【正文】 (3)系主任管理 系主任由 此批量 錄入學(xué)生以及教師信息并負(fù)責(zé)進(jìn)行對教師所出的題目進(jìn)行審核，只有 審核通過的題目 學(xué)生才可以進(jìn)行選題，同時系主任還擁有對教師 和 學(xué)生帳號進(jìn)行凍結(jié)的權(quán)限。 2 各系主任登陸系統(tǒng)后可以對自身的信息進(jìn)行維護(hù)，以及為本系的教師和學(xué)生創(chuàng)建系 統(tǒng)用戶，各系只能查看本系的相關(guān)信息。 2系統(tǒng)用戶登陸 a).正確的選擇用戶 類型、輸入用戶名和密碼 就 可以進(jìn)入系統(tǒng)用戶管理信息界面。 1注冊會話信息 HttpSession currentSession = (false)。//保存用戶姓名 (userCode,userCode)。 (session_id,sessionId)。 同時將信息增加到用戶會話信息表 bsm_session_info 中 系統(tǒng)用戶管理 a).系統(tǒng)用戶信息管理 （如圖 5） 只有系統(tǒng)管理員和系主任具有對用戶信息的操作權(quán)限 ,其他人員沒有操作權(quán)限 ,代碼在 jsp 中實現(xiàn)： if(!((0)||(1))) { throw new DataException(對不起沒有查看權(quán)限！ )。 % } % 圖 5： 系統(tǒng)用戶管理界面 查詢 —— 選擇不同條件進(jìn)行組合查詢，就可以查詢出相關(guān)的用戶信息。實現(xiàn)代碼： 該功能只有系主任才能使用 該功能只會在主任操作時出現(xiàn)，同時只有用戶類型為指導(dǎo)教師時使用 if( ==2) { =inputname=\stu_num\ type=\text\ desType=\NUMBER\ value=\\ maxlength=\2\ isNeed=\1\ des=\指導(dǎo)學(xué)生人數(shù) \ size=\10\人 。 凍結(jié) —— 當(dāng)系統(tǒng)用戶的帳號到期，管理員和系主任就要對用戶信息凍結(jié)。 如圖 7： 圖 7：導(dǎo)入用戶信息界面 歷屆信息查看 歷屆信息查看功能是對歷年作過的畢業(yè)設(shè)計做的統(tǒng)計進(jìn)行備份記載，它是為了方便教師和學(xué)生查詢以做出題和選題參考，還為系主任對題目的審核提供參考。 審批 —— 老師根據(jù)對學(xué)生選擇的題目進(jìn)行審核決定學(xué)生最后的畢業(yè)論文課題 。錄入的題目必須經(jīng)過系主任的審核后學(xué)生才能進(jìn)行選擇。 ⑵ 增加：可以增加自己的論文題目，但必須是在自己所選的題目未被老師審核的情況下。 可以 增加自己的論文題目 當(dāng)用戶進(jìn)行完他的系統(tǒng)操作后他就要通過 點擊“退出系統(tǒng)” 退出系統(tǒng)當(dāng) 他將退出系統(tǒng) 后系統(tǒng)將自動 注銷 session。 (jdbc:microsoft:.dbport+。 (1)。 ()。 } String num = (String)(clsName)。 } catch (Exception ex) { ()。 //Multipart 對象 ,郵件內(nèi)容 ,標(biāo)題 ,附件等內(nèi)容均添加到其中后，再生成 MimeMessage 對象 (mp)。 (DEBUG)。 (mimeMsg,())。 6 技術(shù)難點分析 本系統(tǒng)采用 MVC 的架構(gòu)，它可以解決完全由 JSP 或完全由 servlet 實現(xiàn)的應(yīng)用程序中的固有的問題。在這個應(yīng)用程序中，當(dāng)需要和數(shù)據(jù)源進(jìn)行交互的時候則使用這個接口，并且編寫一個單獨的類來實現(xiàn)這個接口在邏輯上對應(yīng)這個特定的數(shù)據(jù)存儲。要保持良好的動態(tài)性就要求與數(shù)據(jù)庫有良好的連接。 參考文獻(xiàn) [1] 耿詳義 .JSP實用教程 [M].北京： 清華大學(xué)出版社， 2020。 [4] 盧銀鵑 .JSP網(wǎng)絡(luò)開發(fā)技術(shù) [M].北京： 人民郵電出版社， 2020。 [8] 周良中 .

We will finish the bowl, the gypsy said. There is over half a skin. We packed it in on one of the horses. That was the last raid of Pablo, Anselmo said. Since then he has done nothing. How many are you? Robert Jordan asked. We are seven and there are two women. Two? Yes. The _mujer_ of Pablo. And she? In the cave. The girl can cook a little. I said she cooks well to please her. But mostly she helps the _mujer_ of Pablo. And how is she, the _mujer_ of Pablo? Something barbarous, the gypsy grinned. Something very barbarous. If you think Pablo is ugly you should see his woman. But brave. A hundred times bra ver than Pablo. But something barbarous. Pablo was brave in the beginning, Anselmo said. Pablo was something serious in the beginning. He killed more people than the cholera, the gypsy said. At the start of the movement, Pablo killed more people than the ty phoid fever. But since a long time he is _muy flojo_, Anselmo said. He is very flaccid. He is very much afraid to die. It is possible that it is because he has killed so many at the beginning, the gypsy said philosophically. Pablo killed mor e than the bubonic plague. That and the riches, Anselmo said. Also he drinks very much. Now he would like to retire like a _matador de toros_. Like a bullfighter. But he cannot retire. If he crosses to the other side of the lines they will take his horses and make him go in the army, the gypsy said. In me there is no love for being in the army either. Nor is there in any other gypsy, Anselmo said. Why should there be? the gypsy asked. Who wants to be in an army? Do we make the revolution to be in an army? I am willing to fight but not to be in an army. Where are the others? asked Robert Jordan. He felt fortable and sleepy now from the wine and lying bac k on the floor of the forest he saw through the tree tops the small afternoon clouds of the mountains moving slowly in the high Spanish sky. There are two asleep in the cave, the gypsy said. Two are on guard above where we have the gun. One is on guard below. They are probably all asleep. Robert Jordan rolled over on his side. What kind of a gun is it? A very rare name, the gypsy said. It has gone away from me for the moment. It is a machine gun. It must be an automatic rifle, Robert Jordan thought. How much does it weigh? he asked. One man can carry it but it is heavy. It has three legs that fold. We got it in the last serious raid. The one before the wine. How many rounds have you for it? An infinity, the gypsy said. One whole case of an unbelievable heaviness. Sounds like about five hundred rounds, Robert Jordan thought. Does it feed from a pan or a belt? From round iron cans on the top of the gun. Hell, it39。re bigger than you look, and ran her hand over his shoulder, feeling the muscle under the flannel shirt. Good. I am very content that you have e. And I equally. We will understand each other, she said. Have a cup of wine. We have already had some, Robert Jordan said. But, will you? Not until dinner, she said. It gives me heartburn. Then she sighted Pablo again. _Borracho!_ she shouted. Drunkard! She turned to Robert Jordan and shook her head. He was a very good man, she told him. But now he is terminated. And listen to me about another thing. Be very good and careful about the girl. The Maria. She has had a bad time. Understandest thou? Yes. Why do you say this? I saw how she was from seeing thee when she came into the cave. I saw her watching thee before she came out. I joked with her a little. She was in a very bad state, the woman of Pablo said. Now she is better, she ought to get out of here. Clearly, she can be sent through the lines with Anselmo. You and t
