Java, Spring: Testing DAOs for DataAccessException with Mockito

I'm trying to increase my test coverage so I'm wondering, how would you go about testing for DataAccessExceptions being thrown in a DAO, for example in a simple findAll method which just returns all the data from your data source? In my case, I'm using Spring JdbcTemplates.

For general testing I have my setUp-method with an @Before annotation, mocking the jdbcTemplate used, setting it up in the DAO and mocking all jdbc calls. Now forcing a DataAccessException for something like a create method is pretty simple, just throw the exception when calling a create statement with the right primary keys.

However, I really have no idea how to handle this for methods like simple findAll methods which don't take any input parameters. Testing the valid implementation is straight forward, but how would you go about mocking having no DB connection without it affecting every other test or method?
