3、配置struts-config.xml文件；建立action、formbean;
改配置可以自動生成，使用eclipse進(jìn)行自動生成，在建立時，如下圖，可直接生成對應(yīng)的action類和formbean類。
?1?<?xml?version="1.0"?encoding="UTF-8"?>
?2?<!DOCTYPE?struts-config?PUBLIC?"-//Apache?Software?Foundation//DTD?Struts?Configuration?1.1//EN"?"http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
?3?
?4?<struts-config>
?5?????<data-sources?/>
?6?????<form-beans>
?7?????????<form-bean?name="LoginForm"?type="com.test.web.form.LoginForm"?/>
?8?
?9?????</form-beans>
10?
11?????<global-exceptions?/>
12?????<global-forwards?/>
13?????<action-mappings>
14?????????<action?attribute="LoginForm"?input="/login.jsp"?name="LoginForm"?path="LoginAction"?scope="request"?type="com.test.web.action.LoginAction" validate="true">
15?????????????<forward?name="faile"?path="faile.jsp"?/>
16?????????????<forward?name="success"?path="success.jsp"?/>
17?????????</action>
18?
19?????</action-mappings>
20?
21?????<message-resources?parameter="ApplicationResources"?/>
22?</struts-config>
對應(yīng)生成的formbean如下代碼所示:
?1?import?javax.servlet.http.HttpServletRequest;
?2?import?org.apache.struts.action.ActionErrors;
?3?import?org.apache.struts.action.ActionForm;
?4?import?org.apache.struts.action.ActionMapping;

FormBean中驗證后的提示需要在ApplicationResources_zh_CN.properties中配置提示錯誤信息.
1?username.null.error=\u5462\u79f0\u4e0d\u80fd\u4e3a\u7a7a
2?password.null.error=\u5bc6\u7801\u4e0d\u80fd\u4e3a\u7a7a
下面我們需要對WEB展現(xiàn)中對Action進(jìn)行配置;我們在這里主要是針對登錄進(jìn)行開發(fā).因此在action中需要完成以下步驟:
1、登錄驗證；驗證用戶名是否存在。驗證該用戶的密碼是否正確。
2、增加cookie
3、提示登錄成功。
在進(jìn)行Action類的編寫過程中，首先我們需要考慮到對數(shù)據(jù)的操作有如下步驟。
1、驗證用戶名是否存在，我們在service層需要提供一個接口:
1?Public?boolean?isExist(String?user);
來判斷用戶名是否存在，同時要考慮該用戶名對應(yīng)的密碼是否正確，需要提供接口:
1?Public?UserBasicInfo?findByUser(String?user);
通過用戶名來查找相關(guān)數(shù)據(jù)。
在Action中，我們同時要判斷根據(jù)用戶查找的用戶密碼是否正確。如果正確，增加cookie。并返回正常登錄頁面。如果用戶不存在、該用戶輸入的密碼與數(shù)據(jù)庫中的密碼不相符合。則在配置文件ApplicationResources_zh_CN.properties中，進(jìn)行設(shè)置提示報錯內(nèi)容。并在頁面中顯示。
具體Action代碼如下:
?
??1?public?ActionForward?execute(
??2?????????ActionMapping?mapping,
??3?????????ActionForm?form,
??4?????????HttpServletRequest?request,
??5?????????HttpServletResponse?response)?{
??6?????????ActionMessages?errors?=?new?ActionMessages();

首先謝謝各位的關(guān)注,因最近項目比較緊張,一直沒有更新該文章，有點對不住了。
下面我將service層的實現(xiàn)與Dao層的實現(xiàn)與配置寫上。各位自己參考吧。
service接口實現(xiàn)
1?public?boolean?isExists(String?userEmail)?{
2?
3?????????if?(userBasicInfoDao.findByUserEmail(userEmail).size()?==?0)
4?????????????return?false;
5?????????else
6?????????????return?true;
7?????}
通過service層調(diào)用Dao層接口，進(jìn)行判斷用戶是否存在。
Dao接口實現(xiàn)：
1?public?List?findByUserEmail(String?userEmail)?{
2?
3?????????return?getHibernateTemplate().find(
4?????????????????"from?CoreUserbasicinfo?cc?where?cc.useremail=?",?userEmail);
5?
6?????}
接下來，我們就需要配置spring的配置文件
applicationContext-service.xml
?1?<bean?id="userBasicInfoManager"?parent="txProxyTemplate">
?2?????????<property?name="target">
?3?
?4?????????????<bean
?5?????????????????class="包路徑.service.Impl.UserBasicInfoMgrImpl">
?6?????????????????<property?name="userBasicInfoDao">
?7?????????????????????<ref?bean="UserBasicInfoDao"?/>
?8?????????????????</property>
?9?????????????????<property?name="mailsender">
10?????????????<ref?bean="mailSender"?/>
11?????????</property>
12?????????<property?name="message">
13?????????????<ref?bean="mailMessage"?/>
14?????????</property>
15?????????????</bean>
16?????????</property>
17?????</bean>
