HTTP Status 404 - Spring MVC

Question

I just created a sample spring mvc project in spring tool suit (without any modification) and when i am executing it i am getting the output as per index.jsp. But after that i just add one index.html page in view folder and i made following two changes

In controller class i added : return 'index';

 <beans:property name="prefix" value="/WEB-INF/views/" />
 <beans:property name="suffix" value=".html" />

while executing the code after change on Pivotal Server Developer Edition v3.1 i am getting HTTP Status 404 (The requested resource is not available error.)

And as per my knowledge there is no other change required. Please provide some suggestion. Thanks in advance

HomeController.java

@Controller

public class HomeController {

private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

/**
 * Simply selects the home view to render by returning its name.
 */
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
    logger.info("Welcome home! The client locale is {}.", locale);

    Date date = new Date();
    DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);

    String formattedDate = dateFormat.format(date);

    model.addAttribute("serverTime", formattedDate );

    return "index";
}

}

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

Do you have your controller class annotated with @Contoller? Do you see your controller class being registered in the logs at start up? You should post your application configuration file, your full Contoller and your web.xml — mad_fox, Nov 26 '15 at 20:48
Do you have any welcome-file-list tag defined in your root-context.xml? Also do you have index.html file at /WEB-INF/views/ location? — Abhash Upadhyaya, Nov 27 '15 at 04:32
And what about this part: ``? You are dealing with JSP files as seen on screenshot and suffix is html? — Branislav Lazic, Nov 27 '15 at 07:22
What is the url you are trying to test and do you have index.html in your '/WEB-INF/views/ folder?' — Omkar Puttagunta, Nov 27 '15 at 09:56

Did you config viewResolver

<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/pages/"/>
    <property name="suffix" value=".jsp"/>
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
</bean>

@AbhashUpadhyaya It's configured. But incorrectly since suffix in his definition is `.html`. It should be `.jsp`. – Branislav Lazic Nov 27 '15 at 07:27

Since .html files are static and do not require processing by a servlet then it is more efficient, and simpler, to use an <mvc:resources/> mapping. This requires Spring 3.0.4+.

For example:

<mvc:resources mapping="/static/**" location="/static/" />

which would pass through all requests starting with /static/ to the webapp/static/ directory.

So by putting index.html in webapp/static/ and using return "static/index.html"; from your method, Spring should find the view.

IN web.xml change url pattern from

<url-pattern>/</url-pattern>

to

<url-pattern>/*.html</url-pattern>
