Clojure server-socket ClassNotFoundException error

Question

我想测试一下。

当我执行这段代码

(ns mire
  (:use [clojure.contrib server-socket duck-streams]))

我有java.io.FileNotFoundException错误。

搜索发现clojure.contrib已被弃用，我在project.clj中添加了server-socket作为依赖项，并执行leon repl来安装jar库

mire> lein repl
Retrieving server-socket/server-socket/1.0.0/server-socket-1.0.0.pom from clojars
Retrieving server-socket/server-socket/1.0.0/server-socket-1.0.0.jar from clojar

然后在emacs/cider中，我尝试使用此代码来获得相同的FileNotFoundException错误。

(ns mire
  (:use [server.socket server-socket duck-streams]))
java.io.FileNotFoundException: Could not locate server/socket/server_socket__init.class or     
server/socket/server_socket.clj on class path: 

在命令行REPL中，(use [server.socket server-socket])给出了相同的错误信息。

怎么了?我使用emacs/cider/nREPL。这是project.clj。

(defproject mire "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :dependencies [[org.clojure/clojure "1.5.1"]
                 [server-socket "1.0.0"]])

是导致错误的代码:

(ns mire
  (:use [clojure.contrib server-socket duck-streams]))
(def port (* 3 1111))
(defn mire-handle-client [in out]
  (binding [*in* (reader in)
            *out* (writer out)]
    (loop []
      (println (read-line))
      (recur))))
(def server (create-server port mire-handle-client))

Answer 1

来自在Clojure中构建Echo服务器-第2部分中的代码，这是使用server.socket的工作代码。

(ns mire
  (:use server.socket))
(import '[java.io BufferedReader InputStreamReader OutputStreamWriter])
(def port (* 3 1111))
(defn mire-handle-client [in out]
  (binding [*in* (BufferedReader. (InputStreamReader. in))
            *out* (OutputStreamWriter. out)]
        (loop []
            (println (read-line))
            (recur))))
(def server (create-server port mire-handle-client))

Answer 2

名称空间通常用点分隔。这个库中的server.socket是。

试试这个:

(ns mire (:use [server.socket]))
