JSP是用来做web服务开发的语言运行于tomcat类web服务器，较之于servlet这种纯java的服务脚本而言更容易编辑和修改，因为静态部分和动态部分使用标记< >和标签<jsp:等符号强制分开，使得程序员编辑时一目了然，需要强调的是使用标记分开静态（被控制）动态脚本（控制）部分使得人更容易理解的技术被称之为模板引擎技术。freemarker是一个优秀的模板引擎，既可以作为web服务器编辑，又可以生成本地文件实现代码的生成，关于代码生成器采用模板引擎这是做生成器的都懂的技术。我贡献的这个技术很简单，就是将JSP也用来生成本地文件，JSP生成XML,JAVA,TXT等一系列文本的东西。-JSP is used for web services development language classes run on tomcat web server, compared to this pure java servlet service scr ipt easier to edit and modify the terms, because the static and dynamic parts using tags <　> and tags <jsp: symbols forced apart, so that the programmer edit a glance, be emphasized that the use of tags separate static (controlled) dynamic scenario (control) section makes people easier to understand technology is called template engine technology. freemarker is an excellent template engine, either as a web server editor, and can generate a local file to achieve code generation, code generator on the use of a template engine which is doing everything generator technology. My contribution to this technique is very simple JSP will also be used to generate a local file, JSP generate things XML, JAVA, TXT and a series of text.
