(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:
1
2 <servlet>
3 <servlet-name>SpringContextServlet</servlet-name>
4 <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
5 <load-on-startup>1</load-on-startup>
6 </servlet>
7
我的整个web.xml象这样:
java代码:
1
2 <?xml version="1.0" encoding="UTF-8"?>
3 <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

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:
1
2 <?xml version="1.0" encoding="UTF-8"?>
3 <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

83 </beans>
84
85
3.做DAO代码,
java代码:
1
2 package infoweb.dao;
3
4 import java.util.List;
5 import java.util.Iterator;
6
7 import infoweb.pojo.Board;
8
9
10 import net.sf.hibernate.HibernateException;
11 import net.sf.hibernate.Query;
12 import net.sf.hibernate.Session;
13
14 import org.springframework.orm.hibernate.HibernateCallback;
15 import org.springframework.orm.hibernate.support.HibernateDaoSupport;
16
17

26
27
28 public class BoardTreeDAOImpl extends HibernateDaoSupport implements

30
31
32 /**

39
40 /**

121 /**

150 Board parent = (Board) getHibernateTemplate().load(Board.class,child.getParentId());
151 return parent;
152 } 153 } 154
155
4.做service层代码
java代码:
1
2 package infoweb.service;
3
4 import java.util.List;
5 import java.util.Iterator;
6 import infoweb.dao.BoardTreeDAOImpl;
7 import infoweb.dao.IBoardTreeDAO;
8 import infoweb.pojo.Board;
9 import infoweb.exception.BoardException;
10 import net.sf.hibernate.HibernateException;
11
12 /**

16 * <p>Company: </p>
17 * @author 段洪杰
18 * @version 1.0
19 */
20 public class BoardServiceSpringImpl implements IBoardService {
...}
21
22 private IBoardTreeDAO boardTreeDAO;
23
24 public BoardServiceSpringImpl() {
...}
25 super();
26 } 27
28 /**
29 * 取所有roots版块
30 * @return Iterator
31 */
32 public Iterator getRoots() throws BoardException {
...}
33 Iterator roots = null;
34 try {
...}
35 roots = boardTreeDAO.getRoots();
36 } catch (Exception ex) {
37 throw new BoardException("取ROOT版块时出错! " + ex.toString());
38 } 39 return roots;
40 } 41
42 /**
43 * 增加Root新版块
44 * @param board Board
45 */
46 public void setRoot(Board board) throws BoardException {

48 boardTreeDAO.setRoot(board);
49 } catch (Exception ex) {
50 throw new BoardException("增加ROOT版块时出错! " + ex.toString());
51 } 52 } 53
54 /**
55 * 删除版块 (包含下级版块)
56 * @param board Board
57 */
58 public void removeBoard(Board board) throws BoardException {
...}
59 try {
...}
60 boardTreeDAO.deleteBranch(board);
61 } catch (Exception ex) {
62 throw new BoardException("删除版块时出错! " + ex.toString());
63 } 64 } 65
66 /**
67 *
68 * @return IBoardTreeDAO
69 */
70 public IBoardTreeDAO getBoardTreeDAO() {
...}
71 return boardTreeDAO;
72 } 73
74 /**
75 *
76 * @param boardTreeDAO IBoardTreeDAO
77 */
78 public void setBoardTreeDAO(IBoardTreeDAO boardTreeDAO) {
...}
79 this.boardTreeDAO = boardTreeDAO;
80 } 81
82 } 83
84
5.做ACTION的父类
java代码:
1
2 package infoweb.web;
3
4
5 import javax.servlet.ServletContext;
6 import org.apache.struts.action.Action;
7 import org.apache.struts.action.ActionServlet;
8 import org.springframework.web.context.WebApplicationContext;
9 import org.springframework.web.context.support.WebApplicationContextUtils;
10
11 import infoweb.service.IBoardService;
12
13
14 /**
15 * <p>Title: </p>
16 * <p>Description: </p>
17 * <p>Copyright: Copyright (c) 2004</p>
18 * <p>Company: </p>
19 * @author 段洪杰
20 * @version 1.0
21 */
22
23 public class BaseAction extends Action {
...}
24
25 private IBoardService boardService;
26
27 public void setServlet(ActionServlet actionServlet) {
...}
28 super.setServlet(actionServlet);
29 ServletContext servletContext = actionServlet.getServletContext();
30 WebApplicationContext wac =
31 WebApplicationContextUtils.getRequiredWebApplicationContext(
32 servletContext);
33 this.boardService = (IBoardService) wac.getBean("boardService");
34 } 35
36 protected IBoardService getBoardService() {
...}
37 return boardService;
38 } 39
40 } 41
42
6.做action类
java代码:
1
2 package infoweb.web;
3
4 import infoweb.pojo.Board;
5 import org.apache.commons.beanutils.PropertyUtils;
6 import org.apache.struts.action.*;
7 import org.apache.log4j.Logger;
8 import javax.servlet.http.*;
9 import java.util.Iterator;
10 import java.util.Date;
11
12 /**
13 * <p>Title: </p>
14 * <p>Description: </p>
15 * <p>Copyright: Copyright (c) 2004</p>
16 * <p>Company: </p>
17 * @author 段洪杰
18 * @version 1.0
19 */
20
21
22 public class SetBoardAction extends BaseAction {
...}
23
24 private static Logger log = Logger.getLogger(SetBoardAction.class);
25
26 public ActionForward execute(ActionMapping actionMapping,
27 ActionForm actionForm,
28 HttpServletRequest httpServletRequest,
29 HttpServletResponse httpServletResponse) throws
30 Exception {
...}
31
32 // SessionBean sessionBean = (SessionBean) httpServletRequest.getSession().getAttribute("sessionBean");
33 BoardForm boardForm = (BoardForm) actionForm;
34 //String backURL = httpServletRequest.getHeader("Referer");
35 /*
36 if (sessionBean==null||!sessionBean.getIsLogon()) {
37 httpServletRequest.setAttribute("message", "系统超时,或者没有登录 .返回重新登录!");
38 httpServletRequest.setAttribute("locationFile",
39 "location='index.jsp';");
40 return actionMapping.findForward("message");
41 }
42 */
43 Board board = new Board();
44 boardForm.setCreateDate(new Date());
45 PropertyUtils.copyProperties(board, boardForm);
46 getBoardService().setRoot(board);
47
48 httpServletRequest.setAttribute("message", "版块信息录入完成!");
49 httpServletRequest.setAttribute("locationFile",
50 "<A HREF=\"javascript:history.back()\">返回</A>");
51 return (actionMapping.findForward("success"));
52 } 53
54 } 55
