public class Poem {private String id;private String name;public Poem(String id,String name){this.id = id;this.name = name;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}

public class Test {public static void main(String[] args) throws Exception {ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");Juggler juggler = (Juggler) context.getBean("dudk");juggler.perform();}}
