Spring框架——採用Java工程實現Hello World!的實現

package com.edu;

public class HelloBean {
	private String name;
	private String course;
	private Double score;
	public HelloBean(String name, String course, Double score) {
		super();
		this.name = name;
		this.course = course;
		this.score = score;
	}
	public HelloBean() {
		super();
		// TODO Auto-generated constructor stub
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getCourse() {
		return course;
	}
	public void setCourse(String course) {
		this.course = course;
	}
	public Double getScore() {
		return score;
	}
	public void setScore(Double score) {
		this.score = score;
	}
	public void show() {
		String s="姓名：  "+this.getName()+"    課程名："+this.getCourse()+"    成績："+this.getScore();
           System.out.println(s);	
 	}
