springboot项目打成war包部署到外部tomcat上，排除依赖出现问题

pom文件build模块：

如果带着依赖打包，接口可以正常访问

但把依赖包分离出来就无法访问接口， 但是服务能启动

注释内容:

                    <packagingExcludes>
<!--                        排除依赖包-->
                        WEB-INF/lib/*.jar
                    </packagingExcludes>

项目是启动成功的
但是无法访问接口
对比了一下有依赖的启动日志
发现去除依赖后少了以下两行日志，怀疑是'dispatcherServlet'没有映射接口路径导致， 有遇到过的嘛
