java - Spring Boot应用程序中的sessionFactory不会创建

Question

我正在使用 SpringBoot，并且正在尝试连接到 Oracle 数据库。 按照教程，我编写了以下代码，导致以下异常。 我不明白问题出在哪里，在执行factoryBean.afterPropertiesSet();时它崩溃了。

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;
    }

}

异常(exception)情况是:

编辑:

一旦我通过添加缺少的依赖项来纠正崩溃，我仍然无法为 sessionFactory 提供数据。这是类(class):

@Repository
@Transactional
public class ConnectionDAO {

    @Autowired
    private SessionFactory sessionFactory;


    public Customer getCustomer(String name){



        return new Customer("","");
    }

    public Boolean setCustomer(String name, String surname){
        /*
         *
         */
        return false;
    }

}

Answer 1

您缺少:org.thirden.bp.Instant

因此，将此依赖项添加到您的构建中(使用适当的版本进行更新):

<dependency> 
      <groupId>org.threeten</groupId> 
      <artifactId>threetenbp</artifactId> 
      <version>1.3.3</version> 
</dependency>
