spring JdbcTemplate
Introduction
The JdbcTemplate class executes SQL queries, update statements and stored procedure calls, performs iteration over ResultSets and extraction of returned parameter values. It also catches JDBC exceptions and translates them to the generic, more informative, exception hierarchy defined in the org.springframework.dao package.
Instances of the JdbcTemplate class are threadsafe once configured so it can be safely inject this shared reference into multiple DAOs.
