java 备份mysql（可用于windows和linux）独立类

本人菜鸟，代码很烂，各位就将就看吧（独立类，自己使用的时候是为了方便web应用的）

 

/**
* 
* @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 block
e.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) {
