java - 在 Hibernate 返回的列表上调用 List#toArray() 时出现 ArrayStoreException

Question

我正在尝试将 Hibernate 返回的 List 转换为 UserDetails[] 数组，如下所示:

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
List<UserDetails[]> oo = session.createSQLQuery("SELECT * FROM `userdetails` WHERE 1 ").list();
System.out.println(oo.size()); // Until here it works fine and it shows me the rows I asked in my query.
UserDetails[]us = oo.toArray(new UserDetails[oo.size()]); // Here it throws java.lang.ArrayStoreException
session.close();

但是，它会抛出一个 java.lang.ArrayStoreException。这是怎么引起的，我该如何解决？

Answer 1

可以直接打印列表:

for(UserDetails list: oo){
    System.out.println("Result"+ list.toString());
}

或者获取具体数据

for(UserDetails list: oo){
    System.out.println("Result"+ list.getId());
}
