Optaplanner错误消息使用contraints.drlSpring Boot

Question

我正在使用optaplanner 8.3。0和optaplanner spring启动程序，我使用的是约束。drl文件。在以前的版本中，drl错误相当明显，并且有行号等。

在此配置中，我将收到如下日志消息：

类型化表达式输入：drlxexpr=卷，模式类型=类com.drift.excelsgl.domain.planning.预期坦克级别，声明=[]

...

有没有办法检查返回“旧”消息的drl文件？

Answer 1

只是java。lang.IllegalStateException:scoreDrl或scoreDrlFile中存在错误 确实没有用。通常情况下，应该有一个链接异常，该异常带有实际的行号。

没有实际的堆栈跟踪吗？如果我使用无效的约束运行spring boot school时间表，我会得到以下结果。drl：

这清楚地表明行号行1:0不匹配的输入'go'。我们如何重现你的案例？
