[英]Unable to autowire sessionFactory in springboot
請在我的daoImpl
類下面找到。
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應用程序代碼:
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
場景:啟動springboot應用程序時, 無法自動連接sessionFactory
對象。
PS:我知道我可以使用``spring-jpa and
crud倉庫''來代替休眠狀態。 我必須使用休眠模式。 將其視為限制。
錯誤:
說明:com.sagarp.employee.EmployeeDaoImpl中的字段sessionFactory需要找不到類型為'org.hibernate.SessionFactory'的bean。
有人可以幫我一下嗎
如果您想知道Hibernate中低於5.2版本的SessionFactory的代碼
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;
}
