Springのエラーについて（Failed to configure a DataSource）

# 初めに
今回はSpringとPostgreSQLの連携でエラーになった場合の対処法に関する記事です。といっても超単純なミスに数日間きづけなかった恥ずかしい記事です。こいつバカだなと思ってみてください。

結論だけ気になる方は以下を参照してください。
[結論](#結論対処法)

# Errorの内容
今回自分は、「__application.properties__」「__application.yml__」にあるDBの設定を読み込めない事象に陥りました。
```:application.yml
spring:
  datasource:
    driver-class-name: org.postgresql.Driver
    url: jdbc:postgresql://db:5432/test
    username: test
    password: test
```
アプリの実行時には以下のようなエラーが出力されました。

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

Action:

Consider the following:
	If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
	If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

上記のエラーが出ている対処法の記事でよくあるのがそもそも「__application.yml__」にDBの設定を記載しましょう。というような内容ばかりで困っていました。

しかも別のプロジェクトで作成すると上手くいったのでなんでこのプロジェクトだけ上手くいかないのか大変困りました。

# 結論（対処法）
結論です・・・ファイル名が間違っていました。
誤：__apprication.yml__
正：__application.yml__
「__l(エル)__」と「__r(アール)__」のスペルを間違えた。
たったこれだけのことです。（なんて恥ずかしいミスなんだ・・・(つω⊂* )）

以上、です。
