## java.lang.IllegalStateException:错误 修改
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；
