如何从jpa / hibernate类快速生成persistence.xml

Question

It is sometimes tedious to add class names manually to the persistence.xml file for hibernate configuration. Is there a way to quickly generate the <class>com.something.Entity1</class> part of the file?

Answer 1

Found a simple way, using the code from dzone. And just print them out and copy from the console. Here it is for anyone interested.

Class[] classex = getClasses(Entity1.class.getPackage().getName());
    for (Class c : classex) {
        if (c.getName().contains("$")) continue;
        if (!c.isAnnotationPresent(javax.persistence.Entity.class)) continue;
        System.out.println("<class>" + c.getName() + "</class>");
    }
