问题描述
我试图按照本教程进行操作：
https：// www。 youtube.com/playlist?list=PL4AFF701184976B25
我已经看了视频，期待看到hibernate成功添加到我的mysql数据库，但我是反而得到这个错误。
SLF4J：未能加载类org.slf4j.impl.StaticLoggerBinder 。
SLF4J：默认为无操作（NOP）记录器实现
SLF4J：有关详细信息，请参阅http://www.slf4j.org/codes.html#StaticLoggerBinder。

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，如果有人可以指出，我会非常感激我朝着一些为Hibernate 4.3.7工作的Hibernate教程。到目前为止，我发现的所有内容都是混合了大量过期的材料，需要安装过去的hibernate版本才能学习。
编辑------ -------------
我试图在Eclipse中进行验证，此错误出现在第8行，表示
文档类型根元素类型hibernate-configuration的声明必须以'>'结尾。此外，此行是连接...不以蓝色显示的唯一行，并且属性名称的名称部分不以紫色显示。感觉像一个语法错误，但我似乎无法找到它。

这里是我的两个文件
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;
$ / code> HibernateTest.java
package org.koushik.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
导入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（）;
}
}
解决方案
试试这个：
<？xml version =1.0encoding =utf-8？>
<！DOCTYPE hibernate-configuration PUBLIC

I'm attempting to follow this tutorial: https://www.youtube.com/playlist?list=PL4AFF701184976B25
I've gotten to video five expecting to see hibernate successfully adding to my mysql database, but I'm instead getting this error. Below that is my hibernate.cfg.xml file.
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.

What could the problem be and how can I go about fixing it? I can't tell if it can't find my file, or if something is syntactically wrong within it.
Also, I'd be very grateful if someone could point me towards some working Hibernate tutorials for Hibernate 4.3.7. All I've found so far is a mixture of broken/heavily out dated materials that require installing past versions of hibernate to learn from.
Edit-------------------
I attempted to validate in Eclipse and this error appears at line 8 saying "The document type declaration for root element type "hibernate-configuration" must end with '>'." Also, this line is the only line where the "connection..." doesn't appear in blue, and the name part of property name doesn't appear in purple. Feels like a syntax error but I can't seem to find it.
Edit 2------------------ Here are my two files
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();
}
}
解决方案
Try this:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
