We oftenCodeRead some resource files (such as video, music, text, etc ). These simple operations are certainly not problematic when running them separately. However, if we compress the code into a jar package, even if we package the resource files together, these things cannot be found. Take a look at the following code: Java code

In maven, by default, the dependent JAR package is not scored into the executable jar package, and if you need to break the dependency into the executable jar package, you need topomadded inmaven-assembly-pluginplug-ins, this is easy to implement, but it is not recommended in the formal development of such use, why? Because a slightly larger project has at least
Sometimes you need to export the j2se project so that it can operate elsewhere, so you don't have to stick to the feeling of development before it can run.The procedure is as follows:Method 1: (export directly when the project does not reference an external jar package)

SSH to the 163 host requires a password, which is inconvenient for some scripts because the password is required, that is, manual intervention is required. The method used previously was to copy the authorized_keys file (I can't remember it, I used it before). Recently, I found a command ssh-copy-ID is very convenient. I tried it and it really worked well. It was recorded below:
