Istvan が言及したように、PreparedStatementCreator が最適です。役立つ場合に備えて実装を貼り付けます..
private final long timeout = 1000; //timeout in seconds
final SqlRowSet rowSet = jdbcTemplate.getJdbcOperations().query(new PreparedStatementCreator() {
@Override
public PreparedStatement createPreparedStatement(Connection con) throws SQLException {
if (timeout>0){
Timer timer = new Timer();
timer.schedule(new ConnectionInterrupter(con), timeout*1000);
}
return con.prepareStatement(queryString);
}
}, new ResultSetExtractor<SqlRowSet>() {
@Override
public SqlRowSet extractData(ResultSet rs) throws SQLException, DataAccessException {
CachedRowSet rowSet = newCachedRowSet();
rowSet.populate(rs);
return new ResultSetWrappingSqlRowSet(rowSet);
}
protected CachedRowSet newCachedRowSet() throws SQLException {
return new CachedRowSetImpl();
}
});
private class ConnectionInterrupter extends TimerTask {
private final Connection connection;
public ConnectionInterrupter(Connection connection) {
this.connection = connection;
}
@Override
public void run() {
try {
logger.warn("Connection timeout has occurred. Manually closing the connection ...");
connection.close();
} catch (SQLException e) {
throw new RuntimeException(e);
}
}
}
