多行的 Jasper 报告边框底部

Question

我想为以多行显示其内容的文本字段绘制虚线底部边框。

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
         - - - - - -- - - - - -- - - - - -- - - - -- - -

请帮我看看如何为多行文本的每行设置边框底部

Answer 1

将您的地址分成不同的字段（即 address-line-1、address-line2 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（如果它不是空白或空）。对于要包含的那些（即满足您的条件），您可以为分隔线包含一个嵌套的 <staticText> 字段。

Answer 2

如果您在查询中设法在单独的字段中分解，当然 @mbmast 解决方案很好，但为了回答您的问题，我将向您展示 "crazy stuff" 您可以在 jasper 报告中做什么。

首先，我定义了一个 java.util.List 变量，split 你在字符串中换行。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并且只得到我们想要显示的位置。为了避免 ArrayIndexOutOfBoundsException 使用 printWhenExpression（为了证明这一点，我在示例中放了 4 textField）
