1.背景 笔者的springboot在一个非root用户环境下运行,这种环境下可以保证不被潜在的jar/开源框架漏洞提权. 比如在防火墙上把外网访问来的443端口映射到本地8443的java web端口.(注意对外服务的80-1024端口需要root权限才能申请), 具体映射方法可参考:Linux下使用iptables配置防火墙端口转发 .由于是受限用户遇到一些问题: org.springframework.web.multipart.MultipartException: Failed to…

SpringBoot注册Windows服务和启动报错的原因 Windows系统启动Java程序会弹出黑窗口.黑窗口有几点不好.首先它不美观:其次容易误点导致程序关闭:但最让我匪夷所思的是:将鼠标光标选中黑窗口日志信息,程序竟然不会继续执行,日志也不会继续输出.从而导致页面一直处于请求状态.回车后程序才能正常执行.同时客户希望我们能部署在Windows系统上并且做到开机自动启动.针对以上需求将系统程序注册成Windows服务变得尤为重要. 针对于SpringBoot程序,目前主流的方法是采用win…
