Question

我试图按照本教程进行操作： https://www.youtube.com/playlist?list=PL4AFF701184976B25

我已经得到了视频5，希望看到hibernate成功添加到我的mysql数据库，但我反而得到了这个错误。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

</hibernate-configuration>

问题是什么，我该如何解决？我无法判断它是否无法找到我的文件，或者其中是否存在语法错误。

另外，如果有人能指出我为Hibernate 4.3.7做一些有用的Hibernate教程，我将非常感激。到目前为止，我发现的所有材料都是破碎/严重过时的材料，需要安装过去的hibernate版本才能学习。

编辑-------------------

我试图在Eclipse中验证，这个错误出现在第8行说＆＃34;根元素类型的文档类型声明＆＃34; hibernate-configuration＆＃34;必须以＆＃39;＆gt;＆＃39;结束。＆＃34;。此外，这条线是＆＃34;连接的唯一线路。＆＃34;不会显示为蓝色，属性名称的名称部分不会显示为紫色。感觉像语法错误，但我似乎无法找到它。 enter image description here

编辑2 ------------------ 这是我的两个文件

UserDetails.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();
    }

}

试试这个：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

       <property name="hibernate.connection.username">root</property>
       <property name="hibernate.connection.password">mysqlroot</property>
       <property name="hibernate.connection.pool_size">1</property>
