问题描述
我的问题如下:当我在邮递员"应用中创建POST请求时.这就是我尝试发布的内容
My problem is as follows: When i create POST request in "Postman" app. This is what i try to POST
{"name": "John Doe", "email":"jdoe@test.com", "city": "London"}
我遇到以下错误:
{
"timestamp": "2018-11-19T20:16:00.486+0000",
"status": 500,
"error": "Internal Server Error",
"message": "could not read a hi value - you need to populate the table: hibernate_sequence; nested exception is org.hibernate.id.IdentifierGenerationException: could not read a hi value - you need to populate the table: hibernate_sequence",
"path": "/api/ver01/product"
}
我在搜索框中寻找答案,但是没有一个人帮助我.所以我认为问题出在sql代码中,但我不确定.整个项目都使用intelliJ IDE编写.
I was looking for answer in search box but none of them helped me. So i think that the problem is in sql code but I am not sure. Whole project is written in intelliJ IDE.

}
这是我的ProductController类
This is my ProductController class
package com.hubertkulas.webstore.store.controllers;
import com.hubertkulas.webstore.store.archetype.Product;
import com.hubertkulas.webstore.store.jparepository.ProductRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@RestController
@RequestMapping("api/ver01/product")
public class ProductController {
//injecting ProductRepository when ProductController is called
@Autowired
private ProductRepository productRepository;
@GetMapping
public List<Product> list() {
//finds all of the records and returns it
return productRepository.findAll();
}
@PostMapping
@ResponseStatus(HttpStatus.OK)
public void create(@RequestBody Product product){
productRepository.save(product);
}
@GetMapping("/{id}")
public Product get(@PathVariable("id") long id){
// return specific record with added id
return productRepository.getOne(id);
}
}
这是我的ProductRepository界面
This is my ProductRepository Interface
package com.hubertkulas.webstore.store.jparepository;
import com.hubertkulas.webstore.store.archetype.Product;
import org.springframework.data.jpa.repository.JpaRepository;
//Using Jpa for CRUD operations
public interface ProductRepository extends JpaRepository<Product, Long> {
}
这是我的数据库
CREATE TABLE
product
(
id BIGINT NOT NULL,
contact BOOLEAN NOT NULL,
email VARCHAR,
category VARCHAR,
name VARCHAR,
city VARCHAR,
date DATETIME,
price NUMERIC,
model VARCHAR,
PRIMARY KEY (id)
);
CREATE TABLE
hibernate_sequence
(
next_val BIGINT
);
INSERT INTO product (id, contact, email, category, name, city, date, price)
VALUES (1, 1, 'abraham@site.com', 'Electronics', 'Abraham Westbrom', 'New
York', 4419619200000, '3250');
INSERT INTO product (id, contact, email, category, name, city, date, price)
VALUES (2, 1, 'udon@site.com', 'Electronics', 'Udon Hon', 'London',
4419619200000, '799');
INSERT INTO product (id, contact, email, category, name, city, date, price)
VALUES (3, 0, 'mateuszsinus@site.com', 'Software', 'Mateusz Sinus',
'Warsaw', 4419619200000, '10000');
INSERT INTO hibernate_sequence (next_val) VALUES (4);
推荐答案
您的 hibernate_sequence
表是错误的.
请参见 2.6.10.使用标识符表:
create table hibernate_sequences(
sequence_name VARCHAR NOT NULL,
next_val INTEGER NOT NULL
)
