I am not so familiar with the theory of measures which Andre Weil uses to develope the Class Field Theory.  

However, I am interested in learning algebraic number theory and I recently found that the basic ideas of commutative algebra are not so familiar with me:).  

Besides, the fundamental notion of algebraic number theory in Neukirch's book Algebraic number theory is the Minkowski Theory which is quite unclear to me.  

Is there any book except for those of Bourbaki on the topic of commutative algebra and Minkowski theory such that it is friendly to beginners?  

Thank you very much.



Good Minkowski Theory  and Commutative Algebra Books
You might try Pierre Samuel, "Algebraic Number Theory", for a concise introduction with basic treatments of what you are asking about.
