我有 Java - Spring Boot - Hibernate - Postgres 應用程序。Hibernate 在每次請求時都會創建數據庫連接，為什么？有可配置的嗎？例如，一次會議持續 10 分鐘？我的休眠配置：@Autowiredprivate Environment environment;@Beanpublic LocalSessionFactoryBean sessionFactory() {    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();    sessionFactory.setDataSource(dataSource());    sessionFactory.setPackagesToScan(new String[] { "monitoring" });    sessionFactory.setHibernateProperties(hibernateProperties());    return sessionFactory;}@Beanpublic DataSource dataSource() {    DriverManagerDataSource dataSource = new DriverManagerDataSource();    dataSource.setDriverClassName("org.postgresql.Driver");    dataSource.setUrl(environment.getRequiredProperty("spring.datasource.url"));    dataSource.setUsername(environment.getRequiredProperty("spring.datasource.username"));    dataSource.setPassword(environment.getRequiredProperty("spring.datasource.password"));    return dataSource;}private Properties hibernateProperties() {    Properties properties = new Properties();    properties.put("hibernate.dialect", environment.getRequiredProperty("spring.jpa.properties.hibernate.dialect"));    properties.put("hibernate.show_sql", environment.getRequiredProperty("spring.jpa.hibernate.show-sql"));    properties.put("hibernate.format_sql", "false");    properties.put("hibernate.jdbc.lob.non_contextual_creation", "true");    return properties;}我收到的每個請求都包含以下日志：11:19:13.584 [http-nio-8080-exec-2] DEBUG o.s.j.d.DriverManagerDataSource - Creating new JDBC DriverManager Connection to [jdbc:postgresql://localhost:5432/monit]為什么？我怎樣才能改變它？
