Spring-Boot Resource Not Found when using executeable Jar

Question

again I face a strange issue and hope someone here can help.

I have a spring boot backend module, what works in eclipse well and application is executeable when sta

Answer 1

Okay, already I found the real problem and the solution.

First, the application use the correct path to the csv files, but there is another issue when using an executable jar what I found under following link. Stackoverflow-Link

Before I come to issue with executable jar I used following solution for getting CSV-File (Issue is getFile()):

final List resourceLines = FileReadUtils.readLines(specialisationResource.getFile());
for (final String line : resourceLines) {
  data.add(getNewTransientSpecialisation(line));
}

But in executeable jar I cant use my resource as file, I need to use it as stream, see provided link above. So I needed to change my code. If you prefer using native java, you can do follows:

final InputStream inputStream = specialisationResource.getInputStream();
final BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));

String line;
while ((line = bufferedReader.readLine()) != null) {
    data.add(getNewTransientSpecialisation(line));
}

I prefer using frameworks and use apache commons like follows:

final List resourceLines = IOUtils.readLines(specialisationResource.getInputStream());
for (final String line : resourceLines) {
    data.add(getNewTransientSpecialisation(line));
}

So just remember, don't use File() for getting resource, always use stream do avoid that issue from beginning :-)

Hope that helps someone.
