Dropwizard：config.ymlにエラーがあります

Question

私はこのDropwizardのこと、そしてJAVA全体については新しいです。私は、基本的なDropwizardプロジェクト（Hibernateを通してMySQLデータベースとの接続を持つ）を作成しようとしました。私は同じもののEclipse IDEを使用しています。私はすべての手順をTに従いましたが、このコマンドをコンソールで入力する際に​​ - > java -jar target/hotel2-0.0.1-SNAPSHOT.jarサーバーconfig.ymlを入力してください。私は次のエラーを取得する： - 以下

config.yml has an error: 
* Failed to parse configuration at: logging; Can not instantiate value of type [simple type, class io.dropwizard.logging.LoggingFactory] from String value (''); no single-String constructor/factory method at [Source: N/A; line: -1, column: -1] (through reference chain: com.drivedge.hotel2.HotelMgntConfiguration["logging"]) 

は私のpom.xmlとconfig.ymlファイルのコピーです：

config.yml -

## Configuration file for Hotel2 application. 
--- 
# User login. 
logging: 
login: javaeeeee 
# User password. 
password: crimson 

#Server configuration. 
server: 
    applicationConnectors: 
     - type: http 
      port: 9090 
     - type: https 
      port: 9090 
      keyStorePath: hotel2.keystore 
      keyStorePassword: crimson 

# Database settings. 
database: 
    # the name of the JDBC driver, mysql in our case 
    driverClass: com.mysql.jdbc.Driver 
    # the username 
    user: root 
    # the password 
    password: drivedge12 
    # the JDBC URL; the database is called Hotel2 
    url: jdbc:mysql://localhost:3306/hotelmanagement

私の設定ファイル： -

import com.fasterxml.jackson.annotation.JsonProperty; 
import io.dropwizard.db.DataSourceFactory; 
import javax.validation.Valid; 
import javax.validation.constraints.*; 
//import org.apache.tomcat.jdbc.pool.DataSourceFactory; 

public class HotelMgntConfiguration extends Configuration { 
    /*// /** 
    * A factory used to connect to a relational database management system. 
    * Factories are used by Dropwizard to group together related configuration 
    * parameters such as database connection driver, URI, password etc. 
    */ 

    @NotNull 
    @Valid 
    @JsonProperty 
    private DataSourceFactory database; 

    /** 
    * A getter for the database factory. 
    * 
    * @return An instance of database factory deserialized from the 
    * configuration file passed as a command-line argument to the application. 
    */ 

    public DataSourceFactory getDataSourceFactory() { 
     return database; 
    } 

    public void setDatabase(DataSourceFactory database) { 
     this.database = database; 
    } 
} 

どこが間違っていますか？私はこのDropwizardのすべてのものに本当に新しいです。どんな助けでも大歓迎です！

config.ymlからlogging:を削除するか、exampleのようにログを設定してください。
