how to get node property base on node id ?

[dharmraj]

i am passing node from  UI to Back end to fetch node property based on node id and set property value .

String nodeId = req.getParameter(ID);
logger.info(nodeId);
NodeRef node = serviceRegistry.getNodeService().getNodeRef(Long.valueOf(nodeId));
if(node!= null) {
serviceRegistry.getNodeService().setProperty(node, NOTIFICATION_IS_EMAIL_SENT, true);

}

Is it correct ?

Its correct, but better to wrap as system user to avoid any permission issues. Refer the below code sample:

String nodeId = request.getParamater("nodeId"); //You can get the param from request for example

if (StringUtils.isNumeric(nodeId)) {
		final NodeRef nodeReference = AuthenticationUtil.runAs(new AuthenticationUtil.RunAsWork<NodeRef>() {
			@Override
			public NodeRef doWork() {
				return nodeService.getNodeRef(Long.valueOf(nodeId));
			}
		}, AuthenticationUtil.getSystemUserName());
				
		if (nodeReference !=null){
//Get all properties from the node
			final Map<QName, Serializable> properties = nodeService.getProperties(nodeReference); 
			
//OR

//Get A property from the node. Example: ContentModel.PROP_TITLE
final QName aProp = nodeService.getProperty(nodeReference, propQName); 


//OR

nodeService.setProperty(actionedUponNodeRef, propQName, "A value");

		}
