java - PSQL异常 : Syntax Error near at or "Entity" - Spring Boot

Question

我有一个带有maven的Spring-boot项目，我通过注释将代码与数据库连接起来，所以我不会手动操作数据。我正在使用 Posgresql。

当我尝试访问服务器中的 Url 时，eclipse 控制台向我显示此错误:

org.postgresql.util.PSQLException: ERROR: error de sintaxis en o cerca de «order»

最后是代码:- Controller :

@RestController
@RequestMapping(value="/orders")
public class OrderController {

@Autowired
OrderService orderService;


@RequestMapping(value="/add", method= RequestMethod.POST)
@CrossOrigin(origins = "http://localhost:8100")
public Order addOrder(@RequestBody OrderDTO orderDTO){
    return orderService.addOrUpdateOrder(orderDTO);
}

@RequestMapping(value="/update", method= RequestMethod.PUT)
@CrossOrigin(origins = "http://localhost:8100")
public Order updateOrder(@RequestBody OrderDTO orderDTO){
    //TODO contemplar como va a ser la actualizacion de un pedido
    return orderService.addOrUpdateOrder(orderDTO);
}

@RequestMapping(value="/{idClient}", method= RequestMethod.GET)
@CrossOrigin(origins = "http://localhost:8100")
public List<Order> getOrdersByClient(@PathVariable(value="idClient") Long idClient){
    return orderService.getOrdersByClient(idClient);
}

}

-服务

@Service
@Transactional
public class OrderServiceImpl implements OrderService {

@Autowired
OrderRepository orderRepository;

@Autowired
ClientRepository clientRepository;

@Autowired
TableRestaurantRepository tableRepository;

@Override
public List<Order> getAllOrders() {
    // TODO añadir variables page y size para navegar entre paginas
    return orderRepository.findAll();
}

@Override
public List<Order> getOrdersByClient(Long idClient) {
    // TODO añadir variables page y size para navegar entre paginas
    Client client = clientRepository.findOne(idClient);
    return orderRepository.findByClient(client);
}

@Override
public Order addOrUpdateOrder(OrderDTO orderDTO) {
    // TODO Auto-generated method stub
    Client client = clientRepository.findOne(orderDTO.getIdClient());
    TableRestaurant table = tableRepository.findOne(orderDTO.getIdTable());
    // TODO
    Calendar dateOrder = Calendar.getInstance();
    Order order = new Order(1L, OrderState.SENT, dateOrder, dateOrder, client, table);
    orderRepository.save(order);
    return order;
}

}

-存储库:

public interface OrderRepository extends PagingAndSortingRepository<Order,Long>{

List<Order> findAll();

List<Order> findByClient(Client client);

}

-实体类:

@Entity
@Table
public class Order {

private Long codOrder;
private OrderState state;
private Calendar date;
private Calendar lastUpdate;
private Client client;
private TableRestaurant table;

public Order() {
}

public Order(Long codOrder, OrderState state, Calendar date, Calendar lastUpdate, Client client,
        TableRestaurant table) {

    this.codOrder = codOrder;
    this.state = state;
    this.date = date;
    this.lastUpdate = lastUpdate;
    this.client = client;
    this.table = table;
}

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public Long getCodOrder() {
    return codOrder;
}

public void setCodOrder(Long codOrder) {
    this.codOrder = codOrder;
}

@Enumerated(EnumType.STRING)
public OrderState getState() {
    return state;
}

public void setState(OrderState state) {
    this.state = state;
}

@Temporal(TemporalType.TIMESTAMP)
public Calendar getDate() {
    return date;
}

public void setDate(Calendar date) {
    this.date = date;
}

@Temporal(TemporalType.TIMESTAMP)
public Calendar getLastUpdate() {
    return lastUpdate;
}

public void setLastUpdate(Calendar lastUpdate) {
    this.lastUpdate = lastUpdate;
}

@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "id_client")
public Client getClient() {
    return client;
}

public void setClient(Client client) {
    this.client = client;
}

@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "cod_table")
public TableRestaurant getTable() {
    return table;
}

public void setTable(TableRestaurant table) {
    this.table = table;
}

}

最后是 application.properties:

spring.datasource.url=jdbc\:postgresql\://localhost/restfood
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.max-wait=10000
spring.datasource.max-active=50
spring.jackson.serialization.indent_output=true

我希望有人能对此提供帮助。

Answer 1

我解决了更改 order 名称的问题。在类似的帖子中，Marc B 说:

order is undoubtedly a reserved word. I'll bet you a shiny penny thatif you rename the table to something else, it'll start working.
