How Do I Correctly Add A Preprocessor?

[aedenj]

With the line,

    ConfigLoaderBuilder.default().addPreprocessor(AwsSecretsManagerPreprocessor()

I've observed that the AwsSecretsManagerPreprocessor would run after the replacement preprocessor. However, my config looks like,

key = "awssm://services/my-service[api-key]",
secret = "awssm://services/my-service[api-secret]",

myConfigString = "myKey=${key} mySecret=${secret};"

And myConfigString doesn't contain the correct key and secret. Instead it contains the strings for key and secret. The only way around this I've found is to copy the contents of the .default() like this,

            return ConfigLoaderBuilder.empty()
                .addPreprocessor(AwsSecretsManagerPreprocessor())
                .addDefaultPreprocessors()
                .addDefaultDecoders()
                .addDefaultParsers()
                .addDefaultParamMappers()
                .addDefaultPropertySources()
                .addResourceSource("....")
                .build()
                .loadConfigOrThrow<MyConfig>()

This doesn't seem quite right. Is there a better way?

Any custom preprocessors will run after the replacement one. What you're doing is the way to define it. Or add the replacement one again after the AwsSecretsManagerPreprocessor
