我正在尝试备份我的数据库,这是我编写的代码,但由于某种原因它没有备份?我正在使用local host (MAMP)
,我正在使用的操作系统是MAC OSX
.
public boolean databaseBackup(String dbName, String dbUserName, String dbPassword, String path) {
String qu = "/Applications/MAMP/Library/bin/mysqldump -u" + dbUserName + " -p" + dbPassword + " --database" + dbName + " -r " + path;
System.out.println(qu);
Process runtimeProcess;
Properties pr = new Properties();
pr.setProperty("user", "username");
pr.setProperty("password", "password");
Connection con = null;
PreparedStatement stmt = null;
try {
con = DriverManager.getConnection("jdbc:mysql://localhost:8889/Database", pr);
runtimeProcess = Runtime.getRuntime().exec(qu);
int processComplete = runtimeProcess.waitFor();
if (processComplete == 0) {
System.out.println("5");
System.out.println("Backed up");
return true;
} else {
System.out.println("Not Backed up");
}
} catch (Exception ex) {
ex.printStackTrace();
}
return false;
}
}
在我的 jframe 表单中,我写了这个:
code.databaseBackup("Database","root", "root", "/Users/dipeshramesh/Dropbox/TeamProject/TeamProject2.sql");
因此,当一个人按下备份按钮时,它会调用code.databaseBackup
方法并执行其工作。
如果我运行它,它会显示一条消息“未备份”,知道吗?
