CarFactoryBean.java

package com.gong.spring.beans.factoryBean;import org.springframework.beans.factory.FactoryBean;public class CarFactoryBean implements FactoryBean<Car> {  private String name;  public void setName(String name) {    this.name = name;  }  //返回Bean的对象  @Override  public Car getObject() throws Exception {    // TODO Auto-generated method stub    return new Car(name,200000);  }  //返回bean的类型  @Override  public Class<?> getObjectType() {    // TODO Auto-generated method stub    return Car.class;  }  //是否是单例  @Override  public boolean isSingleton() {    // TODO Auto-generated method stub    return true;  }}
