Question

我正在尝试使用休眠将本地数据库连接到我的应用程序。我收到以下错误：

Jul 02, 2019 9:20:08 PM org.hibernate.Version logVersion

任何有关如何解决此问题的帮助将不胜感激。

最初，我遇到了“java.lang.NoClassDefFoundError: java/sql/SQLException”异常，因此在将其视为 Stack Overflow 其他地方的建议解决方案后我添加了“requires java.sql”，但现在出现了上述异常。我不确定我的代码哪里出了问题或缺少什么。

这是我的 module-info.java 文件：

module ProjectDBTest {

    requires java.persistence;

    //requires lombok;

    requires javafx.graphics;

    requires org.hibernate.orm.core;

    requires java.naming;

    requires java.sql;

    exports ProjectDBTest2.DB;

}

我终于设法通过更新我的 module-info.java 文件来解决这个问题，包括：module AlienDB {&nbsp; &nbsp; requires static lombok;&nbsp; &nbsp; requires java.persistence;&nbsp; &nbsp; requires org.hibernate.orm.core;&nbsp; &nbsp; requires java.naming;&nbsp; &nbsp; requires java.sql;&nbsp; &nbsp; requires com.sun.xml.bind;&nbsp;&nbsp; &nbsp; requires net.bytebuddy;&nbsp; &nbsp; opens Aliens to org.hibernate.orm.core;&nbsp; &nbsp; exports Aliens;}之前我添加了 java.xml.bind，这导致了更多问题。
