Third-party cache implementations

Spring's SimpleCacheManager is ok for testing, but has no cache control options (overflow, eviction). So we have to use third-party alternatives like the following:

• Terracotta's EhCache
• Google's Guava and Caffeine
• Pivotal's Gemfire

Let's see one of the configurations of third-party cache managers.

Ehcache-based cache

Ehcache is one of the most popular cache providers. Spring allows you to integrate with Ehcache by configuring EhCacheCacheManager in the application. Take for example, the following Java configuration:

    @Bean 
    public CacheManager cacheManager(CacheManager ehCache) { 
      EhCacheCacheManager cmgr = new EhCacheCacheManager(); 
      cmgr.setCacheManager(ehCache); 
      return cmgr; 
    } 
    @Bean  
    public EhCacheManagerFactoryBean ehCacheManagerFactoryBean() { 
      EhCacheManagerFactoryBean eh = new EhCacheManagerFactoryBean(); 
      eh.setConfigLocation(new  
      ClassPathResource("resources/ehcache.xml")); 
      return eh; ...
