Spring BootでPostgreSQLに接続できない

前提・実現したいこと

PostgreSQL12.8から統計データを取得して表示させたいです。
データベース、ユーザーを作り、A5:SQL Mk-2によりデータをインポートし、
ソースを書いてSTSを実行したところ、以下のエラーメッセージが発生しました。

発生している問題・エラーメッセージ

ネットでログメッセージを調べ、pom.xmlにdependencyを追加、application.propertiesを修正等しましたが、どうやってもPostgreSQLにアクセスしている気配がないため、ご教授お願い致します。

試したこと

JDBCのURLとデータ取得をpsqlで確認しました。

bash
> psql -d 'postgresql://localhost:5432/otnj?user=otnj&sslmode=disable&password=otnj'
psql (12.8)
Type "help" for help.

otnj=> select * from stat;
 id | row  | col |   data
----+------+-----+----------
  1 | 1964 |   1 |   352832
  1 | 1965 |   1 |   366649
  1 | 1966 |   1 |   432937
