Class JdbcTemplateMapper<T>

java.lang.Object

org.sfm.jdbc.spring.JdbcTemplateMapper<T>

Type Parameters:

T - the mapped type

All Implemented Interfaces:

org.springframework.jdbc.core.PreparedStatementCallback<List<T>>, org.springframework.jdbc.core.ResultSetExtractor<List<T>>, org.springframework.jdbc.core.RowMapper<T>

public final class JdbcTemplateMapper<T>
extends Object
implements org.springframework.jdbc.core.RowMapper<T>, org.springframework.jdbc.core.PreparedStatementCallback<List<T>>, org.springframework.jdbc.core.ResultSetExtractor<List<T>>

Provide integration point with Spring JdbcTemplate.

It implements RowMapper, PreparedStatementCallback and ResultSetExtractor. Because some JdbcTemplate template signature match against a few of those type you might need to downcast, declare the variable with a specific type or use the type specific method in JdbcTemplateMapperFactory.

class MyDao {
private final JdbcTemplateMapper<DbObject> jdbcMapper =
JdbcTemplateMapperFactory.newInstance().newMapper(DbObject.class);
private final RowMapper<DbObject> rowMapper = jdbcMapper;

public void doSomething() {
List<DbObject> results = template.query(DbHelper.TEST_DB_OBJECT_QUERY, rowMapper);
}

public void doSomethingElse() {
template
.query(TEST_DB_OBJECT_QUERY,
jdbcMapper.newResultSetExtractor((o) -> System.out.println(o.toString())));
}
}
