浅谈springioc实例化bean的三个方法

public class HelloWorld {
   
  public HelloWorld(){
    System.out.println("aaaa");
  }
   
  public void hello(){
    System.out.println("hello world");
  }
}

public class HelloWorldFactory {
  public static HelloWorld getInstance(){
    return new HelloWorld();
  }
}

<&＃63;xml version="1.0" encoding="UTF-8"&＃63;>

  
  
   
  
   

@Test
  public void test(){
    ApplicationContext cOntext= new ClassPathXmlApplicationContext("applicationContext.xml");
    HelloWorld world = (HelloWorld)context.getBean("helloWorld2");
    world.hello();
  }
