利用 fastjson 反 序列化 json为对象和对象数组

利用 fastjosn 将 .json文件 反序列化为 Java .class 和 java.util.List

反序列化函数

· parseObject

-将 json 字符串 反序列化为 java.class

@sherineZJU
List<T> temp= JSON.parseObject(fastjson,T.class); 
//transform the json to T
1
2
3
 

-fastjson 为 json格式的字符串（String类型）

-T 为 与 json格式对应的 自定义 java.class。

· parseObject

-将 json字符串 反序列化为 java.util.List

@sherineZJU
List<T> oldk = JSONArray.parseArray(fastjson,T.class); 
//transform the json to List<T>
1
2
3
 

-fastjson 为 json格式的字符串（String类型）

-List< T> 为 与 json格式对应的 自定义 java.util.List。

java.class 与 json字符串 的对应关系

注意 json字符串 的关键字一定要与 java.class 中的对应变量名相同。

– 第一个例子

json字符串

{
 "version": [
 {
 "intro": "断除堕胎，杀人，杀牛，宰羊，杀猪，宰鸡，杀大象，杀马，杀鱼，打死蚊子、螞蟻、蟑螂等，杀龙、猴子，出佛身血，自杀。",
 "degree": 1,
 " word ": "不杀生"
 },
 {
 "intro": "堕胎，杀人，杀牛，宰羊，杀猪，宰鸡，杀大象，杀马，杀鱼，打死蚊子、螞蟻、蟑螂等，杀龙、猴子，出佛身血，自杀。伤害别人。自己亲自做，唆使别人做，赞叹别人做。用器杖、毒药、明咒等。",
 "degree": -1,
