我尝试升级和降级我的 Java 版本，但它抛出了相同的错误

它在错误消息中告诉您问题是什么。您的 maven 或 gradle 配置中没有适当的库。或者，您需要重新编译，以便从您的配置生成适当的类。

Caused by: java.lang.ClassNotFoundException: org.springframework.http.client.JdkClientHttpRequestFactory

通过快速搜索该包，您需要根据您需要的版本确保您具有以下依赖项

Maven

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>6.2.0</version>
</dependency>
