BeanFactory not initialized or already closed

java.lang.IllegalStateException: BeanFactory not initialized or already closed - call ‘refresh’ before accessing beans via the ApplicationContext

原因

BeanFactory 未初始化或已关闭

BeanFactory not initialized or already closed

在通过应用程序上下文访问 bean 之前调用“刷新”

call ‘refresh’ before accessing beans via the ApplicationContext

解决方法：

未指定applicationContext.xml配置文件

错误写法：

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext();

正确写法：

ApplicationContext context = new ClassPathXmlApplicationContext("applicicationContext.xml");
