如果可以的话，请帮助我。

看来您已经混合了spring版本。就像这里所说的：

您是否已在POM文件中确定spring启动程序父级。详情如下：

此外，此站点对于初始化新的spring项目也很有用：

清楚地显示错误消息：

原因：java.lang.ClassNotFoundException:org.springframework.boot.bind.RelaxedPropertyResolver

。使用的是什么版本的Spring boot？类只在SpringBoot2i中找到，我希望这会有所帮助。4.0.0 org.springframework.boot spring boot starter parent 2.3.3.RELEASE清楚地显示错误消息：
