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，问题就来了。

当我使用2.1.7 RELEASE不起作用时，另一方面，当我使用1.4.2.RELEASE时，它工作正常。 1.4.2发行

 <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对其进行了更新，但仍然无法正常工作

我需要使用此版本，因为我试图使用JWT，所以我需要使用spring boot2。谢谢

那我该怎么办？

这是我的pom.xml
