public class NamedParameterJdbcTemplate extends java.lang.Object implements NamedParameterJdbcOperations
This class delegates to a wrapped JdbcTemplate
once the substitution from named parameters to JDBC style '?' placeholders is
done at execution time. It also allows for expanding a List
of values to the appropriate number of placeholders.
The underlying JdbcTemplate
is
exposed to allow for convenient access to the traditional
JdbcTemplate
methods.
NOTE: An instance of this class is thread-safe once configured.
