示例1: ServiceLoaderBackedExtensionProvider
//设置package包名称以及导入依赖的类
package com.atomist.util
import java.util.ServiceLoader
import com.atomist.rug.RugRuntimeException
import com.typesafe.scalalogging.LazyLogging
import scala.collection.JavaConverters._
import scala.reflect.{ClassTag, _}
class ServiceLoaderBackedExtensionProvider[T: ClassTag](val keyProvider: T => String)
extends LazyLogging {
// The following can be cached as it creates issues in shared class loader hierarchies
def providerMap: Map[String, T] = {
logger.debug(s"Loading providers of type ${classTag[T].runtimeClass.getName} and class loader ${Thread.currentThread().getContextClassLoader}")
ServiceLoader.load(classTag[T].runtimeClass).asScala.map {
case t: T =>
val key = keyProvider.apply(t)
logger.debug(s"Registered provider '$key' with class '${t.getClass}'")
key -> t
case wtf =>
throw new RugRuntimeException("Extension", s"Provider class ${wtf.getClass} must implement ${classTag[T].runtimeClass.getName} interface", null)
}.toMap
}
