Spring 启动抱怨 OptaPlanner
Spring Boot complaining about OptaPlanner
我有一个小型 OptaPlanner 应用程序，无需 Spring 启动即可正常运行。我基本上改变了云平衡 opta 应用程序的用途。我还包含了所有 Spring 引导依赖项。 POM 父级是 spring-boot-starter-parent。我有 optaplanner-spring-boot-starter 作为依赖。
使用此设置，我仍然可以 运行 opta 应用程序而不会出现问题。然后我在项目中添加了一个 Spring Boot app。应用如下：
package org.optaplanner.examples;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
不幸的是，当我 运行 这个 spring 启动应用程序时，我得到以下错误异常：
Maybe your @ConstraintProvider annotated class is not in a subpackage of your @SpringBootApplication annotated class's package.
Maybe move your constraint provider class to your application class's (sub)package.
我有一个 constraints.drl 文件，其中包含所有流口水规则。它位于 src/main/resources/org/optaplanner/examples 下；据我所见，它与 spring 启动应用程序位于同一个包中。即使在 constraints.drl 文件中，我也有以下声明：
package org.optaplanner.examples;
dialect "java"
所以我有点困惑。下面是完整的 exception.I 必须注意我有云平衡示例附带的求解器：cloudBalancingSolverConfig.xml.
有什么建议吗？

在错误消息中向右滚动。 spring 引导日志隐藏了错误消息的第一部分：
No classes found that implement EasyScoreCalculator, ConstraintProvider or IncrementalScoreCalculator, nor a constraints.drl resource.
Maybe your @ConstraintProvider annotated class is not in a subpackage of your @SpringBootApplication annotated class's package.
Maybe move your constraint provider class to your application class's (sub)package.
这意味着它没有看到 constraints.drl。
如果你有 solverConfig.xml，它可能也看不到。
修复：将您的 fooSolverConfig.xml 移至 src/main/resources/solverConfig.xml 或使用 application.properties 说明它的位置。
该求解器配置说明了您的 scoreRules.drl 所在的位置。
您也可以删除 <scoreDrl> 行，然后将 fooScoreRules.drl 设为 src/main/resources/constraints.drl
显然错误消息有点（也？）偏向于 ConstraintStreams :)
