java - 从 Web 应用程序以 PDF 格式部署 jasperreport 时字体不起作用

Question

在我的网络应用程序中部署报告时，我遇到了一些字体问题。我希望在结果 pdf 中使用的字体是 Arial、Calibri 和 Century Gothic。

我遵循了指示的所有步骤here但无法让它工作。

这是我做的:

我修改了 jasperreports_extension.properties 的内容，如下所示:

net.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.dejavu=net/sf/jasperreports/fonts/fonts.xml
net.sf.jasperreports.extension.simple.font.families.arial=net/sf/jasperreports/fonts/fonts.xml
net.sf.jasperreports.extension.simple.font.families.calibri=net/sf/jasperreports/fonts/fonts.xml
net.sf.jasperreports.extension.simple.font.families.centurygothic=net/sf/jasperreports/fonts/fonts.xml

然后在 net\sf\jasperreports\fonts 我将包含四种样式(普通、粗体、斜体 和粗斜体) 用于前面提到的每种字体。

此外，修改了net/sf/jasperreports/fonts 中的fonts.xml，现在看起来像这样:

<?xml version="1.0" encoding="UTF-8"?>

请注意，我刚刚添加了最后三种字体。

之后，我准备了 jar 文件并将其强制放入我的应用程序类路径中。到目前为止，我刚刚得到了使用普通 Sanserif 字体导出的报告...

我不知道我做错了什么，有什么想法吗？

谢谢!

快速说明:我使用的是 Jaspersoft Studio 社区版 (6.3.0)，我的应用程序部署在 JBoss 服务器中。

我终于发现我的案例发生了什么，现在它正在工作。

当我在 Jaspersoft Studio Windows->Preferences->Fonts 中引入字体(.ttf 扩展名)时，我为 PDF 编码选择组合选择了错误的值。我首先选择了 CP1252(西欧 ANSI aka WinAnsi)，如果您想以 PDF 格式导出报告，这是错误的，然后我选择了Identity-H(Unicode with horizo​​ntal写作) 而不是它工作正常。

然而，我仍然不明白的是:如果在我的报告中我只使用 Calibri 和 Century Gothic 字体，为什么当我去查看我的 PDF 中使用的字体时(文件-> Properties->Fonts) 我在使用的字体列表中也看到了 Helvetica？
