The Ehcache distributed cache used in the original project has the disadvantage of wasting memory and Ehcache using the memory of the JVM process, so memory usage is restricted.There is a scenario in the business where you sometimes want to update a business entity to invalidate the corresponding cache, in which case the update cache can only be one of the updated entities if the corresponding business enti

returns the same instance of the cached object to all callers. Therefore, these objects cannot be modified. This provides a very important performance advantage. A writable cache returns a copy of the cached object (via serialization).

How to persist data to disk when using Ehcache, and do not lose data after the application server restarts1. How to persist to diskWith Cache.flush (), Cache.flush () is called after each write to the cache, so that Ehcache writes the index (XXX.INDEX) back to disk. This allows the cache to be lost without worrying about whether or not the program exits abnormally.2, attach the configuration file modificati

The so-called cache, is the program or the system will often call the object in memory, so that it can be used to quickly call, do not have to create new duplicate instances. This can reduce system overhead and improve system efficiency.
