Edit your hibernate.reveng.xml file & add the following entry in the <type-mapping> section of the file:-

<sql-type jdbc-type="NVARCHAR" hibernate-type="string"/>

When the Hibernate Generation Wizard will generate the classes for you then it uses hibernate.reveng.xml for type conversion. So when the generator encounter NVARCHAR datatype it check for it's equivalent hibernate data type & convert it into String type.
