已过tiktok校招客户端，面经分享面试的话, 一天面完3面, 效率很高, 三天之后就发了offer 字节邮件里面也说了不能泄露面试题, 那我就把我秋招参与美团,字节,腾讯,阿里面试被问到的全部问题总结着写出来了, 这其实是我每一轮面试完之后我都会总结哪里答对了, 哪里没有答对, 总结了一大堆问题出来. 答案未必正确, 我只是给自己写了个简单的一句话概括, 可能不够完善, 建议看官自行回答一下这些问题二本非科班, 暑假在字节实习过, 不过不是tiktok部门, 因此秋招就没啥时间准备面试了, 只投了几个大厂, 顺便也在字节跨部门转正, 阅读详情

现在程序能进入运行界面，当相应的用户进入各用户功能界面后，进行下一步的功能操作时出错下面的错误：
type Exception report

以下是有关用户权限的认证方法，
public class HxexRequestProcessor extends RequestProcessor
{
protected final Log log = LogFactory.getLog(HxexRequestProcessor.class);

/**
* 用户认证方法
*/
@Override
protected boolean processRoles(HttpServletRequest request,
HttpServletResponse response, ActionMapping mapping)
throws IOException, ServletException
{
// 得到映射的路径
String path = mapping.getPath();
// 得到用户所要调用的Action方法的名字
String method = request.getParameter(mapping.getParameter());
if (HxexStringUtils.isEmpty(method))
{
method = StrutsConstants.DEFAULT_METHOD;
}

// 取得不需要校验权限的Action方法
String[] roles = mapping.getRoleNames();
if (roles != null && roles.length > 0)
{
// 进行方法的判断
for (String role : roles)
{
if (method.equals(role))
{
request.setAttribute(StrutsConstants.REQUEST_CHECK_FLAG,
true);
return true;
}
}
}

// 得到Session对象和用户对象
HttpSession session = request.getSession();
User u = (User) session.getAttribute(StrutsConstants.SESSION_USER);

// 如果用于对象不存在，那么说明用户没有登录
if (u == null)
{
// 用户没有执行的权限，跳转到错误页面
processLocale( request, response );
RequestDispatcher rd =
request.getRequestDispatcher( "/errors/noauthority.jsp" );
rd.forward( request, response );
return false;
}

// 判断用户是否为超级用户
String superusers = ExamConfigUtil
.getSysConfigValue(ConfigConstants.SUPER_USER);
String[] users = HxexStringUtils.splitString(superusers,
ConfigConstants.USER_DELIM);
if (HxexStringUtils.contains(users, u.getName()))
{
request.setAttribute(StrutsConstants.REQUEST_CHECK_FLAG, true);
return true;
}

// 得到用户的角色信息
Cache cache = CacheFactory.getCache();
Role role = (Role) cache.get(u.getUserType());
if (role == null)
{
throw new ExamSystemException("Couldn't find the role!");
}

// 进行用户执行功能的判断
Set<Function> functions = role.getFunctions();
for (Function function : functions)
{
Set<Action> actions = function.getActions();
for (Action action : actions)
{
if (path.equals(action.getPath())
&& method.equals(action.getParameter()))
{
request.setAttribute(StrutsConstants.REQUEST_CHECK_FLAG,
true);
return true;
}
}
}

// 用户没有执行的权限，跳转到错误页面
processLocale( request, response );
RequestDispatcher rd =
request.getRequestDispatcher( "/errors/noauthority.jsp" );
rd.forward( request, response );
return false;
}

同时在相应的映射文件中也有相应关的ACTION定义，但是在运行时却出错上面的所说的报错信息，不知道是那里的原因！请各位高手帮忙！

以下是HibernateFilte.java中的doFilter 的方法，用于实现Hibernate事务的开始和提交
public void doFilter(ServletRequest request,
ServletResponse response,
FilterChain chain)
throws IOException, ServletException
{
// 得到SessionFactory对象的实例
SessionFactory sf = HibernateUtil.getSessionFactory();

try
{
// 开始一个新的事务
log.debug("Starting a database transaction");
sf.getCurrentSession().beginTransaction();

log.debug( "Request Path:\t" + ((HttpServletRequest)request).getServletPath() );
// Call the next filter (continue request processing)
chain.doFilter(request, response);

// 提交事务
log.debug("Committing the database transaction");
sf.getCurrentSession().getTransaction().commit();

}
catch (Throwable ex)
{
ex.printStackTrace();
try
{
// 会滚事务
log.debug("Trying to rollback database transaction after exception");
sf.getCurrentSession().getTransaction().rollback();
}
catch (Throwable rbEx)
{
log.error("Could not rollback transaction after exception!", rbEx);
}

// 抛出异常
throw new ServletException(ex);
}
}
难道这个方法在定义上有什么不对的地方吗？请各位高手给出指点！谢谢了～！

cn.hxex.exam.filter.HibernateFilter.doFilter(HibernateFilter.java:71)
方法中没有相应的权限进入
你的struts中没有权限的配置啊

是因为你没有在配置文件中给这个角色赋权限．
在你的．ＸＭＬ配置文件中，有一个ＡＣＴＩＯＮ方法没有注册这个方法权限吧
cn.hxex.exam.filter.HibernateFilter.doFilter(HibernateFilter.java:71)
　在这个方法里，是你们自己封装了．没有给这些用户权限．所以都进不去
