java - Jhipster - JpaRepository "principal.username" @Query - org.springframework.expression.spel.SpelEvaluationException

Question

特定のメソッドでレストコントローラーをテストしているときにエラーが発生しました。注釈を使用@Queryしてデータベースクエリを実行しています。そして、それを行うために「principal.username」を使用しています。アプリケーションでprincipal.usernameがどのように取得され、使用されるかについての全体像はありません。私は現在、それに関する spring-security ドキュメントを見ています。しかし、私の問題はテスト部分にあります。以下のテストを実行すると、@Query.

リポジトリ:

public interface MeetingRepository extends JpaRepository<Meeting,Long> {

  @Query("select m from Meeting m where m.visibility = 'PUBLIC' OR m.user.login = ?#{principal.username}")
  List<Meeting> findOpenAndUserMeetings();

}

レストコントローラメソッド:

@RequestMapping(value = "/api/meetings", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<List<Meeting>> getAll()
{
    List<Meeting> meetings = MeetingRepository.findOpenAndUserMeetings();
    return new ResponseEntity<List<Meeting>>(meetings, HttpStatus.OK);
}

テスト：

@Test
@Transactional
public void getAllMeetings() throws Exception {
    // Initialize the database
    MeetingRepository.saveAndFlush(Meeting);

    // Get all the Meetinges
    restMeetingMockMvc.perform(get("/api/meetings"))
            .andExpect(status().isOk())
            .andExpect(content().contentType(MediaType.APPLICATION_JSON));
}

そして、このエラー:

この「?#{principal.username}」をテストで使用するにはどうすればよいですか? 調査した結果、Spring Security 4.0: WebSocket、Spring Data、および Test Supportが見つかりました。

Spring Data Integration SpEL を使用して Spring Data クエリ内で現在のユーザーにアクセスできるようになりました。Java 構成でこの機能を有効にするには、@Bean を定義します。

@Bean
public SecurityEvaluationContextExtension securityEvaluationContextExtension(){
    return new SecurityEvaluationContextExtension();
}

次に、クエリで Spring Security のプリンシパルを参照できます。例えば：

public interface BlogRepository extends JpaRepository<Blog,Long> {
    @Query("select blog from Blog blog where blog.user.login = ?#{principal.username}")
    List<Blog> findAllForCurrentUser();
}

文脈の問題ですか？
