作日食相同的實例中，通過使用數據源資源管理器。我可以使用相同的密碼和用戶名連接到相同的數據庫沒有問題。我將SSH隧道連接到服務器，並將其換爲localhost：並且沒有運氣。

我甚至嘗試轉換到Apache公用程序dbcp不幸運。

這是我的應用程序配置文件春天：

根據堆棧跟蹤：

Caused by: java.sql.SQLException: Access denied for user 'user'@'mymachinename'

請檢查您提供的DB用戶名和密碼，並確保訪問您的SQL Server上授予。

它最終成爲一個案件不匹配。重新評估和雙重檢查案例向我顯示了錯誤。謝謝！ – ClutchDude 2011-03-24 16:13:36
