struts 2+hibernate 3+spring基本套路小结

   任何东西都是有一定的套路和规律的,struts 2+hibernate 3+spring也一样,struts2 比struts1爽很多了,但目前唯一觉得不爽的
是struts2 居然没什么好的IDE工具去支持设计之,比如DW8,希望以后有所改进.
  这里,以一个简单的用户注册,登陆去说明这三者之间的简单组合关系,其他都可以按这样的去做:
1 建立domain层
   建立包domain,里面有个user.java
   public class User {
 private Long id;
 private String userName;
 private String password;
//getter,setter.....

2)建立user.hbm.xml
   省略
3) 建立dao层
　　　建立dao包，有userdao.java
    

import java.util.List;

import liao.domain.User;

public interface UserDAO {
 public User findById(long id);
 public void save(User user);
 public List<User>  findByUserNameAndPassword(String userName,String password);
 public List<User>  findByUserName(String userName);
}

4 建立userdaoimpl.java
   

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import liao.dao.UserDAO;
import liao.domain.User;

public class UserDAOImpl extends HibernateDaoSupport implements UserDAO{

 public User findById(long id) {
  return (User)getHibernateTemplate().get(User.class, id);
 }

 public List<User> findByUserName(String userName) {
  return getHibernateTemplate().find("from User where userName=?",new String[]{userName});
 }

 public List<User>  findByUserNameAndPassword(String userName, String password) {
  return getHibernateTemplate().find("from User where userName=? and password=?",new String[]{userName,password});
 }

 public void save(User user) {
  getHibernateTemplate().saveOrUpdate(user);
 }

}

5 建立sevrice层，建立好service包
import edu.jlu.fuliang.domain.User;

public interface UserManageService {
 public void register(User user);
 public boolean login(User user);
}

6 service的实现
　　

import java.util.List;

import  liao.Service.UserManageService;
import liao.dao.UserDAO;
import liao.domain.User;

public class UserManageServiceImpl implements UserManageService{

 private UserDAO userDAO;

 public boolean login(User user) {
  List<User> users = userDAO.findByUserNameAndPassword(user.getUserName(), user.getPassword()) ;
  return users.size() != 0;
 }

  public void register(User user) {
  userDAO.save(user);
 }
 
 public UserDAO getUserDAO() {
  return userDAO;
 }

 public void setUserDAO(UserDAO userDAO) {
  this.userDAO = userDAO;
 }

}

7 之后就是struts2的action层了
　　首先是注册registeraction.java
  

import com.opensymphony.xwork2.ActionSupport;

import liao.Service.UserManageService;
import liao.domain.User;

public class RegisterAction extends ActionSupport{
 private User user;
 private UserManageService userManageService;
 
 public String execute()throws Exception{
    userManageService.register(user);
    return SUCCESS;
 }
 
 public User getUser() {
  return user;
 }
 
 public void setUser(User user) {
  this.user = user;
 }
 
 public void setUserManageService(UserManageService userManageService) {
  this.userManageService = userManageService;
 }
}

   登陆的loginaction.java
 

public class LoginAction extends ActionSupport{
 private User user;
 private UserManageService userManageService;
 
 public String execute()throws Exception{
  if(userManageService.login(user)){
   ServletActionContext.getContext().getSession().put("user",user);
   return SUCCESS;
  }
  return LOGIN;
 }

 public User getUser() {
  return user;
 }

 public void setUser(User user) {
  this.user = user;
 }

 public void setUserManageService(UserManageService userManageService) {
  this.userManageService = userManageService;
 }
}

8 配置好各类的applcaition.xml,建议分开几个来配置，避免全部放在一个xml
  application-db.xml：比较传统，不说了
　application-dao.xml:
  <bean id="userDAO" class="liao.dao.impl.UserDAOImpl">
  <property name="sessionFactory">
   <ref bean="sessionFactory"/>
  </property>
 </bean>
application-service.xml:

 </bean>
9 struts.xml
  <action name="login" class="loginAction">
     <result name="success">/uploadSong.jsp</result>
     <result name="login">/login.jsp</result>
  </action>
  
  <action name="register" class="registerAction">
   <result name="success" type="redirect-action">listSong</result>
   <result name="input">/register.jsp</result>
  </action>
