Answer 1

自己搞定了。。Hql 少写了   /**
 * 登录
 */
public int getUserLogin(String userName, String password) {
// TODO Auto-generated method stub
String hql = "select count(u) from Users u where u.userName=? and password=?";
List para = new ArrayList();
para.add(userName);
para.add(password);
return super.searchCount(hql, para);
}

Answer 2

java.lang.NumberFormatException: For input string: "net.entity.Users@23b5c3"
最浅显的看的话楼主应该不会看不出来。
恭喜下楼主了，自己解决了。
