什么是Model1和Model2?请解释它们各自的特点
就是jsp+javabean和jsp+servlet+javabean两种模式,前者是纯JSP,后者是简单的MVC,
是SUN公司对于MVC模式所先后推出的二种规范,第一种是JSP MODEL1,第二种则是JSP MODEL2.
MODEL1在一定程序上实现了MVC,即JSP是控制层与表示层合二为一了,BEAN则为模式层.这样的效果显然不如将控制层单独划分出来的好.而MODEL2则是将控制层(SERVLET)单独的划分出来了,专门负责业务流程的控制,接受页面的请求,创建所需的JAVABEAN实例,并将处理后的数据再返回给JSP,这样的效果显然要好的多.
简单的说就是耦合度松紧的问题...
除非项目非常简单建议用MODEL2,控制层与表示层混合写起来,很烦的。

Craze for Civil Service ExaminationsLast Saturday was the day for Civil Service Examinations. It was quite an event for the million people who are involved in this year’s competition for a position as a civil servant. Yet we can’t tell whether the day was a beginning or an end for them, because many who fail the exams are very likely to try again and again. This craze has already lasted for at least a decade.It is not without reasons. Very obviously, in many people’s eyes, a job in government brings both money and fame. It provides fairly good pay as well as a high social status. Another advantage should also be counted in: people enjoy stable jobs as being civil servants. Once you are in for it, you are free of worries to be laid off unless you commit very serious mistakes. No wonder so many people strive for it through examinations.I can’t blame people for their pursuit. After all, this is a fierce world filled with all pressures and uncertainties. People have rights to choose an occupation which makes them feel easy. My only wish is that, with such a harsh competition and all levels of severe selection, we can have real qualified people working as our civil servants, serving our people wholeheartedly. (212words)Craze for Civil Service ExaminationsIn recent years, more and more people would like to participate in the test for national civil servants. Many graduates or employees consider the occupation of civil servants as their most ideal choice. They craze for the civil servant test and some of them even put all of their eggs in one basket.This phenomenon has attracted widespread attention.In fact, it’s not difficult to explain such a craze. Above all, nowadays college students face great employment pressure. Civil servant, as one of the most stable professions in China, becomes their preferable selection. Moreover, the welfare and salary of civil servants have been improved greatly, which become a significant advantage enjoyed by many people. Besides, the high social position of civil servants is an important factor drawing many people to compete for this profession.In my opinion, this craze in civil servant test will continue in the following years because the highly competitive situation for employment is uneasy to change. However, with the perfection of employment system and more choices for career, people tend to have an overall understanding on employment. (181words)No one knows the exact origins of the backpacker phenomenon, yet tens of thousands of people have joined in this eco-centric activity. If you want to be a “friend of donkey”, you are not necessarily young or affluent. Many are impoverished students budgeting their travels very carefully; some are middle-aged parents or senior citizens. They go hiking in remote places for months, tour suburban sights on weekends, and are always ready to discover new paths and surprises on their journeys.It’s no easy to trace the exact origin of the backpacker phenomenon in China, yet thousands f people have been attracted to this new, eco-centric style of travelling. To be a friend of donkey, you don’t necessarily have to be young and energetic and rich. Actually many are just impoverished students who have to calculate carefully for each trip; and some others are the middle aged and even senior citizens. Some of them foot to remote places staying there for months, while others may plan excursions during weekends. Basically, they have one thing in common on choosing their routes, that is, to explore the unknown.。
JSP 的model1和model2随着sun公司推出的servlet和JSP技术,为了更好的指导web开发人员进行java WEB的开发,就提出了两种架构模式,即JSP Model1和JSP Model2,那么它们有什么区别呢?JSP Model1模式.它应用了java WEB开发当中的两种技术,一是JSP,二是javabean技术。
其中JSP完成逻辑上的处理和显示,javabean做辅助。
JSP需要完成接受用户的请求,和响应给用户数据,同时还完成流程的控制处理。
而javabean做辅助,如把数据库查询出来的数据做保存,我们就可以通过这个javabean来取得相应数据了。
JSP Model架构图JSP Model的优点:由于它的结构很简单,开发人员很容易上手,适合开发一些小型的java WEB应用。
但有优点就有缺点。
JSP Model1的缺点其实是它的优点所造成的,JSP Model1由于它是把显示代码和逻辑处理代码都放在JSP页面当中,如果开发大型的java WEB应用的话,就显得力不从心了,想想一个大型的java WEB应用里面有多少要显示的代码和多少处理逻辑的代码。
这样一来既不便于开发人员的维护,也不便于美工人员的修改,这些代码那不都成垃圾代码了!那么怎么办呢?基于这种情况,sun公司又推出了一种架构模式,即JSP Model2模式。
如图所示,这个模式是结合了servlet,JSP,javabean的优点推出的一种模式。
这个模式分为三部分 servlet,JSP,javabean。
servlet做的事情是控制到底最后显示哪个JSP页面给用户、JSP做的就是响应用户请求,把结果数据展现给用户、而javabean做的就不单单是对数据库的数据的存取了,这里复杂的业务功能和逻辑处理都交给了它处理。
从它们的设计结构就可以看出JSP Model2的优点。
由于它们在设计上很好的分工,也就是做显示的是JSP,做逻辑处理的是javabean,做控制的是servlet。
