如何解决springboot中LocalDateTime 返回前端Object对象的问题

nbstudy 发表于 2024-08-08 10:20:08

Mysql 数据库类型为datetime , Java Bean 为 LocalDateTime 类型，前端返回如下格式：

java 复制代码

createdAt": {
    "month": "JUNE",
    "year": 2024,
    "dayOfMonth": 21,
    "dayOfWeek": "FRIDAY",
    "dayOfYear": 173,
    "monthValue": 6,
    "hour": 9,
    "minute": 0,
    "nano": 0,
    "second": 0,
    "chronology": {
        "id": "ISO",
        "calendarType": "iso8601"
    }
}

解决方案1：将 LocalDateTime 改为Date类型。

解决方案2：手动指定JSON解析类型

java 复制代码

@JsonDeserialize(using = LocalDateTimeDeserializer.class)
@JsonSerialize(using = LocalDateTimeSerializer.class)
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss",timezone =  "GMT+8")
@TableField(value = "created_at",fill = FieldFill.INSERT)
private LocalDateTime createdAt;


@JsonDeserialize(using = LocalDateTimeDeserializer.class)
@JsonSerialize(using = LocalDateTimeSerializer.class)
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss",timezone =  "GMT+8")
@TableField(value = "updated_at",fill = FieldFill.UPDATE)
private LocalDateTime updatedAt;
