Hibernate erstellt keine Datenbank in PostgreSql Mit Spring Boot

Question

Ich versuche Code ersten Ansatz zum Erstellen von Datenbank mit Spring Boot und Hibernate.

Aber ich kann das noch nicht tun.

Bitte schlagen Sie vor, wie ich das lösen kann.

Hier ist mein POM

Hier ist meine Enity

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; 
} 

ist hier mein Controller

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"; 
} 

}

Ich hatte ähnliches Problem. Das Problem war mit falschen Eigenschaften. Schauen Sie hier: Spring Boot + Hibernate + Postgres - not creating tables
