Java 为什么我要得到这个；org.hibernate.exception.sqlgrammareexception“；在使用SpringDataJPA的SpringBoot项目中？

我在SpringBoot中是一个相当新的人，在尝试在Spring Boot 2.2.5上配置JPA时遇到一些困难。RELEASE连接到mariab数据库的项目

此处是所述项目的Github存储库链接：

我试图详细解释我的情况：

在我的MariaDB服务器中，有一个名为db_test的数据库，其中包含一个名为order的表，并且具有以下结构：

'id',              'bigint(20)',   'NO', 'PRI', NULL,   'auto_increment'
'name',            'varchar(255)', 'NO', '',    NULL,   ''
'address',         'varchar(255)', 'NO', '',    NULL,   ''
'product',         'varchar(255)', 'NO', '',    NULL,   ''
'order_date_time', 'datetime',     'NO', '',    NULL,   ''
'quantity',        'tinyint(4)',   'NO', '',    NULL,   ''

然后我将这个名为Order的模型类映射到上一个表：

@Entity // This tells Hibernate to make a table out of this class
public class Order {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id;

    @Column(name = "name")
    private String fullName;
    private String address;
    private String product;

    @Column(name = "order_date_time")
    private String orderDate;

    private Double quantity;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getFullName() {
        return fullName;
    }

    public void setFullName(String fullName) {
        this.fullName = fullName;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getProduct() {
        return product;
    }

    public void setProduct(String product) {
        this.product = product;
    }

    public String getOrderDate() {
        return orderDate;
    }

    public void setOrderDate(String orderDate) {
        this.orderDate = orderDate;
    }

    public Double getQuantity() {
        return quantity;
    }

    public void setQuantity(Double quantity) {
        this.quantity = quantity;
    }

}

我定义了这个JPAOrderRepository接口，扩展了Crudepository接口：

package com.springboot.excelapi.repository;

import org.springframework.data.repository.CrudRepository;

import com.springboot.excelapi.dto.Order;

public interface OrderRepository extends CrudRepository<Order, Integer> {

}

package com.springboot.excelapi.service;

import java.util.List;

import com.springboot.excelapi.dto.Order;

public interface OrderService {

    public List<Order> getOrdersList();
}

package com.springboot.excelapi.service;

import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.springboot.excelapi.dto.Order;
import com.springboot.excelapi.repository.OrderRepository;

@Service
public class OrderServiceImpl implements OrderService {

    @Autowired
    OrderRepository orderRepository;

    public List<Order> getOrdersList() {

        List<Order> result = (List<Order>) orderRepository.findAll();

        //List<Order> result = new ArrayList<Order>();

        return result;
    }

}

它包含与MariaDB数据库连接和JPA配置相关的信息。目前，ddl auto设置为none，因为我希望避免模型类中的更改不会影响数据库表结构

最后，我有一个JUnit测试类：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { Application.class })
@WebAppConfiguration
@ActiveProfiles(profiles = { "no-liquibase" })
public class ExcelResourceIntegrationTest {

    @Autowired
    OrderServiceImpl orderService;

    @Test
    public void getOrdersListServiceTest() {    
        List<Order> ordersList = orderService.getOrdersList();

        assertThat(ordersList).isNotEmpty();
    }

}

因此，据我所知，Hibernate正在尝试执行以下查询：

select order0_.id as id1_0_, order0_.address as address2_0_, order0_.name as name3_0_, order0_.order_date_time as order_da4_0_, order0_.product as product5_0_, order0_.quantity as quantity6_0_ from order order0_

我觉得这很奇怪：为什么订单0

在stacktrace中，我包含此异常：

您的表名为

order

，这是所有SQL方言中的一个关键字（提示：

orderby

子句）。不要将表命名为order，除非您希望在编写SQL语句时必须始终引用该名称

---

您仍然可以将Java类命名为

Order

，但是您应该将表命名为其他名称，例如

customer\u Order

、

product\u Order

、

Order\u detail

，或者类似的名称。

这很长，我没有复制它，但可能缺少

方言设置？这可能会导致hibernate生成错误的SQL语句（
as
is missing？）参见相关问题，maria DB方言可能与此问题相同
