Я пытаюсь установить связь с моей базой данных MySQL, и Hibernate вставляет таблицу в мою базу данных.Всякий раз, когда я запускаю Apache Tomcat, сервер запускается, но Hibernate SQL не обнаруживается, и моя база данных не заполняется таблицей.
Класс модели:
package com.spring.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
//Hibernate looks for the @Entity and will create a table with the name 'Book'
@Entity(name = "Book")
public class Book {
@Id //Tell hibernate this is a primary key
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String title;
private String author;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
@Override
public String toString() {
return "Book [id=" + id + ", title=" + title + ", author=" + author + "]";
}
}

После запуска Apache я должен увидеть, как Hibernate вставляет таблицу в мою базу данных.
