捕获不到子异常

Question

try {
nf.saveZamNavigation(zamNavigation);
} catch (ConstraintViolationException e) {
statusMessages.add("保存失败！"+e);
return null;
}
可能出现的异常信息是：
22:19:37,141 ERROR [TxPolicy] javax.ejb.EJBTransactionRolledbackException: could not insert: [com.zdsoft.appmanager.navigation.entity.ZamNavigation]; nested exception is org.hibernate.exception.ConstraintViolationException: could not insert: [com.zdsoft.appmanager.navigation.entity.ZamNavigation]
22:19:37,141 SEVERE [application] javax.ejb.EJBTransactionRolledbackException: could not insert: [com.zdsoft.appmanager.navigation.entity.ZamNavigation]; nested exception is org.hibernate.exception.ConstraintViolationException: could not insert: [com.zdsoft.appmanager.navigation.entity.ZamNavigation]

该如何改才能捕获到该异常

Answer 1

catch (ConstraintViolationException e) {
statusMessages.add("保存失败！"+e);
return null;
}
catch(Exception e){
//写你的处理代码就好了
}
再加一个catch块就OK了。试试吧

追问

一下抛出多个异常，所以捕获不到。问题解决了，谢谢

追答

没道理，就算是一次性抛出多个异常它内部也是一个一个的抛，用上述代码肯定上可以捕捉的到的，不知，是如何解决的？

打开主机箱，拔下采集卡，上面一般都有品牌与型号的，在网上搜一下相符的驱动下载待用。
用杀毒软件先清理电脑里面的病毒过后在安装新的驱动。
