yml配置

mybatis-plus: #扫描，多个package用逗号或者分号分隔 typeEnumsPackage: io.renren.modules.*.enums

使用方法

使用枚举@EnumValue

@Getter
public enum  UserType{
    BACKEND(1, "后台"),
    FRONT(2, "前台"),
    ;
    @JsonCreator
    UserType(Integer val, String desc) {
        this.val = val;
        this.desc = desc;
    }
    @EnumValue
    private final Integer val;
    @JsonValue
    private final String desc;
}

实现接口IEnum<T>

@Getter
public enum  UserType implements IEnum<Integer> {
    BACKEND(1, "后台"),
    FRONT(2, "前台"),
    ;
    @JsonCreator
    UserType(Integer val, String desc) {
        this.val = val;
        this.desc = desc;
    }
    private final Integer val;
    @JsonValue
    private final String desc;
       @Override
   public Integer getValue() {
       return val;
   }
}
