Question

我有几个课程如下：

public class ControllerA {

    @Autowired
    private UserService userService;

    protected void methodControllerA() {
       userService.findAll();
       .... 
    }   
}

public class ControllerB extends ControllerA {

    @Autowired
    private AccountService accountService;

    public void methodControllerB() {
        accountService.findAll();
        methodControllerA();    
    }       
}

我想测试 ControllerB.methodControllerB（）的行为，所以我按如下方式创建了Junit类：

@RunWith(MockitoJUnitRunner.class)
@ContextConfiguration(locations = {
    "classpath:services/testServiceContext.xml",
    "classpath:apply/applyController.xml",
    "classpath:testApplicationContext.xml",
    "classpath:testDatabaseMessageSource.xml",
    "classpath:controller/propertyeditors/propertyeditorsContext.xml"})
public class ControllerBTest {

    @Mock
    private AccountService accountService;

    @InjectMocks
    private ControllerB  controller;

    @Test
    public void methodControllerBTest() throws Exception {      

        controller = new ControllerB() {
            protected void methodControllerA() {                
            }
        };          
        controller.methodControllerB();
        asserts(); 
    }    

}

当然，当我实例化ControllerB（）时，accountService没有被模拟，所以当调用accountService时我得到一个nullpointer，但如果我没有实例化ControllerB（），我就不能覆盖methodControllerA（），所以我在这个方法里面的Userservice中得到了一个nullpointer ... 有任何想法吗？感谢

解决了！

AccountServiceImp accountService = mock(AccountServiceImp.class);
controller = new ControllerB() {
            protected void methodControllerA() {                
            }
};          
controller.setAccountService(accountService);
controller.methodControllerB();

从父类中模拟方法
