JSR 330's javax.inject.@Inject annotation can be used in place of Spring's @Autowired annotation
Starting with Spring 3.0, Spring offers support for JSR 330 standard annotations (Dependency Injection). Those annotations are scanned in the same way as the Spring annotations.
Example
package com.logicbig.example;
public class GreetingService {
public String getGreeting(String name) {
return "Hi there, " + name;
}
}
Using @Inject annotation
package com.logicbig.example;
import javax.inject.Inject;
public class Greeter {
@Inject
private GreetingService greetingService;
public void showGreeting(String name){
System.out.println(greetingService.getGreeting(name));
}
}
Defining beans and running the example app
package com.logicbig.example;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class AppRunner {
@Bean
public GreetingService greetingService() {
return new GreetingService();
}
@Bean
public Greeter greeter() {
return new Greeter();
}
public static void main(String... strings) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(AppRunner.class);
Greeter greeter = context.getBean(Greeter.class);
greeter.showGreeting("Joe");
}
}
Output
Hi there, Joe
