Spring Hibernate исключение после создания сущности

0 голосов
/ 30 октября 2018

У меня есть простая сущность с некоторыми атрибутами, как показано ниже: 

package com.uniba.gliinetti.civicsense.model;

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

@Entity
public class Test {

   @Id
   private String name = null;

   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }
}

Но когда я пытаюсь запустить службу, запускается исключение, как показано ниже: 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister

В чем дело? Что мне не хватает? В том же проекте (это, конечно, более крупный проект) мне пришлось попытаться создать эту сущность, просто чтобы посмотреть, работает ли она. Зависимости те же, что я всегда использую для такого проекта. Любая помощь будет оценена.

Добавьте открытый конструктор по умолчанию в ваш класс сущностей Ваш код станет таким, как показано ниже: 

package com.uniba.gliinetti.civicsense.model;

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

@Entity
public class Test {

    @Id
    private String name = null;

    // Default Constructor
    public Test() {
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Надеюсь, это решит вашу проблему.

использование: - spring.jpa.hibernate.ddl-auto = create-drop Для создания новых сущностей или для обновления используйте spring.jpa.hibernate.ddl-auto = update и убедитесь, что перед запуском создайте схему с именем civicsense. надеюсь, что это сработает. Спасибо
