springboot直接引入hibernate，用applications.properties當(dāng)配置文件是很簡單的:

spring.application.name=test-hibernate
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=1234
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

然后直接打一個(gè)注解，就可以用hibernate了:

	@PersistenceContext
	private EntityManager mEM;

下面獲取所有的實(shí)體類的名字:

		var emf = mEM.getEntityManagerFactory();
		var model = emf.getMetamodel();
		var ets = model.getEntities();
		for(var et:ets) {
			var s = et.getName();
			System.out.println(s);
		}

但是這種方式下，hibernate.cfg.xml不被加載，總不能所有的配置都在applications.properties里做，hibernate也要有自己的配置文件。deepseek上問了半天，給出的思路，是接替一個(gè)什么factory，我寫了一個(gè)HibernateConfig.java，測試被spring加載了，但是里面的東西好像不生效，因?yàn)槲夜室鈱戝e(cuò)了幾個(gè)字也沒事:

package com.example.hibernate;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;

import javax.sql.DataSource;
import java.util.Properties;

@Configuration
public class HibernateConfig {

    @Autowired
    private DataSource dataSource;

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(dataSource);
        em.setPackagesToScan("com.example.hibernate"); // 掃描實(shí)體類所在的包

        // 使用 Hibernate 作為 JPA 實(shí)現(xiàn)
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);

        // 加載 hibernate.cfg.xml
        Properties properties = new Properties();
        properties.put("hibernate.ejb.cfgfile", "classpath:hibernate.cfg.xml");
        em.setJpaProperties(properties);

        System.out.println("jjjjjj");
        return em;
    }
}

后續(xù)再看把。
