I believe JdbcTemplate is not designed to work against a Connection as what you expected. As a workaround, if you are fine to create a separate JdbcTemplate for each connection you created, you may wrap your connection in a thin wrapper of DataSource, and feed it to JdbcTemplate.
I think it should work but I haven't tried it anyway...
class SingleConnectionDataSource implements DataSource {
private Connection connection;
public SingleConnectionDataSource(Connection connection) {
this.connection = connection;
}
public Connection getConnection() {
return this.connection;
}
public Connection getConnection(String username, String password) {
return this.connection;
}
}
// at the place you want to use JdbcTemplate
Connection conn = blablabla; // your own way to get it
JdbcTemplate jdbcTemplate = new JdbcTemplate(new SingleConnectionDataSource(conn));
