Spring集成回复消息挂起，直到超时TcpNioConnection＆＃39;发生

标签： spring-integration

我想使用spring集成与另一台服务器进行TCP通信（用C语言编写）。

服务器之间的Exchange数据是原始字节，但消息没有分隔符。

因此，我编写了自己的Serializer / Deserializer，扩展了 AbstractByteArraySerializer 。

但是，当我通过MessagingGateway发送消息时 - ＆gt; TcpOutboundGateway - ＆gt; TcpNioClientConnectionFactory，回复消息挂起，直到超时TcpNioConnection发生。

这是我的SI java配置：

@Bean(name = "loggingChannel")
public MessageChannel loggingChannel() {
    return new DirectChannel();
}

@Bean
@GlobalChannelInterceptor()
public ChannelInterceptor wiretap() {
    return new WireTap(loggingChannel(), s -> true);
}

private int port = 10101;

private String host = "10.1.3.119";

@Bean
public MessageChannel toTcp() {
    return new DirectChannel();
}

@Bean
public MessageChannel fromTcp() {
    return new DirectChannel();
}

@Autowired
public PerunGateway perunGateway;

@MessagingGateway(defaultRequestChannel = "toTcp", defaultReplyChannel = "fromTcp")
public interface PerunGateway {

    @Gateway
    byte[] sendCommand(byte[] message);
}

@Bean
@ServiceActivator(inputChannel = "toTcp")
public TcpOutboundGateway tcpOutGate() {
    TcpOutboundGateway gate = new TcpOutboundGateway();
    gate.setConnectionFactory(clientConnectionFactory());
    gate.setOutputChannelName("fromTcp");
    gate.setRequestTimeout(5000);
    return gate;
}

@Bean
public AbstractClientConnectionFactory clientConnectionFactory() {
    TcpNioClientConnectionFactory tnccf = new TcpNioClientConnectionFactory(host, port);
    tnccf.setSoTimeout(1000);
    tnccf.setSingleUse(true);
    tnccf.setSerializer(new SunByteArrayRawSerializer());
    tnccf.setDeserializer(new SunByteArrayRawSerializer());
    return tnccf;
}

发送消息后我得到输出：

有什么想法吗？

这是我的自定义反序列化方法：

@Override
public byte[] deserialize(InputStream inputStream) throws IOException {
    if (logger.isDebugEnabled()) {
        logger.debug("Available to read:" + inputStream.available());
    }

    byte[] header = new byte[2];
    header[0] = (byte) inputStream.read();
    if (header[0] < 0) {
        throw new SoftEndOfStreamException("Stream closed between payloads");
    }

    header[1] = (byte) inputStream.read();
    if (header[1] < 0) {
        throw new SoftEndOfStreamException("Stream closed between payloads");
    }

    int val = getIntFromTwoBytes(header);

    byte[] length = new byte[val];
    for (int i = 0; i < val; i++) {
        length[i] = (byte) inputStream.read();
    }

    int messageLength;
    if (val == 2) {
        messageLength = getIntFromTwoBytes(length);
    } else if (val == 4) {
        messageLength = getIntFromFourBytes(length);
    } else throw new IOException("Unexpected count of bytes that holds message length");

    byte[] answer = new byte[messageLength];
    for (int i = 0; i < messageLength; i++) {
        int bite = inputStream.read();
        if (bite < 0) {
            throw new SoftEndOfStreamException("Stream closed between payloads");
        }
        answer[i] = (byte) bite;
    }

    ByteBuffer b = ByteBuffer.allocate(2 + val + messageLength);
    b.put(header);
    b.put(length);
    b.put(answer);
    return b.array();
}

我们使用自己的二进制协议，所以我知道传入消息的确切长度。

1 个答案:

答案 0 :(得分：0)

这当然不是意图，但是我看到了，是的，超时被报告给反序列化器作为正常的EOF而不是IOException。

我们的标准原始反序列化器（期望一个套接字接近结束流）表现出这个问题...... 

fetch first

因为超时被视为EOF并且返回了部分消息（作为休息的结果）。

你的反序列化程序在获得EOF时根本不会检查它是否有部分结果...... 

if (bite < 0) {
    if (n == 0) {
        throw new SoftEndOfStreamException("Stream closed between payloads");
    }
    break;
}

...所以我看不出你的解串器如何表现出这个问题。当我们超时消息时，您的反序列化器应该得到if (bite < 0) { throw new SoftEndOfStreamException("Stream closed between payloads"); } ，这应该只是导致部分消息被丢弃。

我们需要更改NIO连接，以便反序列化器在超时后获得超时异常，但在这种情况下，反序列化器不应该导致部分消息。

我会看看我是否可以模拟一些数据来处理你的代码并回复你。

修改

我没有看到您的反序列化程序的行为，只能使用我们的标准-1。

我首先用你提供的测试;然后我把它打磨了一下 - 在开始解码数据之后你不应该抛出ByteArrayRawDeserializer;这应该是一个硬IOException（例如通过调用SoftEndOfStreamException）。

这是我的精美版本：

checkClosure()
