</PRE><BR>好了，数据持久层（dao）开发好了，按顺序，现在应该开发业务层了， <BR>新建包com.test.service
<BR>建类UserService.java <BR>代码： <BR><PRE class=java name="code">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);
}
</PRE>这是一个接口类 <BR>然后写实现类 <BR>新建包 <BR>com.test.service.impl <BR>建类
<BR>UserServiceImpl.java <BR><PRE class=java name="code">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;
}
//服务层的方法
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);
}
}
</PRE><BR><BR>业务和持久层都开发好了，现在我们回到控制层action <BR>修改action的代码如下： <BR><PRE class=java name="code">package com.test.action.user;
import com.opensymphony.xwork2.ActionSupport;
import com.test.bean.User;
import com.test.service.*;
public class SaveUserAction extends ActionSupport {
private User user;
private UserService service;
public UserService getService() {
return service;
}
public void setService(UserService service) {
this.service = service;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
@Override
public String execute() throws Exception
{
this.service.save(this.user);
return SUCCESS;
}
}
</PRE><BR>修改struts.xml <BR>如下 <BR><PRE class=xml name="code"><?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">
<struts>
<package name="user" extends="struts-default">
<action name="saveUser" class="saveUserAction">
<result name="success" type="redirect">listUser.action</result>
<result name="input">/saveUser.jsp</result>
</action>
</package>
</struts>
</PRE><BR><BR>至此，我们已经开发好了一个典型的mvc项目，现在的任务是将strust2和hibernate都放入spring容器管理，
<BR>现在我们的项目结构如下： <BR><BR><IMG
