以下是一些演示问题的屏幕截图:首先,这是没有列表元素的设计:

这是该报告的结果(注意有两页):

现在如果我添加列表元素,设计如下:

这是摘要带的 jrxml:

最后是该报告的结果。

enter image description here

请注意, float 的“静态文本”标签已适当向下移动,但还不足以向报告添加额外的页面。但是,无论如何您都会看到报告现在有 3 页。

唯一改变的是添加了列表元素。我怎样才能让它不添加额外的页面?或者我对列表有什么不了解?我可能还可以将数据传递到子报表中,以便数据显示在子报表的详细信息区域中,但如果可以的话,我更愿意使用列表,因为它对我来说似乎更简单。我使用的是 6.6.0 版。谢谢!

这是请求的完整 jrxml(删除了 uuid 以节省字符):

最佳答案

我以前遇到过这个问题,我所做的修复是。

  1. 检查详细信息区域的大小并确保生成的值列表可以全部放入同一页面。缩小细节带的大小以查看差异。
  2. 另一个是隐藏未使用或空的带。例如,尝试将 Summary 带的 Print When Expression 设置为 Boolean.FALSE 以隐藏它。
  3. 您还可以转到报告属性 > 勾选忽略分页属性

关于jasper-reports - Jasper 报告列表元素产生额外的页面,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/50914003/
