如何在休眠中使用@Qualifier

Question

我的hibernate配置类如下。

@Configuration 
@EnableTransactionManagement 
@ComponentScan({ "com.span.vms.configuration" }) 
@PropertySource(value = { "classpath:application.properties" }) 
public class HibernateConfiguration { 

    @Autowired 
    private Environment environment; 

    @Bean 
    @Primary 
    public LocalSessionFactoryBean sessionFactory() { 
     LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); 
     sessionFactory.setDataSource(dataSource()); 
     sessionFactory.setPackagesToScan(new String[] { "com.span.vms.model" }); 
     sessionFactory.setHibernateProperties(hibernateProperties()); 
     return sessionFactory; 
    } 

    @Bean 
    public LocalSessionFactoryBean sessionFactoryActiviti() { 
     LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); 
     sessionFactory.setDataSource(dataSourceActiviti()); 
     sessionFactory.setPackagesToScan(new String[] { "com.span.vms.model" }); 
     sessionFactory.setHibernateProperties(hibernateProperties()); 
     return sessionFactory; 
    } 

    @Bean(name = "dataSource") 
    public DataSource dataSource() { 
     DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
     dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName")); 
     dataSource.setUrl(environment.getRequiredProperty("jdbc.url")); 
     dataSource.setUsername(environment.getRequiredProperty("jdbc.username")); 
     dataSource.setPassword(environment.getRequiredProperty("jdbc.password")); 
     return dataSource; 
    } 

    @Bean(name = "dataSourceActiviti") 
    public DataSource dataSourceActiviti() { 
     DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
     dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName")); 
     dataSource.setUrl(environment.getRequiredProperty("jdbc.activiti.url")); 
     dataSource.setUsername(environment.getRequiredProperty("jdbc.username")); 
     dataSource.setPassword(environment.getRequiredProperty("jdbc.password")); 
     return dataSource; 
    } 

    private Properties hibernateProperties() { 
     Properties properties = new Properties(); 
     properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect")); 
     properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql")); 
     properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql")); 
     return properties; 
    } 

    @Bean 
    @Autowired 
    public HibernateTransactionManager transactionManager(SessionFactory s) { 
     HibernateTransactionManager txManager = new HibernateTransactionManager(); 
     txManager.setSessionFactory(s); 
     return txManager; 
    } 
} 

当我通过弹簧引导我得到错误说运行此“预期单个匹配的bean，但发现2：数据源和dataSourceActiviti”。

我给每个bean添加了名称。但是如何在这里使用@Qualifier？

您可以通过使用@Primary对其进行注释来制作DataSource主区之一。
