当前使用版本(必填,否则不予处理)
3.3.1.tmp
该问题是如何引起的？(确定最新版也有问题再提!!!)
com.baomidou.mybatisplus.core.handlers.StrictFill的重载方法of，如果fieldVal的实际类型是一个Supplier，也会进入到of(String fieldName, Class<?> fieldType, Object fieldVal) ，导致多包装了一层Supplier
Comment From: miemieYaho
你是怎么用变成这样的?
Comment From: iHearty
@Override
public void insertFill(MetaObject metaObject) {
strictInsertFill(metaObject, "createBy", String.class, () -> auditorAware.getCurrentAuditor().orElse(null));
strictInsertFill(metaObject, "createTime", LocalDateTime.class, LocalDateTime.now());
}

有报错?
Comment From: iHearty
连接中有debug的截图，可以看出来fieldVal类型是一个lambda，实际类型是一个Supplier http://note.youdao.com/noteshare?id=8440c09799106ba50952a21e1bce691e

auditorAware.getCurrentAuditor() 这是个啥? optional?
Comment From: iHearty
是的，是一个optional～
Comment From: miemieYaho
那报错不是很正常嘛,要的是string你却给个optional
Comment From: iHearty
() -> auditorAware.getCurrentAuditor().orElse(null)
auditorAware.getCurrentAuditor()的返回的是个Optional，但是后边我跟了orElse了，所以auditorAware.getCurrentAuditor().orElse(null)的返回值是null或者Object了～
Comment From: miemieYaho
并没有运行报错 https://gitee.com/baomidou/mybatis-plus-samples/blob/master/mybatis-plus-sample-auto-fill-metainfo/src/main/java/com/baomidou/samples/metainfo/handler/MyMetaObjectHandler.java
Comment From: miemieYaho
又看了一下,没办法,你这种就不要用也没必要用Supplier了
Comment From: iHearty
strictInsertFill这个方法，你可以调试追踪下，按理会进入到StrictFill.of的Supplier重载方法中，但其实进入的时of的Object参数的方法～
Comment From: iHearty
又看了一下,没办法,你这种就不要用也没必要用Supplier了
这个“没办法”是指不能重现，还是这个bug修改不了？ 我的程序是没必要用Supplier，但是既然提供了api，那也就得保证api正确吧～
Comment From: miemieYaho
能重现,不过怎么运行那是java说了算的
Comment From: miemieYaho
抱歉,确实重载有问题,
你可以来试用3.3.3.3-SNAPSHOT
仓库地址 https://oss.sonatype.org/content/repositories/snapshots/
入参里 Supplier 和 Class 进行了位置互调
