package com.spring.test; public class Person { private String name; private String context; public String getName() { return name; } public Person(String name, String context) { this.name = name; this.context = context; } public String getContext() { return context; } public void say() { System.out.println(name + " " + context); } }

 

package com.spring.test; public class Show { private Person person; public Person getPerson() { return person; } public void setPerson(Person person) { this.person = person; } public void show() { person.say(); } } package com.spring.test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Test { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); Show show = (Show)context.getBean("show"); show.show(); Person person = new Person("Hello", "Spring"); Show show1 = new Show(); show1.setPerson(person); show1.show(); } }
