我已经设置了一个使用Tomcat的开发环境。为了启用多个数据环境，我已经使用JNDI来引用项目中的数据源。
但是，当我尝试在IntelliJ开发期间使用JPA控制台时，它出错：

这一关键功能是 JNDI service is disabled 。这很有意义，因为JNDI连接存储在Tomcat服务器上（server.xml和context.xml）。
我是否有办法在不将凭据存储到presistence.xml？
我现在唯一能让它工作的方法是在评论和未注释的代码之间切换我的persistence.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
