在配置文件出现如下错误

Referenced file contains errors (project-aware://maven_demo1/org/springframework/beans/factory/xml/spring-beans-4.0.xsd). For more information, right click on the message in the Problems View and select "Show Details..."

这种错误是属于配置文件的验证错误，实际上并不影响项目的正常运行.新建的maven项目可以跑通，但过一会配置文件就会报此错，经过几番查阅，找到了解决办法。

操作步骤：Window--> Preferences  搜索 Validation

经过如上错误，配置文件不再报错了
