java.lang.NoClassDefFoundError: org/apache/commons/pool2/PooledObjectFactory

Question

Я новичок в Spring. Я использую BasicDataSource

<bean id="myDataSource" class="org.apache.commons.dbcp2.BasicDataSource"> 
     <property name="driverClassName" value="com.mysql.jdbc.Driver"/> 
     <property name="url" value="jdbc:mysql://localhost:3306/MySQL"/> 
     <property name="username" value="root"/> 
     <property name="password" value="Root"/> 
    </bean> 

    <bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="myDataSource"/> 
    <property name="mappingResources"> 
     <list> 
     <value>com/test/jdbcTemplate/employee.hbm.xml</value> 
     </list> 
    </property> 
    <property name="hibernateProperties"> 
     <props> 
     <prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect</prop> 
     <prop key="hibernate.current_session_context_class">thread</prop> 
     <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop> 
     <prop key="hibernate.show_sql">yes</prop> 
     </props> 
    </property> 
    </bean> 

Я использовал Hibernate-Викисклад аннотации-3.0.0.ga.jar, Викисклад pool2-2.0.jar, Викисклад dbcp2-2.1.jar, MySQL-разъем-Java -5.1.4.jar, спящий режим-ядро-3.6.9.Final.jar.

Я получаю эту ошибку:

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeHibernateTemplateImpl' defined in class path resource [com/test/jdbcTemplate/EmployeeBean.xml]: Cannot resolve reference to bean 'hibernateTemplate' while setting bean property 'hibernateTemplate'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateTemplate' defined in class path resource [com/test/jdbcTemplate/EmployeeBean.xml]: Cannot resolve reference to bean 'mySessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in class path resource [com/test/jdbcTemplate/EmployeeBean.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/annotations/common/reflection/MetadataProvider

Я думаю, вы пропустили эту библиотеку https://commons.apache.org/proper/commons-pool/download_pool.cgi
