Hibernate OneToOne注解配置

1. Hibernate Annotation注解OneToOne

原理就不介绍了



2. 数据字典表



tb_addressInfo





Sql代码


CREATE TABLE `tb_addressinfo` (

`id` int(11) NOT NULL AUTO_INCREMENT,

`detail` varchar(255) DEFAULT NULL,

`name` varchar(255) DEFAULT NULL,

`userInfo_id` int(11) DEFAULT NULL,

PRIMARY KEY (`id`),

UNIQUE KEY `id` (`id`),

UNIQUE KEY `userInfo_id` (`userInfo_id`),

KEY `FK2F779271FC1A0B7B` (`userInfo_id`),

CONSTRAINT `FK2F779271FC1A0B7B` FOREIGN KEY (`userInfo_id`) REFERENCES `tb_userinfo` (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;



tb_userinfo



Sql代码


CREATE TABLE `tb_userinfo` (

`id` int(11) NOT NULL AUTO_INCREMENT,

`name` varchar(255) DEFAULT NULL,

PRIMARY KEY (`id`),

UNIQUE KEY `id` (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
