1、tail -f 动态刷新日志信息；
2、tail -f >1234.log，警告：无限制输入跟随标准是无用的，会把1234.log内容清空；

他第二条是在GG之后查看里面的内容，发现没内容了求大神~~解救 进程管理rn1．目的和要求rn加强对进程概念和进程状态转换的理解。rn2．实验内容rn包括：编写程序模拟进程的创建、运行、阻塞、唤醒、终止等过程。rn3．实验环境rn不限。Java、VC++、VB均可。rn4．实验提示rn1）假设内存最多可调入5个进程，即就绪队列中的进程数最多有5个。分别编写进程的创建、运行、阻塞、唤醒、终止等函数，在main函数中通过命令调用各函数，实现进程状态的转换。rn2）至少应包含3个队列，就绪队列、阻塞队列和完成队列，并且各队列随着进程的状态转换而呈动态变化，应能在屏幕上显示出队列的变换情况。此三个队列可用数据结构中的链表、队列或数组来实现。rn3）实验结果可显示的部分内容如下（仅供参考）。

rm -rf /*求大神解救啊 在struts（例如aAction） 用Myeclipse自动生成的DAO类（bDAO），rn配置和注入没有问题。rn1、但是在aAction中用bDAO类的findByXXX（属性就是数据库中列名）会报错，不过用bDAO里的findAll,save方法不会报错切得到正确的值。rn例如：rnpublic String execute() throws Exception rn // TODO Auto-generated method stubrn rn rn rn String str=this.getBrandL();rn List pList=this.getNotebookDAO().findSerices("ThinkPad");rn HttpServletResponse response = ServletActionContext.getResponse();rn response.setCharacterEncoding("utf-8");rnStringBuffer ddd=new StringBuffer();rn for(Notebook no:pList)rn ddd.append(no.getSeries());rn ddd.append(",");rn rn String arr=ddd.substring(0,ddd.length()-1);rn rn response.getWriter().print(arr);rn return null;rn rnrn2、但是不在struts action类里，而新建一个主类测试（主类配置在spring中了DAO类当然也配置在spring中）不会出错。为了区别为试过两种方法都成功了rn<1>、不在spring中配置主类，用原始的spring调用方法调试例如：rn rn rnApplicationContext ctx=new FileSystemXmlApplicationContext("WebRoot/WEB-INF/applicationContext.xml"); rn OtherTest con=ctx.getBean("otherTest", OtherTest.class);（原始调用）rn接下来调用DAO类里各种方法都成功。rn2、在spring中配置主类和DAO类。例如：rnString str="ThinkPad";rn List pList=this.getNotebookDAO().findByTrademark(str);rn（spring配置和注入了主类和DAO类）rn接下来调用DAO类里各种方法成功。rn3、我尝试在DAO类（自动生成的用HibernateTemplate接口）自己写入HibernateCallBack用来实现各种findByXXX（属性，也就是列名），然后在上面的各种环境下使用均获得成功。rn例如：rnpublic boolean isExist(final String account) //判断用户是否存在rn List list = (List) getHibernateTemplate().execute(new HibernateCallback() rn public Object doInHibernate(Session session) throws HibernateException rn List result = session.createCriteria(Consumer.class).add(Restrictions.eq("account", account)).list();rn return result;rn rn );rn if(list.size()>0) rn return true;rn else rn return false;rn rn （这些系统没有自动生成）rn我现在就是不明白为什么在各种情况下为什么结果不同；既然都是系统自动生成的为什么在struts action下有区别（是我配置有问题还是为什么）。既然系统都生成了DAO类而且在其他类里都可以使用为什么不能在struts2 里也用到findByXXX各种方法（我实在是不想再自己写入其他代码，自动生成的代码应该可以用，只是我还没有实现）。

- 数据结构的一道题求大神解救
- Descriptionrn小明很喜欢玩射击游戏。他刚考完了数据结构期末考试，感觉不错，于是又来到了射击娱乐场放松一下。和上次一样，先从老板那租了一把步枪和装有N发子弹的弹夹。这里，再把规则说一遍。在射击的过程中，小明每次都有两种选择：从弹夹中取出一颗子弹上膛，或者打一发子弹出去。注意：所有的子弹都从枪口上膛。小明感觉这有点像《数据结构》课程中的“栈”的特点。因此在打完了这N发子弹之后，他想验证一下这些子弹打出来的顺序是不是真的满足“栈”的特性。假设N颗子弹的编号为1,2,…,N。子弹从弹夹中取出的顺序也是从1到N，这里N = 10。给定一个子弹被打出的顺序，你可以帮小明验证它满不满足“栈”的打出顺序吗？rnInputrn可能有多个测试输入，第一行给出总共的测试输入的个数。rn每个测试输入只有一行：用空格隔开的十个数，表示子弹打出的编号顺序。rnOutputrn对每个测试输入，输出只有一行：rn“Yes”，如果打出顺序满足“栈”的特点；rn“No”，如果打出顺序不满足“栈”的特点。rnSample Inputrn3rn1 2 3 4 5 6 7 8 9 10rn10 9 8 7 6 5 4 3 2 1rn3 1 2 4 5 6 7 8 9 10rnSample OutputrnYesrnYesrnNornrn这是我的代码，为什么WA啊？求救啊rn[code=c]rn#include rn#include rnusing namespace std;rnrnint main() rn int a[10], n = 0, i = 0, j = 0;rn bool k = true;rn stack s[10];rn cin >> n;rn while (n--) rn for (i = 0; i < 10; i++) rn cin >> a[i];rn rn for (i = 0; i < 10; i++) rn if (i > 0) rn if (a[i] - a[i - 1]) rn j++;rn rn rn s[j].push(a[i]);rn rn j = 0;rn for (i = 0; i < 10; i++) rn if (s[j].empty()) rn j++;rn rn if (i + 1 != s[j].top()) rn k = false;rn rn s[j].pop();rn rn if (k == true) rn cout << "Yes\n";rn else rn cout << "No\n";rn rn j = 0, k = true;rn rn return 0;rn[/code]
