Question

高手进，web.xml为什么找不到默认首页?

web.xml，结合了spring，表示层用的velocity，配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<url-pattern>*.htm</url-pattern>
</servlet-mapping>

<welcome-file-list>
<welcome-file>index.htm</welcome-file>
</welcome-file-list>
<!-- 配置DWR -->
<servlet>

</init-param>
<!-- By default DWR creates application scope objects when they are first
used. This creates them when the app-server is started -->
<init-param>
<param-name>
initApplicationScopeCreatorsAtStartup
</param-name>
<param-value>true</param-value>
</init-param>

<!-- This enables full streaming mode. It's probably better to leave this

<servlet-mapping>

</web-app>
为什么找不到默认首页？，我直接输入http://192.168.1.102:8080/laifw/index.htm是可以打开的，如果是http://192.168.1.102:8080/laifw/就会报404错误
用的tomcat服务器

Answer 2

在<web-app> 内加入下面配置 :

<welcome-file-list>
<welcome-file>index.htm</welcome-file>
</welcome-file-list>

加到最后面

Answer 3

虚拟路径没有配置对
在tomcat的local文件夹理.xml文件配置虚拟路径

Answer 4

打开IIS->默认网站->属性->文档->启用默认文档->添加->输入index.htm->确定

Answer 5

照理说你配置的是正确的，就不知道你的http://192.168.1.102:8080/laifw/index.htm是不真的能访问到了
