我面临的问题是,每个try catch块都被忽略了。
我有这样的结构:
void A(){
// some logic
try{
service.createItem(...);
}catch(Exception e){
System.out.println("blabla...");
}
}
service$createItem(...){
// some logic - building item.
try{
dao.saveItem( item );
}catch(Exception e){
throw new IllegalArgumentException("bla bla");
}
}
dao$saveItem(Item item){
Session session = sessionFactory.getCurrentSession();
session.save(item);
}
项是唯一的,即使我尝试插入重复项,也不会捕获异常并打印“ bla bla”,而是仅打印整个堆栈跟踪信息-就像根本没有处理异常一样。
调试显示它甚至没有跳到A
方法的catch块中,我以前没有遇到过类似的事情,有人遇到过这种情况吗?
什么可能导致问题?
谢谢!

答案 0 :(得分:2)
您无法以这种方式捕获它的原因是,在事务刷新期间而不是在try-catch或save块期间出现异常。
也许考虑在再次保存之前检查数据库中是否存在该记录?
因此,要解决此问题,必须对事务型的类/方法进行尝试捕获,或将事务型移至保存到数据库的类。
