我一直在試圖一起使用Spring和Hibernate。目前我正在試圖讓Hibernate自動創建表格。根據我在網上找到的文檔和示例，可通過將hibernate.hbm2ddl.auto設置爲create,create-drop或update來實現。由於某種原因，這是行不通的。下面就是我聲明我的豆子（在\WEB-INF\dispatcher-servlet.xml）：休眠和彈簧 - 數據庫表未被自動創建
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/MY_SHOP" />
<property name="username" value="root" />
<property name="password" value="root" />
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="annotatedClasses">
<list>
<value>com.crimsonwing.dto.UserDTO</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
這是怎麼了，宣佈我的DTO：
@Entity
@Table(name = "USER", uniqueConstraints = @UniqueConstraint(columnNames = { "EMAIL", "UID" }))
public class UserDTO implements Serializable
{
/**
*
*/
private static final long serialVersionUID = 1L;
// Validation Annotation
@Size(min = 8, max = 30, message = "User name must be between 8 and 30 characters long.")
// Database Anotation
@Column(name = "NAME", insertable = true, updatable = true, nullable = false)
private String name;
// Validation Annotation
@NumberFormat(style = Style.NUMBER)
@Min(1)
@Max(99)
// Database Anotation
@Column(name = "AGE", insertable = true, updatable = true, nullable = false)
private int age;
// Validation Annotation
@UniqueEmail
@Email(message = "Email is incorrect format.")
@NotEmpty(message = "Email cannot be left empty")
// Database Anotation
@Column(name = "EMAIL", insertable = true, updatable = true, nullable = false)
private String email;
// Database Anotation
@Id
@Column(name = "UID", insertable = false, updatable = false, nullable = false)
@GeneratedValue()
private String userUID;
public UserDTO(String name, int age, String email)
{
super();
this.name = name;
this.age = age;
this.email = email;
}
public UserDTO()
{
/* WILL BE USED BY HIBERNATE */
}
...
而且這是我正在試圖訪問該數據庫：
@Repository
public class UserDAOImpl implements IUserDAO
{
@Resource
private HibernateTemplate hibernateTemplate;
@Override
public bbolean userExists(String userEmail)
{
UserDTO user = new UserDTO();
user.setEmail(userEmail);
DetachedCriteria detachedCriteria = DetachedCriteria.forClass(user.getClass());
return (this.hibernateTemplate.findByCriteria(detachedCriteria).size() >) ? true : false;
}
...
任何人都可以指出我在正確的方向嗎？有沒有丟失的設置或我做錯了什麼？我在使用spring 3.1和hibernate 3.6.10的Ubuntu x64平臺上使用MySQL版本5.1.58-1ubuntu1。
謝謝。

編輯：
按parasietje的建議，這是導致HQL： Hibernate: select this_.UID as UID2_0_, this_.AGE as AGE2_0_, this_.EMAIL as EMAIL2_0_, this_.NAME as NAME2_0_ from USER this_
我沒有得到任何其他的HQL。如果我沒有記錯的話，當表被創建時，你也會看到生成的HQL語句，這不是在這種情況下發生的事情。
你拼錯「localhost」的... – pap 2012-02-20 14:21:40
@pap：是的，我知道，可惜就是一個錯誤，而粘貼代碼我做了。我已經使更改更新了堆棧跟蹤。 – npinti 2012-02-20 14:23:54
您是否收到任何錯誤？嘗試通過編寫一個將插入數據的方法？這可能會幫助我們調試更多。 – ManuPK 2012-02-20 14:30:51
