java - 如何修复 my/hibernate.cfg.xml 文件？

Question

我正在尝试遵循本教程: https://www.youtube.com/playlist?list=PL4AFF701184976B25

我已经观看了视频 5，希望看到 hibernate 成功添加到我的 mysql 数据库，但我却收到了此错误。下面是我的 hibernate.cfg.xml 文件。

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

</hibernate-configuration>

问题可能是什么？我该如何解决它？我无法判断它是否找不到我的文件，或者其中是否有语法错误。

另外，如果有人能向我指出一些适用于 Hibernate 4.3.7 的 Hibernate 教程，我将不胜感激。到目前为止，我发现的只是一些损坏/严重过时的 Material 的混合物，需要安装过去版本的 hibernate 才能学习。

编辑--------------------------------

我尝试在 Eclipse 中进行验证，此错误出现在第 8 行: “根元素类型“hibernate-configuration”的文档类型声明必须以“>”结尾。”此外，这一行是唯一一行“连接...”不显示为蓝色，并且属性名称的名称部分不显示为紫色。感觉像是语法错误，但我似乎找不到它。

编辑2------------------ 这是我的两个文件

用户详细信息.java

package org.koushik.javabrains.dto;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class UserDetails {
    @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;
    }
}

HibernateTest.java

package org.koushik.hibernate;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.koushik.javabrains.dto.UserDetails;

public class HibernateTest {

    public static void main(String[] args) {
        UserDetails user = new UserDetails();
        user.setUserId(1);
        user.setUserName("First User");

        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
        Session session = sessionFactory.openSession();
        session.beginTransaction();
        session.save(user);
        session.getTransaction().commit();
    }

}
