由于版本不匹配，从Java 8迁移到Java 17和Spring 6 JUnit4失败

您需要升级/添加PowerMock&；Mockito的以下依赖项才能支持JDK 17:

• powermock-module-junit4从1.6.6到2.0.9
• powermock-api-mockito (1.6.6)%至powermock-api-mockito2 (2.0.9)%
• 需要添加更新版本的javassist.将javassist版更新为最新的(3.29.2-GA)版(在 compose 答案时).

Note:在JDK 17上运行测试时可能会遇到此错误:

Unable to make protected native java.lang.Object java.lang.Object.clone() throws java.lang.CloneNotSupportedException accessible: module java.base does not "opens java.lang" to unnamed module

为了避免这种情况，您需要在运行此程序时通过添加这个--add-opens java.base/java.lang=ALL-UNNAMED到maven-surefire-plugin来告诉maven.

Another point to be noted:不需要单独添加Mockito依赖项.powermock-api-mockito2与mockito-core相辅相成.

这应该行得通.我已经在我的本地上测试过了，它起作用了.
