如何使用SetBytesProperty和GetBytesProperty WebSphere MQ中？ [英] How to use SetBytesProperty and GetBytesProperty in WebSphere MQ?
问题描述
我有一个 SetBytesProperty / GetBytesProperty 方法对上 MQMessage 类（我使用WebSphere MQ客户端7.0.1.6）。我可以成功发送为sbyte 数组中的属性来排队，但一旦我设法得到它回来读消息我总是空。
I have a problem with SetBytesProperty / GetBytesProperty methods pair on MQMessage class (I'm using WebSphere MQ Client 7.0.1.6). I can successfully send sbyte array in property to queue but once I try to get it back in read message I always get null.
下面是最简单的code我用它来重现问题。
Here is the simplest code I use to reproduce the issue.
[TestFixture]
public class MQQueueTests {
public const string MessageContent = "<test>This is test message</test>";
[Test]
public void PutAndGetMessage() {
Environment.SetEnvironmentVariable("MQCCSID", "437");
var properties = new Hashtable
{
{MQC.HOST_NAME_PROPERTY, "TestServer"},
{MQC.CHANNEL_PROPERTY, "Test.Channel"},
{MQC.PORT_PROPERTY, 1415}
};
using (var manager = new MQQueueManager("Test.Queue.Manager", properties)) {
using (MQQueue queue = manager.AccessQueue("Test.Queue",
MQC.MQOO_OUTPUT | MQC.MQOO_INPUT_AS_Q_DEF)) {
MQMessage message = new MQMessage();
message.SetBytesProperty("testBytesValue",
new sbyte[] { 8, 12, 22, 48, 68, 71, 92, 104 });
message.WriteUTF(MessageContent);
queue.Put(message);
MQMessage readMessage = new MQMessage();
queue.Get(readMessage);
sbyte[] array = readMessage.GetBytesProperty("testBytesValue");
Assert.IsNotNull(array); // <-- FAILS!
Assert.AreEqual(MessageContent, readMessage.ReadUTF());
queue.Close();
}
manager.Disconnect();
}
}
}
东西传入消息属性排队 - 我可以看到服务器上的东西在WebSphere MQ资源管理，但它并不像我传递的数组（在收到新邮件时，随着时间的推移它甚至改变）：
Something is passed in message property to queue - I can see something in WebSphere MQ Explorer on the server but it doesn't look like my passed array (it even change over time when new messages are received):
当我打开跟踪（ strmqtrc ）的MQ客户端，我可以看到相同的值，写和客户端阅读：
When I turn on tracing (strmqtrc) on MQ Client I can see the same value wrote and read by the client:
这是present日志时，将消息发送到队列：
This is present in log when putting message to the queue:

因此，在发送和接收我看到同样正确的字节数组。但是，在.NET code中的属性值空：
每隔 GetXXXProperty 和 SetXXXProperty 方法，对工作没有任何问题。
Every other GetXXXProperty and SetXXXProperty method pair works without any problem.
编辑：
我证实，它不运行WebSphere MQ客户端的同一版本的多个计算机上工作，我也验证了它不与其它code工作。它的工作原理，如果我重写测试Java和使用Java API，而不是！
I validated that it doesn't work on multiple computers running same version of WebSphere MQ clients and I also validated that it doesn't work with another code. It works if I rewrite the test to Java and use Java API instead!
我也有问题，发送的信息有针对性地 MQTopic 的任何财产 - 我得到的MQException：MRQC_HEADER_ERROR 。此外它工作在Java中没有问题。
I also have problems with sending any property in message targeted to MQTopic - I get MQException : MRQC_HEADER_ERROR. Again it works in Java without problem.
推荐答案
我能够获得的价值。我可以看到返回的数组有相同值的那些发送的消息中。这里是C＃代码段我用了。
I am able to get the value. I can see the returned array has the same values as the ones in the sent message. Here is the C# snippet I used.
MQMessage message = new MQMessage();
message.SetBytesProperty("testBytesValue", new sbyte[] { 8, 12, 22, 48, 68, 71, 92, 104 });
message.WriteUTF(MessageContent);
queue.Put(message);
MQMessage readMessage = new MQMessage();
queue.Get(readMessage);
sbyte[] array = readMessage.GetBytesProperty("testBytesValue");
Console.Write(array);
