本文解析了一个关于Spring MVC启动时出现的FileNotFoundException异常，主要原因是未能正确加载db.properties配置文件。文章提供了两种解决方法：一是确保在applicationContext.xml中正确配置数据源；二是确认资源文件路径配置正确，并将其标记为资源根目录。

基本报错信息表现为:

可能性1:没有引入数据源
在applicationContext.xml添加数据源 (请根据自己的项目引用)

<context:property-placeholder location="classpath:db.properties"/>

可能性2：引入了数据源但是找不到文件

这个问题目前我只在idea中遇到,myEclipse中没出现过。

找到项目的资源文件(resources),查看是否是这种图标

如果不是则在文件上右键→ Mark Dirextory as

将文件属性设置为 Resources Root 后重新编译项目重试(我这边已经改过了，所以在上面看不到有Resources Root属性)
