fastjson is a JSON parser and generator implemented in Java language with good performance, developed by Alibaba engineers.
Main features:
• Fast FAST (faster than any other Java-based parsers and generators, including jackson)
• Powerful (supports normal JDK classes including any Java Bean Class, Collection, Map, Date or enum)
• Zero dependency (no dependency on any other class library except JDK)
Sample code:
import com.alibaba.fastjson.JSON; Group group = new Group(); group.setId(0L); group.setName("admin"); User guestUser = new User(); guestUser.setId(2L); guestUser.setName("guest"); User rootUser = new User(); rootUser.setId(3L); rootUser.setName("root"); group.getUsers().add(guestUser); group.getUsers().add(rootUser); group.getUsers().add(rootUser); String jsonString = JSON.toJSONString(group); System.out.println(jsonString);The above detailed explanation of the usage method of fastjson of Java's JSON processor is all the content I have shared with you.
