springBoot集成zuul路由forward,設置setSendZuulResponse無效

正確書寫方式如下:

RequestContext ctx = RequestContext.getCurrentContext();
ctx.setSendZuulResponse(false);
ctx.set("sendForwardFilter.ran", true);
ctx.setResponseBody("返回信息");
return null;

書寫過程中遇到了阻塞特此記錄.

springBoot集成的route攔截器包含下面三種.

一.zuul的SimpleHostRoutingFilter主要用來轉發不走eureka的proxy

通過設置 ctx.setSendZuulResponse(false);使不進行路由

org.springframework.cloud.netflix.zuul.filters.route.SimpleHostRoutingFilter#shouldFilter

    public boolean shouldFilter() {
        return RequestContext.getCurrentContext().getRouteHost() != null && RequestContext.getCurrentContext().sendZuulResponse();
    }

二.zuul的SendForwardFilter處理路由規則中forward的本地跳轉

通過設置  ctx.set("sendForwardFilter.ran", true);使不進行路由

org.springframework.cloud.netflix.zuul.filters.route.SendForwardFilter#shouldFilter

    public boolean shouldFilter() {
        RequestContext ctx = RequestContext.getCurrentContext();
        return ctx.containsKey("forward.to") && !ctx.getBoolean("sendForwardFilter.ran", false);
    }

 

三.zuul的RibbonRoutingFilter處理路由

通過設置 ctx.setSendZuulResponse(false);使不進行路由

org.springframework.cloud.netflix.zuul.filters.route.RibbonRoutingFilter#shouldFilter

    public boolean shouldFilter() {
        RequestContext ctx = RequestContext.getCurrentContext();
        return ctx.getRouteHost() == null && ctx.get("serviceId") != null && ctx.sendZuulResponse();
    }
