Question

大约一个月前，我还在JDK 1.8和JDK 11上运行eureka-server。最近使用JDK 11，我无法再以Spring-Boot Application的形式启动它。

工作区

Bash个人资料-

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-11.0.2.jdk/Contents/Home

JRE系统库- JAVASE-11（采用OpenJDK 11.0.2 [11.0.2]）

（https://github.com/spring-cloud/spring-cloud-netflix/issues/3391）我遵循了这些规则，并尝试更新pom.xml，但是仍然在启动后，我的localhost:<port>没有显示任何内容。

这是我的POM-

这是我面临的错误-

Answer 1

简短答案：使用兼容的Spring Boot和Spring Cloud版本。

卡姆登（Camden）发行列车was marked end-of-life。 Camden发布系列基于Spring Boot 1.4.x构建，但也已在1.5.x上进行了测试。但是它不支持spring boo 2.x.x版本。

换句话说，您混合了依赖性。

Release Train   Boot Version
----------------------------
Greenwich       2.1.x

Finchley        2.0.x

Edgware         1.5.x

Dalston         1.5.x

Answer 2

我认为您可能需要包括jaxb jar，而Java9之后它们已被弃用

Netflix Eureka Server不能作为JDK 11的Spring-Boot应用程序启动。但JDK1.8仍在运行
