我试过了:
@MockBean
private A a;
@InjectMocks
private B b;
@Before
public void executedBeforeEach() {
MockitoAnnotations.initMocks(this);
}

但有例外:
org.mockito.exceptions.base.MockitoException:
Cannot instantiate @InjectMocks field named 'B'.
You haven't provided the instance at field declaration so I tried to construct the instance.
However, I failed because: the type 'B' is an interface.

怎么做对?我在哪里犯错了?
您只需要自动装配B。通过使用批注,@MockBean
您将告诉测试Spring上下文用模拟替换实际类型A的实际bean,并且它将自动注入到包含的所有A中(即,在您的B bean中)。
@MockBean
private A a;
@Autowire
private B b;
