SpringBean_获取Spring加载的所有bean（实践）

一、查询代码

private static ApplicationContext ctx;
 
 
public static void main(String[] args) {
       try {
 
 
           ctx = new ClassPathXmlApplicationContext(
                   new String[]{
                           "classpath:spring/spring-dao.xml",
                           "classpath:spring/spring-biz.xml",
                           "classpath:spring/spring-service.xml",
                           "classpath:spring/spring.xml"
                   });
 
           listAllSpringBeans();
           
       } catch (Exception e) {
           e.printStackTrace();
         
       }
    }
 
   private static void listAllSpringBeans() {
       String[] beanNames = ctx.getBeanDefinitionNames();
       int allBeansCount = ctx.getBeanDefinitionCount();
 
       System.out.println("所有beans的数量是：" + allBeansCount);
       for (String beanName : beanNames) {
           Class<?> beanType = ctx.getType(beanName);
           Package beanPackage = beanType.getPackage();
 
           Object bean = ctx.getBean(beanName);
 
           System.out.println("BeanName:" + beanName);
           System.out.println("Bean的类型：" + beanType);
           System.out.println("Bean所在的包：" + beanPackage);
 
           System.out.println("
");
       }
   }

二、查询结果
