PowerMock抛出java.lang.ExceptionInInitializeError 我正在使用Powermock+Mockito2+JUnit4对一个类进行单元测试。

当我尝试运行

apicreatorfacadempltest.java

时，它不起作用，抛出

java.lang.ExceptionInInitializerRor

。我不知道怎么修理它。有人能指出我犯了什么错误吗

import static org.powermock.api.mockito.PowerMockito.mock;

@RunWith(PowerMockRunner.class)
@PrepareForTest({HttpUtil.class})
public class ApiCreatorFacadeImplTest {

    private ServiceVersionFacade serviceVersionFacade;
    private ServiceFacade serviceFacade;

    private ApiCreatorFacadeImpl apiCreatorService;

    @Before
    public void setUp() {
        apiCreatorService = new ApiCreatorFacadeImpl();
        // mock ApiCreatorFacadeImpl fields
        serviceVersionFacade = mock(ServiceVersionFacade.class);
        serviceFacade = mock(ServiceFacade.class);
        // inject fields to apiCreatorService
        Whitebox.setInternalState(apiCreatorService, "serviceVersionFacade", serviceVersionFacade);
        Whitebox.setInternalState(apiCreatorService, "serviceFacade", serviceFacade);
    }

    @Test
    public void createHsfTypeApi() {
        // do nothing
    }

    @Test
    public void getApiTestParam() {
        // do nothing
    }
}

可能的原因是Powermockito，Mockito的版本冲突。你能检查一下Powermockito，mockito支持的版本吗。你可以看看

我也有同样的问题。这是因为Mockito库的版本不兼容。如果您已经在使用mockito 1.x，那么应该使用powermock-api-mockito，而在使用mockito 2.x时应该使用powermock-api-mockito2

---

例如，如果您正在使用Spring Boot和Spring Boot starter测试依赖项，那么您的项目已经包含Mockito依赖项，请检查Spring Boot父级的BOM文件（包含依赖项版本的pom文件）中的Mockito版本。

@HomJie I也有相同的错误，我只使用了两个依赖项powermock-module-junit4 1.6.4和powermock-api-mockito 1.6.4
