Question

我的grails渲染插件有问题。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')

虽然它不想要我，但在renderPdf调用上抛出了NPE：

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

完整的堆栈跟踪位于此Pastebin Paste

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

拉出插件

有多个条目指向org.springframework.security.web。

您是否检查了未经授权的插件是否按预期工作？如果是这样，则问题出在安全配置上。
