我正在開發一個Hibernate項目,並且我配置了一切。在創建休眠配置中的java.lang.ExceptionInInitializerError
因此,我生成了beans和hbm文件。
於是,我寫了一個測試類測試項目(我用的Client
類)
當我執行的代碼,以下異常被拋出:
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.getILoggerFactory(LoggerFactory.java:269)
at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:242)
at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:255)
at org.aness.test.HiberM.<clinit>(HiberM.java:12)
Exception in thread "main"
代碼:
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();
}
}
這就是整個問題。
休眠CFG文件是:*

請發佈您的hibernate.cfg.xml和您的Client.hbm.xml文件。另外,你使用的是哪個Hibernate版本? – Vrushank
你有一個hibernate.cfg.xml文件嗎?你嘗試過不同版本的slf4j嗎? – theMarceloR
