Spring MVC latest, html response is getting downloaded instead of displaying

I have very simple spring mvc web app, running in wildfly 8.2.0 server. Configured fully with spring annotation config including WebApplicationInitializer (no web.xml). Controller is getting invoked but my results page is getting downloaded instead of displaying. given below is my config and controller code Config Code

@Configuration 
@EnableWebMvc
@ComponentScan(basePackages = { "com.sample.web.controllers" })
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

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

    @Bean(name = "multipartResolver")
    public CommonsMultipartResolver getMultipartResolver() {
        return new CommonsMultipartResolver();
    }
}

Controller code is

@Controller
public class HomeController {

    @RequestMapping(value="/hello",method=RequestMethod.GET)
    public String sayHello(){
        return "hello";
    }
}

My hello.jsp is inside WEB-INF/views/hello.jsp

Any idea? why the result html is getting downloaded instead of displaying in browser ? Its downloaded as application/octet-stream with out any file extension, the content of the file is my jsp's html

As an update if i dont use WebApplicationInitializer and instead if i use web.xml with the following minimum content

<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>org.egov</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>
Solution

  • As answered on SPR-12558, the servlet mapping should be set to /, not /* in the ServletInitializer Java class (like in the web.xml).
