Transform JSON data into Java objects using the Java reflection mechanism

Net.sf.json.JSONObject provides us with a Tobean method for converting to Java objects, which is much more powerful, with the use of the JDK's reflection mechanism as a simple helper tool, some data types need to be converted and scaled as needed. You can handle long and date types here.

only supports the processing of a single Jsonobject object, for complex JSON objects, such as jsonarray arrays, consider traversing first, getting jsonobject before processing.
