# 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。
|
||
## JDK 8
|
||
JDK 8环境下FASTJSON2比FASTJSON1快96.46%，比Jackson快74.59%。
|

|
||
EishayParseTreeString.jackson thrpt 5 775.679 ± 3.524 ops/ms
|
||
```
|
||
|
||
## JDK 11
|
||
JDK 11环境下FASTJSON2比FASTJSON1快89.11%，比Jackson快45.49%。
|
||
```java

```
|
||
|
||
## JDK 17
|
||
JDK 11环境下FASTJSON2比FASTJSON1快48.40%，比Jackson快60.37%。
|
||
```java

EishayParseTreeString.jackson thrpt 5 803.867 ± 4.779 ops/ms
|
||
```
|
||
|
||
# 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%。
|
||
```java
|
||
Benchmark Mode Cnt Score Error Units
|
||
EishayParseString.fastjson1 thrpt 5 1539.912 ± 13.148 ops/ms
|
||

|
||
EishayParseString.jackson thrpt 5 777.996 ± 3.173 ops/ms
|
||
```
|
||
|
||
## JDK 11
|
||
JDK 11环境下FASTJSON 2比FASTJSON 1快38%，比Jackson快170.6%。
|
||
```java
|
||
Benchmark Mode Cnt Score Error Units
|
||
EishayParseString.fastjson1 thrpt 5 1483.601 ± 7.487 ops/ms
|

|
||
EishayParseString.jackson thrpt 5 756.721 ± 3.526 ops/ms
|
||
```
|
||
|
||
## 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
