Mockito + Spring + @PostConstruct, mock initialization error, why is @PostConstruct called?
提问by Whimusical
I have a set up like:
我有一个类似的设置：
Beanclass:
豆类：
private final Map<String, String> configCache = new HashMap<>();
@PostConstruct
private void fillCache() { (...) configCache.clear();}
TestConfigclass:
测试配置类：
@Bean
@Order(Ordered.HIGHEST_PRECEDENCE)
@Primary
public Bean beanMock() {
return Mockito.mock(Bean.class);
}
Testclass: which @Autowiresthe bean.
测试类：其中@Autowires的bean。
It seems when Mockito is creating the mock in TestConfig, it calls @PostConstruct which in turn seems to be called before the map field is initialized so it throws an exception.
似乎当 Mockito 在 TestConfig 中创建模拟时，它调用 @PostConstruct 似乎在初始化 map 字段之前调用它，因此它抛出异常。
My question is:
我的问题是：
- Why does Mockito call @PostConstruct?
- How can I disable @PostConstruct for mocking?
- 为什么 Mockito 调用@PostConstruct？
- 如何禁用@PostConstruct 进行模拟？
EDIT: Apparently the call is done after the instantiation just before Spring retrns the bean from a Config's @Bean method
编辑：显然调用是在 Spring 从 Config 的 @Bean 方法中重新获取 bean 之前的实例化之后完成的

Mockito isn't calling @PostConstruct-- Spring is. You say that in your test you use @Autowired, which is not a Mockito annotation.
Mockito 不是在调用——Spring@PostConstruct是。您说在您的测试中使用了@Autowired，这不是 Mockito 注释。
If you meant to use @Mock, you'll find that Mockito won't call your @PostConstructmethod.
如果您打算使用@Mock，您会发现 Mockito 不会调用您的@PostConstruct方法。
In other words, write your test class like this:
换句话说，像这样编写你的测试类：
@Mock Bean myBean;
@Before
public void before() {
MockitoAnnotations.initMocks();
}
