在DispatcherServlet中使用URI [/ TestSpring /]發現名爲'dispatcher'的HTTP請求未找到映射

Question

請問我需要您的幫助來運行Spring應用程序，我是Spring的新手，我一直有問題需要運行它。我使用NetBeans創建了項目，並創建了所有默認文件，但代碼未運行。請幫忙，因爲我已經尋找解決方案，但都沒有幫助。由於

的web.xml

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

    </listener>

    <welcome-file-list> 
     <welcome-file>redirect.jsp</welcome-file> 
    </welcome-file-list> 
</web-app> 

調度-servlet.xml中

<?xml version="1.0" encoding="UTF-8"?> 
<beans:beans xmlns="http://www.springframework.org/schema/mvc" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    http://www.springframework.org/schema/beans/spring-beans.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context.xsd"> 

    <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure --> 

    <!-- Enables the Spring MVC @Controller programming model --> 
    <annotation-driven /> 

    <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory --> 
    <resources mapping="/resources/**" location="/resources/" /> 

    <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory --> 
    <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <beans:property name="prefix" value="/WEB-INF/views/" /> 
     <beans:property name="suffix" value=".jsp" /> 
    </beans:bean> 
</beans:beans> 

的applicationContext.xml

<?xml version='1.0' encoding='UTF-8' ?> 
<!-- was: <?xml version="1.0" encoding="UTF-8"?> -->

    public ModelAndView IndexView() 
    { 
     ModelAndView mv = new ModelAndView("index"); 
     return mv; 
    } 
} 

redirect.jsp中

<%-- 
Views should be stored under the WEB-INF folder so that 
they are not accessible except through controller process. 

This JSP is here to provide a redirect to the dispatcher 
servlet but should be the only JSP outside of WEB-INF. 
--%> 
<%@page contentType="text/html" pageEncoding="UTF-8"%> 
<% response.sendRedirect("index.jsp"); %> 

Answer 1

你是如何運行應用程序？

你的問題的標題，你所提供的對應來看，您的網址應該是/index沒有/TestSpring

Answer 2

我也有類似的問題。檢查你的war文件是否被創建（如果你正在使用maven，則在目標文件夾中）。然後將war文件部署到tomcat並嘗試訪問它。在您的IDE中，您也可以嘗試停止服務器，然後單擊* .war文件並嘗試運行它。

雖然我使用的註釋與xml配置對比。
