# Lazy dependency access

Fields annotated with`@Inject(lazy=true)` will be resolved after the whole dependency tree was resolved. This way, when injecting these fields, each of the required dependencies are already resolved.

Note that, these fields will be `null` in the constructor. If you want to use these fields after initialization, check out the `Service lifecycles` section in the `Advanced usage` category.

```java
@Service
class ServiceA {
    @Inject(lazy = true)
    ServiceB serviceB;
}

@Service
class ServiceB {
    @Inject(lazy = true)
    ServiceA serviceA;
}
```

{% hint style="info" %}
Note that lazily injected fields are not accessible in the constructor, as they are resolved after the dependency tree construction.
