SpringBoots使用Hibernate连接数据库。

环境：IDea

springBoot版本：2.1.7

Oracle 11g

中间件：tomcat8（使用8以下的版本在运行程序时会出现一些问题）

项目结构,如图：

springboot 整合 hdfs3 springboot整合hibernate_spring

springboot 整合 hdfs3 springboot整合hibernate_hibernate_02

使用到的jar包列表（要特别注意引用的jar包的版本，博主在整合hibernate时由于引入的jar包版本不合适，出了好多问题。）

springboot 整合 hdfs3 springboot整合hibernate_spring_03

springboot 整合 hdfs3 springboot整合hibernate_springboot 整合 hdfs3_04

        System.out.println(i);
        return "success";
    }
}

}

PersonRepositoryImpl

package com.ssh.respository.impl;



import com.ssh.entity.Person;
import com.ssh.respository.PersonRepository;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

@Repository
public class PersonRepositoryImpl implements PersonRepository {

    @Autowired
    private SessionFactory sessionFactory;

    private Session getCurrentSession() {
        return this.sessionFactory.openSession();
    }

    public Person load(Integer id) {
        return (Person)getCurrentSession().load(Person.class,id);
    }

    public Person get(Integer id) {

        getCurrentSession().delete(person);
    }

    public void flush() {
        getCurrentSession().flush();
    }


}

DomainRepository

package com.ssh.respository;

import java.io.Serializable;
import java.util.List;
public interface DomainRepository<T,PK extends Serializable>{
    T load(PK id);

    T get(PK id);

    List<T> findAll();

    void persist(T entity);

    PK save(T entity);

    void saveOrUpdate(T entity);

    void delete(PK id);

    void flush();
}

PersonRepository

package com.ssh.respository;

import com.ssh.entity.Person;

public interface PersonRepository extends DomainRepository<Person,Integer> 
{
}

ServletInitializer

package com.ssh;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(SshApplication.class);
	}

}

SshApplication

package com.ssh;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SshApplication {

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

}

具体代码是在网上参考一位网友的。

以下是一些资源网站大家下载jar包或者引入依赖时可以参考：

https://mvnrepository.com/artifact/org.hibernate/hibernate-c3p0/5.1.9.Final

https://docs.spring.io/spring-boot/docs/2.1.7.RELEASE/reference/htmlsingle/

http://repo.spring.io/release/org/springframework/spring/

https://www.mvnjar.com/org.hibernate/hibernate-c3p0/5.3.10.Final/detail.html

补充内容：在后来的工作中发现博文中的代码其实不算是一个血统纯正的springBoot整合hibernate
,只能是一个spring MVC的web工程，以下做一些代码上的修改以完善博文。

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!--<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         version="3.1">-->
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

    <!--<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:config/applicationContext.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>-->
</web-app>

web.xml中的内容都注释，不需要要添加，配置文件的内容由程序来加载，不需要由容器加载

springBoot启动类
SpringbootHibernateApplication

package com.springboothibernate;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@ImportResource("classpath:config/applicationContext.xml")
public class SpringbootHibernateApplication {

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

}

由@ImportResource(“classpath:config/applicationContext.xml”)去负责加载配置文件，其他内容不需要改变。
有网友说@ImportResource注解会使拦截器失效，我没有做过测试，如果有结论会另写博文做详细说明。
