#Tomcat #Web #XML

本文介绍了在Tomcat中部署应用后遇到无法启动的问题，并给出了具体的解决办法。问题根源在于web.xml配置错误，通过检查和修正该文件可以解决启动失败的情况。

Tomcat 中 deploy之后无法启动，报错：Application at context path could not be started

原来是web.xml写错了。

以后遇到这个错误先检查web.xml有没有写对

FAIL - Application at context path /ImageAdmincould not be s
FAIL - Application at context path /ImageAdmincould not be started 错误原因

翻译: FAIL - Application at context path /ImageAdmincould could not be started 失败-运行的文本路径/不能被启动. 由此可见,应是路径错误(比如输错了路径)或者context配制文件有错误，还有可能多导入了JAR包。
*************************** APPLICATION FAILED TO START *************************** Description: Web application could not be started as there was no org.springframework.boot.web.servlet.server.ServletWebServerFactory bean defined in the context. Action: Check your application's dependencies for a supported servlet web server. Check the configured web application type.

Jenkins在配置项目时，往往都会指定需要执行的shell命令，我在配置的时候发现其中的执行tomcat的startup.sh脚本时，虽然正常打印了 Tomcat started。 但是在打印该服务的进程时发现并没有这个tomcat的进程信息。 在结合网上的各种解决方案后找到了原因和解决办法，亲测有效： 1、原因： Jenkins在执行shell命令的时候相当于单独开启了一个进程，然后执行完会将这个进程杀掉，所以在配置命令时，一些执行完直接生效且不需要持续运行的命令可以正常调用。 如cp，mv.
