S2SH項目結(jié)合Flex實現(xiàn)登錄

1、下午五點，終于搞定，高興今天是冬至節(jié)，剛?cè)プ隽艘患媸虑?，自娛了一把，我們公司在一座五星寫字樓里面，裝修豪華，廁所的地板是橡膠瓷磚的那種，每次小便器前總有一塊瓷磚上面布滿了“地圖”，打掃衛(wèi)生的人寫了一張紙貼在墻上“大家注意，往前一步，文明一大片”，我剛剛偷偷的換了一張紙，上書“尿不進(jìn)去，說明你短”，哈哈開始寫這個文檔，我是實習(xí)生，很菜，很多東西不會，這個東西我配置了一天，剛配好，記錄下來。首先聲明，我這個事針對J2EE程序員的，不是針對Flex的，我的初衷就是在J2EE里加入Flex支持。有人說用flex沒必要用Struts，但是，我說用上最好，因為你不是每個頁面都用flex處理，很多很復(fù)雜

2、的流程flex投入巨大，所以還是普通jsp搞定最好。所以加上一層action不會影響太多性能的。嘿嘿。這個文檔是建立在你已經(jīng)學(xué)習(xí)了三大框架的而且已經(jīng)會三大框架的整合開發(fā)的基礎(chǔ)上的。要對整個流程熟悉，才能自己完成這個項目。其中有什么問題大家可以加我qq:402026752來討論。也可以給我發(fā)郵件索要工程源文件。在此提醒大家一點，flex加入后的S2SH項目不能直接導(dǎo)入，不然會有很多問題，主要是tomcat的webapps下沒有相關(guān)的配置文件，所以還是按照這個文檔一步一步來吧。Flex4的插件安裝方法網(wǎng)上有很多的，必須MyEclipse7.5以上，但是9.0的不要嘗試了。我已經(jīng)試過了，失敗了。我的

3、配置如下： MyEclipse8.5； Flex4插件版； Tomcat 6.0.26； BlazeDS 4.0；1, newàweb project,命名為flextest，這個我想不用截圖吧2 加入S2SH三大框架的jar包，也可以使用MyEclipse導(dǎo)入，配置各個配置文件。這個就是三大框架集成過程，不想多啰嗦。完成后的架構(gòu)圖先上一張：這是我完全做完后的效果圖這個項目雖然很小很簡單，但是我采用的是jspàactionàserviceàdaoà數(shù)據(jù)庫的標(biāo)準(zhǔn)工程做法。其中src中的hibernateutil包可以不要，這個是動力節(jié)點老師王勇寫

4、的工具包，主要就是導(dǎo)出Model到數(shù)據(jù)庫中，整個例子很簡單。我將代碼全部貼出來。到這一步你的工程里還沒有flex任何東西，但是我的截圖里有，這個你不用急往下看，你的SSH項目能運行起來才是關(guān)鍵。User.java:package com.xaut.bean;public class User private Integer id;private String username;private String password;public Integer getId() return id;public void setId(Integer id) this.id = id;public Str
