struts 2+hibernate 3+spring基本套路小结

Userxmlspring虚拟化云计算

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" 

 xmlns:aop="http://www.springframework.org/schema/aop" 

 xmlns:tx="http://www.springframework.org/schema/tx" 

 xsi:schemaLocation="http://www.springframework.org/schema/beans 

​​                     http://www.springframework.org/schema/beans/spring-beans.xsd 
​​                     http://www.springframework.org/schema/tx 

                     http://www.springframework.org/schema/tx/spring-tx.xsd 

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

                     http://www.springframework.org/schema/aop/spring-aop.xsd">

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

   <property name="userDAO">

    <ref bean="userDAO"/>

   </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" 

  xmlns="http://java.sun.com/xml/ns/j2ee" 

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