Создание весеннего компонента с аннотацией конфигурации

Вопрос:

ребята, я хочу зарегистрироваться и вставить весенний боб с аннотацией конфигурации, но безуспешно. Вот боб, который я хочу создать на абстрактном уровне:

public class MyBean{

private AnotherBean anotherBean;

private String someString;

public MyBean(AnotherBean anotherBean, String someString) {
this.anotherBean= anotherBean;
this.someString= someString;
}

public MyBean(){}

public MyPojo someMethod(MyPojo oject, final String anyString) {
//some logic
}
}

Вот мой класс конфигурации:

@Configuration
public class BeanConfiguration {

private static final String SOME_STRING = "someString";

@Inject
@Qualifier("anotherBean")
private AnotherBean otherBean;


@Bean(name = "myBean")
public MyBean getMyBean(){
MyBean myBean= new MyBean(otherBean, SOME_STRING );
return myBean;
}
}

И я объявляю в контексте приложения конфигурационный компонент:

<bean class="configuration.package.BeanConfiguration"/>

Таким образом, проблема заключается в том, что весенний контейнер создает объект BeanConfiguration, но метод getMyBean() никогда не попадает, поэтому мой компонент никогда не регистрируется, и когда я пытаюсь ввести его исключение, говорящее мне, что bean-компонент не может быть автообновлен, не вводится (и это нормально, потому что компонент не зарегистрирован). Вот трассировка стека

Поэтому я не понимаю, почему мой боб не зарегистрирован, поэтому, если кто-то может помочь, я буду благодарен.

Ответ №1

Первая проблема заключается в том, что вы используете private с инъекцией, и у вас нет функции set, а другая проблема заключается в том, что у вас нет <bean class="....MyBean"/> в вашей конфигурации xml
