Tomcat startup takes huge time with my Spring application

Question

I have Spring project which produces 42MB war file. Whenever I deploy it in a server it is taking more than an hour with tomcat 7. Even in development environment it is consuming more than 20 mins in the local environment if we make any changes in it.

I suspect I have a major mistake.
