Differences in local development and docker container of spring boot deployment

Local development and docker container of spring boot deployment differences:

1. The difference between file path and file name of the case:

Local development environment for windows operating system, are case insensitive, but case-sensitive container

2. docker within the time zone of the container requires a separate set

And the time difference in the docker GMT 8 hours, so the need to set the time zone, can be modified in the dockerfile, or modify the deployment of yaml file: name: TZ value: Asia / Shanghai

3. Get template file:

After the container of the file under the Resource exists in this jar file inside, on the disk is not the existence of the true path, a path which is actually located inside the jar. Therefore, the method can not obtain the file by ResourceUtils.getFile or this.getClass () getResource ( "") is correct, it can only be obtained in the form of stream:

The correct wording:

InputStream stream = this.getClass().getClassLoader().getResourceAsStream(/template/opinion/33.docx")

or:

ClassPathResource resource = new ClassPathResource("/template/opinion/33.docx");

        // load the template file and replace the agency Opinion data 
        XWPFTemplate Template = XWPFTemplate.compile (resource.getInputStream ())
                .render(model);

4. default within the container does not support Chinese fonts. If you need to print as pdf, then you need to install fonts
