工厂方法配置，

bean的配置方式：通过全类名（反射），通过工厂方法（静态工厂方法&实例工厂方法），FactoryBean

静态工厂方法

package com.hous.factory;

import java.util.HashMap;
import java.util.Map;

import com.hous.spring.Car;

public class StaticCarFactory {
	private static Map<String, Car> cars = new HashMap<String, Car>();

	static {
		cars.put("qirui", new Car("qirui", 200000));
		cars.put("hanma", new Car("hanma", 100000));
	}

	/**
	 * 静态工厂方法
	 * 
	 * @param name
	 * @return
	 */
	public static Car getCar(String name) {
		return cars.get(name);
	}

}

实例工厂方法

package com.hous.factory;

import java.util.HashMap;
import java.util.Map;

import com.hous.spring.Car;

/**
 * 实例工厂方法需要创建工厂本身，再调用工厂实例方法返回bean实例
 *
 */
public class InstanceCarFactory {
	private Map<String, Car> cars = null;

	public InstanceCarFactory() {
		this.cars = new HashMap<String, Car>();
		cars.put("qirui", new Car("qirui", 200000));
		cars.put("luhu", new Car("luhu", 100000));
	}

	public Car getCar(String brand) {
		return cars.get(brand);
	}

}

 FactoryBean配置

package com.hous.factory;

import org.springframework.beans.factory.FactoryBean;

import com.hous.spring.Car;

/**
 * 自定义FactoryBean实现接口
 * @author Administrator
 *
 */
public class CarFactoryBean implements FactoryBean<Car> {
	
	private String brand;
	
	public String getBrand() {
		return brand;
	}

	public void setBrand(String brand) {
		this.brand = brand;
	}

	@Override
	public Car getObject() throws Exception {
		return new Car(brand, 5000);
	}

	@Override
	public Class<?> getObjectType() {
		return Car.class;
	}

	@Override
	public boolean isSingleton() {
		return true;
	}

}
