.html文件 <welcome-file> 加载.jsp文件时引发404错误

Question

My web.xml file

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>Go Scrapper</display-name>

  <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-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>

  <welcome-file-list>
    <welcome-file>new.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>

</web-app>

I only use any one of the following when i run the program, when i use new.jsp, i get a page, but when i use index.html i get an error 404, both are in the same directory, (ie) under WebContent/.

I have entered both here for ur understanding

My dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

hey guys, When the welcome file is a jsp then it loads the page, If i change it to a html, it hits me with a 404 error. I have checked with other codes. everything seems to be correct. I cant quite get what i have done wrong here.

Answer 1

    i have tried following way and it's work.

    Spring config:

    <resources mapping="/static/**" location="/WEB-INF/static/" />

<beans:bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
     <beans:property name="prefix" value="" />
<beans:property name="suffix" value=".html" />
    </beans:bean>



    Controller method:

    @RequestMapping(value = "/", method = RequestMethod.GET)
      public String homePage(ModelMap model, HttpServletRequest servletRequest, HttpServletResponse response) {
        String returnText = "static/html/index";
        return returnText;
    }
