Optaplanner

Question

我是 OptaPlanner 的新手，我专注于 基准测试。我开始使用 Eclipse 中的基准测试。我遵循了文档 (http://docs.jboss.org/optaplanner/release/6.4.0.Final/optaplanner-docs/html_single/index.html#buildAndRunAPlannerBenchmark)，但是在尝试运行时，我得到了这个 error:

Exception in thread "main" java.lang.IllegalArgumentException: The benchmarkConfigResource (prova/src/prova/nurseRosteringBenchmarkConfig.xml) does not exist as a classpath resource in the classLoader (sun.misc.Launcher$AppClassLoader@73d16e93).
    at org.optaplanner.benchmark.impl.XStreamXmlPlannerBenchmarkFactory.configure(XStreamXmlPlannerBenchmarkFactory.java:100)
    at org.optaplanner.benchmark.api.PlannerBenchmarkFactory.createFromXmlResource(PlannerBenchmarkFactory.java:45)
    at prova.ClasseJava.main(ClasseJava.java:10)

也许我在 Java 中做错了什么（我需要复查），所以这是我的代码:

package prova;

import org.optaplanner.benchmark.api.PlannerBenchmark;
import org.optaplanner.benchmark.api.PlannerBenchmarkFactory;

public class ClasseJava {
    public static void main(String[] args) {
        System.out.println("Ok - Before");
        PlannerBenchmarkFactory plannerBenchmarkFactory = PlannerBenchmarkFactory.createFromXmlResource(
                "prova/src/prova/nurseRosteringBenchmarkConfig.xml");
        System.out.println("Ok - After");
        PlannerBenchmark plannerBenchmark = plannerBenchmarkFactory.buildPlannerBenchmark();
        plannerBenchmark.benchmark();
    }   
}

Info: 我已将文件 nurseRosteringBenchmarkConfig.xml 放在同一个 ClasseJava 的包中(prova).

感谢您的一点帮助。

类路径资源就像包名和完整的类名。因为你的包名是 "prova"，你的类路径资源是 "prova/nurseRosteringBenchmarkConfig.xml".

    PlannerBenchmarkFactory plannerBenchmarkFactory = PlannerBenchmarkFactory.createFromXmlResource(
            "prova/nurseRosteringBenchmarkConfig.xml");

Optaplanner - benchmarkConfigResource 在类加载器中不作为类路径资源存在

Optaplanner - The benchmarkConfigResource does not exist as a classpath resource in the classLoader
