異なるエンティティ間の関係を正しく確立しようとしています。

コードを見ると、すべて問題なく一貫していると思います (プロパティが Hibernate マッピング構成ファイルで確立されたものと同じ名前であることを確認しました) が、コンパイルされません。したがって、OKではないことは明らかです。表示されるエラーは次のとおりです。

org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'org.springframework.dao.annotation.
PersistenceExceptionTranslationPostProcessor#0' defined in class path

<!-- Profiles. * The build is always executed by selecting at least two
    non-exclusive profiles. By default, such profiles are "dev" and "postgresql"
    (meaning "use PostgreSQL assuming a development environment"). * General
    profiles. There are two general (database-independent) profiles: "dev" and
    "prod". The former is used for development (including testing) and the latter
    is used for production (including testing). As shown below, two dataSources
    (databases schemas) are used in both profiles: one for running (dataSource)
    and another one for the Maven test fase (testDataSource). Note the Maven
    test fase is executed both with development and production profiles. * Database-specific
    profiles. There is a profile for each supported database. * Specific profiles
    can be defined to better adapt to a particular environment by overwriting/adding
    properties and/or including other chunks of valid XML. * Usage: + mvn <<goal>>
    => Execute <<goal>> with default profiles. + mvn -Pdev,<<database>> <<goal>
    => Execute <<goal>> with "dev" and <<database>> profiles. + mvn -Pprod,<<database>>
    <<goal>> => Execute <<goal>> with "prod" and <<database>> profiles. + Note
    that when using -P option all desired profiles must be specified (e.g. "-Pprod"
    with the intention to select "prod" and the default database profile is not
    correct; "-Pprod,<<database>>" must be used instead). * Examples: + mvn <<goal>>
    + mvn -Ppostgresql,prod <<goal>> + mvn -Ppostgresql,dev <<goal>> -->

Java の専門家は、ここで何が起こっているかを確認したり、手がかりを提供したりできますか? 前述のとおり、名前のプロパティを確認しましたが、タイプミスは見当たりません。

ああ、くそ！私は本当に愚かだと感じています。インスタンスのすべてのプロパティを確認したと確信しました。

このバグは、「コメント」と呼ばれるクラスの1つにエラーがあるために発生します。スタックトレースの最新のエラーを読みましたが、スタックトレースを読み続けると、次のことがわかります。

コメントクラスにプロパティ'user'はありません。マッピングとクラスCommentの間に矛盾があります。マッピングはプロパティuserを参照していますが、CommentにはプロパティSetusersがありました。クラスが正しくありません（私は間違った意味で1-Nの関係を作成しました）。

クラスパスに javassist.jar がない場合、このエラーが発生することがあります。私が見たように、あなたはそれを宣言しました。クラス プロパティのすべてのゲッターとセッターがあることを確認します。
