Dropwizard の jar 起動コマンドとその動作(出力結果)を忘れるので、備忘としてメモします。

前提

起動 jar のプロジェクトルートに移動しておきます。
コマンドの${jarName}は起動対象の jar 名に読み替えてください。

起動コマンド

以下、コマンドを記載します。

1. 引き数なしで実行

  • コマンド 

    java -jar target/${jarName}.jar

  • 出力結果 

    usage: java -jar ${jarName}.jar
       [-h] [-v] {server,check,xxxCommand} ...

positional arguments:
  {server,check,xxxCommand}
                         available commands

optional arguments:
  -h, --help             show this help message and exit
  -v, --version          show the application version and exit

  • 補足 

    positional arguments:
  {server,check,xxxCommand}
                         available commands
    には、使用できるコマンドの一覧が出力されます。

2. -v を付けて実行

  • コマンド 

    java -jar target/${jarName}.jar -v

  • 出力結果 

    0.0.1
    version番号が出力されます。

3. --versionを付けて実行

  • コマンド 

    java -jar target/${jarName}.jar --version

  • 出力結果 

    0.0.1
    これもversion番号が出力されます。

4. -hを付けて実行

  • コマンド 

    java -jar target/${jarName}.jar -h

  • 出力結果 

    usage: java -jar ${jarName}.jar
       [-h] [-v] {server,check,xxxCommand} ...

positional arguments:
  {server,check,xxxCommand}
                         available commands

optional arguments:
  -h, --help             show this help message and exit
  -v, --version          show the application version and exit

  1. と同様の出力結果となります。

5. --helpを付けて実行

  • コマンド 

    java -jar target/${jarName}.jar --help

  • 出力結果 

    usage: java -jar ${jarName}.jar
       [-h] [-v] {server,check,xxxCommand} ...

positional arguments:
  {server,check,xxxCommand}
                         available commands

optional arguments:
  -h, --help             show this help message and exit
  -v, --version          show the application version and exit

これも1.と同じ出力になります。

6. check コマンド実行

  • コマンド 

    java -jar target/${jarName}.jar check

  • 出力結果 

    INFO  [2015-12-29 07:03:15,598] io.dropwizard.cli.CheckCommand: Configuration is OK

これはymlファイルを指定しないとあまり意味がないかもしれません。

7. check コマンド実行 (yml指定-問題なし)

  • コマンド 

    java -jar target/${jarName}.jar check develop.yml

  • 出力結果 

    INFO  [2015-12-29 07:03:15,598] io.dropwizard.cli.CheckCommand: Configuration is OK

  • ymlの内容 

    # use the simple server factory if you only want to run on a single port
server:
  applicationConnectors:
    - type: http
      port: 18080
  adminConnectors:
    - type: http
      port: 18081

# Logging settings.
logging:

  # The default level of all loggers. Can be OFF, ERROR, WARN, INFO, DEBUG, TRACE, or ALL.
  level: INFO

  # Logger-specific levels.

    # Sets the level for 'com.github.ko2ic' to DEBUG.
    com.github.ko2ic: DEBUG

  appenders:
    - type: console
      timeZone: JST

8. check コマンド実行 (yml指定-問題あり)

  • コマンド 

    java -jar target/${jarName}.jar check develop.yml

  • 出力結果 

    develop.yml has an error:
  * Unrecognized field at: loggingXXX
    Did you mean?:
      - logging
      - metrics
      - server

  • ymlの内容 

    # use the simple server factory if you only want to run on a single port
server:
  applicationConnectors:
    - type: http
      port: 18080
  adminConnectors:
    - type: http
      port: 18081

# Logging settings.
loggingXXX:

  # The default level of all loggers. Can be OFF, ERROR, WARN, INFO, DEBUG, TRACE, or ALL.
  level: INFO

  # Logger-specific levels.
  loggers:

    com.github.ko2ic: DEBUG

  appenders:
    - type: console
      timeZone: JST

設定ファイルに検証に使用できそうです。

  • コマンド 

    java -jar target/${jarName}.jar check -v

  • 出力結果 

    unrecognized arguments: '-v'
usage: java -jar ${jarName}.jar
       check [-h] [file]

Parses and validates the configuration file

positional arguments:
  file                   application configuration file

optional arguments:
  -h, --help             show this help message and exit

-vオプションはないと言われます。
--versionもなさそうで、
-h、--helpオプションはありそうです。

10. check コマンド実行 (-h指定)

  • コマンド 

    java -jar target/${jarName}.jar check -h

  • 出力結果 

    usage: java -jar ${jarName}.jar
       check [-h] [file]

Parses and validates the configuration file

positional arguments:
  file                   application configuration file

optional arguments:
  -h, --help             show this help message and exit

helpが出力されます。

11. check コマンド実行 (--help指定)

    java -jar target/${jarName}.jar check --help

  • 出力結果 

    usage: java -jar ${jarName}.jar
       check [-h] [file]

positional arguments:
  file                   application configuration file

optional arguments:
  -h, --help             show this help message and exit

これもhelpが出力されます。
