【问题描述】：

我正在尝试使用 Spring Boot 和 Hibernate 创建数据库的代码优先方法。

但是，我还不能这样做。

请建议我如何解决这个问题。

这是我的 POM

这里是 application.properties

spring.datasource.driverClassName = org.postgresql.Driver
spring.datasource.url= jdbc:postgresql://localhost:5432/BookInventory
spring.datasource.username=postgres
spring.datasource.password=root
spring.jpa.database=POSTGRESQL
spring.jpa.show-sql=true
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL94Dialect
spring.jpa.hibernate.ddl-auto=create

这是我的实体

package com.inventory.model;

import javax.persistence.*;

@Entity
public class BookGroup

@Column(name="groupName")
public String getGroupName() 
    return groupName;


public void setGroupName(String groupName) 
    this.groupName = groupName;


@Id
@Column(name="groupId", unique = true)
@GeneratedValue
public int getGroupId() 
    return groupId;


private String groupName;
private int groupId;

这是我的控制器

package com.inventory.controllers;

import com.inventory.model.BookGroup;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import javax.validation.Valid;


@Controller
public class BookGroupController 

BookGroup aBookGroup = new BookGroup();

@RequestMapping(value = "/bookGroupEntry", method = RequestMethod.GET)
public String bookGroupEntryForm(Model model)
    model.addAttribute("bookGroup",aBookGroup); // "bookGroup" ->BookGroup (Class Name)
    return "bookGroupEntry";


@RequestMapping(value = "/showBookGroups", method = RequestMethod.POST )
public String bookGroupSubmit(@ModelAttribute @Valid BookGroup aBookGroup, Model model)

    return "showBookGroups";

【问题讨论】：

***.com/questions/26881739/… 可能不是完全相同的副本，但您应该阅读并翻阅每一块石头。

@Tareq 你有同样的错误吗？异常？

对于初学者来说，你正在混合使用 hibernate 5.1 和 5.2 jars。而且你使用的Spring Boot和Spring版本不支持hibernate 5.2。

【参考方案1】：

我有类似的问题。问题在于错误的属性集。 看看这里：Spring Boot + Hibernate + Postgres - not creating tables
