我尝试使用HikariCP池连接,但我无法启动应用程序,因为我得到所有时间,来自create sesion的null对象。
这是我的配置:
系统
HibernateUtil类
public class HibernateUtil {
private static SessionFactory sessionFactory;
private static SessionFactory buildSessionFactory() {
try {
Configuration configuration = new Configuration();
configuration.configure("hibernate.cfg.xml");
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
return sessionFactory;
}
catch (HibernateException ex) {
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
if (sessionFactory == null) {
sessionFactory = buildSessionFactory();
}
return sessionFactory;
}
}
hibernate.cfg.xml中
<?xml version="1.0" encoding="UTF-8"?>

准备使用过滤器构建会话工厂: {} HHH000130:实例化显式连接提供者:org.mariadb.jdbc.MySQLDataSource 应用程序启动方法中的异常
答案 0 :(得分:2)
正如brettw所说,我只需要将提供者类更改为
<prop key="hibernate.connection.provider_class">com.zaxxer.hikari.hibernate.HikariConnectionProvider</prop>
