文档介绍：在 Spring MVC 中, jsp 文件中尽量不要有 Java 代码, 只有 HTML 代码和"迭代(forEach)"与"判断(if)"两个jstl标签. jsp 文件只作为渲染(或称为视图 View)模板使用.
好了, 我们开始吧. 首先我们需要一个放在 WEB-INF 目录下的 文件:
:
1 <?xml version="" encoding="UTF-8"?>
2
3 <web-app version="" xmlns="http://java./xml/ns/j2ee"
4 xmlns:xsi="1/XMLSchema-instance"
5 xsi:schemaLocation="http://java./xml/ns/j2ee
6 http://java./xml/ns/j2ee/web-">

8 <context-param>
9 <param-name>contextConfigLocation</param-name>
10 <param-value>
11 /WEB-INF/
12 /WEB-INF/
