Spring静态工厂与动态工厂的创建与配置

静态工厂创建对象：

一：通过静态工厂模式创建对象

package cn.jz.beans; public class Bean1 {    public void add(){        System.out.println("bean1 ........");    }}  package cn.jz.beans; public class Bean1_factory {    public static Bean1 getBean(){        return new Bean1();    }}二：通过实例工厂模式创建对象   package cn.jz.beans; public class Bean2 {    public void add(){        System.out.println("bean2 ........");    }}  package cn.jz.beans;` public class Bean2_factory {    public Bean2 getBean(){        return new Bean2();    }}

三：通过简单构造函数创建单例对象

package cn.jz.beans; public class Bean3 {    public void add(){        System.out.println("bean3 ........");    }}  package cn.jz.beans;  import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext; public class Test {     public static void main(String[] args){        ApplicationContext context =                 new ClassPathXmlApplicationContext("beans01.xml");        Bean1 b1 = (Bean1)context.getBean("bean1");        Bean2 b2 = (Bean2)context.getBean("bean2");        Bean3 b3 = (Bean3)context.getBean("bean3");        b1.add();        b2.add();        b3.add();        System.out.println(b1);        System.out.println(b2);        System.out.println(b3);    }            }
