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:

   <?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                    http://www.springframework.org/schema/aop

  　<bean id="userManageService" class="liao.Service.impl.UserManageServiceImpl">

  </property>

 </bean>

<aop:config>

  <aop:pointcut id="serviceOperation" expression="execution(* edu.jlu.fuliang.Service.impl.*ServiceImpl.*(..))"/>

  <aop:advisor pointcut-ref="serviceOperation" advice-ref="txAdvice"/>

 </aop:config> 

 

 <tx:advice id="txAdvice">

  <tx:attributes>

   <tx:method name="get*" read-only="true"/>

   <tx:method name="*"/>

  </tx:attributes>

 </tx:advice>

 

  <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">

  <property name="sessionFactory">

   <ref bean="sessionFactory"/>

  </property>

 </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>

10 web.xml

  <?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4"
