如何处理Spring MVC中静态页面的寻址 [英] How to handle addressing to static pages in Spring MVC
问题描述
我有一个使用Tile3的Spring MVC应用程序。我有很多静态页面需要将它们嵌入到tile3当前提供的网站模板中。 （我需要在所有页面上使用相同的页脚和页眉，无论是动态还是静态，但不确定如何对静态页面进行寻址）。
I have a Spring MVC application that is using Tile3. I have many static pages that need to embed them in the template of the website that is currently provided by tile3. (I need to have the same footer and header on all pages, either dynamic or static but not sure how to do the addressing for static pages).
静态页面的示例是index.jsp和aboutus.jsp。如何访问这些静态页面？我应该通过控制器来做吗？
Examples of static pages are index.jsp and aboutus.jsp. How can I access these static pages? should I do it through a controller?
我知道我可以使用jsp：include但这是一个好习惯吗？因为我正在使用瓷砖，所以没有其他选择吗？这个教程建议有单独的控制器，但我我不确定这是否是最佳解决方案。因为它向服务器发送了不必要的请求。
I know I can use jsp:include but is that a good practice? isn't there any alternative as I am using tiles? This tutorial suggested to have separate controllers but I am not sure if that would be an optimal solution. As it sends unnecessary requests to the server.
请告诉我是否有比Tiles更好的选择

控制器
@Controller
public class HelloController {
protected final Log logger = LogFactory.getLog(getClass());
public HelloController() {
System.err.println("Constructor of HelloController");
}
@RequestMapping("/index.htm")
public String index(){
System.err.println("in index method");
return "index";
}
baseLayout.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"

index.jsp
<p>
This is the body of index page

使用JSP：include
Using JSP:include
pros
- No extra load neither on DB nor on server
cons
- To backup need to backup all static files
- Might have overwork as each page should be prepared separately rather than having a single template for all pages and just populate the template
- If need to add something to static pages need to change all pages.
推荐答案
我刚刚找到了一个很好的解决方案，处理静态页面我们可以在servlet中使用< mvc：view-controller> ，示例代码是这里和，它也适用于Tiles，确保你有一个定义对于 tiles.xml 文件中的每个路径。
I just have found a great solution for it, to handle static pages we can use <mvc:view-controller> in servlet, sample code is here and here, it works with Tiles as well just make sure you have a definition for each path in your tiles.xml file.
<mvc:view-controller path="/index" />
<mvc:view-controller path="/" view-name="index"/>
