应用场景

在Handler中执行耗时较久的程序时，等待执行过程中，客户端界面无法进行其他操作，只能等待，而通过dispatcher调度可以解决这种问题。

Handler创建Dispatcher请求

char ProviderName[128]="SIEMENS",                    //Provider名称
        ServiceName[128]="bomchange";                    //服务名称
int request_args_num= 4;                                //参数数量
//request_args为参数值 键值对形式 "key=value",例如"prop=xxx"
const char** request_args = (const char**)MEM_alloc(request_args_num * sizeof(char*));
tag_t trans_rqst=NULLTAG;
logical flag;
int isFinalState =0;
ITKCALL(DISPATCHER_create_request(
    ProviderName,//the name of the provider that will process this request
    ServiceName,//the name of the service that will process this request
    3, //the priority to assign to the request(0 LOW to 3 HIGH)
    0, //the time at which to start this request
    0, //the time at which no more repeating requests of this same type will be processed.  
    //If the interval option for repeating is NOT selected, then this paramater is unused
    0, //the number of times to repeat this request
    // 0 - no repeating
    // 1 2 3 ... - number of times to repeat this task
    1,// the length of the primary and secondary object arrays
    &attachments[i],// the array of primary objects  请求对象
    NULL,//the array of related secondary objects
    request_args_num, //the number of request arguments
    request_args,//the array of request arguments in the format of
    NULL, // a string for use by the application creating the request for use in defining a type for the request (i.e. SYSTEM, THINCLIENT, etc.)
    0, //the number of datafiles you would like to upload
    0, 
    0,
    &trans_rqst));

创建响应

1、创建响应工程

1、创建一个普通的java工程，导入依赖包，依赖包存在于DispatcherClient\lib。
2、创建下图所示的java文件

2、书写响应代码

1、com.origin.bomchange.response.DatabaseOperation.java 代码

package com.origin.bomchange.response;
import java.util.List;
import com.teamcenter.ets.load.DefaultDatabaseOperation;
import com.teamcenter.translationservice.task.TranslationDBMapInfo;
public class DatabaseOperation extends DefaultDatabaseOperation{
     /**
     * Stores translation result data on the source dataset. If there are
     * existing translation result data files, they may be replaced depending
     * upon the value of the UpdateExistingVisualizationData TaskPrep instance
     * variable.
     *
     * @param zDbMapInfo DB mapper info object.
     * @param zFileList  List of files mapped to the source file.
     *
     * @throws Exception
     */
    public void load( ) throws Exception
    {
        super.load();
        System.out.println("load....");
    } // end load()
}

2、com.origin.bomchange.response.TaskPrep.java

package com.origin.bomchange.response;
//import com.origin.log.WriteLogUtil;
import java.io.File;
import java.io.FileOutputStream;
import java.io.PrintStream;
import java.util.Arrays;
import java.util.List;
import com.teamcenter.ets.extract.DefaultTaskPrep;
import com.teamcenter.ets.request.TranslationRequest;
import com.teamcenter.soa.client.model.ModelObject;
import com.teamcenter.translationservice.task.TranslationTask;
public class TaskPrep extends DefaultTaskPrep {
    public TranslationTask prepareTask() throws Exception {
        System.out.println("=================response=================");
        TranslationTask transTask = new TranslationTask();
        //获取请求对象
        ModelObject primary_objs[] = request.getPropertyObject(
                TranslationRequest.PRIMARY_OBJS).getModelObjectArrayValue();
        //获取输入参数值的键
        String[] argKeys = request.getPropertyObject(
                TranslationRequest.TRANSLATION_ARGS_KEYS).getStringArrayValue();
        //获取输入参数值的值
        String[] argValues = request.getPropertyObject(
                TranslationRequest.TRANSLATION_ARGS_DATA).getStringArrayValue();
        List<String> argKeyList = Arrays.asList(argKeys);
        List<String> argValueList = Arrays.asList(argValues);
        System.out.println(argKeyList);
        System.out.println(argValueList);
        String root_uid = "";
        String prop_BFR = "";
        String prop_AFR = "";
        String prop_form = "";
        if (argKeys != null && argKeys.length > 0) {
            for (int i = 0; i < argKeys.length; i++) {
                if (argKeys[i].equals("task_uid") == true) {
                    root_uid = argValues[i];
                }else if(argKeys[i].equals("prop_BFR") == true){
                    prop_BFR = argValues[i];
                }else if(argKeys[i].equals("prop_AFR") == true){
                    prop_AFR = argValues[i];
                }else if(argKeys[i].equals("prop_form") == true){
                    prop_form = argValues[i];
                }
            }
        }
        if (primary_objs.length > 0) {
            FileOutputStream output_file = new FileOutputStream(this.stagingLoc
                    + File.separator + "EBOMFileList.txt");
            PrintStream uids_print_stream = new PrintStream(output_file);
            System.out.println("path-->" + this.stagingLoc + File.separator+ "EBOMFileList.txt");
            StringBuffer sb = new StringBuffer("");
            sb.append("object_uid="+primary_objs[0].getUid()+";");
            if (!root_uid.equals("")) {
                sb.append("root_uid="+root_uid+";");
            }
            if(!prop_BFR.equals("")){
                sb.append("prop_BFR="+prop_BFR+";");
            }
            if(!prop_AFR.equals("")){
                sb.append("prop_AFR="+prop_AFR+";");
            }
            if(!prop_form.equals("")){
                sb.append("prop_form="+prop_form+";");
            }
            String s = sb.toString();
            System.out.println("s--->" + s);
            uids_print_stream.print(s.substring(0,s.length() - 1));
            uids_print_stream.close();
            output_file.close();
            transTask = prepTransTask(null, null, null, "EBOMFileList.txt",
                    false, false, null, 0, null);
        }
        this.m_zTaskLogger.info("end prepareTask ebomlist ");
        return addRefIdToTask(transTask, 0);
    }
}

响应时，将EBOMFileList.txt生成在Stage相对应的任务文件夹中，将Utility所需要的参数写入txt中。

3、打成jar包

4、将导出的jar包放入DispatcherClient\lib下。

5、修改DispatcherClient\conf下Service.properties文件

1、在import中加入jar包名称”BOMchange”
2、在文件最后加入

Translator.SIEMENS.bomchange.Prepare=com.origin.bomchange.response.TaskPrep
Translator.SIEMENS.bomchange.Duplicate=false

SIEMENS是Handler请求中ProviderName，bomchange是Handler请求中服务名，等号后面是TaskPrep类的全限定名。

6、修改Module\conf下translator.xml文件

1、在标签内加入

<!-- Configuration of the bomchange -->
  <BOMchange provider="SIEMENS" service="bomchange" isactive="true" >
    <TransExecutable dir="&MODULEBASE;/Translators/bomchange" name="bomchange.bat"/>
    <Options>
      <Option name="taskid" string=""
              description="Task ID from Dispatcher Client."/>
    </Options>
  </BOMchange>
 

BOMchange为jar包名称，SIEMENS为ProviderName，bomchange为ServiceName，dir指定bomchange.bat文件的路径为Translators下bomchange文件夹。

7、书写bomchange.bat，并放在Translators下bomchange文件夹内。

@echo on
set MODULE_PATH=D:\Siemens\DC\Module
set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_45
set DC_PATH=D:\Siemens\DC\Stage\DC
SET TC_ROOT=D:\Siemens\Teamcenter10
SET TC_DATA=D:\Siemens\tcdata
call D:\Siemens\tcdata\tc_profilevars
%MODULE_PATH%\Translators\bomchange\bom_change.exe %1 %DC_PATH% 
@echo off

需根据实际情况修改路径，bat调用exe文件去执行程序。
