我已经为应用程序配置了带有 HSQL 嵌入式数据库的 spring boot。

但我无法使用 sessionFactory.getCurrentSession() 显示当前 session 未配置。

pom 依赖

<dependency> 
        <groupId>org.springframework.boot</groupId> 
        <artifactId>spring-boot-starter</artifactId> 
    </dependency> 
    <dependency>

    <dependency> 
        <groupId>org.hsqldb</groupId> 
        <artifactId>hsqldb</artifactId> 
    </dependency> 

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();   
    }  
 
} 

并且我已经自动连接 session 工厂并将该 session 工厂用于当前 session 。

@Autowired 
    private SessionFactory sessionFactory; 
 
public Session getSession() { 
            return sessionFactory.getCurrentSession(); 
    } 

异常

请您参考如下方法:

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，这个配置没问题，但你会 添加

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

在application.yml中 日本语:

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