jasper-reports - Jasper 报告 + 表格组件 + 数据集在 PDF 中没有输出

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。

请告诉我在这里做错了什么？

数据源：JavaBeans (POJO)

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，但你没有什么可以填写的。

在您的基本报告中，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，我通常使用一些非常简单的东西，例如

select sysdate from dual

然后在您的数据集中，您还需要一个查询来提取您的数据

select orgDskUsage,orgID,orgMsgSize,OrgName from dual

当然，您需要将 from 更改为您的表格

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 ]]>
