我们终于完成了这项工作[由我的一位同事编码]：-
public class CustomErrorFilter extends ZuulFilter { private static final Logger LOG = LoggerFactory.getLogger(CustomErrorFilter.class); @Override public String filterType() { return "post"; } @Override public int filterOrder() { return -1; // Needs to run before SendErrorFilter which has filterOrder == 0 } @Override public boolean shouldFilter() { // only forward to errorPath if it hasn't been forwarded to already return RequestContext.getCurrentContext().containsKey("error.status_pre"); } @Override public Object run() { try { RequestContext ctx = RequestContext.getCurrentContext(); Object e = ctx.get("error.exception"); if (e != null && e instanceof ZuulException) { ZuulException zuulException = (ZuulException)e; LOG.error("Zuul failure detected: " + zuulException.getMessage(), zuulException); // Remove error pre to prevent further error handling in follow up filters ctx.remove("error.status_pre"); // Populate context with new response values ctx.setResponseBody(“Overriding Zuul Exception Body”); ctx.getResponse().setContentType("application/json"); ctx.setResponseStatusCode(500); //Can set any error pre as excepted } } catch (Exception ex) { LOG.error("Exception filtering in custom error filter", ex); ReflectionUtils.rethrowRuntimeException(ex); } return null; }}
