Eclipse Neon，Win 7.我在项目中添加了Tomcat服务器8.5。
我可以去Windows组件服务并手动启动Tomcat服务器，没问题。
当我尝试通过Eclipse项目启动服务器时，我在Eclipse Console窗口中收到此消息：

我能够创建Tomcat服务器并通过Eclipse 启动它，而不用将服务器与我的项目相关联。当我关联项目时，我得到了上述错误。 然后我回去修复项目中的一些配置错误，以便构建，包括在项目属性/项目构面/运行时窗口中添加对Tomcat的正确引用。这可能是我试图解决这个问题的所有其他事情的残留，我不知道。 在修复项目以便构建之后，我能够将项目与Tomcat服务器关联，并且瞧服务器启动并且项目正确执行。这就是我们赚大钱的原因。
