我正在运行 Lein 2 和苹果酒 0.7.0。我制作了一个使用 ring/run-jetty 启动的示例环应用程序。
(ns nimbus-admin.handler
(:require [compojure.core :refer :all]
[compojure.handler :as handler]
[clojure.tools.nrepl.server :as nrepl-server]
[cider.nrepl :refer (cider-nrepl-handler)]
[ring.adapter.jetty :as ring]
[clojure.tools.trace :refer [trace]]
[ring.util.response :refer [resource-response response redirect content-type]]
[compojure.route :as route])
(:gen-class))
(defroutes app-routes
(GET "/blah" req "blah")
(route/resources "/")
(route/not-found (trace "not-found" "Not Found")))
(def app (handler/site app-routes))
(defn start-nrepl-server []
(nrepl-server/start-server :port 7888 :handler cider-nrepl-handler))
(defn start-jetty [ip port]
(ring/run-jetty app {:port port :ip ip}))
(defn -main
([] (-main 8080 "0.0.0.0"))
([port ip & args]
(let [port (Integer. port)]
(start-nrepl-server)
(start-jetty ip port))))
然后用苹果酒连接到它,例如:
cider-connect 127.0.0.1 7888
我可以在 emacs 中导航到我的站点和评估表单,它会更新我的 nrepl 会话中正在运行的内容,这很棒。
我看不到输出,无论是(print "test") (println "test") (trace "out" 1)
最后,我的项目文件:

我开始网站lein run
编辑
我可以看到输出,仅在使用时(.println System/out msg)
