java - how to parse a JSON string into ObjectNode in Jackson? -

-

First of all, can anyone explain, what is the difference between the object node and the jesenand, and where did they use it?

Then what can I do if I want to convert a JSON string to ObjectNode?

You can: 

  object mapper mapper = new object On mapper (); JsonNode realObj = mapper.valueToTree ("{\" k1 \ ": \" v1 \ "}")

JsonNode is a super class of this object node.

You can find differences in the API.

-
I have a very strange situation with Powerbuilder 12.1. I have two issues that can be related - mainly because this is the exact same data window report. Problem # 1: You can not see the contents of Detavindo any and went nowhere, lost the ability to debug and display content Detavindo at runtime during the debug and runtime. But when you go into the data window in design mode, it prompts for the values ​​of those parameters, the content is only displayed, it is okay. Edit: Solve. This is due to a powerbiller that uses an integer rather than a long variable. The identity identifier in the database exceeds the upper limit of a PowerBuilder 16-bit integer (32767). I updated the logic for longer use, and resolved this problem # 1. ISSUE # 2: When I run the report code using the same data window mentioned in issue # 1 above, in debug mode, to create a new report file, this work Done - only in DEBUG mode Runtime failure - I got an error -1 during the runtime for the exact same...
