Jasper 报告多行边框底部

Question

我想为一个多行显示其内容的文本字段绘制一个虚线底部边框。

例如：

Address: 104th Street,
         - - - - - - - - - - -- - - - - - - -- - - - - -
         Beside Market Area
         - - - - - -- - - - - -- - - - - -- - - - -- - - 
         Illinois,617273
         - - - - - -- - - - - -- - - - - -- - - - -- - - 

目前，当我将边框底部设置为文本字段时，它以这种方式显示

Address: 104th Street,
         Beside Market Area
         Illinois,617273
         - - - - - -- - - - - -- - - - - -- - - - -- - - 

请帮助我了解如何为多行文本的每行设置边框底部

如果您设法在查询中的单独字段中分手，@mbmast 解决方案当然很好，但为了回答您的问题，我将向您展示您可以在 jasper 报告中做什么“疯狂的事情”。

首先我定义了一个java.util.List 变量split 你在换行符上的字符串。我没有使用String[]，因为这会破坏报告 IDE

<variable name="addressArray" class="java.util.List">
    <variableExpression><![CDATA[Arrays.asList($F{address}.split("\\n"))]]></variableExpression>
</variable>

现在我们可以添加textField 并获得我们想要显示的位置。为了避免 ArrayIndexOutOfBoundsException 使用 printWhenExpression（为了证明这一点，我在示例中放置了 4 个 textField）

结果

Answer 2

将您的地址分成单独的字段（即 address-line-1、address-line2 等，而不是 address 中的所有内容）。然后使用<printWhenExpression> 有条件地包含该行（如果它不是空白或空）。对于要包含的内容（即满足您的条件），您可以包含一个嵌套的 <staticText> 字段作为分隔线。
