JPA EntityManager和JavaFx [英] JPA EntityManager and JavaFx

问题描述

我尝试在NetBeans中的JavaFx应用程序中使用EntityManager（我的解决方案连接到postgres），我按如下方式进行：

I tried to use EntityManager in a JavaFx application in NetBeans (my solution is connected to postgres), I proceeded as follows :

1）我创建了一个持久性单元。
2）然后从数据库中添加了实体类。

1) I created a Persistence Unit. 2) Then Added the Entity Classes from Database.

但我无法让它工作，我试图在另一个线程中寻求帮助< a href =https://stackoverflow.com/questions/16496448/cant-persist-using-entity-manager-in-javafx#log-in>实体经理无法在JavaFX中工作但无法获得它也工作，是否有任何干净，清晰的教程或课程，我可以清楚地找到如何在JavaFx Fxml应用程序中使用EntityManager

but I can't get it to work, I tried to ask for some help in another thread Entity Manager not working in JavaFX but can't get it work either, is there any clean and clear tutorial or lesson where I can find clearly how to use a EntityManager in a JavaFx Fxml Application

推荐答案
