Introduction

To provide transparent cachning functionality, Spring introduces the Cache abstraction. The goal is to allow consistent use of caching with minimal impact on the code.

  • Applies caching to Java methods

    • Method result is cached if needed
    • Method should return the same output

  • Reducing number of method executions

    • Was method already invoked with given arguments?

  • Spring provides abstraction, so it requires Cache implementation (backing cache)

    • ConcurrentMap based cache
    • Ehcache based cache
    • Caffeine cache
    • GemFire based cache
    • JSR-107 cache

  • Spring has no special handling for multi-threaded code

  • To use caching you need to:

    • Declare what should be cached - Cachnig declaration
    • Backing cache - Cache configuration where the data is stored
