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

spring的项目中有时候会报错:java.lang.IllegalStateException: BeanFactory not initialized or already closed - call ‘refresh‘ before accessing beans via the ApplicationContext

原因:spring初始化bean对象出错;1)xml的bean的id 有重复;

                                              2)如果是注解配置:可能是注解的名称有重复:

只需要将重复的bean 的id和重复的注解改了就行了;
