Jasper报告多条线的边界底部

标签： jasper-reports

我想为文本字段绘制一个虚线底部边框，以多行显示其内容。

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，它将以这种方式显示

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

请帮我解决如何为多行文字设置每行的边框底部

如果你设法在查询的单独字段中分手肯定@mbmast解决方案是好的，但是为了回答你的问题，我将向你展示你可以在jasper报告中做什么“疯狂的东西”。

首先，我定义一个java.util.List变量，在你的换行符上split为String。我没有使用String[]，因为这打破了报告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并获取我们想要显示的内容的位置。为了避免ArrayIndexOutOfBoundsException使用printWhenExpression（为了证明这一点，我在示例中添加了4个textField）

答案 1 :(得分：2)

将您的地址分成不同的字段（例如地址行1 ，地址行2 等，而不是地址中的所有内容）。然后使用<printWhenExpression>有条件地包含该行（如果它不是空行或null）。对于要包含的那些（即满足您的条件），您可以为分隔线包含嵌套的<staticText>字段。
