Hibernate 调用存储过程

public class ExecuteProceduresDaoImpl extends JdbcDaoSupport implements ExecuteProceduresDao {   
     public Object Call_prLS_OrderByMemberOrNotMember(final String[] parm) {   
	
	
	
	private static String PROC_TEST = "{call PKG_TEST.PRO_TEST(?,?,?)}";
	

	public Boolean cal(final Date date, final String createdCode) throws SQLException {
		return (Boolean) getJdbcTemplate().execute(PROC_TEST, new CallableStatementCallback() {
			public Object doInCallableStatement(CallableStatement stmt)
					throws SQLException, DataAccessException {
				stmt.registerOutParameter(1, OracleTypes.VARCHAR);	
				stmt.setDate(2, new java.sql.Date(date.getTime()));	
				stmt.setString(3, createdCode);	
				stmt.executeQuery();
				String result = stmt.getString(1);
				if (result != null && result.equals("1")) {
					return true;
				}
				return false;
			}
		}); 
	}
