Creating a spring bean with Configuration annotation - spring

Question

guys, I want to register and inject a spring bean with the Configuration annotation but without success. Here is the bean I want to create on a abstract level:
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
}
}
Here is my Configuration class:
#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;
}
}
And I declare in the application context the configuration bean:
<bean class="configuration.package.BeanConfiguration"/>
So the the problem is that the spring container creates an BeanConfiguration object but the getMyBean() method is never hit, so my bean is never registered and when I try to inject it an exception telling me that the bean can not be autowired, so it is not injected(and that is normal, because the bean is not registered). Here is the stack trace

So I can't see why my bean is not registered, so if anyone can help I would be grateful.

Answer 1

The first problem is because you use private with inject and you dont have the set function, and the other problem is because you dont have the <bean class="....MyBean"/> in your xml configuration
