Example 6 with NamedThreadFactory

use of com.alibaba.dubbo.common.utils.NamedThreadFactory in project dubbo by alibaba.

the class MinaClient method doOpen.

@Override
protected void doOpen() throws Throwable {
    connectorKey = getUrl().toFullString();
    SocketConnector c = connectors.get(connectorKey);
    if (c != null) {
        connector = c;
    } else {
        // set thread pool.
        connector = new SocketConnector(Constants.DEFAULT_IO_THREADS, Executors.newCachedThreadPool(new NamedThreadFactory("MinaClientWorker", true)));
        // config
        SocketConnectorConfig cfg = (SocketConnectorConfig) connector.getDefaultConfig();
        cfg.setThreadModel(ThreadModel.MANUAL);
        cfg.getSessionConfig().setTcpNoDelay(true);
        cfg.getSessionConfig().setKeepAlive(true);
        int timeout = getTimeout();
        cfg.setConnectTimeout(timeout < 1000 ? 1 : timeout / 1000);
        // set codec.
        connector.getFilterChain().addLast("codec", new ProtocolCodecFilter(new MinaCodecAdapter(getCodec(), getUrl(), this)));
        connectors.put(connectorKey, connector);
    }

Example 7 with NamedThreadFactory

use of com.alibaba.dubbo.common.utils.NamedThreadFactory in project Hotchpotch by carryxyh.

the class EnhancedThreadPoolTest method testEnhancedThreadPool.

/**
 * it print like this:
 * thread number in current pool:1,  task number in task queue:0 executor size: 1
 * thread number in current pool:2,  task number in task queue:0 executor size: 2
 * thread number in current pool:3,  task number in task queue:0 executor size: 3
 * thread number in current pool:4,  task number in task queue:0 executor size: 4
 * thread number in current pool:5,  task number in task queue:0 executor size: 5
 * thread number in current pool:6,  task number in task queue:0 executor size: 6
 * thread number in current pool:7,  task number in task queue:0 executor size: 7
 * thread number in current pool:8,  task number in task queue:0 executor size: 8
 * thread number in current pool:9,  task number in task queue:0 executor size: 9
 * thread number in current pool:10,  task number in task queue:0 executor size: 10
 * thread number in current pool:10,  task number in task queue:4 executor size: 10
 * thread number in current pool:10,  task number in task queue:3 executor size: 10
 * thread number in current pool:10,  task number in task queue:2 executor size: 10
 * thread number in current pool:10,  task number in task queue:1 executor size: 10
 * thread number in current pool:10,  task number in task queue:0 executor size: 10
 *
 * we can see , when the core threads are in busy , the thread pool create thread (but thread nums always less than max) instead of put task into queue.
