本文介绍了迁移到 JDK 11 后 Spring Boot 测试中的 Mockito 错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我刚刚迁移到 JDK 11 以使用最新的 Java LTS 版本.如果我将 Eclipse 中的执行 JRE 从 10 更改为 11(并且仅在那时)，当我尝试运行我的测试时，我会得到以下异常堆栈跟踪.
I have just migrated to JDK 11 in order to use the latest Java LTS version. If I change the execution JRE in Eclipse from 10 to 11 (and only then), when I try to run my tests, I get the following exception stacktrace.
请注意，如果我切换回 jdk-10，一切都会按预期工作.我使用 Spring Boot，我的测试也使用 Mockito.我的 pom.xml 也显示在这里.
Please note that everything works as expected if I switch back to jdk-10. I use Spring Boot and my tests also use Mockito. My pom.xml is also shown here.
Spring Boot 和/或 Mockito 与 jdk-11 之间是否存在已知的不兼容性?pom.xml 中可能缺少另一个引用?
Is there a known incompatibility between Spring Boot and/or Mockito with jdk-11? Perhaps another reference missing in pom.xml?

推荐答案
同样的问题.将 Mockito 2.22.0 添加到依赖项.一切似乎都正常.
Was the same problem.Add Mockito 2.22.0 to dependencies. Everything seems to work.
compile group: 'org.mockito', name: 'mockito-core', version: '2.22.0'
