(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:
我的整个web.xml象这样:
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
3.做DAO代码,
4.做service层代码
5.做ACTION的父类
6.做action类
1.WEB.XML的配置:
首先在web.xml中加入:
<servlet> <servlet-name>SpringContextServlet</servlet-name> <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet>
我的整个web.xml象这样:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <display-name>info_web</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext-hibernate.xml</param-value> </context-param> <filter> <filter-name>SetCharacterEncoding</filter-name> <filter-class>iclass.util.SetEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>GBK</param-value> </init-param> </filter> <filter> <filter-name>FilterRedirector</filter-name> <filter-class>org.apache.cactus.server.FilterTestRedirector</filter-class> </filter> <filter-mapping> <filter-name>SetCharacterEncoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter-mapping> <filter-name>FilterRedirector</filter-name> <url-pattern>/FilterRedirector</url-pattern> </filter-mapping> <servlet> <servlet-name>SpringContextServlet</servlet-name> <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet> <servlet-name>ServletRedirector</servlet-name> <servlet-class>org.apache.cactus.server.ServletTestRedirector</servlet-class> </servlet> <servlet> <servlet-name>JspRedirector</servlet-name> <jsp-file>/jspRedirector.jsp</jsp-file> </servlet> <servlet> <servlet-name>action</servlet-name> <servlet-class>org.apache.struts.action.ActionServlet</servlet-class> <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param> <init-param> <param-name>debug</param-name> <param-value>2</param-value> </init-param> <init-param> <param-name>application</param-name> <param-value>ApplicationResources</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>ServletRedirector</servlet-name> <url-pattern>/ServletRedirector</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>JspRedirector</servlet-name> <url-pattern>/JspRedirector</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <taglib> <taglib-uri>/tags/struts-nested</taglib-uri> <taglib-location>/WEB-INF/struts-nested.tld</taglib-location> </taglib> <taglib> <taglib-uri>/WEB-INF/struts-bean.tld</taglib-uri> <taglib-location>/WEB-INF/struts-bean.tld</taglib-location> </taglib> <taglib> <taglib-uri>/WEB-INF/struts-html.tld</taglib-uri> <taglib-location>/WEB-INF/struts-html.tld</taglib-location> </taglib> <taglib> <taglib-uri>/WEB-INF/struts-logic.tld</taglib-uri> <taglib-location>/WEB-INF/struts-logic.tld</taglib-location> </taglib> <taglib> <taglib-uri>/WEB-INF/struts-tiles.tld</taglib-uri> <taglib-location>/WEB-INF/struts-tiles.tld</taglib-location> </taglib> <taglib> <taglib-uri>/WEB-INF/struts-nested.tld</taglib-uri> <taglib-location>/WEB-INF/struts-nested.tld</taglib-location> </taglib> </web-app>
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
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <!-- ========================= Start of PERSISTENCE DEFINITIONS ========================= --> <!-- Choose the dialect that matches your "dataSource" definition --> <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName"> <value>org.gjt.mm.mysql.Driver</value> </property> <property name="url"> <value>jdbc:mysql://localhost:3306/info_web?useUnicode=true&characterEncoding=GBK</value> </property> <property name="username"> <value>root</value> </property> <property name="password"> <value>123456</value> </property> </bean> <bean id="mySessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean"> <property name="mappingResources"> <list> <value>infoweb/pojo/Answer.hbm.xml</value> <value>infoweb/pojo/Board.hbm.xml</value> <value>infoweb/pojo/Image.hbm.xml</value> <value>infoweb/pojo/Info.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">net.sf.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.cglib.use_reflection_optimizer">true</prop> </props> </property> <property name="dataSource"><ref bean="myDataSource"/></property> </bean> <!-- Transaction manager for a single Hibernate SessionFactory (alternative to JTA); --> <bean id="myTransactionManager" class="org.springframework.orm.hibernate.HibernateTransactionManager"> <property name="sessionFactory"><ref local="mySessionFactory"/></property> </bean> <!-- ***** Board SERVICE ***** --> <bean id="boardService" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> <property name="transactionManager"><ref local="myTransactionManager"/></property> <property name="target"><ref local="boardServiceSpring"/></property> <property name="transactionAttributes"> <props> <prop key="get*">PROPAGATION_REQUIRED,readOnly,-BoardException</prop> <prop key="set*">PROPAGATION_REQUIRED,-BoardException</prop> <prop key="modify*">PROPAGATION_REQUIRED,-BoardException</prop> <prop key="remove*">PROPAGATION_REQUIRED,-BoardException</prop> </props> </property> </bean> <!-- board primary business object implementation --> <bean id="boardServiceSpring" class="infoweb.service.BoardServiceSpringImpl"> <property name="boardTreeDAO"><ref local="boardTreeDAO"/></property> </bean> <!-- DAO board: Hibernate implementation --> <bean id="boardTreeDAO" class="infoweb.dao.BoardTreeDAOImpl"> <property name="sessionFactory"><ref local="mySessionFactory"/></property> </bean> <!-- DAO info: Hibernate implementation --> <bean id="infoDAO" class="infoweb.dao.InfoDAOImpl"> <property name="sessionFactory"><ref local="mySessionFactory"/></property> </bean> </beans>
3.做DAO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; /** * <p>Title: 版块分类DAOImpl</p> * <p>Description: 用树型结构实现</p> * <p>Copyright: Copyright (c); 2004</p> * <p>Company: </p> * @author 段洪杰 * @version 1.0 */ public class BoardTreeDAOImpl extends HibernateDaoSupport implements IBoardTreeDAO { /** * 构造函数 */ public BoardTreeDAOImpl(); { super();; } /** * 通过ID取得版块 * @param id String * @return Board */ public Board getBoardById(String id); { Board board = (Board); getHibernateTemplate();.load(Board.class, id);; return board; } /** * 取根叶 * @return Iterator */ public Iterator getRoots(); throws HibernateException { String queryString = "select board from Board as board where board.parentId='root' order by board.id desc"; List roots = getHibernateTemplate();.find(queryString);; return roots.iterator();; } /** * 存根叶 * @param board Board */ public void setRoot(Board board); { board.setParentId("root");; getHibernateTemplate();.save(board);; } /** * 取子叶 * @param parentid String * @return List */ public Iterator getChildren(String parentid); { /* 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);; return parent.getChildren();.iterator();; } /** * 取子叶数 * @param parentid String * @return int */ public int getChildrenCount(String parentid); { /* 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);; 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);; } /** * 根据子叶得到父叶 * @param child Board * @return Board */ public Board getParentByChild(Board child); { String parentId = child.getParentId();; Board parent = (Board); getHibernateTemplate();.load(Board.class, parentId);; return parent; } /** * 通过子ID得到父叶 * @param id String * @return Board */ public Board getParentByChildId(String id); { Board child = (Board); getHibernateTemplate();.load(Board.class, id);; Board parent = (Board); getHibernateTemplate();.load(Board.class,child.getParentId(););; return parent; } }
4.做service层代码
package infoweb.service; import java.util.List; import java.util.Iterator; import infoweb.dao.BoardTreeDAOImpl; import infoweb.dao.IBoardTreeDAO; import infoweb.pojo.Board; import infoweb.exception.BoardException; import net.sf.hibernate.HibernateException; /** * <p>Title: </p> * <p>Description: </p> * <p>Copyright: Copyright (c); 2004</p> * <p>Company: </p> * @author 段洪杰 * @version 1.0 */ public class BoardServiceSpringImpl implements IBoardService { private IBoardTreeDAO boardTreeDAO; public BoardServiceSpringImpl(); { super();; } /** * 取所有roots版块 * @return Iterator */ public Iterator getRoots(); throws BoardException { Iterator roots = null; try { roots = boardTreeDAO.getRoots();; } catch (Exception ex); { throw new BoardException("取ROOT版块时出错! " + ex.toString(););; } return roots; } /** * 增加Root新版块 * @param board Board */ public void setRoot(Board board); throws BoardException { try { boardTreeDAO.setRoot(board);; } catch (Exception ex); { throw new BoardException("增加ROOT版块时出错! " + ex.toString(););; } } /** * 删除版块 (包含下级版块); * @param board Board */ public void removeBoard(Board board); throws BoardException { try { boardTreeDAO.deleteBranch(board);; } catch (Exception ex); { throw new BoardException("删除版块时出错! " + ex.toString(););; } } /** * * @return IBoardTreeDAO */ public IBoardTreeDAO getBoardTreeDAO(); { return boardTreeDAO; } /** * * @param boardTreeDAO IBoardTreeDAO */ public void setBoardTreeDAO(IBoardTreeDAO boardTreeDAO); { this.boardTreeDAO = boardTreeDAO; } }
5.做ACTION的父类
package infoweb.web; import javax.servlet.ServletContext; import org.apache.struts.action.Action; import org.apache.struts.action.ActionServlet; import org.springframework.web.context.WebApplicationContext; import org.springframework.web.context.support.WebApplicationContextUtils; import infoweb.service.IBoardService; /** * <p>Title: </p> * <p>Description: </p> * <p>Copyright: Copyright (c); 2004</p> * <p>Company: </p> * @author 段洪杰 * @version 1.0 */ public class BaseAction extends Action { private IBoardService boardService; public void setServlet(ActionServlet actionServlet); { super.setServlet(actionServlet);; ServletContext servletContext = actionServlet.getServletContext();; WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext( servletContext);; this.boardService = (IBoardService); wac.getBean("boardService");; } protected IBoardService getBoardService(); { return boardService; } }
6.做action类
package infoweb.web; import infoweb.pojo.Board; import org.apache.commons.beanutils.PropertyUtils; import org.apache.struts.action.*; import org.apache.log4j.Logger; import javax.servlet.http.*; import java.util.Iterator; import java.util.Date; /** * <p>Title: </p> * <p>Description: </p> * <p>Copyright: Copyright (c); 2004</p> * <p>Company: </p> * @author 段洪杰 * @version 1.0 */ public class SetBoardAction extends BaseAction { private static Logger log = Logger.getLogger(SetBoardAction.class);; public ActionForward execute(ActionMapping actionMapping, ActionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse); throws Exception { // SessionBean sessionBean = (SessionBean); httpServletRequest.getSession();.getAttribute("sessionBean");; BoardForm boardForm = (BoardForm); actionForm; //String backURL = httpServletRequest.getHeader("Referer");; /* if (sessionBean==null||!sessionBean.getIsLogon();); { httpServletRequest.setAttribute("message", "系统超时,或者没有登录 .返回重新登录!");; httpServletRequest.setAttribute("locationFile", "location='index.jsp';");; return actionMapping.findForward("message");; } */ Board board = new Board();; boardForm.setCreateDate(new Date(););; PropertyUtils.copyProperties(board, boardForm);; getBoardService();.setRoot(board);; httpServletRequest.setAttribute("message", "版块信息录入完成!");; httpServletRequest.setAttribute("locationFile", "<A HREF=\"javascript:history.back();\">返回</A>");; return (actionMapping.findForward("success"););; } }
