SQLException-找不到適用於jdbc：postgresql的驅動程序

[英]SQLException - No suitable driver found for jdbc:postgresql

問題描述

我有個問題。 我使用Persistence.xml的憑據創建了EntityManager，但出現錯誤消息“找不到適用於jdbc：postgresql / localhost：9999 / DB的驅動程序”。

我不明白我在做什么錯，請您幫我一下或給我一些有關如何解決此問題的建議。 提前致謝。

我使用的配置是：

Persistence.xml： 

    <persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
