S2SH 第一次整合的經歷

好不容易把S2SH整合到了一塊兒記下來之後用到了直接複製粘貼。。。 mysql

第一步：定義了各類model 實現getter()和setter()方法以及配置name.hbm.xml web

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" > spring

<hibernate-mapping package="com.yang.model">
<class name="User" table="user_table">
  <id name="id" column="user_id">
   <generator class="identity" />
  </id>
  <property name="username" type="string" not-null="true" length="50" unique="true" />
  <property name="password" type="string" not-null="true" length="50" />
  <property name="email" type="string" length="100" />
  <property name="name" type="string" length="100" />
  <property name="phone" type="string" length="50" />
  <property name="date" type="string" length="50" />
  <set name="articles">
   <key column="article_id" />
   <one-to-many class="Article" />
  </set>
  <set name="comments">
   <key column="comment_id" />
   <one-to-many class="Comment" />
  </set>
  <set name="messages">
   <key column="message_id" />
   <one-to-many class="Message" />
  </set>
</class>
</hibernate-mapping> sql

第二步：定義了DAO接口裏面定義了針對model的各類操做方法數據庫

這是我定義的一個UserDAO： apache

public interface UserDAO {
         void addUser(User user);
         User getUserById(int id);
         void updateUser(User user);
         String login(String username,String password );
         User getUserByName(String username);
} session

第三部：定義DaoImpl類這個類要繼承了抽象類 HibernateDaoSupport 而且實現剛剛定義的DAO接口 app

UserDaoImpl的實現代碼： jsp

package com.yang.daoImpl; ide

import org.hibernate.Query;
import org.hibernate.Session;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.yang.dao.UserDAO;
import com.yang.model.User;

public class UserDaoImpl extends HibernateDaoSupport implements UserDAO {

@Override
public void addUser(User user) {
  System.out.println(user.getUsername());
  System.out.println(user.getPassword());
  getHibernateTemplate().save(user);
}

@Override
public User getUserById(int id) {
getHibernateTemplate().get(User.class, id);
return null;
}

@Override
public void updateUser(User user) {
getHibernateTemplate().save(user);

}

@Override
public String login(String username,String password) {
  Session session = getSession();
  String hql="select password from User where username=?";
  Query query = session.createQuery(hql);
  query.setParameter(0,username);
  String str = (String) query.uniqueResult();
  if(password.equals(str))
   return "success";
  else
   return "input";
}

@Override
public User getUserByName(String username) {
  Session session = getSession();
  String hql="select from User where username=?";
  Query query = session.createQuery(hql);
  query.setParameter(0,username);
  return (User)query.uniqueResult();
}

}

第四步：定義Action類繼承ActionSupport 而且在這個Action的內部咱們要定義好以前說過DaoImpl 而且要有相對應的get和set方法這樣才能在下一步經過spring注入到action。

第五步：配置.xml文件

首先是web.xml

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>    //spring的配置

<filter>
<filter-name>struts-cleanup</filter-name>
<filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>
</filter>

<filter>
<filter-name>sitemesh</filter-name>
<filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
</filter>

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts-cleanup</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>sitemesh</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

用到了sitemesh 因此在配置文件裏面影響到了struts的配置不用的話能夠直接和前面的clean-up一塊兒刪掉

而後配置applicationContext.xml

<?xml version="1.0" encoding="GBK"?>

  </property>
