并发思考-actor和thread那个好点？
实验课题：测试actor和thread那个好？
实验方法：利用数据库连接池创建连接，交由线程去工作，在回收，看看程序运行状况。
实验步骤：
1.创建数据连接工具类：
import java.sql.{Connection, DriverManager}
import java.util.concurrent.LinkedBlockingQueue
import com.scala.spark.commen.util.StreamingConfigure
object DBUtil{
private val dbConnectionPool = new LinkedBlockingQueue[Connection]()
private var current_num = 0 //当前连接数
private def before(){
if (current_num > StreamingConfigure.executor_max_mysql_connection.toInt && dbConnectionPool.isEmpty()) {
print("""
|☆☆☆■■■■■■☆☆☆☆☆☆☆■■■■■■■
""".stripMargin)
Thread.sleep(2000)
before()
}else{
Class.forName(StreamingConfigure.driver)
}
}
private def initConn(): Connection = {
val conn = DriverManager.getConnection(StreamingConfigure.url, StreamingConfigure.username, StreamingConfigure.password)
conn
}
private def initConnectionPool(): LinkedBlockingQueue[Connection] = {
AnyRef.synchronized({
if (dbConnectionPool.isEmpty()) {
before()
for (i <- 1 to StreamingConfigure.executor_num_mysql_connection.toInt) {
dbConnectionPool.put(initConn)
current_num += 1
}
}
dbConnectionPool
})
}
def getInstance():Connection={
var conn = dbConnectionPool.poll()
if(conn==null){
initConnectionPool()
conn = dbConnectionPool.poll()
}
return conn
}
def releaseCon(con:Connection){
dbConnectionPool.put(con)
}
def get_current_num()={
current_num
}
}
2.创建thread访问数据库连接池
object DBUtilTest extends App{
for (i <- 1 to 10000){
ConnThread(i).start()
}
}
case class ConnThread(name:Int) extends Thread{
override def run(): Unit = {
val conn = DBUtil.getInstance()
DBUtil.releaseCon(conn)
println(s"$conn conn is $name，current_num is ${DBUtil.get_current_num()}")
}
}
3.创建Actor访问数据连接池
class DBActor extends Actor{
var count = 0
override def receive: Receive = {
case "create" =>
val conn = DBUtil.getInstance()
count += 1
println(s"$conn conn is $count")
DBUtil.releaseCon(conn)
}
}
object AkkaClient extends App{
val system = ActorSystem("DBUtil")
val dBActor = system.actorOf(Props[DBActor],"dBActor")
for (i <- 1 to 10000) dBActor ! "create"
println(">>> Press ENTER to exit <<<")
try StdIn.readLine()
finally system.terminate()
}
实验结果：运行两种访问，查看结果。

实验结论：
由上面运行效果得出：actor模型几乎运行10000次点用即时结束，thread模型确实慢了好久，整体感觉有一秒，大家可以试着运行感觉一下；当中thread在运行时（为了页面加载没有粘出所有数据太多）
线程中不存在连接的查询使用，只是打印对象地址，thread在2300 - 2400 之间就存在当前连接数的增加，即表明在线程调用时，连接不能及时回收，导致了联接的创建。而actor模型在10000级连接数不变，则说明在并发稳定上，actor支持更高的并发和稳定性。
actor模型在40000000级别连接数依然是10，这说明的不言而喻。
上面的结论如果有异议的话，可以讨论。
