Spring uses JavaConfig to implement configuration

package ;

import ;
import ;
//It means that this class is registered in the container by Spring@Component
public class User {
 @Value("lixin")
 private String name;

 public String getName() {
   return name;
 }

 public void setName(String name) {
    = name;
 }

 @Override
 public String toString() {
   return "User{" +
       "name='" + name + '\'' +
       '}';
 }
}

package ;

import ;
import ;
import ;
import ;

//This will also be hosted by the Spring container, because it is originally a @Component// @Configuration represents a class, just like what we were before@Configuration
@ComponentScan("")
public class LiConfig {
  //Register a bean, which is equivalent to a bean tag written in xml  //The name of this method is equivalent to the ID attribute in the bean tag  //The return value of the method is equivalent to the class attribute in the bean tag  @Bean
  public User getUser(){
    return new User();  //It is to inject the object into the bean  }
}

import ;
import ;
import ;
import ;

public class MyTest {
  public static void main(String[] args) {
    //If we use the configuration class method completely, we can only get the container through the AnnotationConfig context    // Then load it by configuring the class object!    ApplicationContext context=new AnnotationConfigApplicationContext();
    User getUser= (User) ("user");
    (());
  }
