SpringBootのJUnitで"Failed to load ApplicationContext"エラーが発生する

Question

前提・実現したいこと

SpringBootでバッチアプリケーションを作成し、現在JUnitテストを書いています。
テスト対象のクラスに@Autowiredがあるため、
テストクラスに@SpringBootTestをつけて実行したのですが、エラーが発生してしまいます。
いろいろと調べては試してみているのですが、解決せず…
何かお気づきの点がありましたら、ご教示いただけますと大変ありがたいです。

補足情報

NetBeans使用です。

Answer 1

テスト対象クラスとは無関係なクラス

jp.co.controller.BatchController 

にてSpringが対象クラスをインスタンス化した際に失敗しています。

required a bean of type 'java.lang.String' that could not be found.

とあるように、このControllerに何か余計な実装は残っていませんでしょうか。

BatchController.javaを記載し忘れていたので追記しました。
