[大数据]fastjson 序列化时指定json的key值

json字符串中的key是下划线例如：foot_dist，而实际实体类中的属性是footDist，添加 @JSONField(name = "foot_dist")即可

package com.gblfy;

import com.alibaba.fastjson.annotation.JSONField;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Segments {
    @JSONField(name = "line_name")
    private String lineName;
    @JSONField(name = "foot_dist")
    private String footDist;
    @JSONField(name = "stat_xys")
    private String statXys;
    @JSONField(name = "stats")
    private String stats;
    @JSONField(name = "end_stat")
    private String endStat;
    @JSONField(name = "line_xys")
    private String lineXys;
    @JSONField(name = "line_dist")
    private String lineDist;
    @JSONField(name = "start_stat")
    private String startStat;
}

 //序列化时指定json的key值
    public static void main(String[] args) {
        Segments build = new Segments().builder()
                .footDist("123")
                .startStat("456")
                .stats("2").build();
        System.out.println("sss"+JSON.toJSONString(build));

    }
