标签：java报表导出
在项目中一般导出报表用poi，但是如果你不想用框架就用简单的jsp也可以实现报表导出。而且实现起来还特别简单。先看一下效果截图：

具体实现：
第一：在页面的列表页面中就是普通的iterator源码如下：
<table class="list_tab">
<tr class="head">
<th>序号</th>
<th width="20px"><input type="checkbox" class="inp02" style="vertical-align: middle;" id="sall"/></th>
<th>体检编号</th>
<th>档案编号</th>
<th>姓名</th>
<th>性别</th>
<th>年龄</th>
<th>手机号码</th>
<th>阳性项目结果</th>
</tr>
<s:iterator value="listsickpeople" status="s">
<tr class="row"
onmouseover="this.className=‘overrow‘"
onmouseout="this.className=‘row‘" align="center">
<td><s:property value="#s.index+1" /></td>
<td><input type="checkbox" class="inp02" name="recordids" style="vertical-align: middle;" value="<s:property value="record_id" />"/></td>
<td><s:property value="record_id" /></td>
<td><s:property value="archive_id" /></td>
<td><s:property value="real_name" /></td>
<td align="center"><s:if test="sex==0">
<div class="sexw"></div>
</s:if> <s:elseif test="sex==1">
<div class="sexm"></div>
</s:elseif></td>
<td><s:property value="age" /></td>
<td><s:property value="contact_tel" /></td>
<td align="left"
title="<s:property value="is_yang_value" />"><s:property
value="@com.hljw.util.UtilAPI@strBeyondHidden(is_yang_value,50)" /></td>
</tr>
</s:iterator>
<s:if test="countTotal==0">
<tr class="tiprow">
<td colspan="9">没有找到符合条件的数据</td>
</tr>
</s:if>
</table> public String exportPositiveResult() {
if (qureyBean == null) {
qureyBean = new SickPeople();
}
//这是将复选框的数组转化为sql的in条件
String[] record_ids = this.getParameterValues("recordids");
String record_id = stringArray2StringIn(record_ids);
qureyBean.setRecord_id(record_id);
listsickpeople = recordService.positiveresult(qureyBean, 1, 1000000);
this.dictService.setDictName2ListData(listsickpeople, CacheGlobal.DICT_SEX);
execlFileName = UncDate.formatDateTime(new Date(), "yyyyMMddHHmmss");
return SUCCESS;
}
/**
* 将逗号隔开的数组转成In条件
*
* @param str
* @return
*/
public String stringArray2StringIn(String[] recordids) {
StringBuffer idsStr = new StringBuffer();
for (int i = 0; recordids != null && i < recordids.length; i++) {
if (i != 0) {
idsStr.append(",");
}
idsStr.append("‘").append(recordids[i]).append("‘");
}
return idsStr.toString();
}
第三：action执行后跳转的jsp。（这个特殊地方有两点：第一在头文件需要加一些语句。第二页面只需要导出报表需要的数据，没有任何js和css）源码如下：
<%@ page language="java" contentType="text/html; charset=GBK"
pageEncoding="GBK"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
String execlFileName = (String)request.getAttribute("execlFileName");
response.setHeader("Content-disposition","attachment; filename="+execlFileName+".xls");
response.setHeader("Pragma", "");
response.setHeader("Cache-Control", "");
%>

<td><s:property value="record_id" /> </td>
<td><s:property value="archive_id" /> </td>
<td><s:property value="real_name" /> </td>
<td><s:property value="sex" /> </td>
<td><s:property value="age" /> </td>
<td><s:property value="contact_tel" /> </td>
<td align="left"><s:property value="is_yang_value" /> </td>
</tr>
</s:iterator>
</table>
