Question

我正在尝试制作我的第一个spring mvc项目“ hello world”，但它向我显示错误，我看不到页面（我收到404错误）：

类型状态报告

说明原始服务器未找到当前表示   目标资源或不愿意透露其存在。

我尝试了所有我在stackoverflow中进行过大量搜索的内容，但找不到解决方案。

我的代码：

Hellopage.jsp

     <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
        pageEncoding="ISO-8859-1"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="ISO-8859-1">
    <title>Insert title here</title>
    </head>
    <body>

    <h1>Heloo world</h1>
    <h2>hiiiiiiiiiiiiiiiiiii</h2>
    </body>
    </html>

HelloWorld.java

     package firstspringmv;

    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;

    import org.springframework.web.servlet.ModelAndView;
    import org.springframework.web.servlet.mvc.AbstractController;

    public class Helloworld extends AbstractController{

        @Override
        protected ModelAndView handleRequestInternal(HttpServletRequest request,
            HttpServletResponse response) throws Exception {

            ModelAndView model = new ModelAndView("HelloWorldPage");
            model.addObject("msg", "hello world");

            return model;
        }
    }

Web.xml：

        <url-pattern>/</url-pattern>
    </servlet-mapping>
    </web-app>
    </element>

spring-dispatcher-servelt.xml：

    <bean id="viewResolver"

        <property name="prefix">

        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

</beans>
