Answer 1

ExceptionInInitializerError 比较严重的异常在YaopinjibenxinxiImpl.save里加上try{
}catch(Throwable t){
 Throwable a = t.getCause();
 a.printStackTrace();
}
在具体看看是什么错误

Answer 2

YaopinjibenxinxiImpl这个类检查下

Answer 3

catch(Throwable t){ 
Throwable a = t.getCause(); 
a.printStackTrace(); 
} 
加上这个就出现了
这个异常
java.lang.NullPointerException
com.cbd.dao.impl.YaopinjibenxinxiImpl.save(YaopinjibenxinxiImpl.java:37)
com.cbd.domain.impl.YaopinjibenxinxidomainImpl.save(YaopinjibenxinxidomainImpl.java:26)
com.cbd.view.Yaopinxinxi.doPost(Yaopinxinxi.java:66)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

Answer 4

那就是NullPointerException 了，可能你的session这些东西为null了
你调试检查一下

Answer 5

用测试的方法解决了
是Yaopin.hbm.xml的问题

Answer 6

但是整合起来出现了这个异常
java.lang.NoClassDefFoundError: javax/transaction/Synchronization
org.hibernate.impl.SessionImpl.<init>(SessionImpl.java:213)
org.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:471)
org.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:495)
org.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:503)
com.cbd.util.HibernateUtil.getSession(HibernateUtil.java:22)
com.cbd.dao.impl.YaopinjibenxinxiImpl.save(YaopinjibenxinxiImpl.java:32)
com.cbd.domain.impl.YaopinjibenxinxidomainImpl.save(YaopinjibenxinxidomainImpl.java:26)
com.cbd.view.Yaopinxinxi.doPost(Yaopinxinxi.java:69)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)这是怎么回事？？？
