我选择了一个新创建的 maven webapp 项目，想用它做最简单的 mvc 应用程序。我的环境看起来像这样:

</properties>

我的 applicationContext 非常简单:

<context:component-scan base-package="com.personal.springtest.admin.webapp" />
<mvc:annotation-driven />

web.xml 就这么简单:

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
 version="3.0">
<session-config>
    <session-timeout>
        30
    </session-timeout>
</session-config>

<servlet>
    <servlet-name>iwadminservlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/project-admin-webapp-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

   <servlet-mapping>
    <servlet-name>iwadminservlet</servlet-name>
    <url-pattern>/</url-pattern>
   </servlet-mapping>
</web-app>

我的 Controller 是这样的:

@Controller
public class HomeController {

   @RequestMapping(value="/")
   public String Home(){
    System.out.print("THIS IS a demo mvc, i think i like it");
    // this is temporary, will use viewresolver when everything clears up
    return "/views/home.jsp";
   }

}

我的观点是:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<!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=UTF-8">
      <title>JSP Page</title>
   </head>
   <body>
      <h1>Hello World!</h1>
   </body>
</html>

我得到的错误是

org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

问题 1:我想知道是否是因为我使用的版本，我想我已经阅读了一些关于 tomcat 中支持的版本以及使用的 java ee 版本的内容。不要'真的没有办法解决我的问题。我怎样才能解决这个问题？

问题 2:在出现此错误之前，我的代码是 400，因为我没有将它正确指向 views/home.jsp，但我确实注意到，当我运行netbeans 中的应用程序，它使用 url 打开浏览器:http://localhot:8080/当我期待http://localhost:8080/admin-webapp/ admin-webapp 是我的 war 的名字。我相信这是一个问题，并想解决它。
