與連接MySQL的

Question

我下面在這裏http://thecafetechno.com/tutorials/spring/spring-ormlite-example-integration-eclipse/的ORMLite JDBC例子來學習如何使用ORMLite連接到MySQL在Java中，但是當我運行的IntelliJ程序ORMLite JDBC錯誤，我得到了以下錯誤：

com.intellij.rt.execution.application.AppMain main.CellPhoneDemo 
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". 
SLF4J: Defaulting to no-operation (NOP) logger implementation

我相信MySQL服務器正在我的Mac上運行，因爲我使用單獨的工具「phpmyadmin」來訪問數據庫。我使用從Maven導入的Java（版本5.1.29）的MySQL連接器。所以我很困惑什麼可能會出錯？謝謝

我犯了一個愚蠢的錯誤。

String databaseUrl = "jdbc:mysql:/localhost:3306/my_db應該是String databaseUrl = "jdbc:mysql://localhost:3306/my_db。
