您可以为此使用 no-disassemble 库。https://github.com/gtrak/no.disassemble
在 Leiningen 项目中作为插件添加：:plugins [[lein-nodisassemble "0.1.3"]]
=> (use 'no.disassemble)
nil
=> (println (disassemble (fn [] (+ 1 2))))

查看cider-decompile。仅当您的编辑器是 Emacs 时才有用，因为它是 Clojure IDE 和 Emacs 的 REPL（构建在 nREPL 之上）的扩展。

您可以调用 javap -c 命令： http ://docs.oracle.com/javase/7/docs/technotes/tools/windows/javap.html

这个怎么样：https ://github.com/nathanmarz/serializable-fn
来自自述演示：
(use 'serializable.fn)
;; note that this function being created has a function value in its closure
(def f (let [x + c 2]
(fn [a b] (x a b c))))
(println (f 1 2))
;; 5
(def b (serialize f))
(println (seq b))
