NOTE: The demo applications has been revamped and updated (October 2014) to use Spring Boot 1.1.8 and is (hopefully) easier to use and understand.Using HTTP Status Codes Normally any whitelabel error page spring boot unhandled exception thrown when processing a web-request causes the server to return an HTTP 500 response.

When an annotated exception is thrown from a controller method, and not handled elsewhere, it will automatically cause the appropriate HTTP response to be returned with the specified status-code.

This is the code for my CustomErrorHandler bean class and WebInitializer: CustomErrorHandler.java: import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver; public class CustomHandlerExceptionResolver extends DefaultHandlerExceptionResolver { private static final Logger logger = LoggerFactory .getLogger(CustomHandlerExceptionResolver.class); @Override protected ModelAndView doResolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) { try { if (ex instanceof java.lang.Throwable
