根据Using Tomcat 8上的参考API和这个Deploy Spring Boot Applications教程，应该可以将Tomcat 8与Spring Boot一起使用，它使用Tomcat 7作为默认值 .
出于某种原因，它不适合我 . 我究竟做错了什么？

我已经尝试过这个newer RC version of Spring boot，但仍然加载Tomcat 7而不是8 .
添加 <java.version>1.7</java.version> 属性也没有用 .
尝试了“application.properties” . 端口在启动时设置为指定，但Tomcat的版本仍为默认值7 .
application.properties
server.port=8081
tomcat.version=8.0.3

使用Spring Boot覆盖tomcat并使用
tomcat.version作为属性时，只有在使用spring-boot-starter-parent作为项目的父级时才能使用 .（将版本更改为您喜欢的版本） .
如果您不想将其用作父级，则必须使用pom.xml中的
<dependencyManagement>部分覆盖所有spring版本并保留上述属性 .无论哪种方式都可行，但延伸父母是我最容易说的，但这并不总是可行的 .
你try overriding tomcat.version in your application.properties？具体来说，将其设置为8.0.3会使spring boot运行8.0.3而不是默认值 .
我可以像回答another thread一样回答这个问题 . 我认为有些人不知道Spring Boot的一个关键信息只是模拟实际的Java Servlet容器，如Jetty，Glassfish，Tomcat等 . 您作为开发人员必须选择您将使用的 .
Spring Boot是不错的，但当然有它的垮台，并且实际上只是由spring.io团队创建，以使他们的教程看起来更好，以试图与其他'在几秒钟内启动和运行'技术竞争 .
