Spring MVC working with .html

Question

I'm just starting with Spring MVC. Created a default template with IntelliJ, and now I'm trying to add some content.

The default extension for the pages is .jsp , but I want to change my pages to .html extension and can't figure out how.

So I have about.jsp file and I want to change it to about.html . I changed the filename itself and in the file mvc-dispatcher-servlet.xml I changed:

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

To:

<property name="suffix" value=".html"/>

After my change I get:

05-Jul-2016 15:31:25.788 WARNING [http-nio-8082-exec-1] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/WEB-INF/view/pages/about.html] in DispatcherServlet with name 'mvc-dispatcher'

And a page with 404 status.

This my directory tree:

mvc-dispatcher-servlet.xml :

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/view/pages/"/>
    <property name="suffix" value=".html"/>
</bean>

web.xml :

<web-app version="2.4"

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

HelloController.java :

package com.weitz.alex;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/")
public class HelloController {
    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {
        model.addAttribute("message", "Hello world!");
        return "about";
    }
}

Answer 1

remove this line <property name="suffix" value=".html"/> since html pages are static handle it as a resource add these lines to the configuration .

<mvc:resources mapping="/pages/**" location="/WEB-INF/view/pages/" />
<mvc:annotation-driven/>

there is no need to handle this with a viewresolver .

and change your return statement in the controller to this.

return "redirect:/pages/about.htm";

Answer 2

It looks to me like you're missing a resource mapping for your .html pages . Try adding one to your mvc-dispatcher-servlet.xml . An example could look like this:

<mvc:resources mapping="/pages/**" location="/WEB-INF/view/pages/" />

For a more detailed description of your problem, you might also have a look at this answer, which shows the solution for a very similar problem.

I'd also recommend you to change your folder structure and place your files in a folder called "/static/resources/" or similar because your .html files are static (your jsp files weren't).

Your prefix and suffix properties look like they should just work fine.
