Hope adequate guidance, tried various search engines to search for a solution.

------ Solution ------------------------------------ --------
this jar and you should be in the spring configuration file does not match the declared result .
xmlns: context = "http://www.springframework.org/schema/context"
------ For reference only -------------- -------------------------
If you encounter this problem , we should pay attention to see you in a jar under the META-INF directory is not have these two files : spring-handlers and spring-schemas!

------ For reference only ---------------------------------- -----

there ah. But spring.schemas files there are many duplicate jar, such as :
http \ :/ / www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http \ :/ / www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http \ :/ / www.springframework.org/schema/context/spring-context-3.1.xsd=org/springframework/context/config/spring-context-3.1.xsd
