使用 contraints.drl 和 Spring 引导的 Optaplanner 错误消息
Optaplanner error messages using contraints.drl with Spring Boot
我正在使用带有 optaplanner-spring-boot-starter 的 optaplanner 8.3.0，并且我正在使用 constraints.drl 文件。在之前的版本中，drl的报错都比较清楚，并且有行号等
在此配置中，我收到如下日志消息：
类型化表达式输入：drlxExpr = volume，patternType = class com.drift.excelsgl.domain.planning.ExpectedTankLevel，declarations = []

有没有办法检查 returns“旧”消息的 drl 文件？
只是java.lang.IllegalStateException: There is an error in a scoreDrl or scoreDrlFile.确实没有用。通常，该异常应该具有实际行号的链式异常。
没有实际的堆栈跟踪吗？如果我 运行 spring-boot-school-timetabling 无效 constraints.drl:
