这边尽力写出自己遇到的问题

* 原作是var resMap = mutable.Map[String,String]()
* 因为需要获取到的数据不再是原作中简单的两个字符串，而是数据库里面各种类型的数据  所以用了mutable的listbuffer  然后又类型改成any就行

    // 绑定ip和端口
    val bindingFuture = Http().bindAndHandle(Find, "localhost", 9881)
    println(s"Server online at http://localhost:9881/\nPress RETURN to stop...")
    StdIn.readLine()
    bindingFuture.flatMap(_.unbind()).onComplete(_ => system.terminate())
  }

}

其实到这边就可以结束了 原作还有一个客户端操作层 server直接启动后
进postman一样操作的 具体操作注意一下代码里面的post和get对应就行

最后是pom依赖
其实这个问题属实搞得我头大，最后也是用了下面的才成功
废话不多说直接贴

这个
如果是要用scala打jar包就一定要带上
还有这个

    <dependency>
      <groupId>org.pentahogroupId>
      <artifactId>pentaho-aggdesigner-algorithmartifactId>
      <version>5.1.5-jhydeversion>
      <scope>testscope>
    dependency>

这串代码也是研究好了很久 有jar包都没有用 alt键点了还是没有反应，
最后是把这个jar包上传到了自己的maven私有云上面
就是maven的那个setting.xml 带上自己的maven镜像 就可以了
