About the Key Classes Ehcache consists of a CacheManager, which manages logical data sets represented as Caches. A Cache object contains Elements, which are essentially name-value pairs. You can use Cache objects to hold any kind of data that you wan…

About Write-Through and Write-Behind Caches Write-through caching is a caching pattern where writes to the cache cause writes to an underlying resource. The cache acts as a facade to the underlying resource. With this pattern, it often makes sense to…

About Cache Eviction Algorithms A cache eviction algorithm is a way of deciding which element to evict when the cache is full. In Ehcache , the memory store and the off-heap store might be limited in size. When these stores get full, elements are evi…

Creating a CacheManager All usages of the Ehcache API start with the creation of a CacheManager. The following code snippets illustrate various ways to create one. Singleton versus Instance The following creates a singleton CacheManager using default…

There are several common access patterns when using a cache. Ehcache supports the following patterns: Cache-aside (or direct manipulation) Cache-as-sor (a combination of read-through and write-through or write-behind patterns) Read-through Write-thro…

About Searching The Search API allows you to execute arbitrarily complex queries against caches. The development of alternative indexes on values provides the ability for data to be looked up based on multiple criteria instead of just keys. Note: Ter…

About Explicit Locking Ehcache contains an implementation which provides for explicit locking, using read and write locks. With explicit locking, it is possible to get more control over Ehcache 's locking behavior to allow business logic to apply an…

About Transaction Support Transactions are supported in versions of Ehcache 2.0 and higher. The 2.3.x or lower releases only support XA. However since ehcache 2.4 support for both Global Transactions with xa_strict and xa modes, and Local Transaction…

About Blocking and Self-Populating Caches The net.sf.ehcache.constructs package contains some applied caching classes which use the core classes to solve everyday caching problems. Two of these are BlockingCache and SelfPopulatingCache. Blocking Cach…

About Cache Loaders A CacheLoader is an interface that specifies load() and loadAll() methods with a variety of parameters. CacheLoaders are incorporated into the core Ehcache classes and can be configured in ehcache.xml. CacheLoaders are invoked in…

About Cache Event Listeners Cache listeners allow implementers to register callback methods that will be executed when a cache event occurs. Cache listeners implement the CacheEventListener interface. The events include: An Element has been put An El…

About Exception Handlers By default, most cache operations will propagate a runtime CacheException on failure. An interceptor, using a dynamic proxy, may be configured so that a CacheExceptionHandler can be configured to intercept Exceptions. Errors…

About Cache Decorators Ehcache uses the Ehcache interface, of which Cache is an implementation. It is possible and encouraged to create Ehcache decorators that are backed by a Cache instance, implement Ehcache and provide extra functionality. The Dec…

About CacheManager Event Listeners CacheManager event listeners allow implementers to register callback methods that will be executed when a CacheManager event occurs. CacheManager listeners implement the CacheManagerEventListener interface. The even…

About Cache Extensions Cache extensions are a general-purpose mechanism to allow generic extensions to a cache. Cache extensions are tied into the cache lifecycle. For that reason, this interface has the lifecycle methods. Cache extensions are create…

About Class Loading Class loading, within the plethora of environments that Ehcache can be running, could be complex. But with Ehcache, all class loading is done in a standard way in one utility class: ClassLoaderUtil. Plugin Class Loading Ehcache al…

面向资源的设计 这份设计指南的目标是帮助开发人员设计简单.一致.易用的网络API.同时,它也有助于收敛基于socket的API和(注:原文是with,这里翻译为“和”)基于HTTP的REST API. 以前,人们根据诸如CORBA和Windows COM这样的API接口和方法设计RPC API.随着时间的推移,接口和方法越来越多.最后,接口和方法数不胜数又各不相同.开发人员要正确使用它们,必须仔细了解每一个的用法,这很浪费时间而且容易出错. 2000年,为了与HTTP1.1搭配使用,REST架构…

Flink DataStream API编程指南 Flink中的DataStream程序是对数据流实现转换的常规程序(如过滤.更新状态.定义窗口.聚合).数据流最初是由各种来源(如消息队列.套接字流.文件)创建的.结果通过汇流返回,例如可以将数据写入文件,或标准输出(例如命令行终端).Flink程序可以在各种环境下运行,独立运行,或者嵌入到其他程序中.执行可以发生在本地JVM中,也可以发生在许多机器的集群中. 为了创建你自己的Flink DataStream程序,我们鼓励你从一个Flink程序的…

介绍 Open API即开放API,也称开放平台. 所谓的开放API(OpenAPI)是服务型网站常见的一种应用,网站的服务商将自己的网站服务封装成一系列API(Application Programming Interface,应用编程接口)开放出去,供第三方开发者使用,这种行为就叫做开放网站的API,所开放的API就被称作OpenAPI(开放API). 开放平台分类 根据开放层级划分,开放平台主要分为四层,即“硬件”层.系统层.业务层和应用层. 其中,业务层开放和应用层开放是更加贴近互联网层…
