这里所说的不是驱动对象,而是这个内核模块在内核内存空间中的地址。这是一个常用的技巧:在驱动对象中DriverStart域和DriverSize域分别记载着这个驱动对象所代表的内核模块在内核空间中的开始地址和大小。

1>避免创建不必要的对象
2>如果方法用不到成员变量,可以把方法声明为static,性能会提高15%到20%
3>避免使用getters/setters存取Field,可以把Field声明为public,直接访问
4>static的变量如果不需要修改,应使用static final 修饰符定义为常量
5>使用增强for循环语法——for(:)
6>私有内布类要访问外部类的Field或方法,可以把外部类的Field或方法声明为包访问权限
7>合理使用浮点数,浮点数比整型慢两倍

这大概是由xml文件中的编码规则决定要这么变换。
在xml文件中有以下几类字符要进行转义替换:

<

<

小于号

&gt;

>

大于号

&amp;

&

&apos;

'

单引号

&quot;

"

双引号

  请求登录人人网比较麻烦,需要记住cookie,尤其是这句代码,
httpContext.setAttribute(ClientContext.COOKIE_STORE,httpClient.getParams().getParameter("CookieStore"));
试了很多遍才找到httpClient.getParams().getParameter("CookieStore"))。

主要代码如下:

package com.koyo.downloadphoto.service.impl;

import java.io.File;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;

         // 输出流,会抛出异常!
         // 所以,使用辅助的工具类来创建一个文件输出流:FileUtils.openOutputStream(new

遇到这种问题,请参照这种写法:
s|Application
