Question

我在我的dao类中注入一个hibernate sessionfactory bean时遇到问题。说没有豆牌有这个名字

@Repository("emaildao")
public class EmailDAOImpl implements EmailDAO{  

private SessionFactory sessionFactory;

@Autowired
public void setSessionFactory(SessionFactory s){
    sessionFactory = s;
}

@Override
public void saveMessages(List<Message> messages) {
    // some code persisting messages
}

这是我的配置文件

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

@Autowired
private Environment environment;

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

@Bean
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;
}

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"));
    properties.put("hibernate.query_cache", environment.getRequiredProperty("hibernate.query_cache"));
    properties.put("hibernate.query_cache_size", environment.getRequiredProperty("hibernate.query_cache_size"));            
    properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibarnate.hbm2ddl.auto"));
    properties.put("hibernate.connection.CharSet","utf8");
    properties.put("hibernate.connection.characterEncoding","utf8");
    properties.put("hibernate.connection.useUnicode",true);

    return properties;

}

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

代码结构文件夹如下： com.opm.emailheader

应用



道


daoimpl
CONF




HibernateConfiguration.java       AppInitializer.java       WebConfig.java       SecurityConfig.java

异常堆栈跟踪：线程“main”中的异常org.springframework.beans.factory.BeanCreationException：创建名为'emaildao'的bean时出错：注入自动连接的依赖项失败;嵌套异常是org.springframework.beans.factory.BeanCreationException：无法自动装配方法：public void com.opm.emailheader.app.dao.daoimpl.EmailDAOImpl.setSessionFactory（org.hibernate.SessionFactory）;嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有为依赖项找到类型[org.hibernate.SessionFactory]的限定bean：期望至少有一个bean可以作为此依赖项的autowire候选者。依赖注释：{} project structure

无法在dao类中自动装配hibernate SessionFactory
