Question

我已为应用程序配置了HSQL嵌入式数据库的spring boot。

但我无法使用sessionFactory.getCurrentSession()显示当前没有配置会话。

pom依赖

DBCONFIG

@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();  
    } 

}

我已自动连接会话工厂并将此会话工厂用于当前会话。

@Autowired
    private SessionFactory sessionFactory;

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

异常

使用getCurrentSession 将此current_session_context_class添加到您的配置中如果你不使用自定义配置这个配置好，但你会添加

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

在application.yml中

JPA：

        properties:
            hibernate:
              dialect : org.hibernate.dialect.MySQL5Dialect
              show_sql : true
              current_session_context_class:  org.springframework.orm.hibernate5.SpringSessionContext

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