2. Parse String to Tree

这个场景是将字符串解析为JSONObject或者HashMap，不涉及绑定JavaBean对象。

3. Pars String to Java Bean

这个场景是将一个没有格式化的JSON字符串反序列化为JavaBean对象，是最常用的场景，这个是fastjson1的强项。

JDK 8

JDK 8环境下FASTJSON2比FASTJSON1快18.5%，比Jackson快134.6%。

JDK 17

JDK 17环境下FASTJSON 2和FASTJSON 1性能很接近，比Jackson快172.8%。 这个场景FASTJSON 2没有比FASTJSON 1性能接近的原因有两个：

  1. 这个FASTJSON 1的最强场景
  2. 由于JDK 17的一些限制使得在不加特别参数时，FASTJSON 2对String.value字段直接访问的优化手段无法使用限制了性能进一步提升
