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

In later versions of Ehcach-1.6, the UTF8 encoded ehcache.xml configuration file is supported. Because of backwards compatibility, all the ASCII-encoded profiles are completely unnecessary to convert to UTF8.A cache

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.
Caching can be divided into two major categories:
First, through file caching, as the name implies file caching refers to the storage of data on disk, whether you are in XML format, serialized file dat format or other file format;
Second, the memory cache, that

EhCache is a pure Java in-process caching framework, which is fast and capable, and is the default Cacheprovider in Hibernate. Ehcache is a widely used, open source Java distributed cache. Primarily for general purpose caches, Java EE and lightweight containers.

Memcached is a high-performance distributed memory object caching system for dynamic Web applications to mitigate database load. It improves the speed of dynamic, database-driven Web sites by caching data and objects in memory to reduce the number of times a database is read.

Continue to use EhCache and cacheehcache without proper Disk Cache in the net environment
When talking about caching, you may be confused. All types of caching can be analyzed one by one, but finding a suitable Disk Cache under net seems a little difficult.
I. background
This is the case. In a recent project, You need to draw some reports on the web end. Because the basic data sources of reports are in full memory, the memory is relatively tight,
There are several methods for ehcache clusters: RMI, jgroup, and JMS. Here we will talk about the use of ehcache.
The reason why ehcache uses RMI to copy the cache is as follows:
1. Rmi is the default Remote Mechanism of Java.
2. You can optimize TCP options.
3. Because elements must be stored on a disk, it must have been serialized. Therefore, you do not need to

Ehcache is an open-source, standards-based cache that improves performance and reduces database load, and is the most widely used Java-based cache today.
Cache: The wiki defines the cache as "storage of what is going to be used and can be retrieved quickly". A cache is a set of temporary data, either a copy of the data elsewhere, or a result of the calculation. data already in the cache can be repeatedly accessed at minimal cost in term
Ehcache is a distributed cache framework.Distributed cacheWithout the use of distributed caches, cached data is stored separately in each service and is inconvenient for system development. Therefore, the cached data is centrally managed using distributed caching.MyBatis cannot implement distributed caching, and it needs to be integrated with other distributed cache frameworks.Integration Method (Master)MyBatis provides a cache interface, and if you w
