Usage

From source file:org.springframework.boot.autoconfigure.web.BasicErrorController.java

@ExceptionHandler(Exception.class)
public void handle(HttpServletRequest request, HttpServletResponse response, Exception e) throws Exception {
    this.resolver.resolveException(request, response, null, e);

        response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
    }/* ww w .  j  av a2s.  c  o m*/
    // There's only one exception so it's easier for the error controller to identify
    // it this way...
    request.setAttribute(ErrorController.class.getName(), e);
    if (e instanceof BindException) {
        // ... but other error pages might be looking for it here as well
        request.setAttribute(BindingResult.MODEL_KEY_PREFIX + ((BindException) e).getObjectName(), e);
