类 ResultSetExtractor2SqlRowSet

java.lang.Object

online.sanen.unabo.template.ResultSetExtractor2SqlRowSet

所有已实现的接口:

ResultSetExtractor<SqlRowSet>

public class ResultSetExtractor2SqlRowSet
extends Object
implements ResultSetExtractor<SqlRowSet>

Create a SqlRowSet that wraps the given ResultSet, representing its data in a disconnected fashion.

This implementation creates a Spring ResultSetWrappingSqlRowSet instance that wraps a standard JDBC CachedRowSet instance. Can be overridden to use a different implementation.

方法详细资料

extractData

public SqlRowSet extractData(ResultSet rs)
                      throws SQLException

从接口复制的说明: ResultSetExtractor

Implementations must implement this method to process the entire ResultSet.

指定者:

extractData 在接口中 ResultSetExtractor<SqlRowSet>

参数:

rs - ResultSet to extract data from. Implementations should not close this: it will be closed by the calling JdbcTemplate.

返回:

an arbitrary result object, or null if none (the extractor will typically be stateful in the latter case).

抛出:

SQLException - if a SQLException is encountered getting column values or navigating (that is, there's no need to catch SQLException)

createSqlRowSet

protected SqlRowSet createSqlRowSet(ResultSet rs)
                             throws SQLException

Create a SqlRowSet that wraps the given ResultSet, representing its data in a disconnected fashion.

This implementation creates a Spring ResultSetWrappingSqlRowSet instance that wraps a standard JDBC CachedRowSet instance. Can be overridden to use a different implementation.

参数:

rs -

返回:

抛出:

SQLException

newCachedRowSet

protected CachedRowSet newCachedRowSet()
                                throws SQLException

Create a new CachedRowSet instance, to be populated by the createSqlRowSet implementation.

The default implementation uses JDBC 4.1's RowSetProvider when running on JDK 7 or higher, falling back to Sun's com.sun.rowset.CachedRowSetImpl class on older JDKs.

返回:

a new CachedRowSet instance

抛出:

SQLException - if thrown by JDBC methods
