Spring Boot 应用程序中的 sessionFactory 不会创建
sessionFactory in SpringBoot application won't create
我正在使用 SpringBoot 并且正在尝试连接到 oracle 数据库。
按照教程，我编写了以下导致以下异常的代码。
在执行 factoryBean.afterPropertiesSet(); 时，我不明白问题出在哪里；它崩溃了。
有什么建议吗？
@Configuration
@ConfigurationProperties("oracle")
@EnableAutoConfiguration(exclude = { //
DataSourceAutoConfiguration.class, //
DataSourceTransactionManagerAutoConfiguration.class, //
HibernateJpaAutoConfiguration.class })
public class BeanFactory_EX{
@Autowired
private Environment env;
@Bean(name = "dataSource")
public DataSource getDataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
// See: application.properties
dataSource.setDriverClassName(env.getProperty("spring.datasource.driver-class-name"));
dataSource.setUrl(env.getProperty("spring.datasource.url"));
dataSource.setUsername(env.getProperty("spring.datasource.username"));
dataSource.setPassword(env.getProperty("spring.datasource.password"));
return dataSource;
}
@Autowired
@Bean(name = "sessionFactory")
public SessionFactory getSessionFactory(DataSource dataSource) throws Exception {
Properties properties = new Properties();
// See: application.properties
properties.put("hibernate.dialect", env.getProperty("spring.jpa.properties.hibernate.dialect"));
properties.put("show_sql", env.getProperty("spring.jpa.show-sql"));
properties.put("current_session_context_class", env.getProperty("spring.jpa.properties.hibernate.current_session_context_class"));
properties.put("hibernate.temp.use_jdbc_metadata_defaults",false);
// Fix Postgres JPA Error:
// Method org.postgresql.jdbc.PgConnection.createClob() is not yet implemented.
LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean();
// Package contain entity classes
factoryBean.setPackagesToScan(new String[] { "" });
factoryBean.setDataSource(dataSource);
factoryBean.setHibernateProperties(properties);
factoryBean.afterPropertiesSet();
//
SessionFactory sf = factoryBean.getObject();
System.out.println("## getSessionFactory: " + sf);
return sf;
}
@Autowired
@Bean(name = "transactionManager")
public HibernateTransactionManager getTransactionManager(SessionFactory sessionFactory) {
HibernateTransactionManager transactionManager = new HibernateTransactionManager(sessionFactory);
return transactionManager;
}
}

在我通过添加缺失的依赖项纠正崩溃后，我仍然无法为 sessionFactory 提供数据。这是 class:
@Repository
@Transactional
public class ConnectionDAO {
@Autowired
private SessionFactory sessionFactory;

public Boolean setCustomer(String name, String surname){
