我有一个非常奇怪的问题,渲染PDF无处不在,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
[但是这个变化已经被引入测试环境〜2个月前所有的问题都是然后解决了几个升级的插件,特别是
compile ":rendering:0.4.3"
更改为
compile ":rendering:1.0.0"
Stacktrace我开始生产:

我生成pdf的ReportController
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,发现可能是pdf模板使用的.css文件中声明的字体存在问题。
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;
}
字体在那里,无论是测试还是产品。并没有改变他们的位置。
我尝试将rendering
插件降级回0.4.3
,但它没有用,抱怨没有可用的课程:
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.
在BuildConfig.groovy
legacyResolve true
内grails.project.dependency.resolution { ...
也无效。
你知道可能出现什么问题吗?
答案 0 :(得分:0)
解决问题的方法是在Config.groovy
添加一行:
environments {
production {
(...)
grails.resources.processing.enabled = false
我们在test
和development
环境中使用了这一行,但之前使用Grails 2.1.0它仍然有用。
