当运行spring微服务项目时，服务器没有启动吗？

Question

在我的项目中，我们使用的是

1. Spring-cloud-loadbalancer，弹簧云网关和Resilience4j.
2. JDK版本1.8
3. IDE - Eclipse氧气.2

当我运行SpringBootApplication的时候，我遇到了错误-

> Exception in thread "main" java.lang.IllegalStateException: Failed to read Class-Path attribute from manifest of jar file:/C:/Users/VaibhavAtray/.m2/repository/org/springframework/boot/spring-boot-actuator/2.1.4.RELEASE/spring-boot-actuator-2.1.4.RELEASE.jar
at org.springframework.boot.devtools.restart.ChangeableUrls.getUrlsFromClassPathOfJarManifestIfPossible(ChangeableUrls.java:132)
at org.springframework.boot.devtools.restart.ChangeableUrls.fromClassLoader(ChangeableUrls.java:98)
at org.springframework.boot.devtools.restart.DefaultRestartInitializer.getUrls(DefaultRestartInitializer.java:92)

Pom.xml看起来像这样-

一切看起来都很好，但应用程序还是没有运行.

Answer 1

您至少需要2.4.X Spring引导，因为SpringCloud2020.0.X至少需要这么多版本才能工作。希望这能成功。
