/*** * @param file_path 备份路径 * @return*/public boolean backDatabase(String file_path){String path = getClass().getProtectionDomain().getCodeSource().getLocation().getPath();path = path.substring(0, path.indexOf("WEB-INF/classes"));Properties pro=new Properties();try {/*** ProjectContent.jdbc_config_path jdbc配置文件路径*/FileInputStream fi=new FileInputStream(path + "WEB-INF/classes" + ProjectContent.jdbc_config_path);pro.load(fi);} catch (FileNotFoundException e1) {e1.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}String mysql = "mysqldump --user=" + pro.getProperty("jdbc.username") + " --password=" + pro.getProperty("jdbc.password") + " --opt typmdb_1_0> " + file_path;//数据库名字根据实际情况修改或者也用配置文件System.out.println("dsbakuName============================>"+mysql);System.out.println("dsbakupPath============================>"+file_path);try {Runtime rt = Runtime.getRuntime();String os=System.getProperty("os.name");Process child = null;if(os.toLowerCase().startsWith("win")){child = rt.exec("cmd /c " + mysql);}else if(os.toLowerCase().startsWith("lin")){child = rt.exec(new String[] { "sh", "-c", mysql });}else{System.out.println("other");}try {child.waitFor();} catch(InterruptedException e) {e.printStackTrace();}System.out.println("/* Output OK! */");return true;} catch (IOException e) {e.printStackTrace();return false;}}
