grails 渲染插件在渲染 PDF 时失败

Question

我在使用grails渲染插件时遇到了问题。控制器准备数据并调用 renderPdf

def reportergebnis = Reparaturauftrag.all.findAll{
params.datumvon <= it.auftragsdatum && it.auftragsdatum <= params.datumbis && params.auftragsstatus.contains(it.auftragsstatus.id.toString())
}
renderPdf(template: 'report', model: [reportergebnis: reportergebnis], filename: 'report.pdf')

它不想要我，并在 renderPdf 调用中抛出一个 NPE：

Caused by NullPointerException: null
->> 1337 | getPublicDeclaredMethods in java.beans.Introspector

完整的堆栈跟踪在此粘贴粘贴上

关于这可能是什么的任何想法？ 我正在使用grails 3和gradle，并通过build.gradle和compile 'org.grails.plugins:rendering:2.0.3'拉动插件

有几个条目指向org.springframework.security.web。

您是否在未经授权的情况下检查过插件是否按预期工作？如果是这样，则问题出在安全配置上。
