Field injection of Concurrent hashmap

[Sowmiya]

Following my code I would like to inject a bean named deviceIdLockMap into LockDelegate. Could you please help me with it?

public class LockDelegate implements JavaDelegate {
private static final Logger LOG = LoggerFactory.getLogger(LockDelegate.class);

private Expression lockService;

@Override
public void execute(DelegateExecution execution) throws Exception {
	@SuppressWarnings("unchecked")
	ConcurrentHashMap<String, Boolean> deviceIdLockMap = (ConcurrentHashMap<String, Boolean>)lockService.getValue(execution);
	LOG.info(deviceIdLockMap.toString());
