Hi,
Here are the steps to add Spring 4 support to your project :
1. To remove the Spring 3.1 library from the project, select ‘Disable Library Configuration’ on the spring facet configuration page instead of ‘MyEclipse Library’. Applying the changes will automatically remove the added Spring 3.1 libraries from the existing project.Here is the screenshot for your reference :
2. You should download the required Spring 4 jars from the SpringSource site. Create a user library (window > preferences > java > buildpath > user libraries) and add the Spring 4 jars to it.
3. Add the user library to the project’s build path.
Let us know if you see any issues.
