OptaPlanner：java.lang.IllegalArgumentException(OptaPlanner: java.lang.IllegalArgumentException)

 目前我正在OptaPlanner中实施我的第二个项目。 我正在检索以下错误： 
 
    Exception in thread "main" java.lang.IllegalArgumentException:
    A planning entity is an instance of a entitySubclass (class com.company.Assignment)
    that is not configured as a planning entity.
    If that class (Assignment) (or superclass thereof) is not a entityClass 
    ([class com.company.Car]), check your Solution implementation's annotated methods.
    If it is, check your solver configuration.
 
 我的SolverConfig.xml是这样的： 
 
<?xml version="1.0" encoding="UTF-8"?>
<solver>
<solutionClass>com.company.Planning</solutionClass>
<entityClass>com.company.Car</entityClass>
<scoreDirectorFactory>
    <scoreDefinitionType>HARD_SOFT</scoreDefinitionType>
    <easyScoreCalculatorClass>com.company.PlanningEasyScoreCalculator</easyScoreCalculatorClass>
    <initializingScoreTrend>ONLY_DOWN</initializingScoreTrend>
</scoreDirectorFactory>

    <constructionHeuristicType>FIRST_FIT</constructionHeuristicType>

    </forager>
</localSearch>
</solver>
 
 “Car”类用“@PlanningEntity”注解。 “规划”类用“@PlanningSolution”注解。 塔“分配”类是我的问题的事实。 该解决方案的“@PlanningEntityCollectionProperty”位于运行“Car”列表的getter上。 
 
 “Main”类看起来像这样： 
 
public class Main {
public static final String SOLVER_CONFIG_XML = "com/company/PlanningSolverConfig.xml";
public static ScoreDirector scoreDirector;
public static void main(String[] args) {
    // Read data from XLS file and initialize the problem
    ReadDataFromXls Reader = new ReadDataFromXls();
    Planning planningSituation = new Planning(Reader.ReadAssignments(),Reader.ReadCars());
    // Build the solver
    Solver solver = SolverFactory.createFromXmlResource(SOLVER_CONFIG_XML).buildSolver();
    // Solve the problem and get the best solution
    solver.solve(planningSituation);
    Planning solvedPlanning = (Planning) solver.getBestSolution();
    // Display the result
    System.out.println("TODO");
}
}
 
 错误消息与6.3.0.CR1基本相同+有关SLF4J的错误 
 
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

If it is, check your solver configuration.
 
 编辑：我在OptaPlanner的第一个项目是“一对多”的问题（一个项目有一个开发人员，一个开发人员可以有多个项目）。 这个项目是一个“一对一”的问题（一辆车需要驾驶到一个任务，一个任务由一辆汽车重新开始）。 
 
 编辑：我改变了计划问题的模型。 现在，“作业”课程是我的“计划实体”，而“汽车”课程则是“计划事实”。 错误信息仍然是一样的，除了“车”和“分配”切换位置的事实:) 

currently i am implementing my second project in OptaPlanner. I am retrieving the following error:
 
    Exception in thread "main" java.lang.IllegalArgumentException:
    A planning entity is an instance of a entitySubclass (class com.company.Assignment)
    that is not configured as a planning entity.

My SolverConfig.xml is this:

The "Car" class is annotated with "@PlanningEntity". The "Planning" class is annotated with "@PlanningSolution". Tha "Assignment" class is my problem fact. The solution's "@PlanningEntityCollectionProperty" is on a getter that runs a list of "Car".
 
The "Main" class looks like this:
 
public class Main {
public static final String SOLVER_CONFIG_XML = "com/company/PlanningSolverConfig.xml";
public static ScoreDirector scoreDirector;
public static void main(String[] args) {
    // Read data from XLS file and initialize the problem
    ReadDataFromXls Reader = new ReadDataFromXls();
    Planning planningSituation = new Planning(Reader.ReadAssignments(),Reader.ReadCars());
    // Build the solver
    Solver solver = SolverFactory.createFromXmlResource(SOLVER_CONFIG_XML).buildSolver();
    // Solve the problem and get the best solution
    solver.solve(planningSituation);
    Planning solvedPlanning = (Planning) solver.getBestSolution();
    // Display the result
    System.out.println("TODO");
}
}
 
Error message with 6.3.0.CR1 is basically the same + an error concerning SLF4J
 
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

If it is, check your solver configuration.
 
EDIT: My first project in OptaPlanner was a "One to Many" problem (a project has a developer, a developer can have multiple projects). This project is a "One to One" problem (a car is needed to drive to an assignment, an assignment is reched by a car).
 
EDIT: I changed the model of my planning problem. Now the class "Assignment" is my "planning entity" and the class "Car" is the "planning fact". The error message ist still the same, besides the fact that "Car" and "Assignment" switched places :)
