我正在使用spring4 hibernate entitymanager4工程。我試圖從我的oracle數據庫中自動創建表。Hibernate + JPA不自動在oracle中創建表
但是表格沒有像預期的那樣在db中生成。
這裏是我的pom.xml文件中我堅持

下面是我的persistence.xml，在這裏我配置我的Oracle數據庫
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">
<persistence-unit name="oracDB" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<properties>
<property name="javax.persistence.jdbc.driver" value="oracle.jdbc.OracleDriver" />
<property name="javax.persistence.jdbc.url" value="jdbc:oracle:thin:@localhost:1521:oracDB" />
<property name="javax.persistence.jdbc.user" value="SYSTEM" />
<property name="javax.persistence.jdbc.password" value="password" />
<property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect" />
<property name="hibernate.event.merge.entity_copy_observer"
value="allow" />
</properties>
</persistence-unit>
</persistence>
而且我有一個實體類的用戶，這個實體沒有在我的本地數據庫中創建。
import java.util.Date;
import java.util.Set;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.NamedQuery;
import javax.persistence.OneToMany;
import javax.persistence.OneToOne;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
@Entity
@Table(name = "User")
public class UserEntity {
@Id
@GeneratedValue(generator = "uuid")
@GenericGenerator(name = "uuid", strategy = "uuid2")
@Column(name = "_id")
private String id;
@Column(name = "firstName")
private String firstName;
@Column(name = "lastName")
private String lastName;
@Column(name = "updatedDate")
private Date updatedDate = new Date();
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public Date getUpdatedDate() {
return updatedDate;
}
public void setUpdatedDate(Date updatedDate) {
this.updatedDate = updatedDate;
}
}
我已經hbm2ddl.auto值更改爲update。但沒有結果。
任何人都可以在這裏協助，我失蹤了。
