org.springframework.beans.factory.BeanCreationException：作成中にエラーが発生しまし豆

Question

私は次の詳細を持つ休止状態使用して一緒に日食でSpring MVCのプロジェクトを作成しています：

しかし、私がしよう私はエラーを取得しています "org.springframework.beans.factory.BeanCreationException：名前 'RestController'のBeanを作成中にエラーが発生しました

Answer 1

エラーメッセージは明確である：

No identifier specified for entity: com.ipl.model.UserScore 

あなたのモデルを見ることなく、あなたが指定していないようですあなたのUserScoreエンティティで@Idと注釈が付けられたフィールド。各@Entityには、@Idが必要です。これはデータベースの主キーを表します。

あなたは注釈付きクラスとして UserScoreをマークしている

---

：

<property name="annotatedClasses"> 
    <list> 
     <value>com.ipl.model.UserScore</value> 
    </list> 
    </property> 

そして、これに基づいて：

List userScoreList = session.createCriteria(UserScore.class).list(); 

あなたが休止状態を経由してDBからデータを取得するためにUserScoreを使用している明確ですそれはあなたの意見であるかどうかは関係ありません。休止状態にするにはエンティティでなければなりません。そのBeanに@Entity（xml構成を使用するよりも簡単）の注釈を付ける必要があり、主キーと一致するフィールドを@Idとマークする必要があります。

Marking a POJO as persistent entity

例：あなたがここにあなたの答えを得るでしょう

Spring Hibernate Integration

Answer 2

ユーザを定義しているのでこのようなXMLコンテキストで豆coreDao：同時に

<bean id="UserScoreDao" class="com.ipl.dao.UserScoreDaoImpl"></bean> 

は、UserScoreDaoImplはそこにアプリケーションコンテキスト内の別のUserScoreDao豆になり、名前がuserScoreDaoImplなることを意味している@Componentと注釈されています。

結果として、アプリケーションコンテキストに2つのUserScoreDao Beanがあります。 Springは** UserScoreServiceImpl ** beanに接続する必要があるかどうかを知りません。

たぶん、あなたはそれがコメントでxmlファイル内のBean宣言を削除してみてくださいすることができます

<bean id="persistenceExceptionTranslationPostProcessor" 
     class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /> 

<!--<bean id="UserScoreDao" class="com.ipl.dao.UserScoreDaoImpl"></bean> 
<bean id="UserScoreService" class="com.ipl.services.UserScoreServiceImpl"></bean> 
<bean id="UserScoreDao" class="com.ipl.dao.UserScoreDaoImpl"></bean>
