Question

在Java 10中运行我的Spring引导项目并Maven运行一切正常。只需将JDK从10更改为11就会引入以下错误

我没有使用Spring Webflux框架，并且以前不需要任何带有jar的反应堆框架。我知道Java 11从JDK中淘汰了很多JEE内容，但这不是那样。

我尝试了SpringBoot 2.0.5版本和2.1的最新里程碑版本（M4），结果是相同的。我将Spring Cloud版本从Finchley.SR1更改为Greenwich.M1，结果相同。

还有其他人遇到类似的问题吗？任何帮助将不胜感激。

编辑：仅将反应堆堆芯作为托管依赖项添加到我的Pom中会导致另一个问题，即它找不到Netty库...这很奇怪，因为它应该使用tomcat。

在撰写本文时，从Spring Boot文档中，Spring Boot 2.1.0.M4和2.0.5.RELEASE需要Java 8或9和Spring Framework 5.1.0.RELEASE或更高版本。因此，我认为Spring Boot尚未正式支持Java 11。

https://docs.spring.io/spring-boot/docs/2.0.5.RELEASE/reference/html/getting-started-system-requirements.html

https://docs.spring.io/spring-boot/docs/2.1.0.M4/reference/html/getting-started-system-requirements.html

Spring Boot Java 11缺少运行时依赖项
