Thymeleafは文字列を連結します

私は基本的なSpringBootアプリケーションを持っています。私は2つの値Thymeleafは文字列を連結します

<td class="col_name" th:text="${user.firstName} ${user.lastName}"></td><!-- NAME -->

を連結するテンプレートの1で実行可能なJARファイルとして春初期化子、組み込みのTomcat、Thymeleafのテンプレートエンジン、およびパッケージを使用したが、私は

を含めるこの例外が発生しました例外を解決するには、プラス記号：

<td class="col_name" th:text="${user.firstName} + ${user.lastName}"></td>

それとも、読みやすさのためにスペースを追加したい場合があります。

<td class="col_name" th:text="${user.firstName} + ' ' + ${user.lastName}"></td>
