Spring boot standalone tomcat HttpServletResponse 总是返回状态 200

Question

我正在使用 spring boot 版本 1.1.8 ，我有以下拦截器拦截所有传入的 http 请求，一个功能是在 post 句柄上打印响应状态代码

public class TimingInterceptor extends HandlerInterceptorAdapter {
private static final String TIME_ATTR = "startTime";

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
        Object handler) throws Exception {
    request.setAttribute(TIME_ATTR, System.currentTimeMillis());
    boolean hasQuery = StringUtils.isNotEmpty(request.getQueryString());
    log.info("[START] method={} path={} {}{}", request.getMethod(), request.getRequestURI(),
            hasQuery ? "?" : "", hasQuery ? request.getQueryString() : "");
    return super.preHandle(request, response, handler);

}

@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response,
        Object handler, ModelAndView modelAndView) throws Exception {
    try {
        long duration = System.currentTimeMillis() - (long) request.getAttribute(TIME_ATTR);

        log.info("[FINISH] method={} path={} status={}  [time={}] Milisec",
                request.getMethod(), request.getRequestURI(), response.getStatus(), duration);
    } catch (Exception e) {
        log.error("Error while measuring timing", e);
    }
    super.postHandle(request, response, handler, modelAndView);
}

在嵌入式 tomcat 上运行时，状态符合预期，例如在这种情况下:

@RequestMapping(method = RequestMethod.GET, value = "/test")
public ResponseEntity<Void> test(HttpServletResponse response) {
    return new ResponseEntity<Void>(HttpStatus.CREATED);
}

拦截器将打印 201，这是 (CREATED) 但是当在独立的 tomcat 上运行时，拦截器将打印 200 也尝试过这种方式

@RequestMapping(method = RequestMethod.GET, value = "/test")
public ResponseEntity<Void> test(HttpServletResponse response) {
    response.setStatus(201);
    return new ResponseEntity<Void>(HttpStatus.CREATED);
}

但是没有成功，有什么想法是错的吗？将不胜感激!

这是来自 Spring Boot 的 ErrorPageFilter 包装了 HttpServletResponse。可能是一个错误。
