I'm new to this Dropwizard thing, and to JAVA as a whole. I've tried to create a basic Dropwizard project (having connection with MySQL database through Hibernate). I'm using eclipse IDE for the same. I've followed all the steps to the T, but upon typing in this command in the console -> java -jar target/hotel2-0.0.1-SNAPSHOT.jar server config.yml. I get the following error:-
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"])
Below are copies of my pom.xml and config.yml files:
config.yml -
## Configuration file for Hotel2 application.

# User password.

#Server configuration.

my configuration file :-
package com.drivedge.hotel2;
import io.dropwizard.Configuration;
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;
}
}
Where am I going wrong? I'm really new to all this Dropwizard stuff. Any help would be greatly appreciated!
