[Last Updated: May 18, 2020]

Example

Java Config

@EnableWebMvc
@Configuration
public class MyWebConfig {

  @Bean
  public ExampleController exampleController() {
      return new ExampleController();
  }

  @Bean
  public WebMvcConfigurer staticPageConfigurer() {
      return new WebMvcConfigurer() {
          @Override
          public void addResourceHandlers(ResourceHandlerRegistry registry) {
              registry.addResourceHandler("/static/**")
                      .addResourceLocations("/static/");
          }
      };
  }
}
public class MyWebInitializer implements WebApplicationInitializer {

  @Override
  public void onStartup (ServletContext servletContext) {
      AnnotationConfigWebApplicationContext ctx =
                new AnnotationConfigWebApplicationContext();
      ctx.register(MyWebConfig.class);
      ctx.setServletContext(servletContext);

      ServletRegistration.Dynamic servlet =
                servletContext.addServlet("springDispatcherServlet",
                                          new DispatcherServlet(ctx));

      servlet.setLoadOnStartup(1);
      servlet.addMapping("/");
  }
}

A static html with Form post submission

<html>
<body>
<h2>Person Details</h2>
<form action="/example-handler" method="post">
    <label for="personName">Name:</label><br>

    <input type="text" id="personAddress" name="personAddress"><br><br>
    <input type="submit" value="Submit">
</form>

</body>
</html>

Spring MVC controller
