Question

我想连接H2-使用Spring Boot嵌入。我想使用SessionFactory。我知道如何通过applicationContext.xml和dispatcher-servlet.xml使用web.xml

但是，当我从spring initializr开始时，我想使用application.properties配置将数据库与SessionFactory和Session连接起来，但是失败了。它给了我：

需要找不到类型为'org.hibernate.SessionFactory'的bean。

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp


spring.datasource.url=jdbc:h2:~/test
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password= 

spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

spring.jpa.properties.hibernate.current_session_context_class = org.springframework .orm.hibernate5.SpringSessionContext

spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.naming.physical-      
strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.h2.console.enabled=true
spring.h2.console.path=/console

我已经下载了所需的休眠模式。

我只是在搜索sessionFactory配置来连接数据库。

我的pom.xml是这样的：

我的UserDaoImpl：

import com.alpcan.springproject.dao.UserDao;
import com.alpcan.springproject.model.User;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.query.Query;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

@Repository
@Transactional
public class UserDaoImpl implements UserDao {

    @Autowired
    private SessionFactory sessionFactory;

    public List<User> allUsers(){
        Session session = sessionFactory.getCurrentSession();
         Query query = session.createQuery("from User");
        List<User> users=query.list();
        return users;

    }
}

P.S：我可以使用RpaRepository代替SessionFactory吗？有什么区别？会不会有任何速度表现？哪个更好？

如果RpaRepository很强大，我只想使用它。

它真的是您在运行时提供的吗？
