jsp servlet 如何快速生成动态页面？求简单方法！
我知道两种方法：
1.在servlet中写入很多的html标签
2.在jsp页面中用很多的java代码
请问有没有更加方便的方法来实现动态页面的编写！？？？？？？？？？？？？？？ java jsp servlet html web
[解决办法]
用struts2之类的框架，你会发现你的1、2两种方法中的弊端都可以适当避免。
[解决办法]
建议使用mvc框架：struts2,spring-mvc。试图层用：velocity

前台可以JS动态显示数据
[解决办法]
最快的方法就是jsp，所有代码都写在jsp中，前台，服务器端代码。这是最快也是最不好的一种方法。既然要快，就这样做吧。

iframe试试

我之前做的静态化原理是，get获得url页面数据，输出为html。
[解决办法]
ajax,前台都不用jsp,html就好了
