Typesafe配置 - reference.conf的不同行为?

在我看来,application.conf和reference.conf的行为有所不同。我知道reference.conf的目的是“安全回退”配置,每次都有效,而application.conf是特定的。但是我希望从解析配置的角度来看,从其中任何一个加载的配置都会表现得完全相同。

我面临的是,如果配置在application.conf中,它可以正常工作,当同一个文件重命名为reference.conf时,它不起作用。

结算差异是双引号。我的配置如下:

akka {
  ... standard akka configuration ...
}

webserver.port = 8080
webserver.bindaddress = "0.0.0.0"

配置设置在代码中加载如下:

  val webserver_port_key = "webserver.port"
  val webserver_bindaddress_key = "webserver.bindaddress"
  protected val webserver_bindaddress = ConfigFactory.load().getString(webserver_bindaddress_key)
  protected val webserver_port = ConfigFactory.load().getInt(webserver_port_key)

我错过了什么吗?当reference.conf无法绑定时,我仔细检查了端口8080是否空闲。

感谢提示

更新: 从log-config-on-start = on开始: - 当它在application.conf中时

# application.conf: 60-61
"webserver" : {
    # application.conf: 61
    "bindaddress" : "0.0.0.0",
    # application.conf: 60
    "port" : 8080
}

- 当它在reference.conf中时

# reference.conf: 60-61
"webserver" : {
    # reference.conf: 61
    "bindaddress" : "0.0.0.0",
    # reference.conf: 60
    "port" : 8080
}

发现问题:

# application.properties
"webserver" : {
    # application.properties
    "bindaddress" : "\"0.0.0.0\"",
    # application.properties
    "port" : "8080"
}

似乎bindaddress属于不同的类型,因为它在日志中的显示方式不同。

在任何一种情况下,在配置中使用此设置启用Akka完整配置打印:

log-config-on-start = on

然后比较两种配置以查看它们不匹配的位置。如果它们是相同的,它们应该以相同的方式工作。我怀疑你定义bindaddress的方式是不同的,即字符串与其他类型。
