我们正尝试使用lein ring uberwar命令在JBoss上对Leiningen项目进行测试部署。在我尝试阅读属性文件之前，我取得了巨大的成功。
我有一个将属性文件读入地图的函数：
(defn load-properties
[file-name]
(with-open [^java.io.Reader reader (io/reader file-name)]
(let [properties (java.util.Properties.)]
(.load properties reader)
(into {} (for [[k v] properties] [(keyword k) (read-string v)])))))
我这样使用它：
(def settings (load-properties "application.properties"))
“application.properties”是项目目录中文件的名称。使用lein run一切都很好，但是当我创建独立war并将它转换为JBoss时，这就是堆栈跟踪：
16:51:08,140 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/kente].[kente.core/application servlet]] (http-/127.0.0.1:8080-1) Allocate exception for ser

我注意到你可以设置一个名为:war-resources-path的defproject键，所以我将我的属性文件放入$ PROJECT_ROOT / war-resources目录（the default），我还没有好运。
是否有人知道使用lein ring uberwar从属性文件中读取的最佳方式？
答案 0 :(得分：1)
jar / war中的条目不是文件。您应该使用clojure.java.io/resource而不是clojure.java.io/file或裸路径字符串来引用属性（以及战争中的任何其他类型的资源）。这将适用于文件系统上的本地资源以及战争中的资源。
您可以将资源放在项目根目录中的资源目录中，或者放在由资源路径指定的其他目录中，然后它们在类路径中可用，并且当您使用lein环构建一个时也将包含在战争中
