Question

我遵循了this wiki article中的示例：

示例1，在jasperreports.properties文件中指定的值：

[CDATA[new String (net.sf.jasperreports.engine.util.JRProperties.getProperty("net.sf.jasperreports.band.split.type"))]]

所以我定义了变量：

<variable name="CrucialProperty" class="java.lang.String" resetType="Report" calculation="Nothing">
        <initialValueExpression><![CDATA[new String (net.sf.jasperreports.engine.util.JRProperties.getProperty("net.sf.jasperreports.extension.simple.font.families.dejavu"))]]></initialValueExpression>
        <variableExpression><![CDATA[new String (net.sf.jasperreports.engine.util.JRProperties.getProperty("net.sf.jasperreports.extension.simple.font.families.dejavu"))]]></variableExpression>
</variable>

但是，当尝试发布此类jrxml时，出现此错误：

我甚至尝试在jrxml文件的开头导入utils：

<import value="net.sf.jasperreports.engine.util.*" />

但未进行任何更改，无法发布jrxml。我究竟做错了什么？

Answer 1

如果我没记错的话，net.sf.jasperreports.engine.util.JRProperties类已被弃用很长时间，并且在两年前的6.2.2版本中被删除。

相反，请尝试：

net.sf.jasperreports.engine.JRPropertiesUtil.getInstance(
  $P{JASPER_REPORTS_CONTEXT}).getProperty(
    "net.sf.jasperreports.band.split.type")

无法从jrxml文件获取JasperReports属性
