Spring之HelloWorld

package com.suse.spring.beans;public class HelloWorld {    private String name;    private String email;    public void setEmail(String email){        System.out.println("my email is:"+email);        this.email=email;    }    public void setName2(String name) {        System.out.println("IOC setName: " + name);        this.name = name;    }    public void hello() {        System.out.println("hello: ," + name+"  my email is: "+email);    }    public HelloWorld() {        System.out.println("HelloWorld Constructor... ");    }}

运行结果：
HelloWorld Constructor…
IOC setName: Spring
my email is:[e-mail]
