传入的执行参数放入一个Map(HashMap<String, String> dataMap)中

/**  EXPORT TEST  */

map.put("db_schema", "md");

map.put("db_user", "root");

map.put("db_password", "root");

map.put("table_name", "inter_log");

map.put("inter_file", "inter_log_20140915.avl");

map.put("delimiter", "|");

map.put("export_limit", "");

代码执行之后,将执行日志以及执行结果也存入该Map中一起返回

dataMap.put("export_status", isOK);

dataMap.put("proc_log", resultMsg.toString());

return dataMap;
