PowerMock 模拟静态无法模拟类

如何解决PowerMock 模拟静态无法模拟类

我有一个使用 power mock 运行的测试用例。下面是代码

ParamControllerTest.java

    @RunWith(powermockrunner.class)
    @PrepareForTest(XYZ.class)
    public class ParamControllerTest{
    
    private HttpServletRequest request;
    private ParamController paramController;
    private ParamVO2 paramVO2;
    private String userId = "123456";
    private String access = "re";
    
    @Mock
    private XYZdaoMock xYZdaoMock;
    
    @Test
        public void testAddSecty(){
            request = powermockito.mock(HttpServletRequest.class);
// You do get request value as HttpServletRequest
            powermockito.mockStatic(XYZ.class);
            when(XYZ.getId(request)).thenReturn(id);
            when(XYZ.getAccess(userId,"bcd")).thenReturn("re");
            when(XYZ.getId(request)).thenReturn("123456");
            when(xYZdaoMock.updateKey(paramVO2)).thenReturn(paramVO2);
            paramController.addParam(paramVO2);
            verify(xYZdaoMock).updateKey(paramVO2); 
            
        }
    }

ParamController.java

@Controller
@RequestMapping(value="/param")
@Transactional(propagation=Propagation.required,rollbackFor = Exception.class)
public class ParamController {
    
@RequestMapping(value="/abc",method = RequestMethod.POST)
    public @ResponseBody ParamVO addParam(@RequestBody ParamVO paramVO){
        ParamVO paramVO = null;
        String userId = XYZ.getId(request);
// userId result null as request is null and due to which after this it result in NullPointerException
        // Code
        return paramVO;             
        
    }
}

考虑到控制器中 userId 上的空指针，powermockito.mockStatic(XYZ.class) 我认为这是错误的。我读到了这个，显然这不适用于适当版本的 mockito 和 power mockito。我尝试注释掉 pom 中的 mockito 依赖项，使其不与 power mockito 的版本冲突，但它不起作用。以下是我尝试过的 power mockito 版本，但没有一个有效。使用的 Spring 版本是 4.3.19。 尝试的 Power Mockito 版本是 1.4.12，它在运行测试用例和 1.7.3 时给出了 XYZ.class 的初始化错误，结果是 NullPointerException，如上所示。
