Struts+spring+hibernate学习笔记

(快刀浪子原创)下面是我学习Struts+spring+hibernate的笔记.

1.WEB.XML的配置:
首先在web.xml中加入:

代码

<servlet>
  <servlet-name>SpringContextServletservlet-name>
  <servlet-class>org.springframework.web.context.ContextLoaderServletservlet-class>
  <load-on-startup>1load-on-startup>
servlet>

<script>render_code();</script>

我的整个web.xml象这样:

代码

<!---->xml version="1.0" encoding="UTF-8"?>
<!---->>
<web-app>
  <display-name>info_webdisplay-name>
  <context-param>
    <param-name>contextConfigLocationparam-name>

2.spring配置
配置文件为applicationContext-hibernate.xml,在此配置文件中,配了POJO层,商业逻辑层,DAO层,和事务管理

代码

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

<beans>
    <!---->

    <!---->

    <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

<script>render_code();</script>

 

3.做DAO代码,

代码

package infoweb.dao;

import java.util.List;
import java.util.Iterator;

import infoweb.pojo.Board;

import net.sf.hibernate.HibernateException;
import net.sf.hibernate.Query;
import net.sf.hibernate.Session;

import org.springframework.orm.hibernate.HibernateCallback;
import org.springframework.orm.hibernate.support.HibernateDaoSupport;

  }

    return parent.getChildren().iterator();
  }

     */
    Board parent = (Board) getHibernateTemplate().load(Board.class, parentid);
    int count = parent.getChildren().size();
    return count;
  }

  /**
   * 存子叶
   * @param parentLeaf Leaf
   */
  public void setChild(Board board, String parentid) {
    board.setParentId(parentid);
    getHibernateTemplate().save(board);
  }

  /**
   *
   * 删除该叶和它的子叶
   * @param board Board
   */
  public void deleteBranch(Board board) {
      getHibernateTemplate().delete(board);
  }

  /**

  public Board getParentByChild(Board child) {
    String parentId = child.getParentId();    <li class="al
