Question

我是休眠新手。实际上，我只是尝试连接到我的数据库（postgres）。应用程序崩溃：https://github.com/sielus/JavaFX_socket_mini_chat/blob/dev/src/main/java/org/sql_manager/testSystem.java

EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("JavaFX_socket_mini_chat");

错误：

这是我的 pom 文件：https://github.com/sielus/JavaFX_socket_mini_chat/blob/dev/pom.xml

和我的持久性文件：https://github.com/sielus/JavaFX_socket_mini_chat/blob/dev/src/main/resources/META-INF/persistence.xml

我猜这是最基本的问题，但是就像我说的那样，我对休眠完全陌生。如有任何帮助，谢谢
