JSONHelper | Convert anything into anything in one operation | JSON Processing library

Json.NET uses a DataTableConverter to convert a DataTable to and from JSON.

This one shares the same serializer with all other converters that are being used for the (de)serialization of an object, in this case one configured with a camel case naming strategy.

In order to apply a different naming strategy for a DataTable, you can implement a custom DataTableConverter in which you configure the serializer to use a different IContractResolver/DefaultContractResolver without the camel case naming strategy while (de)serializing the DataTable.

Alternativelly you might set up a whole different serializer that you pass to base.WriteJson and base.ReadJson.

It is an Object Array, not a valid JSON. Is the order/index of the values are always same? I mean High and Low will be always at index 2 and 3? If yes then read them by looping and populating a POJO.

DozerMapping can be useful. Similar solution here.

Make the method generic:

The infinate loop comes from this statement:

@Singleton annotation is enough to notify that the class is a singleton class, so i just remove the companion object and changes private constructor with a public constructor so the code will look like this:

will it really make any part of the code to run synchronously, just because the lack of an 'await' operator?

Yes. The Main method will run synchronously. This won't really matter because it's the Main method, but if you want to asynchronously wait for the tasks to complete, use await Task.WhenAll instead of Task.WaitAll. The asynchronous approach has an additional benefit in that it doesn't wrap exceptions in AggregateException.

On a side note, use await instead of ContinueWith.

Did you annotate your PHP Table class ? Tried your exemple with :

generally, you are on the right path. It is my understanding that HttpLog is a model, and you want to store the request values that to database, correct?

You write:

if we use standar filter we cannot access activejdbc db connection layer

So, the ActiveWeb filters have ordering, which is documented here: https://javalite.io/controller_filters#filter-ordering

This means that if you want a database connection available in the HTTPLogFilter, you have to register the DBConnectionFilter before the HTTPLogFilter, example:

The main class when working with Jackson is the ObjectMapper. It has a lot of options, take a look at the available methods.

This is an example of a typical helper class that uses the ObjectMapper to convert between Java objects and Strings.
