使用 Optaplanner VRP 示例和 optaplanner-spring-boot-starter
Using Optaplanner VRP example with optaplanner-spring-boot-starter
我正在尝试创建一个应用程序来解决 VRP 问题，但当我使用来自 VRP 示例代码的域 classes 时收到此错误消息。在版本 8.19.0.Final
“规划实体是未配置为规划实体class（[class com.test.vrp.domain.Customer, class com.test.vrp.domain.timewindowed.TimeWindowedCustomer]).
If that class (Vehicle) (or superclass thereof) is not a @PlanningEntity annotated class, maybe your @PlanningSolution annotated class has an incorrect @PlanningEntityCollectionProperty or @PlanningEntityProperty annotated member.
Otherwise, if you're not using the Quarkus extension or Spring Boot starter, maybe that entity class (Vehicle) is missing from your solver configuration."
The Vehicle class is not configured as planning entity class, although it implements "Standstill" which is annotated as a Planning Entity.
我所做的任何更改（例如将车辆注释为规划实体）只会产生其他错误。

看起来问题是代码从 optaplanner-examples 迁移到具有不同包结构的新项目的结果。
这是消息的重要部分：
A planning entity is an instance of a class (class com.test.vrp.domain.planner.Vehicle)
that is not configured as a planning entity class ([
class com.test.vrp.domain.planner.Customer,
class com.test.vrp.domain.planner.timewindowed.TimeWindowedCustomer
]).
我怀疑您项目中的 solverConfig.xml 被 忽略 并且这不一定是坏事或问题的原因。我这么认为的原因是您在评论中共享的 FQCN 与异常消息中的完全不同。我想如果您删除 solverConfig.xml 异常将保持不变。
optaplanner-spring-boot-starter 工件包含一个扩展，它将自动发现您的 @PlanningSolution 和您的 @PlanningEntity 注释 classes，前提是它们位于 sub-package你的 @SpingBootApplication。从异常消息中，我们可以看到 Customer 和 TimeWindowedCustomer 已被发现（尽管您的 solverConfig.xml 中有内容）但缺少 com.test.vrp.domain.Standstill。 尝试解决这个问题:
- 确保
com.test.vrp.domain.Vehicle 扩展 com.test.vrp.domain.Standstill。
- 确保
com.test.vrp.domain.Standstill 在您的项目的 com.test.vrp.domain 包中。
- 检查
com.test.vrp.domain.Standstill 是否有 @PlanningEntity 注释。
还要检查您的 @SpringBootApplication 注释 class 是否在 com.test.vrp 或 com.test.vrp.domain 包中。

看起来问题是代码从 optaplanner-examples 迁移到具有不同包结构的新项目的结果。
这是消息的重要部分：
A planning entity is an instance of a class (class com.test.vrp.domain.planner.Vehicle)
that is not configured as a planning entity class ([
class com.test.vrp.domain.planner.Customer,
class com.test.vrp.domain.planner.timewindowed.TimeWindowedCustomer
]).
我怀疑您项目中的 solverConfig.xml 被 忽略 并且这不一定是坏事或问题的原因。我这么认为的原因是您在评论中共享的 FQCN 与异常消息中的完全不同。我想如果您删除 solverConfig.xml 异常将保持不变。
optaplanner-spring-boot-starter 工件包含一个扩展，它将自动发现您的 @PlanningSolution 和您的 @PlanningEntity 注释 classes，前提是它们位于 sub-package你的 @SpingBootApplication。从异常消息中，我们可以看到 Customer 和 TimeWindowedCustomer 已被发现（尽管您的 solverConfig.xml 中有内容）但缺少 com.test.vrp.domain.Standstill。 尝试解决这个问题:
- 确保
com.test.vrp.domain.Vehicle扩展com.test.vrp.domain.Standstill。 - 确保
com.test.vrp.domain.Standstill在您的项目的com.test.vrp.domain包中。 - 检查
com.test.vrp.domain.Standstill是否有@PlanningEntity注释。
还要检查您的 @SpringBootApplication 注释 class 是否在 com.test.vrp 或 com.test.vrp.domain 包中。
