提供一下编译生成的 SysTenantPackageAddBoToSysTenantPackageMapper 类，默认情况下在 target/generated-source 目录下，跟SysTenantPackageAddBo 同一个包

class类的时候是正常的，转化成jdk21的record就报这个错

record 机制兼容性有点问题，注解扩散到底层生成的字段和方法上，也就是相当于在普通的 class 属性和方法上面同时配置了这个注解导致的，我兼容一下

[linpeilie]

可以先通过显式重写getter方法来避免这个问题：

@AutoMapper(target = SysTenantPackage.class, reverseConvertGenerate = false)
public record SysTenantPackageAddBo(

    /*
     * 关联菜单id
     */
    @NotEmpty(message = "关联菜单id不能为空")
    String[] menuIds

) {
    @Override
    @AutoMapping(target = "menuIds", expression = "java(org.apache.commons.lang3.StringUtils.join(source.menuIds(), \",\"))")
    public String[] menuIds() {
        return menuIds;
    }
}
