spring入门(八) spring mvc设置默认首页

1.web.xml配置如下

 1 <!DOCTYPE web-app PUBLIC
 2         "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 3         "http://java.sun.com/dtd/web-app_2_3.dtd" >
 4 
 5 <web-app version="2.4"
 6          xmlns="http://java.sun.com/xml/ns/j2ee"
 7          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 8          xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
 9         http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
10     <display-name>www.xrelz.com</display-name>
11 
12     <!--解决中文乱码的问题-->
13     <filter>
14         <filter-name>encodingFilter</filter-name>
15         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
16         <init-param>
17             <param-name>encoding</param-name>
18             <param-value>UTF-8</param-value>
19         </init-param>
20         <init-param>
21             <param-name>forceEncoding</param-name>
22             <param-value>true</param-value>
23         </init-param>
24     </filter>
25     <filter-mapping>
26         <filter-name>encodingFilter</filter-name>
27         <url-pattern>/*</url-pattern>
28     </filter-mapping>
29 
30     <!--configure the setting of springmvcDispatcherServlet and configure the mapping-->
31     <servlet>
32         <servlet-name>springmvc</servlet-name>
33         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
34         <init-param>
35             <param-name>contextConfigLocation</param-name>
36             <param-value>classpath:springmvc-config.xml</param-value>
37         </init-param>
38         <!-- <load-on-startup>1</load-on-startup> -->
39     </servlet>
40 
41     <servlet-mapping>
42         <servlet-name>springmvc</servlet-name>
43         <url-pattern>/</url-pattern>
44     </servlet-mapping>
45     <servlet-mapping>
46         <servlet-name>springmvc</servlet-name>
47         <url-pattern>/index</url-pattern>
48     </servlet-mapping>
49 
50     <welcome-file-list>
51         <welcome-file>index</welcome-file>
52     </welcome-file-list>
53 </web-app>

关键是41-52行

2.控制器controller

要有对应的 @RequestMapping("/index") 即可.

3.如何直接通过域名访问

如果要发布到服务器,不带项目名访问,把项目打包成ROOT.war,放到webapps下即可. ROOT里面直接是资源文件和WEB-INF(不带项目文件夹).
