SpringHibernateJpaPersistenceProvider 类未实现请求的接口 PersistenceProvider

我很困惑——我已经好几年没有使用过 Hibernate 了，然后就再也没有使用过 Spring Boot。 Spring Boot，但从未与 Hibernate 或 JPA 一起使用。所以我想弄清楚如何让它为我的工作工作 - 我应该在周一演示一些东西，如果我能让“这个”工作，我会将其复制到我的工作笔记本电脑上并更改当然是细节。顺便说一句 - 这是我收到的消息 - 我必须在标题中缩短它：

“类 org.springframework.orm.jpa.vendor.SpringHibernateJpaPersistenceProvider 未实现请求的接口 javax.persistence.spi.PersistenceProvider”

我有“主”类 - TestWebApplication：

package net.draconia.testWeb;

import java.util.Properties;

import javax.sql.DataSource;

import org.apache.commons.dbcp2.BasicDataSource;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.annotation.Bean;
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.JpaVendorAdapter;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.PlatformTransactionManager;

@SpringBootApplication(scanBasePackages = {"com.draconia.testWeb.controller"})
public class TestWebApplication
{
    
    @Bean
    public DataSource getDatasource()
    {
        BasicDataSource objDatasource = new BasicDataSource();
        
        objDatasource.setDriverClassName("com.mysql.jdbc.Driver");
        objDatasource.setUrl("jdbc:mysql://localhost:3306/Test");
        objDatasource.setUsername("root");
        objDatasource.setPassword("R3g1n@ M1lL$ 1$ My Qu3eN!");
        
        return(objDatasource);
    }
    
    @Bean
    public LocalContainerEntityManagerFactoryBean getEntityManagerFactory()
    {
          LocalContainerEntityManagerFactoryBean objEntityManager = new LocalContainerEntityManagerFactoryBean();
          
          objEntityManager.setDataSource(getDatasource());
          objEntityManager.setPackagesToScan(new String[] { "net.draconia.testWeb.beans" });

          JpaVendorAdapter objVendorAdapter = new HibernateJpaVendorAdapter();
          objEntityManager.setJpaVendorAdapter(objVendorAdapter);
          objEntityManager.setJpaProperties(getHibernateProperties());

          return(objEntityManager);
   }
    
    protected Properties getHibernateProperties()
    {
        Properties objHibernateProperties = new Properties();
        
        objHibernateProperties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        objHibernateProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
        
        return(objHibernateProperties);
    }
    
    @Bean
    public JpaTransactionManager getHibernateTransactionManager()
    {
        JpaTransactionManager objTransactionManager = new JpaTransactionManager();
        
        objTransactionManager.setEntityManagerFactory(getEntityManagerFactory().getObject());
        
        return(objTransactionManager);
    }
    
    public static void main(String[] args)
    {
        SpringApplication.run(TestWebApplication.class, args);
    }
}

，实体bean：

package net.draconia.testWeb.beans;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity(name = "Books")
public class Book
{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer miId;
    
    @Column(columnDefinition = "varchar(200) not null", insertable = true, length = 200, name = "BookName", nullable = false, table = "Books", unique = false, updatable = true)
    private String msBookName;
    
    @Column(columnDefinition = "varchar(100) not null", insertable = true, length = 100, name="Author", nullable = false, table = "Books", unique = false, updatable = true)
    private String msAuthor;
    
    public String getAuthor()
    {
        if(msAuthor == null)
            msAuthor = "";
        
        return(msAuthor);
    }
    
    public String getBookName()
    {
        if(msBookName == null)
            msBookName = "";
        
        return(msBookName);
    }
    
    public int getId()
    {
        if(miId == null)
            miId = 0;
        
        return(miId);
    }
    
    public void setAuthor(final String sAuthor)
    {
        if(sAuthor == null)
            msAuthor = "";
        else
            msAuthor = sAuthor;
    }
    
    public void setBookName(final String sBookName)
    {
        if(sBookName == null)
            msBookName = "";
        else
            msBookName = sBookName;
    }
    
    public void setId(final Integer iId)
    {
        if(iId == null)
            miId = 0;
        else
            miId = iId;
    }
}

， DAOConcrete 类（该接口只是一种合乎逻辑的方法，但如果您愿意，我也会发布它）：

package net.draconia.testWeb.dao;

import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Repository;

import net.draconia.testWeb.beans.Book;

@Repository("bookDAO")
public class BookDAOImpl implements BookDAO
{
    @Autowired
    private EntityManagerFactory mObjEntityManagerFactory;
    
    public List<Book> getAllBooks()
    {
        EntityManager objEntityManager = getEntityManagerFactory().createEntityManager();
        List<Book> lstBooks = objEntityManager.createQuery("from Books", Book.class).getResultList();
        
        return(lstBooks);
    }
    
    protected EntityManagerFactory getEntityManagerFactory()
    {
        return(mObjEntityManagerFactory);
    }
}

，以及 REST 端点/MVC 控制器的控制器类：

package net.draconia.testWeb.controllers;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

import net.draconia.testWeb.beans.Book;
import net.draconia.testWeb.dao.BookDAO;

@Controller
public class TestController
{
    @Autowired
    private BookDAO mObjDAO;
    
    @GetMapping("/Books")
    public List<Book> getBooks()
    {
        return(getDAO().getAllBooks());
    }
    
    protected BookDAO getDAO()
    {
        return(mObjDAO);
    }
}

POM 文件放在这里只是为了完整性，但我认为这不一定是问题，除非我缺少依赖项：

如果您注意到，我包含了 Jackson 库的依赖项，因为书籍列表应作为 JSON 对象返回。我不认为这是一个问题，只是说 - 我可能已经为此删除了它，但是当它运行时，当/如果它有效时，书籍列表对我来说将难以理解。我究竟做错了什么？？？

将 hibernate 更改为版本 5.6.9.Final（或任何更高版本 5.6.x）：

<hibernate.version>5.6.9.Final</hibernate.version>
