/***注，本文的代码已经上传到阿里云code，svn地址：http://code.taobao.org/svn/JdevAppdemo/ 但是需要我添加你，有兴趣的可以私聊我 oracle数据库表想要的我也可以发*****/

公司最近在用ssh框架开发系统，好奇拿来玩玩。本着我菜，你比我还菜的不要脸精神，跟大家分享一下~

首先介绍一下公司框架的基本结构：

省略了dao，数据库持久层（就是操作底层数据的方法）操作放在了service中

项目是用maven管理的。

model创建oracle数据库表的实体，Service中进行后台操作，例如数据库数据的保存，修改，删除操作等，Action进行前台的信息操作，Form进行前台的数据交换。

好了，最终效果还好吧，哈哈-----看到点希望之后，就开始从头实践一下~

我来用controlSyntax（语法控制）这个对象来举例，其实这是一个公司自己开发的一个小工具系统，主要用来向数据库录入一些数据（太复杂的我也不能详细解释，毕竟涉及到保密，就理解大概意思就好--这个系统是向数据库存数据的）

第一步：（正常的流程第一步应该是创建数据表结构，生成model，由于现在的辅助工具，IDE插件比较强大，所以在这里先不做说明，有兴趣的可以自行google）

创建文件：主要创建的文件有

ControlSyntaxOperService.java（接口） impl-----ControlSyntaxOperServiceImpl.java（实现类）

| |

抽象方法先写好

要实现的功能有：查询方法，普通查询方法，

分页查询方法，新增/修改方法，

删除方法

ControlSyntaxAction.java（Action类） form------ControlSyntaxForm.java（Form类）

controlSyntaxList.jsp controlSyntaxOperPage.jsp

第二步：写代码，哈哈终于开始了~~

先写service接口抽象方法

public interface ControlSyntaxOperService {public List<ControlSyntax> queryControlSyntaxOfList(ControlSyntax controlSyntax);public PageInfo queryControlSyntaxOfPage(ControlSyntax controlSyntax,PageInfo pageInfo);public ControlSyntax getControlSyntax(String Id);public String operControlSyntax(ControlSyntax controlSyntax);public void deleteControlSyntax(String id);}

写接口实现：

@Service(value="controlSyntaxService")public class ControlSyntaxOperServiceImpl implements ControlSyntaxOperService{@Autowiredprotected BaseDao baseDao;private Object queryControlSyntaxOfCommon(ControlSyntax controlSyntax, PageInfo pageInfo) {              StringBuffer sqlBuf = new StringBuffer(32);   sqlBuf.append("From " + ControlSyntax.ENTITY_NAME )         .append(" WHERE 1=1 ")         .append(" /~ AND name like '%' || :name || '%' ~/ ");      Map<String, Object> params = new HashMap<String, Object>();   if(controlSyntax == null){   controlSyntax = new ControlSyntax();   }   params.put("name", controlSyntax.getName());      return null == pageInfo ? baseDao.queryForList(sqlBuf.toString(), params)    : baseDao.queryForPage(sqlBuf.toString(), params, pageInfo);}//普通查询方法public List<ControlSyntax> queryControlSyntaxOfList(ControlSyntax controlSyntax) {return (List<ControlSyntax>)queryControlSyntaxOfCommon(controlSyntax, null);}//分页查询方法public PageInfo queryControlSyntaxOfPage(ControlSyntax controlSyntax, PageInfo pageInfo) {return (PageInfo) this.queryControlSyntaxOfCommon(controlSyntax, pageInfo);}//根据id获取详情--注意方法名get开头public ControlSyntax getControlSyntax(String id) {Assert.notNull(id, "主键不为空");ControlSyntax controlSyntax = (ControlSyntax) baseDao.get(ControlSyntax.class, id);return controlSyntax;}//新增，修改方法，当id为空时新增，不为空时修改public String operControlSyntax(ControlSyntax controlSyntax) {String id = controlSyntax.getId();if(StringUtils.isEmpty(id)){baseDao.save(controlSyntax);}else{ControlSyntax dbControlSyntax = (ControlSyntax) baseDao.get(ControlSyntax.class, id);BeanCopyUtil.copyBeanProperties(controlSyntax,dbControlSyntax);baseDao.update(controlSyntax);}return "";}//删除方法public void deleteControlSyntax(String id){Assert.notNull(id,"主键不为空");ControlSyntax controlSyntax = (ControlSyntax) baseDao.get(ControlSyntax.class, id);baseDao.delete(controlSyntax);}}

接下来是Action方法：

@Controllerpublic class ControlSyntaxAction extends ZPageManageBaseAction{@AutowiredControlSyntaxOperService controSyntaxOperService;protected String getPageFolder() {return "controlSyntax";}//进入列表方法@RequestMapping(value = "zpage/controlSyntaxList")public String controlSyntaxList(ControlSyntaxForm form,ModelMap modelMap){//分页显示信息PageInfo pageInfo = controSyntaxOperService.queryControlSyntaxOfPage(form.getControlSyntax(), form.getPageInfo());modelMap.put("pageInfo", pageInfo);//翻译（用枚举类）Map<String,EnumSyntaxType> enumSyntaxTypeMap = EnumSyntaxType.obtainValueMap();modelMap.put("enumSyntaxTypeMap", enumSyntaxTypeMap);return super.wrapPage("controlSyntaxList");}//新增、编辑操作@RequestMapping(value="zpage/controlSyntaxOperPage")public String controlSyntaxOperPage(ControlSyntaxForm form,ModelMap modelMap){//调用serviceMap<String,EnumSyntaxType> enumSyntaxTypeMap = EnumSyntaxType.obtainValueMap();modelMap.put("enumSyntaxTypeMap", enumSyntaxTypeMap);String id = form.getId();if(StringUtils.isEmpty(id)){ControlSyntax controlSyntax = new ControlSyntax();modelMap.put("controlSyntax", controlSyntax);}else{ControlSyntax controlSyntax = controSyntaxOperService.getControlSyntax(id);modelMap.put("controlSyntax", controlSyntax);}return super.wrapPage("controlSyntaxOperPage");}//新增@RequestMapping(value="zpage/controlSyntaxOper")public Map<String, Object> controlSyntaxOper(ControlSyntaxForm form){JDevActionResult result;try {String msg = controSyntaxOperService.operControlSyntax(form.getControlSyntax());if(StringUtils.isEmpty(msg)){result=super.createResultOfSuccess();}else {result=super.createResultOfFaild();result.buildMsgOfCustom(msg);}} catch (Exception e) {result=super.createResultOfFaild();result.buildMsgOfCustom("操作失败");MyWebContextHolder.recordRunException(this,e, "数据新增异常，新增失败");}return result;}//删除@RequestMapping(value="zpage/controlSyntaxDelete")public Map<String, Object> controlSyntaxDelete(ControlSyntaxForm form,ModelMap modelMap){JDevActionResult result;try {controSyntaxOperService.deleteControlSyntax(form.getId());result=super.createResultOfSuccess();}catch(DataIntegrityViolationException ex) {//数据完整性异常result=super.createResultOfFaild();result.buildMsgOfCustom("数据删除异常，违约数据信息完整性，删除失败");MyWebContextHolder.recordRunException(this,ex, "数据删除异常，违反数据信息完整性，删除失败");}catch (Exception e) {result=super.createResultOfFaild();result.buildMsgOfCustom("操作失败");MyWebContextHolder.recordRunException(this,e, "数据删除异常，删除失败");}return result;}}

然后是form代码：

public class ControlSyntaxForm extends JDevPageForm{private static final long serialVersionUID = 1L;//语法表字段private String id;private ControlSyntax controlSyntax;//set--get方法public String getId() {return id;}public void setId(String id) {this.id = id;}public ControlSyntax getControlSyntax() {return controlSyntax;}public void setControlSyntax(ControlSyntax controlSyntax) {this.controlSyntax = controlSyntax;}}

最后是两个jsp页面，下边第一个是列表页面，第二个是新增编辑页面：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ include file="/common/inc.jsp" %><page:header title="语法" ><script>function operControlSyntax(id){var w=$(window.parent).width()*0.55;var h=$(window.parent).height()*0.65;    var detailOP = new ShowDetailOp();detailOP.url="${base}/zpage/controlSyntaxOperPage.do?id="+id;detailOP.width=w;detailOP.height=h;detailOP.callback=function(data){formSearch();};detailOP.execute();}function deleteControlSyntax(id){var delOp = new DeleteOp();delOp.url='${base}/zpage/controlSyntaxDelete.do?id='+id;delOp.message='您确认要删除该笔记录吗？\n\n删除后将无法恢复。';delOp.callback=function(data){if(data.flag){parent.Dialog.alert(data.msg,function(){    formSearch();});    }else{    parent.Dialog.alert(data.msg);    }};delOp.execute();}function formSearch(){ $("#formList").submit(); }</script></page:header><div class="row"><form id="formList" name="formList" method="post" action="${base}/zpage/controlSyntaxList.do">    <table width="99%" border="0" align="center">    <tr>      <td width="50" align="right">名称：</td>      <td width="80" >      <input type="text" name="controlSyntax.name" value="${controlSyntax.name }" id="name"       class="form-control" style="width: 200px"       onkeydown="if(event.keyCode==13)formSearch()" style="float:left;" />      </td>      <td align="right" >        <div style="margin-right: -1px">        <page:button value="查询" btnClass="btn-info" iconClass="icon-search" id="find" onClick="formSearch()"></page:button>            <page:button value="新增" btnClass="btn-success" iconClass="icon-plus " id="add" onClick="operControlSyntax('');"></page:button>         </div>       </td>    </tr>    </table>    </form></div><div class="space-6"></div><div class="row">  <table class="table table-striped table-bordered table-hover" mode="list">    <thead>      <tr>        <th width="5%" align="center" nowrap="nowrap">序号</th>        <th width="15%" align="center" nowrap="nowrap">名称</th>        <th width="15%" align="center" nowrap="nowrap">类型</th>        <th width="15%" align="center" nowrap="nowrap">语法</th>        <th width="15%" align="center" nowrap="nowrap">参数</th>        <th width="15%" align="center" nowrap="nowrap">排除值</th>        <th width="20%" align="center" nowrap="nowrap">操作</th>      </tr>    </thead>    <tbody>      <c:choose>        <c:when test="${empty pageInfo.dataList}">          <tr>            <td colspan="6">无结果记录</td>          </tr>        </c:when>        <c:otherwise>          <c:forEach var="row" items="${pageInfo.dataList}" varStatus="vs">            <tr>              <td nowrap="nowrap" title = "${row.id }">                ${vs.index + 1 }              </td>                            <td nowrap="nowrap" title = "${row.name }">                ${row.name }              </td>                            <td nowrap="nowrap" title = "${enumSyntaxTypeMap[row.type].name }">                ${enumSyntaxTypeMap[row.type].name }              </td>                            <td nowrap="nowrap" >              ${row.syntax }              </td>                            <td nowrap="nowrap" title = "${row.params }">                ${row.params }              </td>                             <td nowrap="nowrap" >              ${row.excludeVals }              </td>                            <td nowrap="nowrap" align="center"><button class="btn btn-xs btn-success" onclick="operControlSyntax('${row.id}');" title="修改"><i class="icon-edit bigger-120"></i></button><button class="btn btn-xs btn-danger" onclick="deleteControlSyntax('${row.id}');" title="删除"><i class="icon-trash bigger-120"></i></button>             </td>            </tr>          </c:forEach>        </c:otherwise>      </c:choose>    </tbody>  </table>  </div>  <div class="row">    <jsp:include page="/common/pageInfo.jsp"/>  </div><script>    autoStyle();</script>    <page:footer></page:footer></html>

如果你觉得我把代码一复制-粘贴帖子就写完了，那我就太LOW了，哈哈

下面的内容才刚刚开始：

作为一个有强迫症的人，不把结构弄清楚是不会罢休的。

ssh框架 struts spring hibernate / spring springMVC hibernate 是主流的java集成开发框架，详细介绍可以自行google，这里只说我自己的理解的东西。

（个人感觉，有兴趣可以自己搭建ssh框架，可以用MyEclipse搭建也可以自己纯手动下载搭建，熟悉了整个过程之后就会对框架有一个全面了解。）

--其实我还没有完整的搭过 T^T 蓝瘦，任重而道远啊。

下面分析一下，model----service-----Action-----form-----jap 的详细结构流程

基本的先介绍到这里，有了新的理解，和更深层的认识会持续更新。
