Struts+spring+hibernate学习笔记!分类：hibernatestrutsspring2005-01-09 10:59509人阅读评论(0)收藏举报(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:java代码: SpringContextServlet org.springframework.web.context.ContextLoaderServlet 1 我的整个web.xml象这样:java代码: info_web contextConfigLocation /WEB-INF/applicationContext-hibernate.xml SetCharacterEncoding iclass.util.SetEncodingFilter encoding GBK FilterRedirector org.apache.cactus.server.FilterTestRedirector SetCharacterEncoding /* FilterRedirector /FilterRedirector SpringContextServlet org.springframework.web.context.ContextLoaderServlet 1 ServletRedirector org.apache.cactus.server.ServletTestRedirector JspRedirector /jspRedirector.jsp action org.apache.struts.action.ActionServlet config /WEB-INF/struts-config.xml debug 2 application ApplicationResources 2 ServletRedirector /ServletRedirector JspRedirector /JspRedirector action *.do index.jsp /tags/struts-nested /WEB-INF/struts-nested.tld /WEB-INF/struts-bean.tld /WEB-INF/struts-bean.tld /WEB-INF/struts-html.tld /WEB-INF/struts-html.tld /WEB-INF/struts-logic.tld /WEB-INF/struts-logic.tld /WEB-INF/struts-tiles.tld /WEB-INF/struts-tiles.tld /WEB-INF/struts-nested.tld /WEB-INF/struts-nested.tld 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java代码: org.gjt.mm.mysql.Driver jdbc:mysql:/localhost:3306/info_web?useUnicode=true&characterEncoding=GBK root 123456 infoweb/pojo/Answer.hbm.xml infoweb/pojo/Board.hbm.xml infoweb/pojo/Image.hbm.xml infoweb/pojo/Info.hbm.xml net.sf.hibernate.dialect.MySQLDialect true true PROPAGATION_REQUIRED,readOnly,-BoardException PROPAGATION_REQUIRED,-BoardException PROPAGATION_REQUIRED,-BoardException PROPAGATION_REQUIRED,-BoardException 3.做DAO代码,java代码:packageinfoweb.dao;importjava.util.List;importjava.util.Iterator;importinfoweb.pojo.Board;importnet.sf.hibernate.HibernateException;importnet.sf.hibernate.Query;importnet.sf.hibernate.Session;importorg.springframework.orm.hibernate.HibernateCallback;importorg.springframework.orm.hibernate.support.HibernateDaoSupport;/* Title: 版块分类DAOImpl* Description: 用树型结构实现* Copyright: Copyright (c) 2004* Company: * author 段洪杰* version 1.0*/publicclassBoardTreeDAOImplextendsHibernateDaoSupportimplements IBoardTreeDAO/* * 构造函数 */publicBoardTreeDAOImpl() super();/* * 通过ID取得版块 * param id String * return Board */publicBoard getBoardById(Stringid) Board board =(Board)getHibernateTemplate().load(Board.class, id); returnboard;/* * 取根叶 * return Iterator */publicIteratorgetRoots()throwsHibernateException StringqueryString = select board from Board as board where board.parentId=rootorder by board.iddesc; Listroots = getHibernateTemplate().find(queryString); returnroots.iterator();/* * 存根叶 * param board Board */publicvoidsetRoot(Board board) board.setParentId(root); getHibernateTemplate().save(board);/* * 取子叶 * param parentid String * return List */publicIteratorgetChildren(Stringparentid) /* String queryString = select board as Board where board.parent_id=parentid order by board.id desc; List children = getHibernateTemplate().find(queryString); return children; */ Board parent =(Board)getHibernateTemplate().load(Board.class, parentid); returnparent.getChildren().iterator();/* * 取子叶数 * param parentid String * return int */publicintgetChildrenCount(Stringparentid) /* String queryString = select count(*) Board where board.parent_id=parentid order by board.id desc; List children = getHibernateTemplate().find(queryString); int count = (Integer) children.iterator().next().intValue(); return count; */ Board parent =(Board)getHibernateTemplate().load(Board.class, parentid); intcount = parent.getChildren().size(); returncount;/* * 存子叶 * param parentLeaf Leaf */publicvoidsetChild(Board board,Stringparentid) board.setParentId(parentid); getHibernateTemplate().save(board);/* * * 删除该叶和它的子叶 * param board Board */publicvoiddeleteBranch(Board board) getHibernateTemplate().delete(board);/* * 根据子叶得到父叶 * param child Board * return Board */publicBoard getParentByChild(Board child) StringparentId = child.getParentId(); Board parent =(Board)getHibernateTemplate().load(Board.class, parentId); returnparent;/* * 通过子ID得到父叶 * param id String * return Board */publicBoard getParentByChildId(Stringid) Board child =(Board)getHibernateTemplate().load(Board.class, id); Board parent =(Board)getHibernateTemplate().load(Board.class,child.getParentId(); returnparent;4.做service层代码java代码:packageinfoweb.service;importjava.util.List;importjava.util.Iterator;importinfoweb.dao.BoardTreeDAOImpl;importinfoweb.dao.IBoardTreeDAO;importinfoweb.pojo.Board;importinfoweb.exception.BoardException;importnet.sf.hibernate.HibernateException;/* Title: * Description: * Copyright: Copyright (c) 2004* Company: * author 段洪杰* version 1.0*/publicclassBoardServiceSpringImplimplementsIBoardService privateIBoardTreeDAO boardTreeDAO; publicBoardServiceSpringImpl() super(); /* * 取所有roots版块 * return Iterator */ publicIteratorgetRoots()throwsBoardException Iteratorroots =null; try roots = boardTreeDAO.getRoots(); catch(Exceptionex) thrownewBoardException(取ROOT版块时出错! + ex.toString(); returnroots; /* * 增加Root新版块 * param board Board */ publicvoidsetRoot(Board board)throwsBoardException try boardTreeDAO.setRoot(board); catch(Exceptionex) thrownewBoardException(增加ROOT版块时出错! + ex.toString(); /* * 删除版块 (包含下级版块) * param board Board */ publicvoidremoveBoard(Board board)throwsBoardException try boardTreeDAO.deleteBranch(board); catch(Exceptionex) thrownewBoardException(删除版块时出错! + ex.toString(); /* * * return IBoardTreeDAO */ publicIBoardTreeDAO getBoardTreeDAO() returnboardTreeDAO; /* * * param boardTreeDAO IBoardTreeDAO */ publicvoidsetBoardTreeDAO(IBoardTreeDAO boardTreeDAO) this.boardTreeDAO= boardTreeDAO; 5.做ACTION的父类java代码:packageinfoweb.web;importjavax.servlet.ServletContext;importorg.apache.struts.action.Action;importorg.apache.struts.action.ActionServlet;importorg.springframework.web.context.WebApplicationContext;importorg.springframework.web.context.support.WebApplicationContextUtils;importinfoweb.service.IBoardService;/* Title: * Description: * Copyright: Copyright (c) 2004* Company: * author 段洪杰* version 1.0*/publicclassBaseActionextendsActionprivateIBoardService boardService;publicvoidsetServlet(ActionServlet actionServlet) super.setServlet(actionServlet); ServletContext servletContext = actionServlet.getServletContext(); WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext( servletContext); this.boardService=(IBoardService)wac.getBean(boardService);protectedIBoardService getBoardService() returnboardService;6.做action类java代码:packageinfoweb.web;importinfoweb.pojo.Board;mons.beanutils.PropertyUtils;importorg.apache.struts.action.*;importorg.apache.log4j.Logger;importjavax.servlet.http.*;importjava.util.Iterator;importjava.util.Date;/* Title: * Description: * Copyright: Copyright (c) 2004* Company: * author 段洪杰* version 1.0*/publicclassSetBoardActionextendsBaseAction privatestaticLogger log = Logger.getLogger(SetBoardAction.class);
