所有已实现的接口:
NamedParameterJdbcOperations
```
public class NamedParameterJdbcTemplate
extends Object
implements NamedParameterJdbcOperations
```
Template class with a basic set of JDBC operations, allowing the use of named parameters rather than traditional '?' placeholders.
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.
