我是JasperReports和iReport的新手。

我已经创建了一个主报告，它保存了自己的查询和我将要包含的所有子报告。没有对任何子报告的疑问。

我将向主报表添加一个子报表，并将其设置为使用数据源，该数据源是从主报表传递的参数。

我在主报表的详细部分中包含了子报告，因为它将显示数据。

当我运行主报表时，它将获取子报表，传递数据并将其添加到子报表中，但由于某种原因，它会从子报表中的数据集中删除第一行。最后，它开始显示子报表中第二行的数据。当我不包括子报表并将字段直接放入主报表的细节时，它会显示所有的行。

我已经尝试增加两个reports部分的大小/高度和宽度，但是它仍然删除子报表中的第一行。我不知道下一步该怎么做，看看问题出在哪里。

是否需要设置子报告的配置才能使其正常工作？

我终于得到了答案。

我需要的是将$P{REPORT_CONNECTION}传递给我的子报表，这意味着每个报表都可以有自己的查询。主要报告和所有分报告

步骤：

  1. 对我的主要报告进行查询
  2. 通过从调色板中拖动创建子报表。
  3. 关于子报表属性。设置使用连接表达式
  4. 关于子报表属性。使用$P{REPORT_CONNECTION}值
  5. 通过主报表打开子报表，即右键单击主报表上的子报表标记，然后单击“打开子报表”。出于某种原因，当我这样做时，它打开了相同的子报告，但是它显示了我单独打开它时所做的更改。我认为这就是变化的来源，因为在我对像这样打开的那个做了改变之后，所有这些都是100%起作用的。

谢谢你的建议

为了详细说明这个主题，我在JavaBeanCollectionDataSource中也有同样的问题。我有一个主报告，其中包括许多子报告，我希望所有的子报告都被输入主数据源。使用$P{REPORT_DATA_SOURCE}作为所有子报表中的数据源表达式，只会查看第一个子报表(还会丢失第一行，因为主报表消耗了它)。

解决方案：需要为每个子报表提供数据源的新实例

How：在填充期间，为添加每个子报告数据集的克隆实例。例如：

代码语言：javascript
复制
Map parameters = new HashMap();
parameters.put("MasterDataSourceInstance_1", beanColDataSource.cloneDataSource());
parameters.put("MasterDataSourceInstance_2", beanColDataSource.cloneDataSource());

在报告档案中：

代码语言：javascript
复制
<parameter name="MasterDataSource_1" class="net.sf.jasperreports.engine.data.JRBeanCollectionDataSource"/>
<parameter name="MasterDataSource_2" class="net.sf.jasperreports.engine.data.JRBeanCollectionDataSource"/>

现在，您可以使用数据源实例(每次只使用一次)：

代码语言：javascript
复制
<dataSourceExpression><![CDATA[$P{MasterDataSource_1}]]></dataSourceExpression>
