JSON

忽略字段

由对象转换为json字符串时，增加@JSONField(serialize = _false_)即可

import com.alibaba.fastjson.annotation.JSONField;
import lombok.Data;
@Data
public class Person {
    @JSONField(serialize=false)
    private String id;
    private String name;
    private Integer age;
}

带泛型的gson转换

JsonElement labels = item.get("labels");
if (ObjectUtils.isNotEmpty(labels)) {
    Type type = new TypeToken<List<String>>() {
    }.getType();
    List<String> labelList = GSON.fromJson(GSON.toJson(labels), type);
    if (ObjectUtils.isNotEmpty(labelList)) sheet.setLabels(String.join(" ", labelList));
}
