实现用于基准测试的 SolutionIO 接口

Question

我正在尝试在我的项目中实施基准配置，但无论我做什么，我似乎都遇到了某种错误。在阅读了几次文档后，我发现我需要实现一个 SolutionIO 接口来读取输入并将其转化为解决方案。

这是我没有解算器的配置：

<benchmarkDirectory>local/data/nurserostering/folder</benchmarkDirectory>
<inheritedSolverBenchmark>
    <problemBenchmarks>
        ----> <problemIOClass>org.optaplanner.examples.nurserostering.persistence.CustomBenchmarkIO</problemIOClass> <-----
        <inputSolutionFile>data/nurserostering/import/importTest/Input0.xml</inputSolutionFile>
    </problemBenchmarks>

我得到的错误是在 <problemIOClass> 标记处（见 post 的末尾）。

这是我的 CustomBenchmarkIO（自定义解决方案 IO）：

package org.optaplanner.examples.nurserostering.persistence;
import java.io.File;
import org.optaplanner.core.api.domain.solution.Solution;

public interface CustomProblemIOInterface {

String getFileExtension();

Solution read(File inputSolutionFile);

void write(Solution solution, File outputSolutionFile);
}

这里我有一个实现该接口的 class：

package org.optaplanner.examples.nurserostering.persistence;
import java.io.File;
import org.optaplanner.core.api.domain.solution.Solution;
import    org.optaplanner.persistence.common.api.domain.solution.SolutionFileIO;

public class CustomBenchmarkIOClass implements CustomProblemIOInterface{

public String getInputFileExtension() {
    return null;
}

public String getOutputFileExtension() {
    // TODO Auto-generated method stub
    return null;
}

public Solution read(File inputSolutionFile) {
    return null;
}

public void write(Object solution, File outputSolutionFile) {

}

}

我已经尝试使用 class 和界面，但我仍然遇到同样的错误。

这是完整的错误日志：

我post回答这个问题是因为我不知道我还没有尝试过什么，因为我不知道实施基准测试的所有可能方法。

您需要从 optaplanner 本身实现一个接口，称为 SolutionFileIO：您不需要定义自己的接口。这些天它在罐子里 optaplanner-persistence-common。
