我想从我的swing应用程序导出数据库tp进行备份 我正在谷歌上搜索,与我合作的唯一方法就是:

FileWriter fw = null;                   

String path="C:/Users/mypc/Desktop/tesst/back.sql";
String dumpCommand ="mysqldump -u root --password= gestiondestock > "+path;
// Runtime.getRuntime().exec("mysqldump -u root --password= gestiondestock > "+path);
File data = new File(path);

try{
    fw = new FileWriter(data);
    fw.close();
}catch(IOException ex){
    ex.printStackTrace();
}

Runtime rt = Runtime.getRuntime();

try {
    Process proc = rt.exec(dumpCommand);
    InputStream in = proc.getInputStream();
    InputStreamReader read = new InputStreamReader(in,"latin1");
    BufferedReader br = new BufferedReader(read);
    BufferedWriter bw = new BufferedWriter(new FileWriter(data,true));
    String line=null;
    StringBuffer buffer = new StringBuffer();

    while ((line=br.readLine())!=null){
        buffer.append(line+"\n");
    }
    String toWrite = buffer.toString();
    bw.write(toWrite);
    bw.close();
    br.close();
} catch (IOException e) {
    e.printStackTrace();
}

但我只得到日期基础信息而不是创建表并插入....

我只收到这些信息:

- MySQL转储10.10

- 主持人:localhost数据库:gestiondestock


- 服务器版本5.1.36-community-log

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40103 SET @OLD_TIME_ZONE=@@TIME_ZONE */;
/*!40103 SET TIME_ZONE='+00:00' */;
/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS,    FOREIGN_KEY_CHECKS=0 */;
  /*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
   /*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;

如何修复并获取sql文件的所有信息??,当我尝试在phpmyadmin上导出时,我获取所有信息

dumpCommand可以从cmd框中手动完成

以及导入它的最佳方法!!


解决方案

我不能在不运行shell的情况下进行重定向,我上面没有这样做。 所以我必须这样做:

 String path="C:/Users/mypc/Desktop/tesst/back.sql";
 String dumpCommand = "mysqldump -u root gestiondestock --result-file="+path;

- result-file =“+ path

1 个答案:

答案 0 :(得分:0)

mysqldump命令似乎有问题。而不是这个

mysqldump -u root --password= gestiondestock > path

试试这个,

mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
