Mockito，Java 9和java.lang.ClassNotFoundException：sun.reflect.ReflectionFactory [英] Mockito, Java 9 and java.lang.ClassNotFoundException: sun.reflect.ReflectionFactory

问题描述

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:

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进行编译


• 使用最新版本的OpenJDK 9运行和10


• 设置编译器和vm选项--add-modules jdk.unsupported和--add-export s jdk.unsupported / sun.reflect = ALL-UNNAMED

始终存在相同的错误。我没有想法。

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

推荐答案

随着更多的挖掘，我在 https://developer.jboss.org/thread/278334 它指向我 https://docs.jboss.org /作者/显示/ WFLY10 /类+ +加载+中 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 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.

在我的情况下：

<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编译的应用程序


• Mockito 1.10 .19（我试过2.20.0但是有新的错误）
