bean生命周期测试

             Spring_bean生命周期测试

1.概述
Spring框架是一个开源的IOC,AOP框架,IOC容器装配了各种对象,那么他的创建销毁过程是咋样的呢?
下面展示一些 内联代码片。

import com.atguigu.pojo.Dept;
import org.junit.Test;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;


   public class TestScope {
    @Test
    //获取容器对象
    //原始  ApplicationContext ioc = new ClassPathXmlApplicationContext("applicationContext_scope.xml");
    public void testScope() {
        ConfigurableApplicationContext ioc = new ClassPathXmlApplicationContext("applicationContext_scope.xml");

//        Dept dept101 = ioc.getBean("dept101", Dept.class);
//        Dept dept101_2 = ioc.getBean("dept101", Dept.class);
//
//        //测试bean的作用域
//        System.out.println("是否是一个对象"+(dept101 == dept101_2));
        
        //测试bean的生命周期
        System.out.println(ioc);
        Dept dept102 = ioc.getBean("dept102", Dept.class);
        System.out.println("4.dept102" +dept102);
        //关闭容器对象
        ioc.close();

    }
}
