Migrate your spring version from 2.5 to >=3.2.3.
For Spring migration you need to do following changes -
1) In your pom.xml remove dependency for spring 2.5.6 and add dependency for spring new version.
2) Update 'xsi:schemaLocation' in beans tag of applicationcontet.xml file of your project.
e.g update http://www.springframework.org/schema/beans/spring-beans-2.5.xsd to http://www.springframework.org/schema/beans/spring-beans-3.2.xsd for spring 3.2.3 version.
3) Clean,build and re-deploy your project.
