在action_hibernate的validation不起作用，请教高手

RegisterAction代码：package com.mr.jsjwl.action;import java.util.Map;import com.mr.jsjwl.dao.UserDao;
import com.mr.jsjwl.dao.UserDaoImpl;
import com.mr.jsjwl.model.User;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;public class RegisterAction extends ActionSupport{
private UserDao userDao = new UserDaoImpl();
private User user = new User();  //注册提交的用户对象
private String repwd; //重复密码
private String inputCertCode; //验证码
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public String getRepwd() {
return repwd;
}
public void setRepwd(String repwd) {
this.repwd = repwd;
}
public String getInputCertCode() {
return inputCertCode;
}
public void setInputCertCode(String inputCertCode) {
this.inputCertCode = inputCertCode;
}

@Override
public String execute() throws Exception{

userDao.add(user);//保存注册的对象
return SUCCESS;

}

@Override
public void validate(){
//验证码验证
if(null == inputCertCode || "".equals(inputCertCode)){
this.addFieldError("inputCertCode", "验证码不能为空!");
}else{
Map session = ActionContext.getContext().getSession();
String certCode = session.get("certCode").toString();
if( ! certCode.equals(this.inputCertCode)){
this.addFieldError("inputCertCode", "验证码不正确!");
}
}
}
}
