Question

我可以提取

的价值

val ranking_score_path = cf.getString(stg + ".input.path.ranking_score")
  .replaceAll("_replace_date_", this_date)

和

val output_path = cf.getString(stg + ".output.path.hdfs") + tomz_date + "/"

但不是

val AS_HOST = cf.getString(stg + ".output.path.aerospike.host")
println("AS_HOST = " + AS_HOST)

我试过了

替换。用_，
添加逗号

但没有工作。

错误日志

    at com.typesafe.config.impl.SimpleConfig.findKeyOrNull(SimpleConfig.java:152)
    at ...

application.conf

production {
  input {
    path {
      local = "/home/aduser/tmp/"
      hdfs = "/user/aduser/tmp_vincent/CPA/_replace_date_/intermediate/l1/"
      ranking_score = "/home/aduser/plt/item_performance/pipeline/cpa/output/_replace_date_/predict_output/ranking_score.csv"
    }
  }
  output {
    path {
      local = "/home/aduser/tmp/"
      hdfs = "/user/aduser/dyson/display/"
      aerospike {
        host = "0.0.0.0"
        port = 3000
        namespace = "test"
        set = "spark-test2"
      }
    }
  }
}

回复@评论＃1

cf很长但重要的部分如下

... ore.csv"}},"output":{"path":{"hdfs":"/user/aduser/dyson/display/","local":"/home/aduser/tmp/"}}},"sun":{"arch": ...

努力＃1：取代了部分application.conf

    path {
          local = "/home/aduser/tmp/"
          hdfs = "/user/aduser/dyson/display/"
          ae_host = "0.0.0.0"
          ae_port = 3000
          ae_namespace = "test"
          ae_set = "spark-test2"
        }

并更改了调用方法

val AS_HOST = cf.getString(stg + ".output.path.ae_host")
println("AS_HOST = " + AS_HOST)

但仍然出现错误

Exception in thread "main" com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'production.output.path.ae_host'
at com.typesafe.config.impl.SimpleConfig.findKeyOrNull(SimpleConfig.java:152)

我在几个小时后发现了问题，我的application.conf与src.main.scala处于同一级别，并且由于我不知道的原因而部分工作。在创建src.main.resources并将application.conf放入其中后，它完美地工作。

Scala没有找到配置密钥
