以上是关于applicationContext.xml简单笔记的主要内容，如果未能解决你的问题，请参考以下文章
spring框架的applicationContext.xml有一点不明白
事务配置在applicationContext.xml文件中不起作用，控制不了异常回滚
applicationContext.xml (系统找不到指定的文件)
ApplicationContext详解以及多个ApplicationContext.xml的相互引用
使用带有 Maven 结构的 @ContextConfiguration("/applicationContext.xml") “加载 ApplicationContext 失败”
在 Spring ApplicationContext 中设置 PropertyPlaceholderConfigurer 相对于 applicationContext.xml 的位置
