spring框架（3）— spring集合类的注入

1.Car.java

package com.eniac.beans;

public class Car {
	private String type;
	private String factory;
	private double price;

	public Car(){
	}

	public Car(String type, String factory, double price) {
		super();
		this.type = type;
		this.factory = factory;
		this.price = price;
	}
	public String getType() {
		return type;
	}
	public void setType(String type) {
		this.type = type;
	}
	public String getFactory() {
		return factory;
	}
	public void setFactory(String factory) {
		this.factory = factory;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}
	@Override
	public String toString() {
		return "Car [type=" + type + ", factory=" + factory + ", price="
				+ price + "]";
	}
}

2.Person.java

package com.eniac.beans;

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

public class Person
{
	private String name;
	private int age;
	private List<Car> cars;
	private List<String> names;
	private Map<String, Car> maps;

	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 List<Car> getCars() {
		return cars;
	}
	public void setCars(List<Car> cars) {
		this.cars = cars;
	}
	public List<String> getNames() {
		return names;
	}
	public void setNames(List<String> names) {
		this.names = names;
	}
	public Map<String, Car> getMaps() {
		return maps;
	}
	public void setMaps(Map<String, Car> maps) {
		this.maps = maps;
	}
	@Override
	public String toString() {
		return "Person [name=" + name + ", age=" + age + ", cars=" + cars
				+ ", names=" + names + ", maps=" + maps + "]";
	}
}

　　1.使用了p命名空间；

　　2.通过使用<list>子标签，将list的值注入；

　　3.使用<map>子标签，将map的值注入。
