根据报错信息翻译过来：在类工厂未被实例化或已被关闭-- 在通过applicationcontent进入beans之前刷新（个人自行翻译，理解为主） 推断应该是spring文件读取的问题，首先检查配置路径：
项目的一些信息
解决：
<!-- 配置spring容器加载配置文件的位置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
路径前：添加classpath
ps.classpath 与classpath*：区别:
