Template Verification Always Throws TemplateNotFoundException #7

Closed fletcherstud closed 1 year ago

fletcherstud commented 1 year ago

The template verification within the renderMustacheTemplate method in the MjmMailBuilder will always throw an exception when the project is packaged as a jar in prod:

2023-06-01 21:55:26 
2023-06-01 21:55:26 dev.ditsche.mailo.exception.TemplateNotFoundException: Template file "./templates/RegistrationConfirmation.mjml" can not be found in classpath
2023-06-01 21:55:26     at dev.ditsche.mailo.factory.MjmlMailBuilder.renderMustacheTemplate(MjmlMailBuilder.java:107) ~[mailo-1.1.3.jar!/:na]
2023-06-01 21:55:26     at dev.ditsche.mailo.factory.MjmlMailBuilder.loadTemplate(MjmlMailBuilder.java:98) ~[mailo-1.1.3.jar!/:na]

Specific Code:

if(ClassLoaderUtil.getResource(templatePath, MjmlMailBuilder.class) == null)
            throw new TemplateNotFoundException("Template file \"" + templatePath + "\" can not be found in classpath");

This is due to the fact that You can't create a File instance, because the only file you have is the JAR. That's why getResource() returns URL. stack overflow

This makes it so it works when ran locally through Intellij. However, it fails when the jar is packaged and ran in a docker container.

I am unsure if you found a way around this when packaging the project as a jar; however, from my research, I think using getResourceAsStream instead of getResource will work.

ditschedev commented 1 year ago

Hey, thanks! I will take a look at it.

ditschedev commented 1 year ago

@fletcherstud I will release a new version later today.

ditschedev commented 1 year ago

Should be resolved by the just release version 1.1.4

fletcherstud commented 1 year ago

Just tried it out in within a docker image and am still getting the same error (Confirmed using 1.1.4 in stacktrace):

I see that you did indeed update it with the change of using getResourceAsStream. I am unsure why this is now failing. Ill let you know if I find anything more

Did you try running it with docker? I am unsure if it is my own build configuration, as running the program locally in intellij does work.

ditschedev commented 1 year ago

I will try it out with docker and packaged later today. If its working locally and your templates folder is included in your resources folder it should be present in the classpath and therefore accessible.

fletcherstud commented 1 year ago

Thanks for your continuous help on this, I too am a little confused on what is happening and I am curious if you run into the same issue

ditschedev commented 1 year ago

@fletcherstud Hey there, I just tested it with a packaged jar and it worked perfectly fine. Though you need to update your path as the default is relative (./templates) which works fine for local development but does not work in a packaged jar where the path needs to be absolute, e.g. /templates. I am trying to take some time the next days to rework the readme and a few lines of code to highlight this for further use cases.

TLDR; Just set the MAILO_TEMPLATE_DIR env to an absolute path when packaged.

fletcherstud commented 1 year ago

Got it working! That makes sense. Thanks for your support!

ditschedev commented 1 year ago

Glad it worked, closing this issue for now.
