我有个问题eclipse+hibernate+spring+struts

public void regInto(String r_user,String r_pwd,String r_name,String r_sex,String r_year,String r_month,String r_day,String r_email){
Login login=new Login();
login.setLoginuser(r_user);
login.setLoginpwd(r_pwd);
login.setLoginname(r_name);
login.setLoginsex(r_sex);
login.setLoginbirthday(to_date(r_year+r_month+r_day,'yyyy-mm-dd'));
System.out.println(r_year+r_month+r_day);
login.setLoginemail(r_email);
this.getHibernateTemplate().save(login);
}
