Question

我有一个使用Optaplanner生成计划的应用程序。当我编写一个集成测试并使用mvn Integration-test从终端的命令行调用该测试时，optaplanner会引发异常。异常是由于“在org.optaplanner.core.config.domain.ScanAnnotatedClassesConfig.buildSolutionDescriptor（ScanAnnotatedClassesConfig.java:84）”引起的“ java.lang.IllegalStateException：zip文件已关闭”。

生产代码有效，我的直觉是无法使用此路径找到求解器配置资源：

solverFactoryBase = SolverFactory
                .createFromXmlResource("solver/solverConfig-minDistanceTimeToProcess.xml");

这是异常堆栈跟踪：

请勿将createFromXmlResource()与createFromXmlFile()混淆。

createFromXmlResource()期望一个类路径资源，该资源通常位于一个命名空间（= java程序包）中，例如"/org/foo/barSolverConfig.xml"，以避免在受到超级jarred或压缩压缩时出现麻烦。
