java - IDEA中怎么自动生成Hibernate对应的*.hbm.xml文件？

public class Users {
    private int uid;
    private String username;
    private String password;

    public Users() {

    }

    public Users(int uid, String username, String password) {
        this.uid = uid;
        this.username = username;
        this.password = password;
    }
    /* getter与setter方法 */

请问在IDEA中应该怎么生成Users.hbm.xml文件呢？
