如何在基于JAVA的spring配置中配置Hibernate Db连接设置

Question

目前我正在将我的bean创建和配置设置从基于JAVA的spring配置基于XML.我坚持移动数据库设置？如何在基于JAVA的配置文件中编写这些hibernate数据库设置？

<bean
    class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="hibernateProperties">
        <value>
            hibernate.connection.driver_class=com.mysql.jdbc.Driver
            hibernate.connection.url=jdbc:mysql://url
            hibernate.connection.username=username
            hibernate.connection.password=password
            hibernate.dialect=org.hibernate.dialect.HSQLDialect
            hibernate.show_sql=false
            </value>

    </property>
    <property name="packagesToScan" value="com.test" />

</bean>


<tx:annotation-driven />

<bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven proxy-target-class="true" />

我添加了交易详情.我得到这个例外:

引起:java.lang.ClassNotFoundException:org.hibernate.context.spi.CurrentSessionContext

这是配置.我还添加了事务管理功能,您将在最终解决方案中明确需要这些功能.

import java.util.Properties;
import javax.sql.DataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource
import org.springframework.orm.hibernate3.HibernateTransactionManager;
import org.springframework.orm.hibernate3.LocalSessionFactoryBean
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
public class DbConfig{

@Bean
public DataSource getDatasource() {

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://url");
        dataSource.setUsername("username");
        dataSource.setPassword("password");

        return dataSource;
    }

@Bean
public SessionFactory getSessionFactory() throws IOException{

LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
 sessionFactoryBean.setPackagesToScan("com.test");

//getHibernateProperties method is a private method 

  sessionFactoryBean.setHibernateProperties(getHibernateProperties());
    sessionFactoryBean.setDataSource(getDatasource());
    sessionFactoryBean.afterPropertiesSet();

    return sessionFactoryBean.getObject();
}

@Bean
    public HibernateTransactionManager getTransactionManager() throws IOException{
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(getSessionFactory());

        return transactionManager;
   }


private static Properties getHibernateProperties() {

        Properties hibernateProperties = new Properties();
        hibernateProperties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
        hibernateProperties.put("hibernate.show_sql", false);
        // other properties

        return hibernateProperties;
    }
