SpringBoot ログイン機能でエラーが表示される

Question

Spring Boot アプリケーションに Spring Security を導入し認証・認可を実装しています。認証はユーザーIDとパスワードを使ったフォーム認証を作成したいのですが,エラーが表示されていて、なぜエラーが出てるのか分からずにいます。IntelliJを使って作成しています。

Answer 1

文字化けしていて、エラーが見えないのですが、おそらくimportエラーです。
（UserController.javaに、UserServiceクラスのimportが無い）

// UserController.java
import com.example.its.domain.auth.UserService; //インポートを追加

public class UserController {
    // UserServiseの「se」を、UserService に変更
    private final UserService userService;

IntelliJ IDEAの文字化けは、メニューの「ヘルプ」>「カスタムVMオプションの編集」に、以下を追加すると直ると思います。

-Dfile.encoding=UTF-8
