From source file:org.springframework.integration.ip.tcp.connection.TcpMessageMapper.java

protected final void addStandardHeaders(TcpConnection connection, MessageBuilder<?> messageBuilder) {
    String connectionId = connection.getConnectionId();
    messageBuilder.setHeader(IpHeaders.HOSTNAME, connection.getHostName())
            .setHeader(IpHeaders.IP_ADDRESS, connection.getHostAddress())
            .setHeader(IpHeaders.REMOTE_PORT, connection.getPort())
            .setHeader(IpHeaders.CONNECTION_ID, connectionId);
    if (this.applySequence) {
        messageBuilder.setCorrelationId(connectionId)
                .setSequenceNumber((int) connection.incrementAndGetConnectionSequence());
