AssemblyExecuteAdapter

BizTalk custom adapter

AssemblyExecuteAdapter

功能

更为方便的扩展BizTalk custom adapter 的交互方式，只需要实现IAssemblyExecute 接口就可以让BizTalk AssemblyExecuteAdapter 执行需要的业务逻辑。

代码

AssemblyExecuteAdapterTransmitterEndpoint.cs

通过配置需要加载的dll 文件来执行dll 内部处理逻辑

private Stream SendAssemblyExecuteAdapterRequest(IBaseMessage msg, AssemblyExecuteAdapterTransmitProperties config)

{

VirtualStream responseStream = null;

string charset = string.Empty;

IBaseMessagePart bodyPart = msg.BodyPart;

Stream btsStream;

string messageid = msg.MessageID.ToString("D");

if (null != bodyPart && (null != (btsStream = bodyPart.GetOriginalDataStream())))

{

try

{

Type assemblyExecuteType = Type.GetType(config.AssemblyName);

IAssemblyExecute assemblyexecute = (IAssemblyExecute)Activator.CreateInstance(assemblyExecuteType);

object inputparameters = null;

if (!string.IsNullOrEmpty(config.InputParameterXml))

{

XmlDocument inputXml = new XmlDocument();

inputXml.LoadXml(config.InputParameterXml);

inputparameters = assemblyexecute.GetInputParameter(inputXml);

}

Stream stream = assemblyexecute.ExecuteResponse(btsStream, inputparameters);

#region saveresponsemessage

string responsefilename = string.Empty;

if (config.SaveResponseMessagePath != string.Empty && config.SaveResponseMessagePath != "N")

{

if (!Directory.Exists(config.SaveResponseMessagePath))

Directory.CreateDirectory(config.SaveResponseMessagePath);

responsefilename = Path.Combine(config.SaveResponseMessagePath, "res_" + messageid + ".txt");

SaveFile(responsefilename, stream);

stream.Seek(0, SeekOrigin.Begin);

}

#endregion

if (config.IsTwoWay)

{

responseStream = new VirtualStream(stream);

}

}

catch(Exception e)

{

#region saveerrormessage

string errorfilename = string.Empty;

if (config.SaveErrorMessagePath != string.Empty && config.SaveErrorMessagePath != "N") {

if (!Directory.Exists(config.SaveErrorMessagePath))

Directory.CreateDirectory(config.SaveErrorMessagePath);

errorfilename = Path.Combine(config.SaveErrorMessagePath ,messageid + ".txt");

SaveFile(errorfilename, btsStream);

}

#endregion

string Source = "AssemblyExecuteAdapter";

string Log = "Application";

string Event = e.Message + "\r\n request message saved :" + errorfilename;

if (!EventLog.SourceExists(Source))

EventLog.CreateEventSource(Source, Log);

EventLog.WriteEntry(Source, Event, EventLogEntryType.Error);

throw;

}

}

return responseStream;

}
