Mockito、Java 9 和 java.lang.ClassNotFoundException:sun.reflect.ReflectionFactory

2022-01-14 00:00:00 mockito java wildfly java-9

我的项目是一个使用 Mockito 测试库的 Wildfly 13 应用程序.该应用程序未使用 Java 9 模块结构.只要服务器在 Java 8 上运行，测试就可以正常工作，但是一旦我们升级到 Java 9，它们就会失败，并出现以下异常:

My project is a Wildfly 13 application which uses Mockito testing library. The app is not using Java 9 module structure. As long as the server ran on Java 8 the tests worked fine, but once we upgraded to Java 9 they failed with the following 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.<init>(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:

I tried all kinds of options and combinations:

使用 Java 8、9、10 编译
使用最新版本的 OpenJDK 9 和 10 运行
设置编译器和虚拟机选项 --add-modules jdk.unsupported 和 --add-exports jdk.unsupported/sun.reflect=ALL-UNNAMED"

总是同样的错误.我没有想法.

Always the same error. I'm out of ideas.

--show-module-resolution的结果

推荐答案

随着更多的挖掘，我在找到了解决方案https://developer.jboss.org/thread/278334 指向我 https://docs.jboss.org/author/display/WFLY10/Class+Loading+in+WildFly.文章有一个标题为访问 JDK 类"的部分，其中指出并非所有类默认都可用于部署，您需要将它们添加到 jboss-deployment-structure.xml 以使它们可用.

With more digging I found the solution at https://developer.jboss.org/thread/278334 which pointed me to https://docs.jboss.org/author/display/WFLY10/Class+Loading+in+WildFly. The article has a section titled "Accessing JDK classes" which states that not all classes are available to deployment by default, and you need to add them to jboss-deployment-structure.xml to make them available.

就我而言:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1"> <deployment> <dependencies> <system export="true"> <paths> <path name="sun/reflect"/> </paths> </system> </dependencies> </deployment> </jboss-deployment-structure>

此解决方案适用于

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
Mockito 1.10.19(我尝试了 2.20.0 但出现了新错误)
