java.lang.ExceptionInInitializerError in the creation of hibernate configuration
提问by a bouchenafa
I'm working on a Hibernate project and I configured everything.
我正在做一个 Hibernate 项目并且我配置了所有东西。
So, I generated the beans and hbm files.
所以，我生成了 beans 和 hbm 文件。
Then, I wrote a test class to test the project(I used the Clientclass)
然后，我写了一个测试类来测试项目（我使用了Client该类）
When I executed the code, the following exception was thrown:
当我执行代码时，抛出了以下异常：
java.lang.ExceptionInInitializerError
Caused by: java.lang.NullPointerException
at org.slf4j.LoggerFactory.singleImplementationSanityCheck(LoggerFactory.java:192)
at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:113)

at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:255)
at org.aness.test.HiberM.<clinit>(HiberM.java:12)
Exception in thread "main"
the code is :
代码是：
import org.aness.beans.*;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class HiberM {
final static Logger logger = LoggerFactory.getLogger(Client.class);
public static void main(String[]arg){
Configuration cfg = new Configuration().configure();
SessionFactory sf =cfg.buildSessionFactory();
Session s = sf.openSession();
Transaction tx =s.beginTransaction();
Client c =new Client();
c.setRaisonSociale("peugeot algerie");
c.setNumeroRc("3215468897");
c.setIdentificationFiscale("888777999");
c.setAdresseActivite("blida zone atlas");
c.setTelephone("00213(0)25436996");
c.setFax("00213(0)25436996");
s.save(c);
tx.commit();
}
}
that's the whole problem.
这就是整个问题。
the hibernate cfg file is : *

I think you've hit this issue.
我想你已经遇到了这个问题。
It seems you're using SLF4J version 1.5.8 (or thereabouts), as the source code of org.slf4j.LoggerFactorywith tag 'SLF4J_1.5.8'has line numbers that match those in your stacktrace.
似乎您正在使用 SLF4J 版本 1.5.8（或相关版本），因为带有标记“SLF4J_1.5.8”的源代码具有org.slf4j.LoggerFactory与堆栈跟踪中的行号匹配的行号。
I would recommend updating to later version of SLF4J.
我建议更新到更高版本的 SLF4J。

Two possibilities :
两种可能性：
Your Hibernate.cfg.xmlis not on classpath. What folder is it in?
你Hibernate.cfg.xml不在类路径上。它在什么文件夹中？
Else you may try updating the version of slf4jjar
否则你可以尝试更新slf4jjar的版本
