内容+模板=昄Q这里是Q?br />内容+模板-->昄?rn)态html
内容用FCK来编辑，模板也同L(fng)FCK~辑Q这里用freemarker无疑是一个好的选择。这里是个最单的例子?br />首先定义一个最单的模板content.ftl
<html>
${content}
</html>
然后是把内容填充进去：(x)
 Configuration cfg = new Configuration();
 //模板存储的目?/span>
 cfg.setDirectoryForTemplateLoading(Path.getTemplateDirectory());
 //默认
 cfg.setObjectWrapper(new DefaultObjectWrapper());

out.flush();
其实是q么单！对html的管理就很容易了(jin)Q基本的FILE操作

]]>webwork保存囄到数据库http://www.aygfsteel.com/RongHao/archive/2006/06/15/53030.htmlronghaoronghaoThu, 15 Jun 2006 09:14:00 GMThttp://www.aygfsteel.com/RongHao/archive/2006/06/15/53030.htmlhttp://www.aygfsteel.com/RongHao/comments/53030.htmlhttp://www.aygfsteel.com/RongHao/archive/2006/06/15/53030.html#Feedback0http://www.aygfsteel.com/RongHao/comments/commentRss/53030.htmlhttp://www.aygfsteel.com/RongHao/services/trackbacks/53030.html

开发中遇到q么一个要求，用户USERq个PO里需要保存用L(fng)照片。一般情况下有两U处理方法：(x)一是直接保存图片到数据库；二是保存囄到服务器端，PO字段保存一个联接。考虑到用L(fng)片一般较?yu)，采用W一U方法?br />

 1 public   class  User  extends  Principal  {
  2      private   byte [] photo;    // 考虑与各U数据库兼容问题
 3      public   byte [] getPhoto()  {
  4          return  photo;
  5     }
 6
 7      public   void  setPhoto( byte [] photo)  {
  8          this .photo  =  photo;
  9     }
10     ..
 11 }
12


面里面Q直接用webwork的FileUploadInterceptor拦截

< @ww.form  enctype = " multipart/form-data "  action = " doUpdateUser "   method = " post " >
< image name = " img1 "  src = " /getUserPhoto.action?userId=${user.id} "  width = 90  height = 120  border = " 0 " ></ image >
< @ww.file label = " %{getText('user.photo')} "  name = " photo "   />
</ @ww.form >


xwork.xml里的配置

        < action name = " doUpdateUser "   class = " com.ronghao.organization.action.OrganizationAction "  method = " updateUser " >
             < interceptor - ref name = " defaultStack " >
                 < param name = " fileUpload.allowedTypes " >
                     image / x - png,image / gif,image / pjpeg
                 </ param >
             </ interceptor - ref >
             < result name = " success " >/ organization / user.ftl </ result >
         </ action >

         < action name = " getUserPhoto "   class = " com.ronghao.organization.action.OrganizationAction "  method = " getUserPhoto " >
             < result >/ organization / user.ftl </ result >
         </ action >


引用默认的拦截器栈，栈里已经包含FileUploadInterceptor拦截Q这里配|FileUploadInterceptor拦截的参敎ͼ讑֮上传的文件ؓ(f)囄

 15              int  length  =  file.available();
 16              byte [] buffer  =   new   byte [length];
 17             file.read(buffer);
 18             file.close();
 19             user.setPhoto(buffer);    // 上传的囄转换为字节数l存储到PO?/span>

 31             outPhoto.close();
 32         }
33          return  SUCCESS;
 34     }
35 }
36


q样O(jin)K?jin)，考虑一个问题，是action 必须要指定一个result Q实际这里的囄昄仅仅是要一个输出流

< image name = " img1 "  src = " /getUserPhoto.action?userId=${user.id} "  width = 90  height = 120  border = " 0 " ></ image >


而我的配|里面是

< result >/ organization / user.ftl </ result >


不知道这?x)不会(x)有什么媄(jing)响。或者这P

< result >/ organization / blank.ftl </ result >

一、最单的情况Q未使用<display:column/>标签
  <%request.setAttribute( "test", new ReportList(6) );%>
  <display:table name="test" />
  标签遍历List里的每一个对象，q将对象里的所有属性显C出来。一般用于开发的时候检查对象数据的完整性?BR> 
二、?lt;display:column/>标签的情?/STRONG>
<display:table name="test">
  <display:column property="id" title="ID" />
  <display:column property="name" />
  <display:column property="email" />
  <display:column property="status" />
  <display:column property="description" title="Comments"/>
</display:table>
   property对应List里对象的属性（用getXXX()Ҏ(gu)取得Q，title则对应表D头里的列名。定义列有两U方式：(x)
   A?lt;display:column property="email" />
      使用<display:column/>标签里的property属性来定义
   B?lt;display:column title="email">email@it.com</display:column>
      ?lt;display:column/>标签体里增加内容Q可以是帔RQ也可以用其他标{{?BR>   两种方式比较Q用property属性来定义更加快速和利于排序?BR>  
三、表格显C样式的定义
  A、在<display:table/>?lt;display:column/>标签里指定标准的html属性，?ch)?BR>  B、修Ҏ(gu)式表
<display:table name="test" class="mars">
  <display:column property="id" title="ID" class="idcol"/>
  <display:column property="name" />
  <display:column property="email" />
  <display:column property="status" class="tableCellError" />
  <display:column property="description" title="Comments"/>
</display:table>
   通过class属性来指定所要应用的样式。可以在光认样式表里（./css/screen.cssQ直接修?BR>  
四、标{֏得数据的数据?BR>  有四U范?BR>   pageScope
   requestScope (默认)  <display:table name="test2" >
   sessionScope  <display:table name="sessionScope.holder.list" > 注意Q这里要指定范围Q非默认
   applicationScope
  
五、通过增加id属性创建隐含的对象
<display:table name="test" id="testit">
    <display:column property="id" title="ID" />
    <display:column property="name" />
    <display:column title="static value">static</display:column>
    <display:column title="row number (testit_rowNum)"><%=pageContext.getAttribute("testit_rowNum")%></display:column>
    <display:column title="((ListObject)testit).getMoney()"><%=((ListObject)pageContext.getAttribute("testit")).getMoney()%></display:column>
</display:table>
   注意到在<display:table/>里增加了(jin)id属性，q时在page context里创Z(jin)一个隐含对象，指向List里的当前对象Q?BR>   可以通过(ListObject)pageContext.getAttribute("id")来捕莯个对象。同时还创徏?jin)一个id_rowNum对象Q同P?BR>   通过pageContext.getAttribute("testit_rowNum")来捕P它仅仅代表当前行的行数?BR>   有了(jin)q两个隐含对象，可以通过其他标签来访问，例如Jstl:
  <display:table id="row" name="mylist">
    <display:column title="row number" >
      <c:out value="${row_rowNum}"/>
    </display:column>
    <display:column title="name" >
      <c:out value="${row.first_name}"/>
      <c:out value="${row.last_name}"/>
    </display:column>
  </display:table>
 
六、显C部分数?/STRONG>
   昄开始五条数据：(x)通过讑֮length属?BR><display:table name="test" length="5">
  <display:column property="id" title="ID" />
  <display:column property="email" />
  <display:column property="status" />
</display:table>
   昄W三到第八条数据Q通过讑֮offset和length属?BR><display:table name="test" offset="3" length="5">
  <display:column property="id" title="ID" />
  <display:column property="email" />
  <display:column property="status" />
</display:table> 

七、对email和url地址的直接连?/STRONG>
 <display:table name="test" >
  <display:column property="id" title="ID" />
  <display:column property="email" autolink="true" />
  <display:column property="url" autolink="true" />
 </display:table>
 如果要显C的对象里包含email和url地址Q则可以在display:column里直接设定autolink="true"来直接连?BR> 
八、用装饰模式{换数据显C（写自q decorator Q?/STRONG>
  A、对整个表格应用decorator
  <display:table name="test" decorator="org.displaytag.sample.Wrapper" >
      <display:column property="id" title="ID" />
      <display:column property="email" />
      <display:column property="status" />
      <display:column property="date" />
      <display:column property="money" />
  </display:table>
    org.displaytag.sample.Wrapper卌己写的decoratorQ它要承TableDecoratorc，看看它的一个方法：(x)
        public String getMoney()
    {
        return this.moneyFormat.format(((ListObject) this.getCurrentRowObject()).getMoney());
    }
    很明显，它通过父类的getCurrentRowObject()Ҏ(gu)获得当前对象Q然后对其getMoney()Ҏ(gu)q行‘a(b)漆?BR>  B、对单独的column应用decorator
  <display:table name="test">
     <display:column property="id" title="ID" />
     <display:column property="email" />
     <display:column property="status" />
     <display:column property="date" decorator="org.displaytag.sample.LongDateWrapper" />
  </display:table>
    org.displaytag.sample.LongDateWrapper要实现ColumnDecorator接口Q它的方法：(x)
        public final String decorate(Object columnValue)
    {
        Date date = (Date) columnValue;
        return this.dateFormat.format(date);
    }
    昄Q它获得不了(jin)当前对象Q因为它实现的是接口Q，仅仅是获得该对象的columnValueQ然后‘a(b)漆?BR>   
?ji)、创建动态连?BR>   有两U方法创建动态连接：(x)
   A、在<display:column/>里通过增加href、paramId、paramName、paramScope、paramProperty属?BR>      href             基本的URL 地址
      paramId          加在URL 地址后的参数名称
      paramName        数据bean的名Uͼ一般ؓ(f)nullQ即使用当前List里的对象Q?BR>      paramScope       数据bean的范_(d)一般ؓ(f)null
      paramProperty    数据bean的属性名Uͼ用来填充URL 地址后的参数?BR><display:table name="sessionScope.details">
  <display:column property="id" title="ID" href="details.jsp" paramId="id" />
  <display:column property="email" href="details.jsp" paramId="action" paramName="testparam" paramScope="request" />
  <display:column property="status" href="details.jsp" paramId="id" paramProperty="id" />
</display:table> 
    q种Ҏ(gu)便直接，但缺Ҏ(gu)无法产生cMdetails.jsp?id=xx&action=xx的复合URL
   B、应用decorator 创徏动态连接：(x)
<display:table name="sessionScope.details" decorator="org.displaytag.sample.Wrapper" >
  <display:column property="link1" title="ID" />
  <display:column property="email" />
  <display:column property="link2" title="Actions" />
</display:table>
   org.displaytag.sample.Wrapper里的Ҏ(gu)Q?BR> public String getLink1()
 {
  ListObject lObject= (ListObject)getCurrentRowObject();
  int lIndex= getListIndex();
  return "<a href=\"details.jsp?index=" + lIndex + "\">" + lObject.getId() + "</a>";
 }


 public String getLink2()
 {
  ListObject lObject= (ListObject)getCurrentRowObject();
  int lId= lObject.getId();

  return "<a href=\"details.jsp?id=" + lId
   + "&action=view\">View</a> | "
   + "<a href=\"details.jsp?id=" + lId
   + "&action=edit\">Edit</a> | "
   + "<a href=\"details.jsp?id=" + lId
   + "&action=delete\">Delete</a>";
 }

十、分?BR>   实现分页非常的简单，增加一个pagesize属性指定一ơ想昄的行数即?BR><display:table name="sessionScope.test" pagesize="10">
 <display:column property="id" title="ID" />
 <display:column property="name" />
 <display:column property="email" />
 <display:column property="status" />
</display:table>

十一、排?BR>   排序实现也是很简单，在需要排序的column里增加sortable="true"属性，headerClass="sortable"仅仅?BR>   指定昄的样式。column里的属性对象要实现Comparable接口Q如果没有的话可以应用decorator
   defaultsort="1"              默认W一个column排序
   defaultorder="descending"    默认递减排序
<display:table name="sessionScope.stest" defaultsort="1" defaultorder="descending">
  <display:column property="id" title="ID" sortable="true" headerClass="sortable" />
  <display:column property="name" sortable="true" headerClass="sortable"/>
  <display:column property="email" />
  <display:column property="status" sortable="true" headerClass="sortable"/>
</display:table>
  注意的是Q当同时存在分页时排序仅仅针对的是当前页面，而不是整个List都进行排?BR> 
十二、column 分组
   分组只是需要在column里增加group属?BR><display:table name="test" class="simple">
  <display:column property="city" title="CITY" group="1"/>
  <display:column property="project" title="PROJECT" group="2"/>
  <display:column property="amount" title="HOURS"/>
  <display:column property="task" title="TASK"/>
</display:table>

十三、导出数据到其他格式Q页面溢出filter??Q?/STRONG>
   ?lt;display:table/>里设定export="true"
   ?lt;display:column/>里设定media="csv excel xml pdf" 军_该字D在导出到其他格式时被包不包含，不设定则都包?BR>   <display:setProperty name="export.csv" value="false" />
   军_该种格式能不能在面中导?BR><display:table name="test" export="true" id="currentRowObject">
  <display:column property="id" title="ID"/>
  <display:column property="email" />
  <display:column property="status" />
  <display:column property="longDescription" media="csv excel xml pdf" title="Not On HTML"/>
  <display:column media="csv excel" title="URL" property="url"/>
  <display:setProperty name="export.pdf" value="true" />
  <display:setProperty name="export.csv" value="false" />
</display:table>

十四、配|属性，覆盖默认
  两种Ҏ(gu)Q?BR>  A、在E序classpath下新建displaytag.properties文g
  B、对于单个表|应用<display:setProperty>标签
  具体可配|的属性：(x)http://displaytag.sourceforge.net/configuration.html
 
十五、一个完整的例子
<display:table name="test" export="true" sort="list" pagesize="8">
  <display:column property="city" title="CITY" group="1" sortable="true"    headerClass="sortable"/>
  <display:column property="project" title="PROJECT" group="2" sortable="true" headerClass="sortable"/>
  <display:column property="amount" title="HOURS"/>
  <display:column property="task" title="TASK"/>
</display:table>
   sort="list" Ҏ(gu)个listq行排序
   导出数据到其他格式时Qgroup无效
