IllegalArgumentException: 'dataSource' or 'jdbcTemplate' is required when extending JdbcUserDetailsManager?

You've got two beans. One is defined in XML. There's another one being created because you've annotated your class with Repository .

That's the one giving you the trouble because you haven't given it any instructions about wiring the required "'dataSource' or 'jdbcTemplate'". Note in the exception that the bean's name is given as "primeUserDetailsManager". That's the lower-cased simple class name, which is the default name for beans created via component scanning with annotations .

The only way I managed to solve is by defining following in my DAO.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
