１．得到系統的類型．不同的系統有不同的文件分割符號．

public static boolean isLinux(){
??? ?String OS = System.getProperty("os.name").toLowerCase();
??????? if (OS.indexOf("windows") > -1) {
??????? ?return false;
??????? }
??????? else{
??????? ?return true;
??????? }
??? }?

?

２．根據不同的系統生成不同的命令：

／／表名

?String dbs = "ACTION DDINFO DEVICE DEVICEALARM DEVICEINFO DEVICELOG ＂；

List command=new ArrayList();

?if (isLinux) {
??????????????? command.add(exec_path+ "mysqldump");
??????????????? command.add("--opt");
??????????????? command.add("--user=root");
??????????????? command.add("--lock-all-tables=true");
??????????????? command.add("--result-file=" + dumpedFilepath+File.separator+SERVER_BACKUP_SQL_FILE);
??????????????? command.add("orca");
??????????????? String[] str=dbs.split(" ");
??????????????? for(int i=0;i<str.length;i++)
??????????????? command.add(str[i]);??
??????????? }
??????????? else {
??????????????? command.add("\""+exec_path+ "mysqldump\"");// is this work?
??????????????? command.add("--opt");
??????????????? command.add("--user=root");
??????????????? command.add("--lock-all-tables=true");
??????????????? command.add("--result-file=" + dumpedFilepath+File.separator+SERVER_BACKUP_SQL_FILE);
??????????????? command.add("orca");
??????????????? String[] str=dbs.split(" ");
??????????????? for(int i=0;i<str.length;i++)
??????????????? command.add(str[i]);

３．運行命令

得到Runtime

private Runtime cmd = Runtime.getRuntime();

Process p = cmd.exec((String[])command.toArray(new String[0]),null);
??????? ?String line;
??????????? BufferedReader br=new BufferedReader(new InputStreamReader(p.getErrorStream()));
??????????? while ( (line = br.readLine()) != null)
??????????????? log.error("<<<<<<<" + line);

?

Process 是為了顯示錯誤信息
