Eclipse搭建SSH（Struts2+Spring3+Hibernate3）框架项目教程
前言
确实好久没有写过了，一直以来把写博文当作自己学习的总结，当作做过的笔记，随时都可以拿出来看看。不过最近习惯了用OneNote和印象笔记，所以就很少在论坛写博文。但是偶尔看到几篇被转载了，也小小的虚荣了下。这种虚荣大神们已经习以为常，他们是不能理解的。
好吧，转入正题。
参加工作从事JavaWeb开发将近两年，也没有完整的搭建出一个SSH框架的项目，说出来确实有点不好意思，并且前一段一个朋友问我搭建过SSH框架没，我都没有好意思说没有。所以才有了搭建一个SSH框架项目的想法，因此有了今天的这篇博文。
这篇博文的目的
尝试搭建一个完整的SSH框架项目。给以后的自己，也给别人一个参考。
读博文前应该注意：
本文提纲：本文通过一个用户注册的实例讲解SSH的整合。创建Struts项目，整合Hibernate，整合Spring。最后总结如何熟练创建SSH项目。仅是创建SSH项目，对于其他的扩展例如Struts的国际化，Hibernate的缓存优化，Spring的AOP等，本博文涉及不到。想学习更多的东西请搜索其他博文。本项目的环境：Windows 8-64位，Eclipse Indigo Service Release 2，Tomcat 7.0，Struts-2.2.3.1，spring-framework-3.2.3.RELEASE(本来使用Spring3.1，但是整合Spring的时候启动服务器报错。错误信息竟然是Spring框架中的方法参数空指针。。。对比Spring3.2版本后，发现在3.2种增加了判断此参数是否为空，所以最终改为用Spring3.2.3的版本。详细错误信息见本目录下5)，hibernate-release-4.0.0.CR6(整合Spring3时，可以启动服务器，但是点击注册后调用UserDao类的getHibernateTemplate().save(Obj)时浏览器页面报错，但是服务器没有反应。提示org.hibernate.SessionFactory中有没有openSession(Interceptor interceptor)
方法，但是Spring框架中的代码Session session = (entityInterceptor != null ? sessionFactory.openSession(entityInterceptor) : sessionFactory.openSession())显示用到该方法，虽然调用这段代码的方法传进来的entityInterceptor就为null。。。网上搜索无果，所以最终在整合Spring的时候使用Hibernate-3.6.10.Final。详细错误信息见本目录下6)，MySQL 5.5.28下的project数据库。user表的创建脚本。[sql] view plain copy
print?
createtableuser(
userIdintauto_increment,
userNamevarchar(16)notnull,
passwordvarchar(16)notnull,
genderintnotnull,
primarykey(userId)
);
create table user(
userId int auto_increment,
userName varchar(16) not null,
password varchar(16) not null,
gender int not null,
primary key(userId)
);
使用Spring3.1时出现错误的详细信息。[plain] view plain copy
print?

创建Struts项目
创建工程
在Eclipse中创建一个DynamicWeb Project，本文项目名称为SSHProject。把Struts内apps文件夹下的struts2-blankwar包用压缩工具解压，然后把WEB-INF/lib内的jar包和WEB-INF下的web.xml文件分别复制到SSHProject项目下的WEB-INF/lib内和WEB-INF下。在src目录下创建相应package。在WebContent下创建Register.jsp文件，并分别创建注册成功和注册失败的Success.jsp和Fail.jsp。

在Struts基础上整合Hibernate
整合Hibernate
将Hibernate内的lib/required下的jar包和lib/jpa下的jar包复制到SSHProject项目的lib目录下。在上面Struts项目的基础上添加com.ynwi.ssh.dao和com.ynwi.ssh.daoImpl包。分别创建BaseDao接口和UserDao类。
在数据库中创建对应的表user来写入要注册的用户。创建表的脚本见前言说明部分。创建user表的Hibernate映射文件。因为这里要创建user表对应的POJO类，所以我这里把之前com.ynwi.ssh.beans包改成com.ynwi.ssh.forms包，用来存放页面传过来的表单数据，新创建com.ynwi.ssh.beans包，用来创建POJO对象来对应数据库中的表。路径：POJO类同目录。
建立Hibernate配置文件。路径：src目录下。
编写Session工厂类。整合Spring后，数据源的创建和SessionFactory的创建都交给Spring去管理，就无需这个工厂类了，所以这里我临时创建在daoImpl包里面。
修改业务逻辑实现类。
操作完成后的结构如图所示：
编写代码

}
@Override
public void setSession(Session session) {
this.session = session;
}
@Override
public void saveObject(Object obj) throws HibernateException {
session.save(obj);
}
}
表user的POJO类User.java的内容，因为跟UserForm.java内容差不多，所以不再列出。这个比UserForm.java多一个userId属性，因为在表user里面有userId的column。在POJO类里需要跟这个column有映射。POJO类User.java的Hibernate映射文件User.hbm.xml的内容。代码说明将根据本地数据库的设置来创建userId，如MySQL中将表user的userId设置为自动增长，则在保存记录是，userId将自动增长。对于需要在程序中指定主键的值，则将generator的class属性设置为assigned。

在Struts +Hibernate项目中整合Spring
整合Spring
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。
操作完成后的结构如图所示：
编写代码
Spring的配置文件applicationContext.xml的内容。

总结
唠叨
本来想创建Struts2 + Spring3 +Hibernate4的项目，结果行动之后才发现版本之间不兼容的现象挺严重(我自己是这么认为的，如果有大神看出来是我开发中出的问题导致麻烦告知下)，不得不把Hibernate4换成Hibernate3。因为中间换框架，所以导致此博文中整合hibernate部分是否会报错，不过最终的项目是可以执行的。我会把项目打包上传到csdn资源上。可以下载。
如何快速开发SSH框架项目
创建DynamicWebProject并且导入jar包。
我习惯上把classes文件夹由build文件夹内转移到WEB-INF下。在项目上右键Build Path——〉ConfigureBuild Path。设置Default output folder。在WEB_INF下面创建web.xml并配置Struts的Filter和Spring的Listener。在WEB-INF下面创建applicationContext.xml并配置数据源，sessionFactory，Transaction以及各Beans信息。在src目录下创建struts.xml用来配置action信息，模板可以从Struts空项目里面拿。这里的action对应的class应该为applicationContext.xml内对应的class的bean的id。
