spring redis sentinel deployment

Introduction:

        Implement reids master slave mode to add sentinel monitoring, when the host goes down, the backup machine assumes the host identity for production work.

 

Implementation:

       1. First follow the spring redis integration http://see-you-again.iteye.com/admin/blogs/2323435 to complete the configuration in non-sentry monitoring mode.

       2. Modify the pom file as follows:
