使用hibernate查询部分字段的方法

数据库操作：
List<UserAudit> userList = null;
		try {
			String hql="select new UserAudit(startip,endip,begintime,endtime) from UserAudit where uname=?";
			userList=(List<UserAudit>)super.createQuery(hql, userName).list();
		} catch (HibernateException e) {
			logger.error(e); 
		}
实体类：
public class UserAudit implements Serializable{
	private Integer uid;
	private String uname;
	private String upasswd;
	private Integer utype;
	private Integer umode;
	private String uemail;
	private String uphone;
	private String udescription;
	private Date udate;
	private String upermission;
	private String uclientip;
	private Integer udel;
	private String startip;
	private String endip;
	private String begintime;
	private String endtime;
	public UserAudit() {
		super();
	}
	public UserAudit(String startip, String endip, String begintime,
			String endtime) {
		super();
		this.startip = startip;
		this.endip = endip;
		this.begintime = begintime;
		this.endtime = endtime;
	}
