Maven Spring Web MVC資源不可用

-1

使用Maven創建Spring MVC Web應用程序。請找到以下目錄結構的圖像。 web.xml，dispatcher-servlet.xml文件。我無法獲得所需的index.jsp頁面內容。我對此很陌生，請任何人都可以檢查並讓我知道錯誤在哪裏？Maven Spring Web MVC資源不可用

Web.xml中：

<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_2_5.xsd" 
     version="2.5"> 
    <display-name>MongoSample</display-name> 
    <welcome-file-list> 
      <welcome-file>/jsp/index.jsp</welcome-file> 
    </welcome-file-list> 
    <servlet> 
     <servlet-name>dispatcher</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>dispatcher</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 

    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/dispatcher-servlet.xml</param-value> 
    </context-param> 

    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 
</web-app>

調度-servlet.xml中：

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

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

是JSP文件夾內的index.jsp存在？ –

@NallaSrinivas是的。 – Harshit

在SpringMVC應用程序中，通常使用控制器（具有@Controller註釋的Java類）來處理請求並命名應執行html呈現的jsp。你有沒有這樣一個控制器，如果你沒有，那麼請張貼它（特別是返回的視圖名稱和控制器映射到的url）以及你請求的url與你的問題相關。 – Ralph

在春天，你需要一個控制器（方法）來渲染JSP，這可能是一個正常的「手」寫控制器，或者一些服用點這樣的

<view-controller path="index.html*" view-name="index"/>

謝謝你，爲了你的回答，我找到了問題，我解決了這個問題，但現在我得到了一些例外。將嘗試解決相同的問題。 – Harshit

@哈爾吉特：請不要改變問題的範圍，而應提出一個新的問題。 – Ralph
