A successful Git branching model In this post I present the development model that I’ve introduced for some of my projects (both at work and private) about a year ago, and which has turned out to be very successful. I’ve been meaning to write about i…

目录 前言 Jackson使用工具类 Jackson配置属性 Jackson解析JSON数据 Jackson序列化Java对象 前言 Json数据格式这两年发展的很快,其声称相对XML格式有很对好处: 容易阅读: 解析速度快: 占用空间更少. 不过,JSON 和 XML两者纠结谁优谁劣,这里不做讨论,可以参见知乎上为什么XML这么笨重的数据结构仍在广泛应用?. 最近在项目中,会有各种解析JSON文本的需求,使用第三方Jackson工具来解析时,又担心当增加会减少字段,会不会出现非预期的情况,因此…

Jackson使用工具类 通常,我们对JSON格式的数据,只会进行解析和封装两种,也就是JSON字符串--->Java对象以及Java对象--->JSON字符串. public class JsonUtils { /** * Logger for this class */ private static final Logger logger = LoggerFactory.getLogger(JsonUtils.class); private final static ObjectMappe…
