Springboot API returns overlapping results for parallel run

[leoiser]

Hi, I am new to springboot. I created an API which run some process that takes around one hour and return the result. The problem is if I submit two process parallel, I am getting the same output. Pls check the below code and give me suggestions --CONTROLLER

@RestController
@RequestMapping("/task")
public class ProcessController {

@Autowired
TaskRepository taskRepository;

@Autowired
ProcessService processService;

@RequestMapping(value = "/process", method = RequestMethod.POST, consumes = "application/json", produces = "application/json")
public Map process(@RequestBody String requestBody) throws Exception {
	Map result = new LinkedHashMap();
	long taskId=0;
	
	try {

		ParameterClass param =null ;
		JSONObject requestJson = new JSONObject(requestBody);
		taskId = Long.valueOf(requestJson.getString("taskid"));
		List lst = taskRepository.findByTaskId(taskId);
		
		Task task = lst.stream().filter(p -> p.getParameterName().equals("process\_task"))
				.findFirst().orElse(null);
		if (task != null) {
			String parameterArgs = task.getParameterArg();
			param = setParameters(parameterArgs);
			
			//Log process take around one hour
			result = processService.ProcessJob(param);

			
		}
		
	} catch (Exception ex) {
		result.put("taskid", taskId);
		result.put("status", "failed");
		result.put("message", ex.getMessage());
		ex.printStackTrace();
		

	} finally {
		
		
		return result;
	}
		
	
}	

}

--SERVICE

@Service
public class ProcessServiceImpl implements ProcessService {

//Oracle DB connection
private dataLayer dbLayer 						= null;

//Setting the parameters
private  ProcessParameter inputParam				= null;

//Storing output 
private LinkedHashMap outputResult 		= null;

//storing Log details
private StringBuilder sbLog						= null;

@Override
public Map ProcessJob(ProcessParameter param) throws Exception {
	
	try
	{
		outputResult.put("jobid", param.getTask\_id());
		outputResult.put("startdate", new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a").format(System.currentTimeMillis()));
		
		sbLog.append("taskid= " + param.getTask\_id() + ")\\n");
		
		inputParam = param;
	
		// Initialize the dabaLayer object
		dbLayer = new dataLayer(param.getServer\_name(), param.getDatasource(), param.getUsername(),param.getPassword());
				
	
		if (!dbLaye
