springBoot集成zuul路由forward,设置setSendZuulResponse无效

正确书写方式如下:

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

书写过程中遇到了阻塞特此记录.

springBoot集成的route拦截器包含下面三种.

一.zuul的SimpleHostRoutingFilter主要用来转发不走eureka的proxy

通过设置 ctx.setSendZuulResponse(false);使不进行路由

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

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

二.zuul的SendForwardFilter处理路由规则中forward的本地跳转

通过设置  ctx.set("sendForwardFilter.ran", true);使不进行路由

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处理路由

通过设置 ctx.setSendZuulResponse(false);使不进行路由

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();
    }
