Tomcat启动springboot项目war包报错：启动子级时出错的问题

今天公司springboot项目准备部署到测试服务器上进行测试，打包好war后放到tomcat里面启动后，前端文件能访问到，但是接口请求一直是404，一直找了很久的原因，tomcat启动是成功的，war打包的时候也提示build success了，tomcat启动日志发现报错：

一直在关注：启动子级时出错，找了很久没有解决！后面关注到下面的zip错误问题，然后再回去考虑打包的问题，终于发现打包的时候出现了问题，虽然最后是build success，但是前面提示了有error没注意到，截图如下：

这就是问题所在，怎么解决的呢？

解决方法：将报错的jar包从maven仓库中删除掉，然后重新下载打包，发现这一次没有报错error，然后扔到tomcat里面启动没有错误日志了，访问也正常了！

谨以此文章记录提醒以后自己多关注一下项目执行、打包等过程和日志等！

总结
