Fastjson is a high-performance and complete JSON library written in Java language. It uses an "assumed ordered fast matching" algorithm to improve the performance of JSON Parse to the extreme. It is currently the fastest JSON library in the Java language. The Fastjson interface is simple and easy to use, and has been widely used in various application scenarios such as cache serialization, protocol interaction, Web output, and Android clients.
fastjson是阿里巴巴的开源JSON解析库,它可以解析JSON格式的字符串,支持将Java Bean序列化为JSON字符串,也可以从JSON字符串反序列化到JavaBean。其目前已经被广泛应用在各种场景中,包括cache存储、RPC通讯、MQ通讯、网络协议通讯、Android客户端、Ajax服务器处理程序等等。
fastjson主要特点:
快速FAST (比其它任何基于Java的解析器和生成器更快,包括jackson)
强大(支持普通JDK类包括任意Java Bean Class、Collection、Map、Date或enum)
零依赖(没有依赖其它任何类库除了JDK)
示例代码:
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); String jsonString = JSON.toJSONString(group); System.out.println(jsonString);
