Das ist meine DAO-Klasse ist

public class Task_Impl implements Task_Interface { 

    @Autowired 
    SessionFactory sessionfactory; 
    @Override 
    @Transactional 
    public void createTask(Task task) { 
     // TODO Auto-generated method stub 
     sessionfactory.getCurrentSession().save(task); 
     System.out.println("Task created in database"); 


    } 

    @Override 
    public void deleteTask() { 
     // TODO Auto-generated method stub 

    } 

} 

Das ist mein Dispatcher Servlet (HelloWeb-servlet.xml)

Wenn ich versuche, das Projekt auszuführen , Erhalte ich den folgenden Fehler

Error creating bean with name 'task_impl_bean': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.hibernate.SessionFactory org.mod.Prime.DAO.Implementation.Task_Impl.sessionfactory; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionfactory' defined in ServletContext resource [/WEB-INF/HelloWeb-servlet.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/util/DTDEntityResolver 

Die Haupt Ursache ist

Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/util/DTDEntityResolver 

Wie Sie in meinem pom-Datei sehen Ich habe die Hibernate-Gläser enthalten. Ich weiß nicht, was genau der Fehler ist. Könnte mir jemand helfen? Vielen Dank im Voraus

Answer 1

Versuchen Sie, die dataSourceBean vor der session

<bean id="dataSourceBean" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="org.postgresql.Driver"/> 
    <property name="url" value="jdbc:postgresql://localhost:5432/newdatabase"/> 
    <property name="username" value="postgres"/> 
    <property name="password" value="P@ssword"/> 
</bean> 

<bean id="sessionfactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="dataSourceBean"></property> 
    <property name="annotatedClasses" value="org.mod.Prime.Data.Task"></property> 
    <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> 
      <prop key="hibernate.show_sql">true</prop> 
     </props> 
    </property> 
</bean> 

Answer 2

Dies ist dynamischer Laden von Klassen während Bean init zu erklären! Die DTD-Entität Resolver wird beim Analysieren der Spring Bean-Klasse beim Laden in den Container verwendet. Ich denke, die Version Ihres Hibernate ist nicht kompatibel mit Ihrem Framework und Code! Warum verwenden Sie eine andere Hibernate-Annotations-Version?

Sind Sie sicher, dass Ihre Hibernate-Version mit Ihrem Spring-Framework kompatibel ist? Versuchen Sie, die Versionen zu ändern, überprüfen Sie auch Ihre JVM-Version, die Sie zum Ausführen des Spring-Servers verwenden!
