Spring Factory Bean

Spring Factory Bean

<!--     通过FactoryBean来配置Bean的实例    class:指向FactoryBean的全类名    property:配置FactoryBean的属性    但实际返回的实例却是FactoryBean的getObject()方法返回的实例     -->    <bean id="dog" class="com.metadata.factorybean.DogFactory">        <property name="name" value="kk"></property>    </bean>

public class DogFactory implements FactoryBean<Dog>{    private String name;    public void setName(String name) {        this.name = name;    }    //返回Bean的对象    @Override    public Dog getObject() throws Exception {        // TODO Auto-generated method stub        //return new Dog("dd", "blue");        return new Dog(name, "green");    }    //返回Bean的类型    @Override    public Class<?> getObjectType() {        return Dog.class;    }    //是否单例    @Override    public boolean isSingleton() {        return true;    }}
