每当我尝试运行.war文件时，我都会在此Wiki上学习SpringBoot，它给出了404错误。这是我在系统上创建的文件。

应用程序
package main.java.Application;

}

我所有的Jar都包含Springframework5.0.2和SpringBoot-1.5.9和SpringBoot-AutoConfig-1.5.9，jackson-core和jackson-all，servlet，junit
请帮助我解决此问题。
编辑：
我在控制台上运行以下命令：
$ ant build deploy deploywar reload

最佳答案
Spring Boot旨在作为可执行JAR文件运行（因此public static void main(String[] args)存在。SpringBoot随后将启动嵌入式Web服务器并处理其余部分。如果要部署Spring Boot应用程序，则需要添加一些支持类来实现这一点。请查看说明here.
关于java - Spring Boot应用程序无法正常工作，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/48289652/
