Following example shows how to handle a Post request submitted by a static html page
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
src/main/webapp/static/simple-form.html<html>
<body>
<h2>Person Details</h2>
<form action="/example-handler" method="post">
<label for="personName">Name:</label><br>
