渲染PDF不适用于prod环境

Question

我有一个非常奇怪的问题,渲染PDF到处工作,但不是生产.开发人员和测试环境正常运行,但prod无法处理它.现在唯一的变化是:比上一次战争更高的Grails版本(2.1.0- > 2.3.8[但这个变化已经引入测试环境〜2个月前,所有问题都解决了]),几乎没有升级过的插件,特别是

compile ":rendering:0.4.3"

变成

compile ":rendering:1.0.0"

Stacktrace我开始刺激:

我ReportController生成pdf的方法(这里没有发生任何事情,是的,pdfShow文件以下划线开头):

    def generatePdf = {
    if (!params.id) {
        throw new IllegalArgumentException("PDF Generation: an instance identifier has not been passed.")
    }
    def reportInstance = Report.findById(params.id)
    renderPdf(template: "pdfShow", model: [reportInstance: reportInstance], filename: reportInstance?.reportFilename + '.pdf')
}

我已经做了很多研究,并发现可能是pdf模板使用的.css文件中声明的字体问题.

嗯,这是.css:

@font-face {
    src: url("../fonts/DejaVuSansCondensed.ttf");
    -fs-pdf-font-embed: embed;
    -fs-pdf-font-encoding: Identity-H;
}

@font-face {
    src: url(../fonts/DejaVuSansCondensed-Bold.ttf);
    -fs-pdf-font-embed: embed;
    -fs-pdf-font-encoding: Identity-H;
}

body {
    font-family: "DejaVu Sans Condensed", Arial, sans-serif;
}

在测试和产品上都有字体.并没有改变他们的位置.

我已经尝试将rendering插件降级回来0.4.3,但它没有用,抱怨没有可用的类:

plugins\rendering-0.4.3\grails-app\services\grails\plugin\rendering\document\XhtmlDocumentService.groovy: 20: unable to resolve class org.xhtmlrenderer.resource.XMLResource
(...)\plugin\rendering\pdf\PdfRenderingService.groovy: 25: unable to resolve class com.lowagie.text.pdf.BaseFont
(...)\plugin\rendering\pdf\PdfRenderingService.groovy: 19: unable to resolve class org.xhtmlrenderer.pdf.ITextRenderer
...and few others etc.

设置在 BuildConfig.groovy

legacyResolve true

里面grails.project.dependency.resolution { ...也没用.

你知道什么是错的吗？

解决问题的方法是在以下内容中添加一行Config.groovy：

environments {
    production {
        (...)
        grails.resources.processing.enabled = false

我们在test和development环境中有这条线，但之前，在 Grails 2.1.0 中它仍然可以工作。
