4.6. 测试结果

JSON解析器性能曲线图：

JSON生成器性能曲线图：

说明：

  • 在JSON解析/反序列化处理性能上，okjson比fastjson快了近一倍(75%)。
  • 在JSON生成/序列化处理性能上，okjson比fastjson快了少许(7%)

其它说明：

  • fastjson静态类名为JSON取名不好，容易和其它JSON库冲突，或许温少就是这么霸气。okjson静态类名为OKJSON，比较低调 :)
  • 实体类中加了很多setter和getter是为了fastjson，okjson并不需要。okjson甚至连实体类构造方法都没有要求必须有，作为通用框架要兼容各种各样的场景。
