Jac*_*ack 6 java spring spring-mvc tiles-3
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).
静态页面的示例是index.jsp和aboutus.jsp.如何访问这些静态页面？我应该通过控制器吗？
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？本教程建议使用单独的控制器,但我不确定这是否是最佳解决方案.因为它向服务器发送不必要的请求.
如果有比Tiles更好的选择,请告诉我

调节器
@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"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %>

的index.jsp
<p>
This is the body of index page
</p>
使用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.
我刚刚找到了一个很好的解决方案，为了处理我们可以<mvc:view-controller>在 servlet 中使用的静态页面，示例代码在这里和这里，它也可以与 Tiles 一起使用，只需确保文件definition中的每个路径都有一个tiles.xml。
<mvc:view-controller path="/index" />
<mvc:view-controller path="/" view-name="index"/>
