The backup cache of the JCS index disk is an optional plug-in. It mainly aims to provide a second-level cache to reduce the cache pressure on the memory. When the memory cache exceeds the maximum value, the cache processing checks whether "disk" backup cache is configured for the storage area. If the index disk backup cache is used, the cache center saves the items deleted from the memory to the disk.

JCS is an object cache that caches Java objects to Improve the access efficiency of frequently accessed Java objects. JCs accesses an object based on the unique identifier of the object. For example, it can be accessed Based on the hashcode of the object. For hibernate, JCs can be used to cache the query results, so that when the same data is accessed next time,
JCS (Java Caching System) project: http://commons.apache.org/proper/commons-jcs/index.htmlJCS is a distributed cache system written in Java. It is designed to speed up applications by providing a means to manage the various dynamic cache data , which is a composite buffer tool that is said to be beyond simple object caches, which can buffer objects into memory, hard disk (local disk, network address disk, d
To make a product and want the product to be distributed, you have to study the distributed cache.
There are many open-source projects for caching. Through testing, JCS is the easiest to configure and use, so it is used as the product cache manager.
JCS is an open source project of Apache, project URL: http://jakarta.apache.org/jcs/

(1)The cacheaccess class annotation is written to this class provides an interface for all types of access to the cache. This class provides the operation interface for caching. This class contains two members:

Note: JCs
The JCs object is cached to disk and written only when the cache partition performs the dispose () operation or JVM shutdown, rather than saving one write;
If the JCS object is cached on the disk, it may fail to be cached on the disk due to exceptions such as power failure;

JCS is an implementation of cache in Java. It supports caching data to the memory or hard disk and setting the effective duration of the cache object. The following JAR packages are required for use:
