org.hibernate.HibernateException：没有使用 HSQL DB 配置 CurrentSessionContext

Posted 2023-04-19

【中文标题】org.hibernate.HibernateException：没有使用 HSQL DB 配置 CurrentSessionContext

【英文标题】：org.hibernate.HibernateException: No CurrentSessionContext configured with HSQL DB

【发布时间】：2016-11-19 05:01:18

【问题描述】：

我已经为应用程序配置了带有 HSQL 嵌入式 DB 的 Spring Boot。

但我不能使用 sessionFactory.getCurrentSession() 显示没有配置当前会话。

pom 依赖项

数据库配置

@Configuration
@EnableTransactionManagement
public class DatabaseConfig 
    @Bean
    @Primary
    public DataSource dataSource() 
        final SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
        dataSource.setDriver(new org.hsqldb.jdbcDriver());
        dataSource.setUrl("jdbc:hsqldb:db/HSQL_DB/app;shutdown=true");
        dataSource.setUsername("sa");
        dataSource.setPassword("sa");
        return dataSource;
    

    @Bean
    public JpaVendorAdapter jpaVendorAdapter() 
        HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
        jpaVendorAdapter.setGenerateDdl(true);
        jpaVendorAdapter.setShowSql(true);
        jpaVendorAdapter.setDatabasePlatform("org.hibernate.dialect.HSQLDialect");
        return jpaVendorAdapter;
    

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() 
        LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
        lef.setPackagesToScan("com.gvj.samanolsavam.entity");
        lef.setDataSource(dataSource());
        lef.setJpaVendorAdapter(jpaVendorAdapter());
        Properties properties = new Properties();
        properties.setProperty("hibernate.show_sql", "true");
        properties.setProperty("hibernate.jdbc.fetch_size", "100");
        properties.setProperty("hibernate.hbm2ddl.auto", "");
        lef.setJpaProperties(properties);
        return lef;
    


    @Bean  
    public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf)  
        return hemf.getSessionFactory();  
     

我已经自动连接了会话工厂并将这个会话工厂用于当前会话。

@Autowired
    private SessionFactory sessionFactory;

public Session getSession() 
            return sessionFactory.getCurrentSession();
    

例外

【问题讨论】：

你的方法是在@transactional 中调用的？

是的，我已经在服务类级别添加了事务。

【参考方案1】：

用于使用 getCurrentSession 将此 current_session_context_class 添加到您的配置中 如果您不使用自定义配置，则此配置可以，但您会 添加

 properties.setProperty("hibernate.current_session_context_class", "org.springframework.orm.hibernate5.SpringSessionContext");

在 application.yml jpa：

        properties:
            hibernate:
              dialect : org.hibernate.dialect.mysql5Dialect
              show_sql : true
              current_session_context_class:  org.springframework.orm.hibernate5.SpringSessionContext

【讨论】：

properties.setProperty("hibernate.current_session_context_class", "org.springframework.orm.hibernate5.SpringSessionContext");只在 hibernate.current 和它工作之间避免空格
