SpringContext ApplicationContextInitializer Arayüzü - Extension Point

Giriş

Şeklen şöyle. Henüz daha SpringContext yüklenmeden çağrılır

Açıklaması şöyle

You can see that the spring container has not been initialized at this time. If your extension takes effect, 

there are two ways:

(1) In the startup class, use the springApplication.addInitializers(new TestApplicationContextInitializer()) statement to add

(2) Configuration file configuration context.initializer.classes=com.example.demo.TestApplicationContextInitialize

Örnek

Şöyle yaparız

public class TestApplicationContextInitializer implements ApplicationContextInitializer {
  @Override
  public void initialize(ConfigurableApplicationContext applicationContext) {
    ...
  }
}
