	public Object convertValue(Map context, Object value, Class toType) {
		
		if (User.class==toType)//从页面向后台转换
		{
			String[] str=(String[])value;
			String firstValue=str[0];
			StringTokenizer st=new StringTokenizer(firstValue,":");
			String username=st.nextToken();
			String password=st.nextToken();
			User user=new User();
			user.setUsername(username);
			user.setPassword(password);
			return user;
			
		}
		else if (String.class==toType)//从后台对象向前台转换
		{
			User user=(User)value;
			String username=user.getUsername();
			String password=user.getPassword();
