Question

我正在尝试使用Table组件生成 JR 报告。但是生成的PDF文件中没有显示任何数据。也没有错误。

请告诉我这里做错了什么？

数据源：JavaBeans（POJO）

JRXML文件

Answer 1

您的问题是您没有任何查询来提取任何数据。你定义了你的领域，但没有任何东西可以填补它们。

在您的基础报告中，您需要一些数据，以便您的表格显示其他明智的jasper认为报告是空白的，我通常使用非常简单的东西，如

select sysdate from dual

然后在您的数据集中，您还需要一个查询来提取数据

select orgDskUsage,orgID,orgMsgSize,OrgName from dual

当然你需要将from改为你的表

在您的代码中添加第25行

<![CDATA[select orgDskUsage,orgID,orgMsgSize,OrgName from dual]]>

和第41行

<![CDATA[select sysdate from dual ]]>

对于Jasper Report + Table Component + Dataset，PDF中没有输出
