如何从命令行重新加载 Tomcat Java Server 应用程序？

Question

我在重新编译 java servlet 文件后使用Tomcat Web 应用程序管理器重新加载 Tomcat 应用程序，有没有办法使用命令行重新加载应用程序？

Answer 1

I can think of a variety of ways to do this from the command line:

1. Copy the new WAR file to the webapps folder, or just touch it.

2. Use wget or curl to send the appropriate HTTP requests to the server's web management interface.

3. Use the "catalina.sh" script ... if you haven't installed tomcat as a service.

4. Run "/etc/init.d/tomcat restart" ... or however you restart a service on your system.

Note: I (too) have had difficulties in the past getting WAR file redeployment to work. When I'm doing Tomcat development, I tend to go for a full restart rather than redeploying individual servlets / WAR files.

What is WAR file?

I have a project symlink in /var/lib/tomcat7/webapps/app to my app directory and that's it and it work.

Bad idea, for a variety of reasons. But if you insist, then I suggest trying approaches 2, 3 or 4 as described above.
