MySQLSyntaxErrorException：您的SQL語法中有錯誤

Question

我不再看到我在犯我的錯誤的地方。使用Spring 3和Hibernate以及Mysql到目前爲止工作得很好，並且沒問題，但是在這一個上它不起作用。

這是我的課：

@Entity 
@Table(name = "order") 
@XmlRootElement(name = "order") 
public class Order implements java.io.Serializable { 

    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 

    @Id 
    @Column(name = "idOrder", length = 11) 
    private int id; 

    @Column(name = "latitude", nullable = true, length = 45) 
    private String latitude; 

    @Column(name = "longitude", nullable = true, length = 45) 
    private String longitude; 

    @Column(name = "orderDate", length = 30) 
    @DateTimeFormat 
    private Date orderDate; 

    @Column(name = "city", nullable = true, length = 45) 
    private String city; 

    @Column(name = "country", nullable = true, length = 45) 
    private String country; 

    @Column(name = "street", nullable = true, length = 45) 
    private String street; 

    @Column(name = "streetNo", nullable = true, length = 45) 
    private String streetNo; 

    @Column(name = "created", length = 30) 
    @DateTimeFormat 
    private Date created; 

    @JoinColumn(name = "idTaxi") 
    @JoinTable(name= "taxi") 
    @Column(name = "idTaxi", length = 11) 
    private Integer idTaxi; 

    @Column(name = "orderstatus", nullable = false, length = 45) 
    private String orderstatus; 

    @Column(name = "clientname", nullable = true, length = 45) 
    private String clientName; 

    //public getters and setters 

} 

以dB爲單位，我的表名是 「秩序」。我檢查了所有字段的拼寫錯誤。 在持久性XML配置文件：

[...] 
<property name="annotatedClasses"> 
    <list> 
      <value>test.bean.Taxi</value> 
      <value>test.bean.Order</value> 
    </list> 
</property> 
<property name="hibernateProperties"> 
    <props> 
     <prop key="hibernate.dialect"> 
      org.hibernate.dialect.MySQLDialect 
     </prop> 
     <prop key="hibernate.hbm2ddl.auto">create</prop> 
     <prop key="lazy">true</prop> 
     <prop key="hibernate.show_sql">true</prop> 
     <!-- Show and print nice SQL on stdout --> 
     <prop key="hibernate.format_sql">true</prop> 
     <prop key="hibernate.archive.autodetection">class</prop> 
    </props> 
</property> 
</bean> 
[...] 

在DAO類：

public List<Order> showAllOpenOrders() { 

    List<Order> history = new ArrayList<Order>(); 
    history = getHibernateTemplate().find("FROM Order o where o.orderstatus ='open'"); 

    return history; 
} 

我的錯誤：

我已經成功地映射另一個類（出租車），但是這一次..只是不行。我不明白爲什麼......你看到我不喜歡的東西？ 所以我的數據庫表是lowecase「訂單」，並在我的班級順序我映射該表。 但如果我嘗試從數據庫狀態上設置訪問的所有記錄「開放」是這樣的：

public List<Order> showAllOpenOrders() { 
    ; 
    List<Order> history = new ArrayList<Order>(); 
    history = getHibernateTemplate().find("FROM Order o where o.orderstatus ='" + TaxiStatus.OPEN + "'"); 

    return history; 
} 

我收到一個錯誤，有一個SQL例外。

謝謝你的時間。

順序 - 保留關鍵字在MySQL，而且必須是backquoted如果沒有用作order by

重寫的一部分，您的查詢：

history = getHibernateTemplate().find("FROM `Order` o where o.orderstatus ='" + TaxiStatus.OPEN + "'");
