运行spring云微服务项目时，服务器没有启动

Question

在我的项目中，我们使用最新版本的

1. Spring云负载均衡器、Spring云网关和Resilience4j
2. JDK 1.8版
3. IDE-Eclipse Oxygen。2

在运行SpringBootApplication时，我收到以下错误-

> 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，但应用程序仍然没有运行。。。

Answer 1

由于Spring Cloud 2020.0.X至少需要这么多版本才能工作，因此您至少需要2.4.X Spring引导。希望这能奏效。
