java實現mysql的匯入和匯出

public class sqlbackup 

public static void backup() 
outstr = sb.tostring();
// 要用來做匯入用的sql目標檔案：
fileoutputstream fout = new fileoutputstream(
"e:/test.sql");
outputstreamwriter writer = new outputstreamwriter(fout, "utf8");
writer.write(outstr);
// 注：這裡如果用緩衝方式寫入檔案的話，會導致中文亂碼，用flush()方法則可以避免
writer.flush();
// 別忘記關閉輸入輸出流
in.close();
xx.close();
br.close();
writer.close();
fout.close();
system.out.println("/* output ok! */");
} catch (exception e) 
} public static void load() 
outstr = sb.tostring();
outputstreamwriter writer = new outputstreamwriter(out, "utf8");
writer.write(outstr);
// 注：這裡如果用緩衝方式寫入檔案的話，會導致中文亂碼，用flush()方法則可以避免
writer.flush();
// 別忘記關閉輸入輸出流
out.close();
br.close();
writer.close();
system.out.println("/* load ok! */");
} catch (exception e) 
} }
