JBPM4.3 流程處理中設定流程中變數值

1.發起時：

 Map<String, Object> variables = new HashMap<String, Object>();
    variables.put("var1", "1");
    variables.put("var2", "Malt");
    Execution execution = executionService.startProcessInstanceByKey("流程key", variables);

2.處理時候

    variables = new HashMap<String, Object>();
    variables.put("var1", 2);
    variables.put("var2", "Malt2");
    taskService.completeTask(taskId, variables);

3.任務存在時

    variables = new HashMap<String, Object>();
    variables.put("var1", 3);
    variables.put("var2", "Malt3");    
    taskService.setVariables(taskId, variables);

4.在任何時候都可以設定全域性變數

    variables = new HashMap<String, Object>();
    variables.put("var1", 4);
    variables.put("var2", "Malt4");    
    executionService.setVariable(execution.getId(),variables);
