重新部署后，Netbeans将数据库表类型从InnoDB更改为MyISAM。
[英]Netbeans changes DB table type from InnoDB to MyISAM after redeployment.
问题描述
I set up the database tables to use the InnoDB engine and run my project from netbeans, everything runs fine until i make a change in a file and save it, after redeploying the project again my database tables change from InnoDB to MyISAM and all entries from database tables get deleted. 
我设置数据库表以使用InnoDB引擎并从netbeans运行我的项目，一切运行良好，直到我对文件进行更改并保存为止，再次重新部署项目后，我的数据库表从InnoDB更改为MyISAM，所有条目都从数据库表被删除。 If someone can help it would be greatly appreciated. 如果有人可以帮助，将不胜感激。 I am running glassfish server 4. 我正在运行glassfish服务器4。

I solved the problem. 我解决了问题。 Edited the persistence.xml file from configuration files folder and changed the property value: property name="eclipselink.ddl-generation" value="drop and create tables" to property name="eclipselink.ddl-generation" value="none" 从配置文件文件夹中编辑了persistence.xml文件，并将属性值更改为：property name =“ eclipselink.ddl-generation” value =“拖放并创建表”变为property name =“ eclipselink.ddl-generation” value =“ none”
