- First step is deploying your bpmn files to the camunda engine.
- Add this code to your message handler in the Symphony bot code:
ProcessInstance instance = processInstanceClient.getProcessInstance(inboundMessage.getStream().getStreamId().replace("_", "%"));
if (instance == null) {
if (action != null) {
ProcessDefinitionInfo info = processInstanceClient.getProcessDefinitionIdFromDeploymentName(action.getAction());
Map<String, ValueType> variableMap = new HashMap<>();
variableMap.put("streamId", new ValueType(inboundMessage.getStream().getStreamId().replace("_", "%")));
variableMap.put("email", new ValueType(inboundMessage.getUser().getEmail()));
for (String parameter : action.getParameters().keySet()) {
variableMap.put(parameter, new ValueType(action.getParameters().get(parameter)));
}
processInstanceClient.startProcessInstance(variableMap, info.getId());
}
} else {
if(action!=null){
processInstanceClient.setProcessVariable(instance.getId(),action.getAction(),"true");
}
for (String parameter : action.getParameters().keySet()) {
processInstanceClient.setProcessVariable(instance.getId(),parameter,action.getParameters().get(parameter));
}
Task task = taskClient.getTask(instance.getId(), inboundMessage.getUser().getEmail());
System.out.println(task.getId());
taskClient.completeTask(task.getId());
}
