JdbcTemplate调用ORACLE存储过程

List<GridDataBean> gridDataBeans =(List<GridDataBean>) jdbcTemplate.execute(new CallableStatementCreator(){

    @Override
    public CallableStatement createCallableStatement(Connection connection) throws SQLException {
 String spSql = "{call "+sp+"(?,?,?)}";
 CallableStatement callableStatement = connection.prepareCall(spSql);
 callableStatement.setString(1,queryParam.getAccount());
 callableStatement.setString(2,queryParam.getCustomerMnemonic());
 callableStatement.registerOutParameter(3, OracleTypes.CURSOR);
 return callableStatement;
 }
}, new CallableStatementCallback(){

 @Override
 public Object doInCallableStatement(CallableStatement callableStatement) throws SQLException, DataAccessException {
 List<GridDataBean> gridDataBeans = new ArrayList<>();
 callableStatement.execute();
 ResultSet resultSet = (ResultSet) callableStatement.getObject(3); --这个3是呼应上面的3输出数据的
 while(resultSet.next()){
 GridDataBean gridDataBean = new GridDataBean ()
 gridDataBeans.add(gridDataBean );

 }
 return gridDataBeans;
 }
});
return gridDataBeans;
