我想配置hibernate 5來在eclipse中訪問oracle 11 g。hibernate 5 oracle11g在eclipse中的配置
的hibernate.cfg.xml如下：
在下面的XML我已經指定的數據庫憑證（URL，用戶名和密碼），dilect，映射類，show_sql。我想問我是否錯過了任何重要的財產。

定義Hello類如表名使用@Entity和用戶ID作爲主鍵使用@Id
Hello.java：
package com.demo.one;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class Hello {
@Id
private int userId;
private String userName;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
} // end of Hello.java
下面的類試圖保存你好的實例中數據庫。
OracleTest.java：
package com.demo.one;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class OracleTest {
public static void main(String[] args) {
Hello z = new Hello();
z.setUserId(2);
z.setUserName("ashish");
SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session session = sf.openSession();
session.beginTransaction();
session.save(z);
session.getTransaction().commit();
}
} // End of OracleTest.java
我試圖挽救Hello類的對象的Oracle 11g XE數據庫（位於我的本地計算機上），OracleTest.java是該寫的。
我收到以下錯誤。
