有时候采用编码的方式得到bean会更简单些。
CarBeanFactory.java
public class CarFactoryBean implements FactoryBean<Car> { private String carInfo; public String getCarInfo() { return carInfo; } public void setCarInfo(String carInfo) { this.carInfo = carInfo; } public Car getObject() throws Exception { Car car = new Car(); String[] infos = carInfo.split(","); car.setBrand(infos[0]); car.setMaxSpeed(Integer.parseInt(infos[1])); car.setPrice(Double.parseDouble(infos[2])); return car; } public Class<Car> getObjectType() { return Car.class; } public boolean isSingleton() { return false; } } 配置文件要这样写： <bean id="car1" class="com.baobaotao.fb.CarFactoryBean" p:carInfo="红旗CA72,200,20000.00"/> 记得实现implements FactoryBean<T>接口，然后调用的时候，便会主动去找getObject()方法了，返回的是Bean，而不是这个Factory本身。When you need to ask a container for an actual FactoryBean instance itself instead of the bean it produces, preface the bean’s id with the ampersand symbol ( &) when calling the getBean() method of the ApplicationContext. So for a given FactoryBean with an id of myBean, invoking getBean("myBean") on the container returns the product of the FactoryBean; whereas, invoking getBean("&myBean") returns the FactoryBean instance itself.
