The data structures supported in Redis are much more than memcached, such as basic strings, hash tables, lists, collections, sortable sets, as well as the various operations on the data structure, which is an important reason for Redis to be popular.

Java Web projects, which do not rely on web containers for load balancing, must address session sharing issues. There are many online solutions, but I think the use of Spring-session +redis is the most efficient, do not have to reinvent the wheel,
