java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' befo

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

 

spring的項目中有時候會報錯：java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext

緣由：spring初始化bean對象出錯；1）xml的bean的id 有重複；

                                              2）若是是註解配置：多是註解的名稱有重複：

只須要將重複的bean 的id和重複的註解改了就好了；
