Spring MVC 4 与 HTML 页面而不是 JSP

Question

I am using Spring MVC 4 to build a web app, when I run the application the default home page is index.jsp, I want to change it to index.html.

I have tried a lot of solutions, and no one is worked for me.

web.xml:

    <?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <display-name>TEST</display-name>
    <context-param>
        <param-name>contextClass</param-name>
        <param-value>
            org.springframework.web.context.support.AnnotationConfigWebApplicationContext
        </param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>SpringDispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextClass</param-name>
            <param-value>
                org.springframework.web.context.support.AnnotationConfigWebApplicationContext
            </param-value>
        </init-param>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>es.test.test</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringDispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <session-config>
        <session-timeout>30</session-timeout>
    </session-config>
</web-app>

MvcConfiguration.java

@Configuration
@ComponentScan(basePackages = "com.test.test")
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter {

    @Bean
    public ViewResolver getViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/assets/**").addResourceLocations("/assets/");
    }
}

IndexController.java

@RestController
public class IndexController {

    @GetMapping(value = "/")
    public ModelAndView test(HttpServletResponse response) throws IOException {
        return new ModelAndView("index");
    }

}

I have changed the suffix to.html and it is not working, also the from web.xml and still have the same problem.

Add in your web.xml follow code

<servlet> 
     <servlet-name>htmlServlet</servlet-name> 
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class> 
        <load-on-startup>2</load-on-startup> 
 </servlet> 
 <servlet-mapping> 
        <servlet-name>htmlServlet</servlet-name> 
        <url-pattern>*.html</url-pattern>
 </servlet-mapping>

and modify

resolver.setSuffix(".jsp");

to

to  resolver.setSuffix(".html");

in your MvcConfiguration.java

if not working

modify controller like this

@GetMapping(value = "/")
public String test(HttpServletResponse response) throws IOException {
    return "index";
}
