I am new to spring boot.
I am trying to understand Dependency Injection. I created a @Component bean and try to get it’s instance object into a simple POJO class.

Let’s take a look at example:

// Planet.java
@Component
class Planet() {
   private Long planetId;
   private String planetName;
   
   // ... getter-setter and constructor
}

since Planet object is annotated with @Component so it will be created by spring context container.
Now I have created a simple POJO class….

// Species.java
class Species() {
   private Long spId;
   private String spName;
   
   // I want to get the object of Planet from container
   @Autowired
   private Planet planet;

   // getter-setter and constructor
}

Now when I create my Species object with new keyword(new Species()) then…

1. Planet Object is created by container as expected.
2. But In my Species object planet property instead of referencing Planet object it reference to a null value (not expected)..

Since I am Autowiring planet property, it should get that object from container but It is not getting that object. Please let me know Where I am doing something wrong..

I also tried to create beans using @Configuaration but still it’s not working..
