SSH+oracle开发环境搭建。MyEclipse 10+Struts2+Hibernate3.3+Spring3.2.3+tomcat-6.0.35

我的工程导出来的jar包的下载地址为：点击打开链接
一，开发环境准备工作。
0，oracle数据库的表名和表结构如图：
1，我这里用的各个软件版本如下：MyEclipse 10，tomcat-6.0.35 ，struts-2.2.1.1，spring-framework-3.2.3.RELEASE-dist，这里struts-2.2.1.1因为超过60M，传不了CSDN，所以大家自己去下载一下，spring-framework-3.2.3.RELEASE-dist下载地址：http://download.csdn.net/detail/liujianian/8612689，Hibernate3.3我是直接在MyEclipse中加载的，操作步骤如下：
①：建立一个新的web project工程，选择Java EE6.0，点击完成。
②：这里我们需要引入外部的驱动jar包（ojdbc14.jar），下载地址：http://download.csdn.net/detail/liujianian/8612779。将ojdbc14.jar包拷入“test”工程中WebRoot/WEB-INF/lib下
③：选择“test”工程，右击选择“myEclipse”-->"Add Hibernate Capabilities",选择Hibernate3.3，
④：选择“next”
⑤：选择“next”，填写数据库连接的相关信息，这个以后在hibernate.cfg.xml中还可以修改的。
⑥：选择“next”，，我们不创建Session Factory类（将上面的勾去掉），等后面工程里面我自己新建，点击“finish”完成hibernate包的加载。完成后如图会出现以下jar包：参照后面的目录截图
2，外部引入我们下载的Struts包。
①：选择工程右击“Build Path”-->"Add Libraries",，选择“User Library”-->"next"，选择“UserLibraries"，命名为Struts2，选择struts下lib下面的这些包，点击OK这样struts包就加载好了。如图：参照后面的目录截图
3，准备工作做好了，下面我们来进行Struts和hibernate的整合开发，spring最后再整合。
文件目录如下：
①：LoginAction.java(action类)

登陆到数据库的数据：
4，下面我们再来外部加载spring报，参照struts包外部引入，这里就不再重复了。引入的包是spring\libs下面除了javadoc和sources的所有包
引入完了。
整个工程的目录如下图：
- 将Spring内libs目录下包含所有的jar包（不需要复制结尾为sources和javadoc的jar包）到SSHProject项目的lib目录下。
- 编写Spring的配置文件applicationContext.xml。路径：src目录下，需要在web.xml配置context-param指定路径，或者把该文件放在WEB-INF下，跟web.xml同目录。这里由于Spring配置数据源的需要，需要把Hibernate内lib/optional/c3p0下的c3p0-0.9.1.jar复制到lib不目下。
- 修改BaseDao和UserDao。在引入Spring后，需要用Spring进行统一的事务管理，数据源和sessionFactory都交给Spring去生成，因此接口类和实现类BaseDao和UserDao都需要做相应的修改。Spring提供了HibernateDaoSupport类来完成对数据的操作，因此UserDao在实现BaseDao的同时还需要继承HibernateDaoSupport类。并将先前session的操作修改成HibernateTemplate（可通过getHibernateTemplate（）方法来获得）的操作。
- 修改业务逻辑实现类。在没有加入Spring之前，业务逻辑实现类的Session的获得，dao的实例化，以及事务的管理都是该类执行管理的。加入Spring后，这些都交给Spring去管理。该类的dao的实例化由Spring注入。
- 修改用户注册的RegisterAction类。同样，RegisterAction类中的userManager的实例化也由Spring注入。
- 删除Hibernate的配置文件Hibernate.cfg.xml和工厂类HibernateSesseionFactory类。他们的工作已经交给Spring去做，已经不再有用。
- 修改web.xml，加载Spring。要想启动时加载Spring的配置文件，需要在web.xml中配置对应的监听器（listenser），并制定Spring的配置文件。
- 修改Struts的配置文件struts.xml。把原来指定的名为register的action的class由原来的路径变为applicationContext.xml文件中该Action的id。
- LoginAction.java如下，LoginAction-validation.xml没有变化。
package com.ssh.action;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.Preparable;import com.ssh.forms.UserForm;import com.ssh.service.UserManager;public class LoginAction extends ActionSupport implements Preparable{//该类继承了ActionSupport类。这样就可以直接使用SUCCESS, LOGIN等变量和重写execute等方法/** * */private static final long serialVersionUID = 724458459147961157L;private UserForm user; private UserManager userManager; public UserForm getUser() { return user; } public void setUser(UserForm user) { this.user = user; } public UserManager getUserManager() { return userManager; } public void setUserManager(UserManager userManager) { this.userManager = userManager; } @Override public String execute() { try{ user.setUserId("2"); userManager.regUser(user); return SUCCESS; }catch(Exception e){ e.printStackTrace(); return ERROR; }}//清除LoginAction-validation.xml爆出的错误信息public void prepare(){clearErrorsAndMessages();};} - User.java如下：User.hbm.xml没有变化
package com.ssh.beans;public class User {private String userId;private String username; private String password; public String getUserId() {return userId;}public void setUserId(String userId) {this.userId = userId;}public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } } - BaseDao.java
