Spring项目打包Jar时出现Lombok重写兼容错误

我在基于Spring的Java IntelliJ项目中打包Jar文件时遇到编译错误：Lombok的@Getter注解自动生成的get_status()方法与父类Model中的get_status()方法冲突，返回类型Subscription.Status（枚举类型）和父类的java.lang.String不兼容，且我并未主动重写该方法。

相关代码片段：

@Getter @Setter
private Status _status;

完整错误信息：

java: get_status() in <directive>.models.users.sub_users.subscriptions.Subscription cannot override get_status() in <directive>.models.Model
return type <directive>.models.users.sub_users.subscriptions.Subscription.Status is not compatible with java.lang.String

该问题仅出现在这个枚举属性上，其他枚举属性使用Lombok注解均正常。以下是Subscription类的完整代码：

/**
 * Defines the kind of subscription a user is having.
 * Only Artists and Bands can have a paying subscription.

@ToString
public class Subscription extends Model {

    /**
     * The User that uses this Subscription.

    @Getter
    private User _user;

    /**

     * Will also determine the price.
     */
    @Getter
    private Type _type;

    /**

    @Getter @Setter

1. 修改属性名称规避冲突 #

直接修改子类中属性的名称，避免和父类属性（或其生成的getter）重名。比如把_status改为_subscriptionStatus，Lombok会生成get_subscriptionStatus()方法，自然不会和父类的get_status()冲突：

@Getter @Setter
private Status _subscriptionStatus;

2. 自定义Getter方法名称 #

通过Lombok注解指定自定义的getter方法名，绕过默认的命名规则：

@Getter(getterName = "getSubscriptionStatus")
@Setter(setterName = "setSubscriptionStatus")
private Status _status;

注：部分Lombok版本可能使用@Accessor注解来指定方法名，语法为@Getter(onMethod_ = {@Accessor("getSubscriptionStatus")})，需根据实际使用的Lombok版本调整。

3. 调整父类方法（若可行） #

如果父类Model的代码可修改，可考虑修改其get_status()方法的名称或返回类型，从根源解决冲突。但如果父类是第三方依赖或不可修改，优先选择前两种方案。
