MyBatis-Plus 通用枚举无法正确取值

当前使用版本(必须填写清楚，否则不予处理)

3.0.3

该问题是怎么引起的？(请使用最新版(具体版本查看CHANGELOG.md),如还有该问题再提 issue!)

使用通用枚举

数据采用同service的save方法保存, 且保存后结果正常

重现步骤

1. 实体

public class UserAuth implements Serializable {

    private static final long serialVersionUID = 1L;

    @TableId(value = "auth_id", type = IdType.AUTO)
    private Integer authId;

    /**
     * 用户ID
     */
    private Integer userId;

    /**
     * 认证类型
     */
    private UserAuthType type;

    /**
     * 身份标识
     */
    private String identify;

    /**
     * token
     */
    private String token;

    /**
     * 创建时间
     */
    private LocalDateTime createdTime;

    /**
     * 更新时间
     */
    private LocalDateTime updatedTime;
}

1. 枚举类

public enum UserAuthType implements IEnum<String> {

    PASSWORD("password"), GITHUB("github");

    private String value;

    UserAuthType(String value) {
        this.value = value;
    }

    @Override
    public String getValue() {
        return this.value;
    }
}

1. 配置文件

mybatis-plus:
  mapper-locations: classpath:/mapper/*Mapper.xml
  typeAliasesPackage: cn.xxx.blog.model.entity
  typeEnumsPackage: cn.xxx.blog.model.entity.constant

1. 调用方法

QueryWrapper<UserAuth> authQueryWrapper = new QueryWrapper<UserAuth>()
                .eq("user_id", user.getUserId())
                .eq("type", UserAuthType.PASSWORD);
        UserAuth userAuth = userAuthService.getOne(authQueryWrapper);

切换到3.0-RC3可以正常使用

Comment From: miemieYaho

你把 string 换成 integer 试试,数据库也改成 integer

Comment From: qmdx

typeEnumsPackage: cn.xxx.blog.model.entity.constant 枚举类是在这里？

Comment From: banto6

@miemieYaho 尝试改成integer也不行 @qmdx 是的，版本降到3.0-RC3是可以正常工作的

Comment From: miemieYaho

方便的话在 github 上传一个能复现bug的项目,我这里一直正常使用没遇到你说的问题

Comment From: banto6

@miemieYaho git项目地址: https://github.com/buyi998/bug.git

Comment From: miemieYaho

你的项目有几个问题: 1. 去除 spring-boot-devtools ,该插件会导致很多问题,估计应该是主要原因 2. 去除 mybatis-spring-boot-starter ,mp 不需要这个 你先进行一些尝试

Comment From: banto6

@miemieYaho 非常感谢, 问题就是出在spring-boot-devtools身上, 移除后恢复正常。

Comment From: sunny0130

我遇到了同样的问题，项目里确实也有spring-boot-devtools，但遗憾的是我注释了该依赖后重新编译、启动后还是报错。

Comment From: manonglushang

我报错的原因是因为 步骤2: 配置扫描通用枚举 从 3.5.2 开始无需配置 ，重新配上就好了
