基本的 Spring Boot 应用程序无法正常工作，显示：无法从进程 xxxx 刷新实时数据

我是 Spring Boot 的初学者。我初始化了一个新项目并尝试运行它，但它没有成功运行。当我将其作为 Spring Boot 应用程序运行时，它就会开始执行。在底部编译器/状态栏中，它显示处理和重试。它最多运行 10 次并抛出以下错误：

无法刷新进程 xxxx 的实时数据 https://i.stack.imgur.com/Q7VPO.jpg

我在 STS 中遇到了同样的问题，并尝试了不同的方法来解决它。弹簧致动器的以下依赖性使该问题消失，但是弹簧致动器的要点提供了比这更多的功能。要了解更多信息，请点击https://docs.spring.io/spring-boot/docs/current/reference/html/product-ready-features.html https://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-features.html

应将依赖项添加到您的 pom.xml 文件中

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
