Declare HibernateException when using Hibernate named query?

[pjydc]

Hi, I have a DAO class that extends Spring's HibernateDaoSupport.
Because Spring's support, the data access methods in this DAO class do not have to
declare any exceptions if I use commands such as

return getHibernateTemplate().find("from Customer");

However, I would like to use Hibernate's named query feature. If I use:

getNamedQuery("example.GetCustomers").list();

I have to explicitly declare HibernateException in method declarations.

I am a bit confused. Spring is well-known for its capability of
translating vendor-specific checked data exceptions into unchecked ones.

I would like to know whether I did something wrong.

Any comment is greatly appreicated!

Pete,

You can use HibernateTemplate.execute() with your own HibernateCallback to interact directly with the Session object but still let Spring take care of your error handling.

Why don't you try:

  List l = getHibernateTemplate().findByNamedQuery("example.GetCustomers");

thanks for your help. the approach:

List l = getHibernateTemplate().findByNamedQuery("example.G etCustomers");

is more elegent and is compatible with Spring's sprit: more application less infrastructure code.

Spring is GOOD!
