Caused by: java.sql.BatchUpdateException: ORA-00001: unique constraint (SI.UK_CN_EN) violated

我们的项目是SSH2
我现在只能捕获到HibernateException：Could not execute JDBC batch update
但是我想要捕获底层异常信息：java.sql.BatchUpdateException: ORA-00001: unique constraint (SI.UK_CN_EN) violated
请问我如何才能捕捉到数据库底层异常
把日志的输出级别改改~~~，你能看到好多东西。
Throwable ct=e,lt=e;
for(;;){ct=ct.getCause();if(ct==null)break;lt=ct;}
底层不要处理异常直接抛
或者捕捉e throw e
或者用e.cause构造异常
