Java 为什么在将Spring Boot starter父项目更新到最新的2.2.5.0版本后，在构建Spring Boot项目时会出现此错误？

我是Spring Boot的新手，在更新Spring Boot starter父项目时遇到了一些问题

因此，一开始我有一个pom.xml文件（它工作正常，我可以构建项目，我没有问题）：

我正在获取以下错误消息：

这是从1.x到2.x的主要spring版本升级。在这样的主要版本升级过程中，通常会有一些破坏性的更改，例如包重组、删除不推荐的类/方法等。最好参考某种类型的迁移指南来进行此类升级。您可以参考或其他一些博客，如

Spring提供了一个依赖模块，可以将其添加到pom文件中。此模块分析应用程序并提供所需更改的诊断输出

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-properties-migrator</artifactId>
    <scope>runtime</scope>
</dependency>

SpringBootServletInitializer

现在可从

org.springframework.boot.web.servlet.support

软件包获得
