QUESTION
I have created a custom SQLDataset implementation where it takes a SQL query and returns a List of LinkedHashmap back to the requestcontroller to be displayed in JSP or download in Excel format.
Could you please let me know if the approach is thread safe?
SqlDataset.java
...ANSWER
Answered 2019-Feb-12 at 15:17It depends on how you use this class.
With your doPost
method in controller it is thread safe for multiple users because you create new SqlDataset
object every time.
It means it will be used only by thread which processes a single request.
Your Controller code is re-entrant and thread safe.
BTW in case if you plan to use your SqlDataset
as singleton (e.g. Spring bean or such) - it is not thread safe. It has instance variables used in process - it means SqlDataset
methods are not re-entrant.
just think about them...
do you really need
private QueryProcessor qp;
while you create new instance every time in thegetQueryResult()
method?do you really need
private ArrayList dataHeader = new ArrayList<>();
while you just return it fromgetHeaders()
- why do not just create newArrayList
beforefor
loops inside the method. ...and so on...
If you make everything passed to methods as parameters and return everything created inside methods it will be fully thread safe.
Singletons may have only immutable instance variables (logically almost constants) to keep some settings or properties applicable to any threads which use it.

My Umbraco site has a recurring task which runs every 60 mins. The problem is when Umbraco is not installed yet, the task block the installation process.
I'm trying to detect the status of my Umbraco site by this:
...ANSWER
Answered 2018-Aug-14 at 09:27You can try this solution: Override ApplicationStarted method in ApplicationEventHandler.
The method is called when all required bootups is ready. Then you can override it, set a global setting to true (maybe you can define a global setting like UmbracoIsReady). And in your recurring task, you just need to retrieve UmbracoIsReady to check.
