API
Fastjson 解析 Tree
import com.alibaba.fastjson.*;
JSONObject jsonObj = JSON.parseObject(jsonStr);
Fastjson 解析 POJO
import com.alibaba.fastjson.JSON;
Model model = JSON.parseObject(jsonStr, Model.class
Fastjson 解析 POJO 泛型
import com.alibaba.fastjson.JSON;
Type type = new TypeReference<List<Model>>() {}.getType();
List<Model> list = JSON.parseObject(jsonStr, type);Fastjson 转换POJO 转 json 字符串
import com.alibaba.fastjson.JSON;
Model model = ...;
String jsonStr = JSON.toJSONString(model);
Fastjson 将 POJO 转换为 json 字节
import com.alibaba.fastjson.JSON;
Model model = ...;
byte[] jsonBytes = JSON.toJSONBytes(model)
Fastjson 将 POJO 作为 json 字符串写入 OutputStream
import com.alibaba.fastjson.JSON;
Model model = ...;
OutputStream os;
JSON.writeJSONString(os, model);;
Fastjson 将 POJO 作为 json 字符串写入 Writer
import com.alibaba.fastjson.JSON;
Model model = ...;
Writer writer = ...;
JSON.writeJSONString(writer, model);
