This article mainly introduces how to solve the problems encountered in the operation of the springboot project into a jar package, which has a certain reference value, and interested friends can refer to it. I hope you can learn a lot after reading this article.

The pit problem at run time after the project is packed into a jar package

A useful piece of code in my springboot project is to add the file get path code to the static directory as follows

String path=ResourceUtils.getURL ("classpath:static/task") .getPath () .replace ("% 20", ")

On the server where Ali Cloud is deployed, when running in the form of jar package, it is found that when running this part of the code, there will be a problem when you get the staic/task path and create the file through the path.

The windows system will report an exception

The linux system will create the acquired directories and folders in the same level directory as jar)

Obviously, none of this is what we want.

Solution.

Keep the original project structure, decompress the jar package and start the project by running the springboot startup class

Extract the jar command:

Jar xvf filename. Jar extracted to the current directory

Run the class command to refer to

Nohup java-cp.: / opt/homework/BOOT-INF/lib/* lemon.homework.HomeworkApplication > / opt/homework/temp.txt

Run class in the background and join the dependent jar package and output the log file to temp.txt:

The interface cannot be found after running the prompt after typing the jar package.

Using the thymeleaf template, put the html file in the templates directory of resources.

Org.springframework.boot spring-boot-starter-thymeleaf

The control layer code is:

@ RequestMapping ("login") public String login (String code, HttpServletResponse response, HashMap map) {logger.debug ("code:" + code); return "/ login";}

There is no problem with eclipse access, and the interface can be accessed normally.

However, after the jar package, the java-jar runtime prompted that the login template could not be found.

It would be nice to remove the "/" from the view name.
