In Java, you can assign values to enums by defining a constructor and a private variable in the enum. For example an enum for Seasons of the year will have 4 constants:public enum Season {WINTER, SPRING, SUMMER, FALL}. This allows you to associate specific values with each enum constant...

枚举类型是 Java 5 中增加的一个小特性,在此之前,实现枚举的方式为定义编译期常量形式。而代码中使用编译期常量的方式在理解性和安全性方面存在不足,单纯的常量数值不能够直观的体现出其作为枚举实例的目的,且实际中无限的取值空间也不能很好的与理论上有限的枚举空间相
fastjson提供的JSON.toJSONString(...)有很多重载的方法,例如: public staticString toJSONString(Object object, SerializeConfig config, SerializerFeature... features) 所以,fastjson可以通过设置SerializeConfig来配置enum的序列化。 public static void main(String[] args) { ...
