一个放一个拿，operationBox()锁住stack的操作，forsleep方法是进行休眠的，模拟一块一慢，如果需要无序时间，自己写随机函数进行线程休眠。
每次请求参数或者sql作为缓存key,如果key存在从缓存取,否则走数据库,结果缓存.缓存框架选择因业务而异
java代码 30分 呵呵
这种的建议用htmlcleaner的类包解析
直接就是java对象
public class URLReader {
public String readResponseFromURL(String url) throws MalformedURLException, IOException {
// open reader for URL
InputStreamReader in = new InputStreamReader(new URL(url).openStream());
// read contents into string buffer
StringBuilder input = new StringBuilder();
int ch;
while ((ch = in.read()) != -1) {
input.append((char) ch);
}
return input.toString();
}
}
调用
URLReader reader = new URLReader();
String input = reader.readResponseFromURL(url);
TagNode node = htmlCleaner.clean(input);
这里node就是html的节点了
所有的都可以从里面取得
