这个是最常用的场景，将JSON格式字符串反序列化为Java对象，这个场景在fastjson中的代码如下：
String str = "...";
Bean bean = JSON.parseJSONObject(str, Bean.class);这个场景是fastjson1最强的场景；
在ecs.c7.xlarge-oracle-jdk1.8.0_341_x64环境中，只相当于只相当于fastjson2的76.07% ;jackson则只相当于fastjson2的39.15%; gson是fastjson2的33.18%，也就是说这个最常见的反序列化场景，fastjson2的性能差不多是jackson/gson的三倍。
性能排序如下：
// ecs.c7.xlarge-oracle-jdk1.8.0_341_x64
fastjson2 > fastjson1 > jackson > gson
jdk8 100% 76.07% 39.15% 33.18%
jdk11 100% 73.15% 39.20% 34.59%
jdk17 100% 91.18% 35.55% 33.98%
jdk18 100% 85.52% 36.21% 28.54%
jdk19 100% 86.91% 37.48% 29.09%fastjson2在JDK11和JDK8的算法不同，导致这个场景下，fastjson2在JDK8的表现比JDK11下好，JDK17/18/19由于JDK自身性能优化，使得JDK17/18/19性能更好。JDK 18/19比JDK 17性能显著提升。

这个场景是将格式化过的JSON格式字符串反序列化为Java对象，这个场景fastjson1的parse算法不擅长的。这个场景fastjson2表现仍然非常好。 这个场景在ecs.c7.xlarge-oracle-jdk1.8.0_341_x64环境下，fastjson1的性能是fastjson2的27.15，jackson的性能是fastjson2的50.08%，gson是fastjson2的42.89%%.
这个场景在fastjson中的代码如下：
// 这里输入的是格式化过后的json字符串
String str = "{\n" +
"\t\"id\":123\n" +
"}";
Bean bean = JSON.parseJSONObject(str, Bean.class);性能排序分别如下：

这个场景是将JSON格式字符串反序列化为JSONObject，这也是一个最常见的场景之一，这个场景在fastjson中的代码如下：
String str = "...";
JSONObject jsonObject = JSON.parseJSONObject(str);fastjson2在这个场景也表现了远超fastjson1/jackson/gson的性能。 在不同的环境中，fastjson1和jackson都只能相当于fastjson2性能的40%~60%，gson则更差一些。

这个是将UTF8格式的byte数组反序列化为Java对象，这个场景在缓存和RPC场景中常用。
这个场景在fastjson中的代码如下：
byte[] utf8Bytes = ...;
Bean bean = JSON.parseJSONObject(utf8Bytes, Bean.class);这个场景fastjson2同样表现出了卓越的性能；在JDK8下，fastjson1和jackson的性能分别之后fastjson2的71.23%和53.76%; gson不直接支持输入utf8Bytes，需要先构造字符串，性能只有fastjson2的28.3%。

这个是Java对象序列化成UTF格式的byte数组， 这个是最常用的场景之一，在缓存和RPC场景常用。gson不直接支持，需要先序列化为String再转换为UTF8格式的byte数组。
这个场景在fastjson中的代码如下：
Bean bean = ...;
byte[] utf8Bytes = JSON.toJSONBytes(bean);在这个最常用的序列化场景，fastjson2表现出远超fastjson1/jackson/gson的性能；这个场景gson表现很差，只有fastjson2的1/5不到，在JDK 17下差距更大。

这个场景是将Java对象序列化为二进制的byte数组，是缓存序列化和RPC场景使用序列化协议的典型场景。
fastson2内置支持二进制格式jsonb，jsonb是fastjson2为了RPC场景设计的序列化和反序列化设置的高性能序列化协议。
jsonb有两种映射方式，将Java对象映射为类似JSONObject的KV格式，也可以映射类似JSONArray的数组格式。
fastjson2JSONBArrayMapping的代码如下：
Bean bean = ...;
byte[] jsonbBytes = JSONB.toBytes(bean, JSONWriter.Feature.BeanToArray);fastjson2JSONB的代码如下：
Bean bean = ...;
byte[] jsonbBytes = JSONB.toBytes(bean);fastjson2UTF8Bytes的代码如下：
Bean bean = ...;
byte[] utf8Bytes = JSON.toJSONBytes(bean);这个场景下，jsonb的性能非常好，在JDK 11/17下性能更好，hessina和java内置序列化都表现很差。

这个场景是将二进制的byte数组反序列化为Java对象，是缓存序列化和RPC场景使用序列化协议的典型场景。
fastjson2JSONBArrayMapping的代码如下：
byte[] jsonbBytes = JSONB.toBytes(bean, JSONWriter.Feature.BeanToArray);
Bean bean = JSONB.parseObject(jsonbBytes, Bean.class, JSONReader.Feature.SupportArrayToBean);fastjson2JSONB的代码如下：
byte[] jsonbBytes = JSONB.toBytes(bean);
Bean bean = JSONB.parseObject(jsonbBytes, Bean.class);fastjson2UTF8Bytes的代码如下：
byte[] utf8Bytes = JSON.toJSONBytes(bean);
Bean bean = JSON.parseObject(utf8Bytes, Bean.class);性能排序如下：
// ecs.c7.xlarge-oracle-jdk1.8.0_341_x64
这个场景下，jsonb的性能非常好，在JDK 11/17下性能更好，hessina表现很差，java内置序列化都表现极差。
