Question

请问这是怎么回事

CREATE TABLE user (
    id INT AUTO_INCREMENT NOT NULL,
    email VARCHAR(180) NOT NULL,
    roles JSON NOT NULL,
    password VARCHAR(255) NOT NULL,
    nome VARCHAR(255) NOT NULL,
    cognome VARCHAR(255) NOT NULL,
    UNIQUE INDEX UNIQ_8D93D649E7927C74 (email),
    PRIMARY KEY(id)
) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB'

这是错误：

 An exception occurred while executing 'CREATE TABLE user (id INT AUTO_INCREMENT NOT NULL, email VARCHAR(180) NOT NULL, roles JSON NOT NULL, password VARCHAR(255) NOT NULL, nome VARCHAR(255) NOT NULL, cognome VARCHAR(255) N  
  OT NULL, UNIQUE INDEX UNIQ_8D93D649E7927C74 (email), PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB':

JSON数据类型似乎未在MariaDB数据库上实现。根据MariaDB网站 JSON是LONGTEXT

的别名

请参见JSON DATATYPE - MariaDB

您可以改为使用varchar或text或LONGTEXT数据类型。

示例：

CREATE TABLE user (
    id INT AUTO_INCREMENT NOT NULL,
    email VARCHAR(180) NOT NULL,
    roles VARCHAR(255) NOT NULL,
    password VARCHAR(255) NOT NULL,
    nome VARCHAR(255) NOT NULL,
    cognome VARCHAR(255) NOT NULL,
    UNIQUE INDEX UNIQ_8D93D649E7927C74 (email),
    PRIMARY KEY(id)
) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;

这怎么了？
