我是靠谱客的博主寂寞小猫咪，最近开发中收集的这篇文章主要介绍记录使用fastjson依赖@JsonFormat设置LocaldateTime格式失效，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;

public class JsonDateSerializer extends JsonSerializer<Date> {

    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    @Override
    public void serialize(Date date, JsonGenerator gen, SerializerProvider provider)
            throws IOException {
        gen.writeString(dateFormat.format(date));

    }


}

可以使用 @JsonSerialize注解

@Entity
@Table(name = "tb_pump_alarm_msg")
public class PumpAlarmMsg extends BaseEntity implements Serializable {

    private static final long serialVersionUID = 8958304132552393076L;

    /**
     * 建筑ID
     */
    @Column(name = "site_id")
    private String siteId;


    @Column(name = "sump_name")
    private String siteName;


    @Column(name = "alarm_time")
    @JsonSerialize(using = JsonDateSerializer.class)
    private Timestamp createTime;
    /**
     * 恢复时间
     */
    @Column(name = "recovery_time")
    @JsonSerialize(using = JsonDateSerializer.class)
    private Timestamp updateTime;

    public PumpAlarmMsg( ) {

    }
}
