通用枚举

数据库表添加字段sex

创建通用枚举类型

package com.xxxx.mybatisplus.enums;

import com.baomidou.mybatisplus.annotation.EnumValue;
import lombok.Getter;

@Getter
public enum SexEnum 

    MALE(1,"男"),FEMALE(2,"女");



    @EnumValue // 将注解所标识的属性的值存储到数据库中
    private Integer sex;
    private String sexName;

    SexEnum(Integer sex, String sexName) 
        this.sex = sex;
        this.sexName = sexName;
    

配置扫描通用枚举

测试

package com.xxxx.mybatisplus;

import com.xxxx.mybatisplus.enums.SexEnum;
import com.xxxx.mybatisplus.mapper.UserMapper;
import com.xxxx.mybatisplus.pojo.User;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class MyBatisPlusEnumTest 

    @Autowired
    private UserMapper userMapper;

    @Test
    public void test()
    
        User user = new User();
        user.setName("admin");
        user.setAge(33);
        user.setSex(SexEnum.MALE);
        int result = userMapper.insert(user);
        System.out.println("result = "+result);
