SpringJDBC可以单独使用吗？

Here is a simple query for getting the number of rows in a relation:

int rowCount = this.jdbcTemplate.queryForInt("select count(*) from t_actor");
A simple query using a bind variable:

int countOfActorsNamedJoe = this.jdbcTemplate.queryForInt( "select count(*) from t_actor where first_name = ?", "Joe");
Querying for a String:

String lastName = this.jdbcTemplate.queryForObject( "select last_name from t_actor where id = ?", new Object[]{1212L}, String.class);
Querying and populating a single domain object:

Actor actor = this.jdbcTemplate.queryForObject( "select first_name, last_name from t_actor where id = ?", new Object[]{1212L}, new RowMapper<Actor>() { public Actor mapRow(ResultSet rs, int rowNum) throws SQLException {
                Actor actor = new Actor();
                actor.setFirstName(rs.getString("first_name"));
                actor.setLastName(rs.getString("last_name")); return actor;
            }
        });
Querying and populating a number of domain objects:

List<Actor> actors = this.jdbcTemplate.query( "select first_name, last_name from t_actor", new RowMapper<Actor>() { public Actor mapRow(ResultSet rs, int rowNum) throws SQLException {
                Actor actor = new Actor();
                actor.setFirstName(rs.getString("first_name"));
                actor.setLastName(rs.getString("last_name")); return actor;
            }
        });
