DropWizard石墨度量記者在config.yml無法解析

Question

我試圖配置我dropwizard石墨度量記者在我config.yml文件：

metrics: 
    reporters: 
    - type: graphite 
     host: my.graphite.host.com 
     port: 2003 
     prefix: my.prefix 

我都dropwizard度量和度量，如石墨依賴關係在我的pom.xml中。我的應用程序類或配置類中沒有關於記者的內容。我的印象是DropWizard負責MetricRegistry和記者的所有初始化和啓動。然而，當我運行我的應用程序時，我收到以下錯誤：

config.yml has an error: 

    * Failed to parse configuration at: metrics.reporters; 
Could not resolve type id 'graphite' into a subtype of [simple type, 
class io.dropwizard.metrics.ReporterFactory]: 
known type ids = [ReporterFactory, console, csv, log] 
at [Source: N/A; line: -1, column: -1] 
(through reference chain: com.example.MyConfiguration["metrics"]- 
>io.dropwizard.metrics.MetricsFactory["reporters"]) 

爲什麼「石墨」不被接受爲可接受的類型？我錯過了什麼？
