How to @Autowire services in SpringBoot

Question

Good day, guys. I have a question about autowiring services into my classes when using Springboot. All of the examples I have seen on the Internet as well as in the Springboot specification do something of the like (taking an excerpt from the Springboot version 1.5.7 specification):

package com.example.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class DatabaseAccountService implements AccountService {
private final RiskAssessor riskAssessor;

@Autowired
public DatabaseAccountService(RiskAssessor riskAssessor) {
this.riskAssessor = riskAssessor;
}
// ...
}

This is a class that injects a property through its constructor, by means of @Autowiring the constructor. Another form is to @Autowire the property like this:

@Autowired
private final RiskAssessor riskAssessor

But, where I work, for these two methods to work, I have been told that I need to use this method:

 applicationContext.getAutowireCapableBeanFactory().autowireBean(Object.class)

They have told me that I need this in order for the @Autowired annotation to work.

Now my question to you is: why is there no simple annotation that allows the @Autowire to function correctly? (Something like @AutowiredClass). The above method is too verbose and hard to remember, so surely there must be a better way to make @Autowired work on classes in order to inject services, just like we do in Grails where we just say def someService and it is automatically injected.

Answer 1

If you want properly use @Autowired in your spring-boot application, you must do next steps:

1. Add @SpringBootApplicationto your main class
2. Add @Service or @Component annotation to class you want inject
3. Use one of two ways that you describe in question, to autowire
