每个路径一个Servlet或在一个Servlet中处理多个路径? [英] One Servlet per path or handle multiple paths in a Servlet?

问题描述

我想知道处理网站中的多个页面时处理servlet的最佳实践是什么. Servlet中的大多数GET请求都只是返回一个新的jsp页面.我想到了两种方法:

I'm wondering what is the best practice in handeling servlets when dealing with a many pages in a website. Most GET requests in servlets simply return a new jsp page. I had thought of two approaches:

• 为网站中的每个路径分配一个servlet，例如主页的homeservlet，注册页面的注册servlet，登录页面的登录servlet等.

• Assign a servlet for each path in the webiste e.g a homeservlet for home page, registerservlet for registration page, loginservlet for login page etc.

具有少量servlet，它们可以处理多个路径并相应地处理它们，例如一个UserServlet，可以完成用户的注册和登录工作.但是我认为这种方法可能只会导致很多if语句，并且可能很难管理.理想的是在servlet中为每个路径分配一个方法(类似于Laravel的方法)

Have a small number of servlets that process multiple paths and handle them accordingly e.g. A UserServlet that could do the job of registration and logging in users. However I thought this approach might would just lead to lots of if statements and may be quite unmanageable. What would be ideal is assigning a method in a servlet to each path (similar to how Laravel does it)

推荐答案

通常情况下，最佳解决方案取决于上下文和必须提供的功能. 我认为在大多数情况下，允许从单个servlet处理多个路径将更为有效，因为它只允许针对多个情况开发一个servlet. 在以下情况下，最好将一组路径映射到单个servlet:

As it is often the case, what is best depends on the context and the functionality that must be offered. I would assume that in most cases allowing multiple paths to be handled from a single servlet would be more efficient as it allows the development of only one servlet for multiple cases. Mapping a group of paths to a single servlet would be preferable in the following cases:

1. 这组路径提供的功能是相似的"，可以由单个servlet处理，也许可以考虑实际路径.
2. 应该提供的功能与用于调用servlet的实际路径无关.

不过，为每个servlet分配一个路径可能是有益的:

However it could be the cases that assigning a single path per servlet would be beneficial:

1. servlet的功能应仅通过单个路径提供.
2. 不同路径的功能不同，足以要求使用不同的Servlet类来实现它们.
