我創建了一個新的Maven項目，我在Eclipse Kepler（包括Hibernate）中安裝了JBoss工具，我想測試一個Hibernate程序，所以我在下面做了這個程序，但是當我作爲Java程序我得到錯誤/例外。如何修復我的第一個Hibernate JAVA程序
這裏是我的文件：
文件SaveStudent.java：
package com.hibernate.demo;
import com.hibernate.entity.student;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class SaveStudent {
public static void main(String[] args) {
SessionFactory f = new Configuration()
.configure("hibernate.cfg.xml")
.addAnnotatedClass(student.class)
.buildSessionFactory();
Session session = f.getCurrentSession();
try {
System.out.println("Creating student...");
student st = new student("X","X","[email protected]");
session.getTransaction();
System.out.println("Saving ...");
session.save(st);
session.getTransaction().commit();
System.out.println("Done!!!");
} finally {
session.close();
f.close();
}
}
}
文件student.java：
package com.hibernate.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="hbstudent")
public class student {
@Id
@Column(name="id")
private int id;
@Column(name="first")
private String firstname;
@Column(name="last")
private String lastname;
@Column(name="email")
private String email;
public student(){
}
public student(String firstname, String lastname, String email) {
this.firstname = firstname;
this.lastname = lastname;
this.email = email;
}
public int getId() {
return id;
}
public void setId(int 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 String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return "student [id=" + id + ", firstname=" + firstname + ", lastname="
+ lastname + ", email=" + email + "]";
}
}
這裏是我的pom.xml：

查找到製作Log4j.properties文件，您將添加到您的類路徑中。 –
根據http://stackoverflow.com/questions/7685510/log4j-warning-while-initializing你可以添加行BasicConfigurator.configure（）;解決你的問題 –
這是因爲你的hibernate依賴關係存在衝突。爲什麼你添加了很多不同版本的相同的依賴關係？ –
