迁移我的JAVA EE应用程序后。 （从Spring到Maven的Spring Web模型 - 视图 - 控制器（MVC）框架）我在迁移工作正常之前执行Junit测试时遇到一些错误
org.powermock.api.mockito.ClassNotPreparedException:
The class org.springframework.web.util.WebUtils not prepared for test.
To prepare this class, add class to the '@PrepareForTest' annotation.
In case if you don't use this annotation, add the annotation on class or method level.

答案 0 :(得分：3)
尝试 @RunWith(PowerMockRunner.class) 而不是@RunWith（MockitoJUnitRunner.class）
