a simple way of doing that.

== Error Handling
Spring Boot Actuator provides an `/error` mapping by default that handles all errors in a
sensible way, and it is registered as a ``global'' error page in the servlet container.
For machine clients it will produce a JSON response with details of the error, the HTTP
status and the exception message. For browser clients there is a ``whitelabel'' error
view that renders the same data in HTML format (to customize it just add a `View` that
resolves to ``error'').
If you want more specific error pages for some conditions, the embedded servlet containers
support a uniform Java DSL for customizing the error handling. For example:
[source,java,indent=0,subs="verbatim,quotes,attributes"]
----
@Bean
public EmbeddedServletContainerCustomizer containerCustomizer(){
return new MyCustomizer();
}
// ...
private static class MyCustomizer implements EmbeddedServletContainerCustomizer {
@Override
public void customize(ConfigurableEmbeddedServletContainer factory) {
factory.addErrorPages(new ErrorPage(HttpStatus.BAD_REQUEST, "/400"));
}
}

You can also use regular Spring MVC features like http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#mvc-exception-handlers[`@ExceptionHandler`
methods] and http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#mvc-ann-controller-advice[`@ControllerAdvice`].
