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-jdk1.8.0_361环境中，只相当于只相当于fastjson2的75.97% ;jackson则只相当于fastjson2的40.46%; gson是fastjson2的33.42%，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_361
fastjson2 > fastjson1 > jackson > gson
jdk8 100% 75.97% 40.46% 33.42%
jdk11 100% 77.97% 42.76% 35.41%
jdk17 100% 98.30% 38.41% 35.82%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，性能是jackson/gson两倍以上。 这个场景在ecs.c7.xlarge-jdk1.8.0_361环境下，fastjson1的性能是fastjson2的27.83%，jackson的性能是fastjson2的50.51%，gson是fastjson2的42.48%%.
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70.64%和55.14%; gson不直接支持输入utf8Bytes，需要先构造字符串，性能只有fastjson2的28.89%。
性能排序如下：

这个是Java对象序列化成字符串， 这个是序列化最常用的场景之一。这个场景在fastjson中的代码如下：
Bean bean = ...;
String str = JSON.toJSONString(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20~30%。

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JavaBean二进制带类型信息反序列化的场景， 这个是代替Java/Hessian反序列化的场景，代码如下：
JSONB.parseObject(
fastjson2JSONBBytes,
Object.class,
JSONReader.Feature.SupportAutoType,
JSONReader.Feature.IgnoreNoneSerializable,
JSONReader.Feature.UseDefaultConstructorAsPossible,
JSONReader.Feature.UseNativeObject,
JSONReader.Feature.FieldBased)这个场景下，fastjson2二进制格式性能是hessian的58倍，是Java序列化的3040倍
性能排序如下：
// ecs.c7.xlarge-oracle-jdk1.8.0_361_x64
fastjson2_jsonb > fastjson2JSONB_autoTypeFilter > hessian > javaSerialize
jdk8 100% 95.97% 20.29% 3.29%
jdk11 100% 85.03% 13.21% 2.61%
jdk17 100% 81.94% 11.95% 2.47%下面是不同CPU不同JDK下的性能比较表格，第1列是阿里云机器规格，第2列是JDK的版本信息，第3列到第6列是不同库的JMH的Throughput数据，越大越好。 第4列到第6列中的百分比是Throughput相比fastjson2的比，比如第三列的百分比是hessian/fastjson2_jsonb的百分数表示。
