从JPA Native Query获取列名

我的Web应用程序中有一个管理控制台，允许管理员在我们的数据库上执行自定义SQL SELECT查询。

I have an administrative console in my web application that allows an admin to perform a custom SQL SELECT query on our database.

在下面，应用程序正在使用Hibernate，但这些查询不是HQL，它们是纯SQL，所以我使用这样的Native Query：

Underneath, the application is using Hibernate, but these queries are not HQL, they're pure SQL, so I'm using a Native Query like this:

protected EntityManager em;

public List<Object[]> execute(String query) {
    Query q = em.createNativeQuery(query);
    List<Object[]> result = q.getResultList();
    return result;
}

这是正常的，但它只返回数据行，没有额外的信息。我想要的是获取列名，所以当我将结果打印回给用户时，我也可以打印一个标题来显示各列的内容。

This works correctly, but it only returns the rows of data, with no extra information. What I would like is to also get the column names, so when I print the results back to the user I can also print a header to show what the various columns are.

有没有办法做到这一点？

Is there any way to do this?
