SSH+oracle開發環境搭建。MyEclipse 10+Struts2+Hibernate3.3+Spring3.2.3+tomcat-6.0.35

我的工程匯出來的jar包的下載地址為：點選開啟連結
一，開發環境準備工作。
0，oracle資料庫的表名和表結構如圖：
1，我這裡用的各個軟體版本如下：MyEclipse 10，tomcat-6.0.35 ，struts-2.2.1.1，spring-framework-3.2.3.RELEASE-dist，這裡struts-2.2.1.1因為超過60M，傳不了CSDN，所以大家自己去下載一下，spring-framework-3.2.3.RELEASE-dist下載地址：http://download.csdn.net/detail/liujianian/8612689，Hibernate3.3我是直接在MyEclipse中載入的，操作步驟如下：
①：建立一個新的web project工程，選擇Java EE6.0，點選完成。
②：這裡我們需要引入外部的驅動jar包（ojdbc14.jar），下載地址：http://download.csdn.net/detail/liujianian/8612779。將ojdbc14.jar包拷入“test”工程中WebRoot/WEB-INF/lib下
③：選擇“test”工程，右擊選擇“myEclipse”-->"Add Hibernate Capabilities",選擇Hibernate3.3，
④：選擇“next”
⑤：選擇“next”，填寫資料庫連線的相關資訊，這個以後在hibernate.cfg.xml中還可以修改的。
⑥：選擇“next”，，我們不建立Session Factory類（將上面的勾去掉），等後面工程裡面我自己新建，點選“finish”完成hibernate包的載入。完成後如圖會出現以下jar包：參照後面的目錄截圖
2，外部引入我們下載的Struts包。
①：選擇工程右擊“Build Path”-->"Add Libraries",，選擇“User Library”-->"next"，選擇“UserLibraries"，命名為Struts2，選擇struts下lib下面的這些包，點選OK這樣struts包就載入好了。如圖：參照後面的目錄截圖
3，準備工作做好了，下面我們來進行Struts和hibernate的整合開發，spring最後再整合。
檔案目錄如下：
①：LoginAction.java(action類)

public class LoginAction extends ActionSupport implements Preparable{
//該類繼承了ActionSupport類。這樣就可以直接使用SUCCESS, LOGIN等變數和重寫execute等方法

@Override

try{
this.setUserManager(new UserManagerImpl());
user.setUserId("1");
userManager.regUser(user);
return SUCCESS;
}catch(Exception e){
e.printStackTrace();
return ERROR;

}

這樣我們的struts+hibernate的實驗工程就OK了，下面我們執行一下如圖：
登陸到資料庫的資料：
4，下面我們再來外部載入spring報，參照struts包外部引入，這裡就不再重複了。引入的包是spring\libs下面除了javadoc和sources的所有包
引入完了。
整個工程的目錄如下圖：
- 將Spring內libs目錄下包含所有的jar包（不需要複製結尾為sources和javadoc的jar包）到SSHProject專案的lib目錄下。
- 編寫Spring的配置檔案applicationContext.xml。路徑：src目錄下，需要在web.xml配置context-param指定路徑，或者把該檔案放在WEB-INF下，跟web.xml同目錄。這裡由於Spring配置資料來源的需要，需要把Hibernate內lib/optional/c3p0下的c3p0-0.9.1.jar複製到lib不目下。
- 修改BaseDao和UserDao。在引入Spring後，需要用Spring進行統一的事務管理，資料來源和sessionFactory都交給Spring去生成，因此介面類和實現類BaseDao和UserDao都需要做相應的修改。Spring提供了HibernateDaoSupport類來完成對資料的操作，因此UserDao在實現BaseDao的同時還需要繼承HibernateDaoSupport類。並將先前session的操作修改成HibernateTemplate（可通過getHibernateTemplate（）方法來獲得）的操作。
- 修改業務邏輯實現類。在沒有加入Spring之前，業務邏輯實現類的Session的獲得，dao的例項化，以及事務的管理都是該類執行管理的。加入Spring後，這些都交給Spring去管理。該類的dao的例項化由Spring注入。
- 修改使用者註冊的RegisterAction類。同樣，RegisterAction類中的userManager的例項化也由Spring注入。
- 刪除Hibernate的配置檔案Hibernate.cfg.xml和工廠類HibernateSesseionFactory類。他們的工作已經交給Spring去做，已經不再有用。
- 修改web.xml，載入Spring。要想啟動時載入Spring的配置檔案，需要在web.xml中配置對應的監聽器（listenser），並制定Spring的配置檔案。
- 修改Struts的配置檔案struts.xml。把原來指定的名為register的action的class由原來的路徑變為applicationContext.xml檔案中該Action的id。
- LoginAction.java如下，LoginAction-validation.xml沒有變化。
