AnnotationConfiguration實例是必需的

我是在春季和冬眠新。現在我正試圖將一些數據保存到mySql數據庫。但是我收到了一些錯誤。在dispatcher-servelet.xml中是否需要使用hibernate註釋進行配置？我該如何解決這個問題？AnnotationConfiguration實例是必需的

Hibernate配置文件是

的hibernate.cfg.xml

<hibernate-configuration> 
    <session-factory> 
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> 
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> 
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/employee_db</property> 
    <property name="hibernate.connection.username">root</property> 
    <property name="hibernate.connection.password"></property> 
    <property name="connection.pool_size">1</property> 
    <property name="show_sql">true</property> 
    <property name="hbm2ddl.auto">create</property> 

    <mapping class="com.application.domain.Employee" /> 
    </session-factory> 
</hibernate-configuration>

調度員servelet.xml

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p"

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/> 

<!--

for the index controller we are using ParameterizableViewController, so we must 
define an explicit mapping for it. 
--> 
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> 
    <property name="mappings"> 
     <props> 
      <prop key="index.htm">indexController</prop> 
     </props> 
    </property> 
</bean> 

<bean id="viewResolver" 
     class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
     p:prefix="/WEB-INF/jsp/" 
     p:suffix=".jsp" /> 

<bean name="indexController" 
     class="org.springframework.web.servlet.mvc.ParameterizableViewController" 
     p:viewName="index" />

    p:employeeService-ref="employeeService" p:formView="employeeForm" 
    p:successView="employeeSuccess" p:validator-ref="employeeValidator"/> 

</beans>

使用後，從答案 hibernet.cfg.xml新例外1

是否有這個類中的任何問題 EmployeeServiceImpl.java和HibernateUtil.java

public class EmployeeServiceImpl implements EmployeeService { 

@Override 
public void add(Employee employee) { 
//Persist the user object here. 
    Session session = HibernateUtil.getSessionFactory().openSession(); 
    Transaction transaction = null; 
    try { 
     transaction = session.beginTransaction(); 
     session.save(employee); 
     transaction.commit(); 
    } catch (HibernateException e) { 
     transaction.rollback(); 
    } finally { 
     session.close(); 
    } 
    System.out.println("User added successfully"); 
} 
} 

public class HibernateUtil { 
private static final SessionFactory sessionFactory; 
static { 
    try { 
     sessionFactory = new Configuration().configure().buildSessionFactory(); 
    } catch (Throwable ex) { 
     System.err.println("Initial SessionFactory creation failed." + ex); 
     throw new ExceptionInInitializerError(ex); 
    } 
} 
public static SessionFactory getSessionFactory() { 
return sessionFactory; 
} 
}

你有沒有理由不使用Spring來配置會話工廠？ –

需要添加Hibernate的註解罐子，並建立SessionFactory的作爲

return new AnnotationConfiguration().configure().buildSessionFactory();

Take a look

感謝您的重播，但它不起作用。我正在使用SimpleFormController。 – Sudeepta

我已經嘗試過，但它顯示另一個錯誤。我已經添加它在下面我的問題從「回答新Exception1使用hibernet.cfg.xml」後 – Sudeepta

它不起作用。如果你願意，有什麼辦法可以將你的代碼發給你。 – Sudeepta

-1

<bean id="sessionFactory" 
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
     <property name="dataSource" ref="dataSource" /> 
     <property name="configLocation" value="/WEB-INF/hibernate.cfg.xml"></property> 
     <property name="configurationClass">    
      <value>org.hibernate.cfg.AnnotationConfiguration</value>   
     </property> 
     <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">${jdbc.dialect}</prop> 
      <prop key="hibernate.show_sql">${jdbc.showsql}</prop> 
     </props> 
    </property>

你可以使用上面的配置，對我來說工作得很好。
