FileNotFoundException与PowerMock + Drools + JBoss

Question

有没有人使用过“ PowerMock + Drools + JBoss”组合？

当我尝试在JUnit测试（JUnit 4.10）中使用单元测试Drools规则时，我会加载drl规则knolage kobtext：

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("com/mycompany/myproject/rooles.drl"), ResourceType.DRL);

而且效果很好。 org.drools.io.impl.ClassPathResource包含3个类加载器：

• java.net.FactoryURLClassLoader
• org.jboss.mx.loading.UnifiedClassLoader
• Sun.misc.Launcher

但是当我添加

@RunWith(org.powermock.modules.junit4.PowerMockRunner.class)

单元测试org.drools.io.impl.ClassPathResource包含2个类加载器：

• org.powermock.core.classloader.MockClassLoader
• Sun.misc.Launcher

并且测试失败并显示java.io.FileNotFoundException：

java.lang.RuntimeException: java.io.FileNotFoundException: 'com/mycompany/myproject/rooles.drl' cannot be opened because it does not exist 
at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:638) 
at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28)
...
Caused by: java.io.FileNotFoundException: 'com/wiley/cms/jqa/service/lifecycle/lifecycle.drl' cannot be opened because it does not exist

at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:352)

...

有人可以建议如何避免这个问题吗？

解决方案是添加@PowerMockIgnore（“ org.drools。*”）批注。
