Spring中bean的配置

下面是bean配置中要用到的实体的类

package zhang.spring.enities;
public class Car {
	private String brand;
	private double price;
	private String color;
	public String getBrand() {
		return brand;
	}
	public void setBrand(String brand) {
		this.brand = brand;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}
	public String getColor() {
		return color;
	}
	public void setColor(String color) {
		this.color = color;
	}
	public Car(String brand, double price, String color) {
		super();
		this.brand = brand;
		this.price = price;
		this.color = color;
	}
	public Car() {
		// TODO Auto-generated constructor stub
	}
	@Override
	public String toString() {
		return "Car [brand=" + brand + ", price=" + price + ", color=" + color + "]";
	}
	
	
}
package zhang.spring.enities;

import java.util.List;
import java.util.Map;

public class Person {
	private String name;
	private int age;
	private double weight;
	private Car car;
	private List<Son> sons;
	private Map<String,Car> cars;
	
	public Map<String, Car> getCars() {
		return cars;
	}
	public void setCars(Map<String, Car> cars) {
		this.cars = cars;
	}
	public List<Son> getSons() {
		return sons;
	}
	public void setSons(List<Son> sons) {
		this.sons = sons;
	}
	public Car getCar() {
		return car;
	}
	public void setCar(Car car) {
		this.car = car;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public double getWeight() {
		return weight;
	}
	public void setWeight(double weight) {
		this.weight = weight;
	}
	
	public Person() {
		
	}
	public void show(){
		System.out.println("你好,我叫:"+this.name);
	}
	
	public Person(String name, int age) {
		super();
		this.name = name;
		this.age = age;
	}
	public Person(String name, int age, double weight) {
		super();
		this.name = name;
		this.age = age;
		this.weight = weight;
	}
	@Override
	public String toString() {
		return "Person [name=" + name + ", age=" + age + ", weight=" + weight + ", car=" + car + ", sons=" + sons + "]";
	}
	package zhang.spring.enities;

public class Son {
	private String sonName;
	private int age;
	private String sex;
	public String getSonName() {
		return sonName;
	}
	public void setSonName(String sonName) {
		this.sonName = sonName;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {

	}
	@Override
	public String toString() {
		return "Son [sonName=" + sonName + ", age=" + age + ", sex=" + sex + "]";
	}
	public Son() {
		// TODO Auto-generated constructor stub
	}

2.applicationContext.xml文件,中来配置bean
