spring问题：info: no spring webapplicationinitializer types detected on classpath

问题：我的Eclipse环境用的JDK 8，项目是JDK 7，在jetty中启动项目时报错：INFO: No Spring WebApplicationInitializer types detected

解决：确定项目编译时的jdk版本，更改Eclipse编译用的jdk版本即可

参考http://stackoverflow.com/questions/22938689/info-no-spring-webapplicationinitializer-types-detected-on-classpath

I found the error: I have a library that it was built using jdk 1.6. The Spring main controller and components are in this library. And how I use jdk 1.7, It does not find the classes built in 1.6.
The solution was built all using “compiler compliance level: 1.7” and “Generated .class files compatibility: 1.6”, “Source compatibility: 1.6”.
I setup this option in Eclipse: PreferencesJavaCompiler.
