The above is the error message，The reason is that the project ismavenproject，But I useWhen org/json/JSONObject, the jar package is not imported using maven's data warehouse, but right-click the project to add the property, and the program runs to useThe org/json/JSONObject is reported as an error, just change it to the following method (order the version yourself).  Record it so that you won't forget it later
