Question

Javascript创建日期：

"created_at": new Date().toISOString().slice(0, 19).replace('T', ' ')

在java中我试图将它映射到pojo类中的java.sql.date：

public class Comment extends Model{

    private Date created_at;

    public Date getCreated_at() {
        return created_at;
    }

    public void setCreated_at(Date created_at) {
        this.created_at = created_at;
    }
}

使用preparedStatment映射时出现错误：

PreparedStatement pst = con.prepareStatement(query, Statement.RETURN_GENERATED_KEYS);
pst.setDate(1, newComment.getCreated_at());

错误：

   org.codehaus.jackson.map.JsonMappingException: Can not construct instance of java.sql.Date from String value '2017-03-27 09:28:40': not a valid representation (error: Can not parse date "2017-03-27 09:28:40": not compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:m

Answer 1

您可以使用long来接收时间值。的javascript：

{"created_at": new Date().getTime()}

和 java bean（你可以处理getter方法）：

public class Comment extends Model{

private Long created_at;

public Date getCreated_at() {
    return new Date(created_at);
}

public void setCreated_at(Long created_at) {
    this.created_at = created_at;
}

}

Answer 2

向字段created_at

添加注释

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd hh:mm:ss")

检查你的图书馆版本例如，我有，它的工作原理：
