Mockito，Java 9和java.lang.ClassNotFoundException：sun.reflect.ReflectionFactory
我的项目是Wildfly 13应用程序，它使用Mockito测试库。 该应用程序不使用Java 9模块结构。 只要服务器在Java 8上运行，测试工作正常，但是一旦我们升级到Java 9，它们就会失败并出现以下exception：
org.objenesis.ObjenesisException: java.lang.ClassNotFoundException: sun.reflect.ReflectionFactory from [Module "test.war" from Service Module Loader] at test.war//org.objenesis.instantiator.sun.SunReflectionFactoryHelper.getReflectionFactoryClass(SunReflectionFactoryHelper.java:63) at test.war//org.objenesis.instantiator.sun.SunReflectionFactoryHelper.newConstructorForSerialization(SunReflectionFactoryHelper.java:37) at test.war//org.objenesis.instantiator.sun.SunReflectionFactoryInstantiator.(SunReflectionFactoryInstantiator.java:41) at test.war//org.objenesis.strategy.StdInstantiatorStrategy.newInstantiatorOf(StdInstantiatorStrategy.java:68) at test.war//org.objenesis.ObjenesisBase.getInstantiatorOf(ObjenesisBase.java:94) at test.war//org.objenesis.ObjenesisBase.newInstance(ObjenesisBase.java:73) at test.war//org.mockito.internal.creation.instance.ObjenesisInstantiator.newInstance(ObjenesisInstantiator.java:19) at test.war//org.mockito.internal.creation.bytebuddy.SubclassByteBuddyMockMaker.createMock(SubclassByteBuddyMockMaker.java:47) at test.war//org.mockito.internal.creation.bytebuddy.ByteBuddyMockMaker.createMock(ByteBuddyMockMaker.java:25) at test.war//org.mockito.internal.util.MockUtil.createMock(MockUtil.java:35) at test.war//org.mockito.internal.MockitoCore.mock(MockitoCore.java:68) at test.war//org.mockito.Mockito.mock(Mockito.java:1895) at test.war//org.mockito.Mockito.mock(Mockito.java:1804) at test.war//application code... 我尝试了各种选项和组合：
- 使用Java 8,9,10进行编译
- 运行最新版本的OpenJDK 9和10
- 设置编译器和vm选项–add-modules jdk.unsupported和–add-exports jdk.unsupported / sun.reflect = ALL-UNNAMED“
总是一样的错误。 我没有想法。

随着更多的挖掘，我在https://developer.jboss.org/thread/278334找到了解决方案，它指向了https://docs.jboss.org/author/display/WFLY10/Class+Loading+in+WildFly 。 本文有一个标题为“访问JDK类”的部分，其中指出默认情况下并非所有类都可用于部署，您需要将它们添加到jboss-deployment-structure.xml以使其可用。
就我而言：
该解决方案适用于
- Wildfly 13，在Java 10.0.2上运行（9.0.4也可以）
- 使用Java 8编译的应用程序
- Mockito 1.10.19（我试过2.20.0但是有新的错误）
我认为问题可能是您使用的是早期版本的Java 9.在某些早期版本中，访问sun.reflect库时出现问题。 尝试将您的Java 9版本更新为版本9-ea+115之后的更高版本， 这是对类似（尽管不同）问题的答案中的建议。
