1. UserAction类，从DispatchAction 继承过来
package com.yanek.demo.ssh.action;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;
import com.yanek.demo.ssh.bean.UserForm;
import com.yanek.demo.ssh.service.UserService;
import com.yanek.demo.ssh.vo.User;
public class UserAction extends DispatchAction {
private UserService userService;
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
/*
* @Override
*
*
* public ActionForward execute(ActionMapping mapping, ActionForm form,

public ActionForward save(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
System.out.println("execuet save");
UserForm uf = (UserForm) form;
String username = uf.getUsername();

HttpServletRequest request, HttpServletResponse response)
throws Exception {

}
2. UserForm actionForm类

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;
public class UserForm extends ActionForm {
@Override
public void reset(ActionMapping arg0, HttpServletRequest arg1) {
this.username = null;
this.password = null;
this.id = 0;
this.email = null;
}
@Override
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (username == null || username.equals("")) {
errors.add("username", new ActionMessage(
"hello.error.username.null"));
}
if (password == null || password.equals("")) {
errors.add("password", new ActionMessage(
"hello.error.password.null"));
}
if (email == null || email.equals("")) {
errors.add("email", new ActionMessage("hello.error.email.null"));
}
return errors;
}
private int id;
private String username;
private String password;
private String email;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
