Question

请在我的daoImpl类下面找到。

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository
public class EmployeeDaoImpl implements EmployeeDao {

    @Autowired
    private SessionFactory sessionFactory;
    // all my setter  and other methods
}

pom.xml：

我的springBoot应用程序代码：

package com.sagarp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
public class EmployeeHibernateApplication {

    public static void main(String[] args) {
        SpringApplication.run(EmployeeHibernateApplication.class, args);
    }

}

我的application.properties文件：

server.port=8080
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true   

## Spring DATASOURCE (DataSourceAutoConfiguration & DataSourceProperties)
spring.datasource.url = jdbc:mysql://localhost:3306/sagarp?useSSL=false
spring.datasource.username = root
spring.datasource.password = password_123


## Hibernate Properties
# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect

# Hibernate ddl auto (create, create-drop, validate, update)
spring.jpa.hibernate.ddl-auto = update
#spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

场景：当我启动springboot应用程序时，无法自动连接sessionFactory对象。

附注：我知道我可以使用“ spring-jpa and原始存储库”来代替休眠状态。我必须使用休眠模式。将此视为限制。

错误：

说明： com.sagarp.employee.EmployeeDaoImpl中的字段sessionFactory需要一个类型为'org.hibernate.SessionFactory'的bean。

有人可以在这里帮我吗

如果您想了解Hibernate中版本低于5.2的SessionFactory的代码

private static final SessionFactory sessionFactory;
 static {
     try {
         sessionFactory = new Configuration().configure().buildSessionFactory();
     } catch (Throwable ex) {
         System.err.println("Initial SessionFactory creation failed." + ex);
         throw new ExceptionInInitializerError(ex);

     }

 }
 public static SessionFactory getSessionFactory() {
     return sessionFactory;
 }

无法在springboot中自动连接sessionFactory
