自mybatis3.1.0开始,如果你无需使用原生枚举,可配置默认枚举来省略扫描通用枚举配置 默认枚举配置
1、配置文件配置枚举所在的包

#配置枚举 支持通配符 * 或者 ; 分割 mybatis-plus.type-enums-package=com.iscas.biz.mp.test.model.enums mybatis-plus.configuration.default-enum-type-handler=org.apache.ibatis.type.EnumOrdinalTypeHandler |
2、定义一个枚举,在需要存入数据库的字段上加上@EnumValue注解

package com.iscas.biz.mp.test.model.enums; import com.baomidou.mybatisplus.annotation.EnumValue; import com.fasterxml.jackson.annotation.JsonCreator; import com.fasterxml.jackson.annotation.JsonValue; import com.fasterxml.jackson.annotation.JsonView; import com.iscas.biz.mp.test.model.TestEntity; import lombok.Getter; import java.util.Objects; /** * //TODO * * @author zhuquanwen * @vesion 1.0 * @date 2020/4/5 15:23 * @since jdk1.8 */ public enum SexEnum /*implements IEnum<Integer>*/ { /** * 男 * */ MAN(1, "男"), /** * 女 * */ WOMEN(2, "女"); @EnumValue private final int code; @JsonValue public int getCode() { return this.code; } public String getDescription() { return description; } private final String description; SexEnum(int val, String description) { this.code = val; this.description = description; } @JsonCreator public static SexEnum getByCode(int code) { for (SexEnum value : SexEnum.values()) { if (Objects.equals(code, value.getCode())) { return value; } } return null; } /* @Override public Integer getValue() { return code; }*/ } |
3、测试实体使用枚举

package com.iscas.biz.mp.test.model; import com.iscas.biz.mp.test.model.enums.SexEnum; import lombok.Data; /** * //TODO * * @author zhuquanwen * @vesion 1.0 * @date 2020/4/5 15:22 * @since jdk1.8 */ @Data public class TestEntity { private String name; private SexEnum sex; } |
4、测试读取和存储带有枚举的实体
