运行spring-cloud微服务项目，服务器没有启动？

Question

在我的项目中，我们使用的是最新版本的

1. Spring-cloud-loadbalancer、spring-cloud 网关和 Resilience4j。
2. JDK 1.8 版
3. IDE - Eclipse 氧气.2

运行 SpringBootApplication 时，出现以下错误 -

> 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.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

您至少需要 2.4.X Spring 启动，因为 Spring Cloud 2020.0.X 至少需要这么多版本才能工作。 希望这会奏效。
