Class TopiaServiceSupportImpl

java.lang.Object

org.nuiton.topia.persistence.internal.support.TopiaServiceSupportImpl

All Implemented Interfaces:

TopiaServiceSupport

public class TopiaServiceSupportImpl
extends Object
implements TopiaServiceSupport

This is the default TopiaServiceSupport implementation. It will look in TopiaApplicationContext.getConfiguration() to find services declarations and associated configuration. All of those properties match the topia.service.* prefix. A service is declared by giving it a name and the implementation class FQN by following the pattern.

 topia.service.myServiceName=com.my.company.my.app.MyServiceImpl
 

Here, myServiceName is the name of the service, you can choose any String. Value must be the FQN of class that provide an empty constructor and implements TopiaService. To passes configuration to a service, you can do as follow:

 topia.service.myServiceName=com.my.company.my.app.MyServiceImpl
 topia.service.myServiceName.myConfigurationDirective=myConfigurationValue
 

When TopiaService.initTopiaService(org.nuiton.topia.persistence.TopiaApplicationContext, java.util.Map) will be called, the given map will contain a single entry which key is "myConfigurationDirective" and value is "myConfigurationValue".
