Spring MVC: How to return custom 404 errorpages?

Question

I\'m looking for a clean way to return customized 404 errorpages in Spring 4 when a requested resource was not found. Queries to different domain types should result in diff

Answer 1

I also needed to NOT use org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer.

According to org.springframework.web.servlet.DispatcherServlet.setThrowExceptionIfNoHandlerFound(boolean): "Note that if DefaultServletHttpRequestHandler is used, then requests will always be forwarded to the default servlet and a NoHandlerFoundException would never be thrown in that case."

https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/servlet/DispatcherServlet.html#setThrowExceptionIfNoHandlerFound-boolean-

Before

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.foo.web")
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {

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

  // ...
}

After

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.foo.web")
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {

  @Override
  public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
  }

  // ...
}
