SSH整合應(yīng)用+Jquary+Flexigrid實現(xiàn)表格數(shù)據(jù)顯示

1、SSH整合：學(xué)習(xí)過程中的一個實例，麻雀雖小五臟俱全！應(yīng)用到了 SSH整合及Jquery框架flexigrid插 件，實現(xiàn)列表數(shù)據(jù)顯示。以下是主要整合配置和JAVA源碼（帶注釋）一、導(dǎo)入所有需要的Jar包二、Web.xml 配置strutsfilterorg.apache.struts2.dispatcher.ng.filter.StrutsPrepa reAndExecuteFilterstrutsfilter/*contextConfigLocationclasspath:applicationContext-*.xmlorg.springframework.web.context.Cont

2、extLoaderListenerindex.jsp三、Struts2配置Struts.xml package namespace=/user name=demo-user extends= json-default /WEB-INF/demo/user_list.jsp 四、src 下三 個 XML : ( applicationContext-database.xml; applicationContext-service.xml;applicationContext-dao.xml)分別為配置的數(shù)據(jù)源、服務(wù)層、DAO層其內(nèi)容如下：applicationContext-database.x

3、ml org.hibernate.dialect.MySQLDialect 路徑 +/User.hbm.xml applicationContext-service.xmlapplicationContext-dao.xmlbean id=userDao class = 引入dao層實現(xiàn)類 五、Action 類package 火火火火火；導(dǎo)包火火火火火火火火火火；public class UserAction extends BaseAction (private static final long serialVersionUID = 1L;private Integer page; / 當(dāng)

4、前頁private Integer totle; /共幾頁private Integer rp;/ 每頁顯示條目private List users;/注入業(yè)務(wù)private UserService userService;private HttpServletResponse response;public void getUserList() throws Exception (try (System.out.println(xxxxxxxxxxxxxxxxxxx);users = userService.findAll();response = ServletActionContext.

5、getResponse();response.setContentType(application/json;charset=GBK); String jsonStr = getJsonStr(users);response.getWriter().write(jsonStr); catch (RuntimeException e) ( e.printStackTrace();throw new Exception(e);public String getJsonStr(List list) (Map map = new HashMap();map.put( page , page); / 當(dāng)

6、前頁數(shù)map.put( total , list.size(); / 總記錄數(shù)List rows = new ArrayList();for (Iterator iterator = list.iterator(); iterator.hasNext();) (User user = (User) iterator.next();Map cellMap = new HashMap();JSONObject json = new JSONObject(); json.put(id, user.getId();json.put(name, user.getName();cellMap.put(id

7、, user.getId(); cellMap.put(cell, json);rows.add(cellMap); map.put(rows, rows); JSONObject object = JSONObject. fromObject (map); return object.toString();/*屬性訪問方法*/*六、JSP 頁面使用 JQuery+flexigrid FlexiGrid Demo var a=document.body.clientHeight-143;var b=document.body.clientWidth-3;var clientScreen = window.screen.width;var one,two;one = b*0.03;two = b*0.17;$(#flex1).flexigrid( (url: ./user/getUsers.action, dataType: json, colModel :(display: ID, name : id, width : one, sortable : false, align: left,(display:姓名, name : name, width : two, sortable : true, align: left,sortname: id,
