Parse JSON data using Java

When you want to transmit multiple data in the background on a webpage, sometimes the data is still multiple dynamic lists. when the data is complex, JavaScript programmers like to process them as JSON strings, the backend needs to parse the JSON string after receiving it. Fortunately, there is JSON-Lib. This Java class package is used to convert bean, MAP and XML into JSON and convert JSON back to bean and dynabean.
