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?
将范围更改为compile
