Question

我在创建示例应用程序时是初次使用spring mvc我在web.xml文件中有错误。

这是我的网络应用标签：

<web-app id="WebApp_ID" version="2.4" 
    xmlns="http://java.sun.com/xml/ns``/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

我收到错误：

在此行找到多个注释：

- Attribute "version" must be declared for element type "web-app".
- Attribute "xsi:schemaLocation" must be declared for element type "web-app".
- The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-
 param*,filter*,filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-
 page*,taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)".
- Attribute "xmlns" must be declared for element type "web-app".

您的web.xml包含不必要的字符：的＆＃34;``＆＃34;

正确地使用web.xml：

<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

在web.xml文件中的此行找到多个注释
