使用immutant服务器从浏览器访问页面时出错

Question

$ lein new pedestal-service peddy

然后将以下文件添加到immutant文件夹中

(ns immutant.init
  (:require [immutant.web :as web]
            [io.pedestal.http :as http]
            [peddy.service :as app]))

(web/start-servlet "/" (::http/servlet (http/create-servlet app/service)))

在那之后

$ lein immutant deploy peddy

然后

$ lein immutant run

使用nrepl声明的不变服务器

但当我尝试在浏览器中打开页面时，它抛出错误

我使用的是immutant 1.1.4和pedestal-service 0.4.0

这是由Servlet规范3.1版中的added --基座using .getContentLengthLong()引起的。Immuant1.x基于JBoss AS7，它使用规范的3.0版本。这意味着你将不能在任何3.1版本之前的容器中使用0.4.0。
