两种技术可以激烈竞争,也可以紧密合作。从客户的角度来说,技术之间的融合非常重要,因为一个庞大的应用系统,通常不可能由单一语言/和技术独立完成。PHP/Java Bridge的出现就将成为PHP和Java间的一道桥梁,为需要结合PHP与Java的企业提供一个良好的选择。

(一)什么是JSR,什么是JSR223 ?
JSR(Java 规范请求)是指向JCP(Java Community Process)提出新增一个标准化技术规范的正式请求。任何人都可以提交JSR(Java 规范请求),以向Java平台增添新的API和服务。JSR已成为Java界的一个重要标准。
在Java Servlet规范(Servlet 2.4,JSR-154)中,定义了一系列核心的抽象概念(WEB程序处理过程中需要考虑的各种对象)来让Java程序员编写WEB程序,包括session,request,response等等。当程序员在编写程序的时候,可以很方便安全地与这些对象进行通讯。JSR223描述的是这些Java对象如何向用其它脚本语言编写的WEB页面开放,使其它语言也可以访问这些对象。当前这个规范将被用于PHP,不过这种概念是独立于脚本语言的,也就是说在将来可能被应用于PHP之外的其它脚本语言。一句话,JSR223的目的是将脚本语言集成到Java平台之上。
(二) 什么是PHP/Java Bridge ?
PHP/Java Bridge包含一个PHP模块(包括java.so,php_java.dll)和一个相关的后端程序(JavaBridge.jar,JavaBridge.war或MonoBridge.exe),用于连接PHP的对象体系到Java或ECMA 335(CLI, Microsoft .NET Framework的重要子集)虚拟机。 它完全实现了JSR 223规范请求,可以使PHP脚本访问基于CLR(如VB.NET,C#)或Java(Java,KAWA,JRuby)的应用程序。PHP/Java Bridge通过本地socket用一个高效的通讯协议与虚拟机进行通讯。一个多进程的">javax.script包。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
