import com.test.service.UserService;
public class SaveUserAction extends ActionSupport
{
private User user;
private UserService service;
public User getUser()
{
return user;
}
public void setUser(User user)
{
this.user = user;
}
public UserService getService()
{
return service;
}
public void setService(UserService service)
{
this.service = service;
}
@Override
public String execute() throws Exception
{
this.service.save(this.user);
return SUCCESS;
}
@Override
@SuppressWarnings("unchecked")
public void validate()
{
Map map = this.getFieldErrors();
Set set = map.keySet();
for (Iterator iter = set.iterator(); iter.hasNext();)
{
System.out.println(map.get(iter.next()));
}
}
}
編寫後面的service和dao
國際化，在src下建立資源文件：struts.properties
struts.custom.i18n.resources=globalMessages//可以用視圖形式添加，並且中文能自動轉換
src下添加中英文資源文件
globalMessages_en.properties
firstname=firstname
lastname=lastname
age=age
globalMessages_zh.properties
firstname=/u59D3
lastname=/u540D
age=/u5E74/u9F84
頁面顯示：
<s:textfield name="user.firstname" label="%{getText('firstname')}"></s:textfield>
上面的方式是取到資源文件內容
：<s:textfield name="user.firstname" label="firstname></s:textfield>//靜態文本形式
Dao的編寫：
package com.test.dao;
import java.util.List;
import com.test.bean.User;
public interface UserDAO
{
public void saveUser(User user);
public void removeUser(User user);
public User findUserById(Integer id);
public List<User> findAllUsers();
public void updateUser(User user);
}
建立實現類
package com.test.dao.impl;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.test.bean.User;
import com.test.dao.UserDAO;
public class UserDAOImpl extends HibernateDaoSupport implements UserDAO
{
@SuppressWarnings("unchecked")
public List<User> findAllUsers()
{
String hql = "from User user order by user.id desc";
return (List<User>)this.getHibernateTemplate().find(hql);
}
public User findUserById(Integer id)
{
User user = (User) this.getHibernateTemplate().get(User.class, id);
return user;
}
public void removeUser(User user)
{
this.getHibernateTemplate().delete(user);
}
public void saveUser(User user)
{
this.getHibernateTemplate().save(user);
}
public void updateUser(User user)
{
this.getHibernateTemplate().update(user);
}
}
建立服務層代碼：
package com.test.service;
import java.util.List;
import com.test.bean.User;
public interface UserService
{
public List<User> findAll();
public void save(User user);
public void delete(User user);
public User findById(Integer id);
public void update(User user);
}
服務的實現：
package com.test.service.impl;
import java.util.List;
import com.test.bean.User;
import com.test.dao.UserDAO;
import com.test.service.UserService;
public class UserServiceImpl implements UserService
{
private UserDAO userDao;
public UserDAO getUserDao()
{
return userDao;
}
public void setUserDao(UserDAO userDao)
{
this.userDao = userDao;
}
public void delete(User user)
{
this.userDao.removeUser(user);
}
public List<User> findAll()
{
return this.userDao.findAllUsers();
}
public User findById(Integer id)
{
return this.userDao.findUserById(id);
}
public void save(User user)
{
this.userDao.saveUser(user);
}
public void update(User user)
{
this.userDao.updateUser(user);
}
}
配置strut.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

配置spring文件：

<beans

加載順序：先加載struts-default.xml，struts-plugin.xml ，struts.xml
整合的時候把：asm2.2.3.jar去掉，與hibernate包衝突
過濾辦法：
把頁面和struts2默認就是utf-8和MySQL也設置成utf-8比設置其他過濾器都好
列表action
package com.test.action.user;
import java.util.Map;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.test.service.UserService;
public class ListUserAction extends ActionSupport
{
private UserService service;
public UserService getService()
{
return service;
}
public void setService(UserService service)
{
this.service = service;
}
@SuppressWarnings("unchecked")
@Override
public String execute() throws Exception
{
Map request = (Map) ActionContext.getContext().get("request");
request.put("list", service.findAll());
return SUCCESS;
}
}
顯示頁面：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

</s:iterator>
</table>
</body>

配置listaction：和spring見上面
校驗框架：第一種配置，校驗框架
SaveUserAction校驗，建立SaveUserAction-validation.xml文件，如果是屬性校驗，就用SaveUserAction-屬性名-validation.xml
