類 SpringHibernateJpaPersistenceProvider 沒有實現請求的接口 PersistenceProvider

Question

我被難住了——我已經好幾年沒用過 Hibernate 了，而且從來沒有用過 Spring Boot。 Spring Boot，但從不使用 Hibernate 或 JPA。 所以我試圖弄清楚如何讓它為我的工作工作 - 我應該在星期一演示一些東西，如果我能讓“這個”工作，我會把它復制到我的工作筆記本電腦上並改變當然是細節。 順便說一句 - 這是我得到的信息 - 我不得不在標題中縮短它：

“類 org.springframework.orm.jpa.vendor.SpringHibernateJpaPersistenceProvider 未實現請求的接口 javax.persistence.spi.PersistenceProvider”

我有“主”類 - 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);
    }
}

，實體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 類（接口只是一種合乎邏輯的方法，但如果你願意，我也會發布它）：

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 端點/MVC 控制器的控制器類：

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 文件在這里只是為了完整性，但我認為這不一定是問題，除非我缺少依賴項：

如果您注意到，我將包含對 Jackson 庫的依賴項，因為書籍列表應作為 JSON 對象返回。 我不認為這是一個問題，而只是說-我可能已經為此刪除了它，但是當它運行時，當/如果它起作用時，我將無法理解書籍清單。 我究竟做錯了什么？？？

Answer 1

將休眠更改為 5.6.9.Final 版本：

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