Question

我有以下配置：

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackageClasses = DemoApplication.class)
public class JpaConfig implements TransactionManagementConfigurer {

    @Value("${dataSource.driverClassName}")
    private String driver;
    @Value("${dataSource.url}")
    private String url;
    @Value("${dataSource.username}")
    private String username;
    @Value("${dataSource.password}")
    private String password;
    @Value("${hibernate.dialect}")
    private String dialect;
    @Value("${hibernate.hbm2ddl.auto}")
    private String hbm2ddlAuto;

    @Bean
    public DataSource configureDataSource() {
        HikariConfig config = new HikariConfig();
        config.setDriverClassName(driver);
        config.setJdbcUrl(url);
        config.setUsername(username);
        config.setPassword(password);

        return new HikariDataSource(config);
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean configureEntityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setDataSource(configureDataSource());
        entityManagerFactoryBean.setPackagesToScan("com.dataart.cashmashine");
        entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());

        Properties jpaProperties = new Properties();
        jpaProperties.put(org.hibernate.cfg.Environment.DIALECT, dialect);
        jpaProperties.put(org.hibernate.cfg.Environment.HBM2DDL_AUTO, hbm2ddlAuto);
        entityManagerFactoryBean.setJpaProperties(jpaProperties);

        return entityManagerFactoryBean;
    }

    @Bean
    public PlatformTransactionManager annotationDrivenTransactionManager() {
        return new JpaTransactionManager();
    }
    @Bean
    public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
        return hemf.getSessionFactory();
    }

}

application.properties：

dataSource.driverClassName=org.postgresql.Driver
dataSource.url=jdbc:postgresql://localhost:5432/cash_mashine
dataSource.username=marc
dataSource.password=marc
hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
hibernate.hbm2ddl.auto=create-drop

在dao中我写下以下行：

@Autowired
private SessionFactory sessionFactory;
@Override
public CreditCard findCard(String cardNumber) {
    Session currentSession = sessionFactory.getCurrentSession();

执行时

sessionFactory.getCurrentSession()

我看到以下错误：

引起：org.hibernate.HibernateException：No CurrentSessionContext 配置！

如何解决这个问题？

Answer 1

尝试在调用DAO的公共服务方法中添加@Transactional。

Answer 2

spring:
    jpa:
        properties:
            hibernate:
                current_session_context_class: org.springframework.orm.hibernate5.SpringSessionContext

application.yml中的

以上配置可以解决这个问题。
