org.springframework.jdbc.core.SqlRowSetResultSetExtractor
- All Implemented Interfaces:
ResultSetExtractor<SqlRowSet>
ResultSetExtractor
implementation that returns a Spring SqlRowSet
representation for each given ResultSet
.
The default implementation uses a standard JDBC CachedRowSet underneath.

extractData
Description copied from interface:ResultSetExtractor
Implementations must implement this method to process the entire ResultSet.- Specified by:
extractData
in interfaceResultSetExtractor<SqlRowSet>
- Parameters:
rs
- the ResultSet to extract data from. Implementations should not close this: it will be closed by the calling JdbcTemplate.- Returns:
- an arbitrary result object, or
null
if none (the extractor will typically be stateful in the latter case). - Throws:
SQLException
- if an SQLException is encountered getting column values or navigating (that is, there's no need to catch SQLException)
-
createSqlRowSet
Create aSqlRowSet
that wraps the givenResultSet
, representing its data in a disconnected fashion.This implementation creates a Spring
ResultSetWrappingSqlRowSet
instance that wraps a standard JDBCCachedRowSet
instance. Can be overridden to use a different implementation.- Parameters:
rs
- the original ResultSet (connected)- Returns:
- the disconnected SqlRowSet
- Throws:
SQLException
- if thrown by JDBC methods- See Also:
-
newCachedRowSet
Create a newCachedRowSet
instance, to be populated by thecreateSqlRowSet
implementation.The default implementation uses JDBC 4.1's
RowSetFactory
.- Returns:
- a new CachedRowSet instance
- Throws:
SQLException
- if thrown by JDBC methods- See Also:
