Question

我正在使用Maven项目开发Spring，我已经将所有依赖项放入pom.xml文件中，如下所示，

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </dependency>
  </dependencies>
</project>

我在JSP页面中使用了表单标签，我的Jsp页面如下所示：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>LogIn Page</title>
</head>
<body>
    <h2>LogIn Page</h2>
     <form:form id="loginForm" modelAttribute="login" action="loginProcess" method="post">
     <table align="center">
         <tr>
             <td>
                 <form:label path="username">Username: </form:label>
             </td>
             <td>
                 <form:input path="username" name="username" id="username" />
             </td>
         </tr>
         <tr>
             <td>
                 <form:label path="password">Password:</form:label>
             </td>
             <td>
                 <form:password path="password" name="password" id="password" />
             </td>
         </tr>
         <tr>
             <td></td>
             <td align="left">
                 <form:button id="login" name="login">Login</form:button>
             </td>
         </tr>
         <tr></tr>
         <tr>
             <td></td>
             <td><a href="home.jsp">Home</a>
             </td>
         </tr>
     </table>
 </form:form>
 <table align="center">
     <tr>
         <td style="font-style: italic; color: red;">${message}</td>
     </tr>
 </table>
</body>
</html>

但是，当我尝试运行JSP文件时，出现以下错误：

HTTP Status 500 - The absolute uri: http://www.springframework.org/tags/form cannot be resolved in either web.xml or the jar files deployed with this application

我相信，我已经添加了所有必需的依赖项，但是我找不到问题。

请分享您的想法以寻求解决方案。

先谢谢了。

绝对uri：http://www.springframework.org/tags/form无法在web.xml或与此应用程序一起部署的jar文件中解析
