Question

我正在开发一个访问数据库但我遇到一些问题的项目。我尝试使用hibernate 3.2和4.52但它不起作用。

log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" java.lang.NoSuchFieldError: TRACE

    at aucas.Aucas.<init>(Aucas.java:38)
    at aucas.Aucas.main(Aucas.java:45)

例外是这行代码

public Aucas() {
    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Session session = sessionFactory.openSession();
    LoginDialog d = new LoginDialog(null,false,this);
}

您需要在类路径中检查类org.apache.log4j.Level的冲突版本并解决它。 TRACE级别在1.2.12或更高版本的log4j jar中可用。

线程＆＃34; main＆＃34;中的例外情况java.lang.NoSuchFieldError：TRACE
