这个工具的功能说出来让人大跌眼镜，它让JSP当成脚本来执行，就像执行php脚本一样来执行JSP页面，这样做有什么意义呢？有两个：1,它以较少的性能下降换来发快速的部署，对于经常修改的页面，这样或许更快。2,在我们开发时是不太在意性能的，反而经常调试程序，反复部署很浪费时间，有了这个工具JSP则不需部署。-The function of this tool surprise people say, it allows scr ipts to run as a JSP, just as the implementation of the same php scr ipt to run JSP pages, so what implications does it have? There are two: 1, its performance with less fat in exchange for rapid deployment of changes to the regular page, which might more quickly. 2, in our development is not about performance, but regular testing procedures, repeated deployment is a waste of time, with this tool you do not need to deploy JSP.
