OptaPlanner Xml配置和entitySubclass未配置为计划实体错误 [英] OptaPlanner Xml configuration and entitySubclass is not configured as a planning entity error

问题描述

我是OptaPlanner的新手，在配置解决方案方面有些困难.我已经正确注释了所有类，但是运行求解器时出现以下错误.

I am new to OptaPlanner and having some diffculty in configuring the solution. I have anotated all of the classes correctly but I am getting the following error when the solver runs.

A planning entity is an instance of a entitySubclass (class 
org.optaplanner.core.impl.score.director.drools.DroolsScoreDirector) that is not 
configured as a planning entity.
If that class (DroolsScoreDirector) (or superclass thereof) is not a entityClass 
([...Part]), check your Solution implementation's annotated methods.
If it is, check your solver configuration

这是我当前正在使用的xml配置.

Here is the xml configuration I am currently using.

<?xml version="1.0" encoding="UTF-8"?>
<solver>
    <solutionClass>(package name).SheetNesting</solutionClass>
    <planningEntityClass>(package name).Part</planningEntityClass>
    <scoreDirectorFactory>
        <scoreDefinitionType>HARD_SOFT</scoreDefinitionType>
        <scoreDrl>/Resources/Drools/NestingRules.drl</scoreDrl>
    </scoreDirectorFactory>
    <termination>
        <maximumSecondsSpend>500</maximumSecondsSpend>
    </termination>
    <constructionHeuristic>
        <constructionHeuristicType>FIRST_FIT_DECREASING</constructionHeuristicType>
    </constructionHeuristic>
    <localSearch>
    <unionMoveSelector>
      <changeMoveSelector>
        <valueSelector>
          <variableName>sheet</variableName>
        </valueSelector>
      </changeMoveSelector>
      <moveListFactory>
          <moveListFactoryClass>(package name).XPosMoveFactory</moveListFactoryClass>
      </moveListFactory>
      <moveListFactory>
          <moveListFactoryClass>(package name).YPosMoveFactory</moveListFactoryClass>
      </moveListFactory>
    </unionMoveSelector>
    <acceptor>
      <lateAcceptanceSize>600</lateAcceptanceSize>
    </acceptor>
    <forager>
      <acceptedCountLimit>4</acceptedCountLimit>
    </forager>
  </localSearch>
</solver>

输出显示解决方案已建立(可能会评估Phase(0)，但会引发错误.将不胜感激.

The output shows that the solution establishes (possible evaluates Phase(0) but then the error is thrown. Any help will be appreciated.

*编辑 首先，谢谢您的评论. Part类的定义如下

*EDIT Firstly thank you for your comments. The definition of the Part class is as follows

@PlanningEntity(difficultyComparatorClass = PartComparator.class)
public class Part 
{
     ....
    @PlanningVariable(valueRangeProviderRefs = {"sheetRange"})
    public Sheet getSheet()
    {
        ....
    }


    @PlanningVariable(valueRangeProviderRefs = {"xPosRange"})
    public double getXCenter()
    {
        ....
    }

    @PlanningVariable(valueRangeProviderRefs = {"yPosRange"})
    public double getYCenter()
    {
        ....
    }
}

如您所见，该类已完全注释，如前所述.这就是为什么我认为问题出在配置上的原因.

As you can see the class is fully annotated, as described. This is why I believed the issue was with the configuration.

推荐答案

该问题的错误消息有些令人误解.但是，这是准确的.该问题是由配置的一个组件引起的，对我来说，这是一个完全的监督.

The error message for the problem was a little missleading. However, it was accurate. The issue was being caused by a component of the configuration and was a complete oversight on my part.

自定义移动方法是将得分控制器传递给beforeVariableChanged(object，string)方法，而不是Part类.

The custom move methods were passing the score director through to the beforeVariableChanged(object, string) method, instead of the Part class.

谢谢您的帮助.
