java - 单元测试中的@Autowire 似乎不起作用

Question

我有一个使用 Mockito 和 Spring 4 的单元测试设置。我的测试如下所示:

@ContextConfiguration(classes = {
        MyTestConfig.class,
        SecurityConfig.class,
        OAuth2Config.class
})
@RunWith(MockitoJUnitRunner.class)
public class ControllerAccessTests {

    private MockMvc mockMvc;

    @Autowired
    private FilterChainProxy springSecurityFilterChain;

    @Mock
    private CreditCardPaymentService creditCardPaymentService;
    @InjectMocks
    private CreditCardRestController creditCardRestController;

    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders
                .standaloneSetup(creditCardRestController)
                .apply(springSecurity(springSecurityFilterChain))
                .build();
        when(creditCardPaymentService.doPreAuthPayment(any())).thenReturn(null);
    }

    @Test
    //.... some unit tests

使用如下所示的配置文件:

@Configuration
public class MyTestConfig {

    @Bean
    public FilterChainProxy springSecurityFilterChain(){
        AntPathRequestMatcher matcher = new AntPathRequestMatcher("/**");
        DefaultSecurityFilterChain chain = new DefaultSecurityFilterChain(matcher);
        return new FilterChainProxy(chain);
    }

}

当我开始单元测试时 springSecurityFilterChain 是空的，所以看起来配置文件 MyTestConfig 似乎没有被加载。有任何想法吗？

Answer 1

如果你想使用 mockito 注释和 spring 注入(inject)，那么:

1) 使用@RunWith(SpringJUnit4ClassRunner.class)

2) 创建一个初始化方法:

@Before
public void init(){
 MockitoAnnotations.initMocks(this);
}
