Spring Boot应用程序可以独立工作，但在tomcat 7.X中部署时，它不会'；行不通

我是SpringBoot新手，最近创建了一个使用SpringBoot、Neo4j、JSP/Primefaces的应用程序

当我以独立的方式运行它时（使用嵌入的Tomcat容器，它运行良好，没有问题），此时打包是jar

然后我将它切换到War打包，生成War文件并部署到tomcat，它失败了，出现以下异常。我不知道为什么会发生这种错误

尝试过谷歌搜索，有些日子需要在属性文件中提供JDBCURL等，但它的neo4j和url是http://，这不适合这里

对于我来说，解决方案是更新到Tomcat 8。 虽然说任何3.0版的servlet容器都可以，并且说Tomcat 7版支持它，但我无法在上面启动我的war应用程序。

---

但是升级到Tomcat 8解决了这个问题。

首先，你的web.xml不起任何作用，应该删除（在这种情况下，它甚至很危险，因为它将你的应用程序变成servlet 2.5而不是3.0 api版本）。还要确保路径中没有触发数据源创建的任何内容（或者完全禁用

DataSourceAutoConfiguration

。@M.Deinum感谢您指出关于web.xml和3.0 API版本的内容……我已经删除了它。当然，它不能解决问题，但它更好。此外，我还从Main.Java中删除了@EnableAutoConfiguration，它修复了我的tomcat部署问题。现在，我可以从将其应用到tomcat中，部署工作正常，但当我访问.xhtml文件时，它会显示xhtml文件的内容，而不会执行它们。从Web.xml注册facesServlet似乎工作正常，但在我的Spring Boot Java类中一样不工作OK不要删除

@EnableAutoConfiguration

，因为这基本上禁用了Spring我不知道除了删除@EnableAutoConfiguration之外，是否还有其他方法可以禁用DataSourceAutoConfiguration
