Jetty 9 + Spring Boot - 由于缺少 ServletWebServerFactory bean，无法

Question

使用Jetty-starter，由于此错误，我无法启动Spring Boot应用程序：

如何解决这个问题？

Answer 1

答案是Spring jetty启动器无法按预期工作，您必须添加依赖项。

删除启动器，然后像这篇文章一样添加它们：https://medium.com/code-your-life/use-jetty9-with-spring-boot-and-gradle-85a1127c919f

dependencies{
compile(“org.springframework.boot:spring-boot-starter-web”) {
exclude module: “spring-boot-starter-tomcat”
}
compile ‘org.eclipse.jetty:jetty-webapp:9.+’
compile ‘org.eclipse.jetty:jetty-jsp:9.+’
}
