spring 中 静态工厂与实例工厂

静态工厂与实例工厂如下：

applicationContext.xml

<!-- 静态工厂 -->
<bean id="person1" class="demo.PersonFactory" factory-method="creatPerson1"></bean>

<!-- 实例工厂 -->
<bean id="personFactory" class="demo.PersonFactory"></bean>
<bean id="person2" factory-bean="personFactory" factory-method="createPerson2"></bean>

PersonFactory.java

public class PersonFactory {
    /**
     * 静态工厂方法
     * @return
     */
    public static Person creatPerson1(){
        System.out.println("静态工厂创建Person...");
        return new Person();
    }
 
 	/**
     * 实例工厂方法
     * @return
     */
    public Person createPerson2(){
        System.out.println("实例工厂创建Person...");
        return new Person();
    }

}
