Apache Camel
Apache Camel是Apache基金会下的一个开源项目,它是一个基于规则路由和中介引擎,提供企业集成模式的Java对象的实现,通过应用程序接口(或称为陈述式的Java领域特定语言(DSL))来配置路由和中介的规则。领域特定语言意味着Apache Camel支持你在的集成开发工具中使用平常的,类型安全的,可自动补全的Java代码来编写路由规则,而不需要大量的XML配置文件。同时,也支持在Spring中使用XML配置定义路由和中介规则。
Apache Camel 2.15.5 发布,此版本更新内容如下:
[CAMEL-9161] - Camel spring-boot not finding routes when using spring-cloud
[CAMEL-9202] - Flatpack: Body reader never closed
[CAMEL-9233] - ZipFileDataFormat doesn't take exchange's charset into account
[CAMEL-9236] - Tokenize with regex grouping has a small bug
[CAMEL-9238] - NPE while GenericFile.changeFileName
[CAMEL-9243] - Invocation of Bean fails when Bean extends and abstract which implements the actual method
[CAMEL-9246] - camel-cxf proxy with MTOM does not get attachment back when RPC/literal style WSDL used
[CAMEL-9255] - documentType not used for XPath predicates in XML DSL
[CAMEL-9259] - enableTrace of the Main class doesn't work
[CAMEL-9272] - openweathermap.org requires an APPID id since 09/10/2015
[CAMEL-9276] - Netty4 component allows multiple consumers to bind to the same {host}:{port}
[CAMEL-9311] - Concurrency issue with the dynamic router
[CAMEL-9313] - CamelBlueprintTestSupport - timing problems with property placeholder
[CAMEL-9316] - LevelDBAggregationRepository is logging warnings when exchange is already complete on first aggregation
[CAMEL-9319] - SshClient resource leak when used from ProducerTemplate
[CAMEL-9366] - CXFRS "skipFaultLogging" attribute doesn't work in Spring
[CAMEL-9368] - Netty4 producer hangs when connection is prematurely closed
[CAMEL-9297] - Expose more configuration options from Camel's XStream component
[CAMEL-9309] - camel-jetty - Make it easier to turn on|off java transport over http
[CAMEL-9317] - camel-salesforce's XStream to use a system property to configure its setting
[CAMEL-9335] - camel-netty-http - Suppress Connection reset by peer WARNs
Apache Camel 是一个非常强大的基于规则的路由以及媒介引擎,该引擎提供了一个基于POJO的 企业应用模式(Enterprise Integration Patterns)的实现,你可以采用其异常强大且十分易用的API (可以说是一种Java的领域定义语言 Domain Specific Language)来配置其路由或者中介的规则。 通过这种领域定义语言,你可以在你的IDE中用简单的Java Code就可以写出一个类型安全并具有一定智能的规则描述文件。这与那种复杂的XML配置相比极大简化了规则定义开发。 当然Apache Camel也提供了一个对Spring 配置文件的支持。
Apache Camel 采用URI来描述各种组件,这样你可以很方便地与各种传输或者消息模块进行交互,其中包含的模块有 HTTP, ActiveMQ, JMS, JBI, SCA, MINA or CXF Bus API。 这些模块是采用可插拔的方式进行工作的。Apache Camel的核心十分小巧你可以很容易地将其集成在各种Java应用中。
