Java Golang和apache AB

我有一个带有HTTPPOST请求的系统，它使用Spring5（独立的tomcat）运行。简而言之，它看起来是这样的：

客户端（Apache AB）--->micro服务（java或golang）--->RabbitMQ-->核心（spring+tomcat）

问题是，当我使用Java（Spring）服务时，它还可以。AB显示此输出：

编辑2

func (h *limitHandler) ServeHTTP(w http.ResponseWriter, req *http.Request) {
    select {
    case <-h.connc:


        fmt.Println("ServeHTTP");


        h.handler.ServeHTTP(w, req)

        h.connc <- struct{}{}
    default:
        http.Error(w, "503 too busy", http.StatusServiceUnavailable)
    }
}

---

limitHandler

的定义在哪里？这似乎对这段代码和问题非常关键。可能不相关，但快速查看http部分会发现您在头之前编写响应，这毫无意义，而且您在

计数器上有一个数据竞争

@Adrian-我添加了LimitHandler，但不是全部。如果

limitHandler

可以作为

http.Handler

返回，那么它必须实现

ServeHTTP

，它没有显示，并且是相关的代码。@Adrian，我想现在已经满了-很抱歉编辑太晚了。

func (h *limitHandler) ServeHTTP(w http.ResponseWriter, req *http.Request) {
    select {
    case <-h.connc:


        fmt.Println("ServeHTTP");


        h.handler.ServeHTTP(w, req)

        h.connc <- struct{}{}
    default:
        http.Error(w, "503 too busy", http.StatusServiceUnavailable)
    }
}

func failOnError(err error, msg string) {
    if err != nil {
        log.Fatalf("%s: %s", msg, err)
        panic(fmt.Sprintf("%s: %s", msg, err))
    }
}
