Can someone help me to get fix this issue . change Spring Boot version 1.x.x to 2.2.0 migration

Comment From: spencergibb

You should provide your properties files and your configuration properties java object, otherwise it will be difficult to help.

Comment From: htiwari2

ohh sorry spencergibb. Properties I have as string:

factsgather:
  dictionaryPath: /facts/dictionary.yaml

and setter getter have File type - below code:

@ConfigurationProperties(prefix = "factsgather")
@Validated
public class GatherProperties {

    @NotNull
    private File dictionaryPath;

    public File getDictionaryPath() {
        return dictionaryPath;
    }

    public void setDictionaryPath(File dictionaryPath) {
        this.dictionaryPath = dictionaryPath;
    }

}

You are trying to bind /facts/dictionary.yaml to a File. For this to succeed the file must be available directly on the file system but /facts/dictionary.yaml is being found nested inside your jar file. This means that it cannot be treated as a File. You could either remove /facts/dictionary.yaml from your jar file and make it available on the file system, or you could change how you are accessing it. For example GatherProperties.dictionaryPath could be a URL which would allow it to be loaded from a more flexible set of locations.

Thanks wilkinsona but same code working with 1.5.2.RELEASE version is there major change in 2.2.0 ? and can you please elaborate ur example. or any example u have.

Comment From: wilkinsona

Sorry, I can't say why it worked with Spring Boot 1.x as you haven't provided a complete example. Just like 2.x, 1.x cannot load a File from inside a jar so there must be something more to it in 1.x that you haven't shown.

If you'd like us to spend some time investigating that difference, please take the time to provide a complete and minimal sample that works with 1.x and fails with 2.x. You can share such a sample with us by zipping it up and attaching it to this issue or by pushing it to a separate repository on GitHub.

You can read from a URL by using openConnection() and then getInputStream().
