从 1.4.2.RELEASE 更改为 2.1.7.RELEASE 后 Springboot 项目不起作用 [关闭]

Question

当我将 spring-boot 项目的 pom.xml 版本从 1.4.2.RELEASE 更改为 2.1.7 RELEASE 时，我的问题就来了。

当我使用 2.1.7 RELEASE 时不起作用，另一方面，当我使用 1.4.2.RELEASE 时它工作正常。 1.4.2.发布

 <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.7.RELEASE</version>
</parent>

我使用eclipse IDE进行开发，我已经清理了项目并更新了它，但仍然无法正常工作

我需要使用这个版本，因为我尝试使用 JWT，所以我需要使用 spring boot 2。谢谢

那我该怎么办？

这是我的 pom.xml
