表中的有些字段值是固定的,例如性别(男或女),此时我们可以使用MyBatis-Plus的通用枚举 来实现
数据库表添加字段sex
创建通用枚举类型
package com.example.enums;
import com.baomidou.mybatisplus.annotation.EnumValue;
import lombok.Getter;
@Getter
public enum SexEnum {
MALE(1, "男"),
FEMALE(0, "女")
;
@EnumValue//标记数据库存的值是code
private Integer code;
private String name;
SexEnum(Integer code, String name) {
this.code = code;
this.name = name;
}
}
配置扫描通用枚举
mybatis-plus:
configuration:
# 配置MyBatis日志
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
global-config:
db-config:
# 配置MyBatis-Plus操作表的默认前缀
table-prefix: t_
id-type: assign_id
# 配置扫描通用枚举
type-enums-package: com.example.enums
测试
@Test
public void testEnum() {
User user = new User();
user.setName("enum");
user.setAge(18);
user.setSex(SexEnum.MALE);
//==> Preparing: INSERT INTO t_user ( id, name, age, sex ) VALUES ( ?, ?, ?, ? )
//==> Parameters: 1657370519951040514(Long), enum(String), 18(Integer), 1(Integer)
//<== Updates: 1
userMapper.insert(user);
}
