Jasperreport jrxml 对子报表传参数

Jasperreport jrxml 对子报表传参数

过程：

1. 子报表需要绝对路径

2. 对子报表传递路径参数

3. 网上很难找到jrxml的传参例子，官网也找不到，都是在图形界面设计的例子

4. 从蛛丝马迹猜到怎么写

http://bbs.csdn.net/topics/300193115/ 在程序里怎么给交叉报表

5. 结果总是报错：发现了以元素 'subreportParameter' 开头的无效内容。以为是XML标签写错

6. 又继续找到一个例子，并看回错误日志

http://www.iteye.com/problems/80489 Jasper sub report的记录数问题

7. 最后，才，发，现，这，个，坑，爹，问题

原来，参数标签必须要在<reportElement>之后才行，坑爹啊，居然还有顺序的。。。。

<subreport>
<reportElement uuid="5c982691-19bb-4b82-9353-cec4b96b4d2e" positionType="Float" x="21" y="70" width="720" height="20"/>
<subreportParameter name="SOURCE_DIR">
<subreportParameterExpression><![CDATA[$P{SOURCE_DIR}]]></subreportParameterExpression>
</subreportParameter>
<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{gqkList})]]></dataSourceExpression>
<subreportExpression><![CDATA[$P{SOURCE_DIR} + "cjtongjilist_3.jasper"]]></subreportExpression>
</subreport>
