Ssh整合开发介绍和简单的登入案例实现

一 介绍：

Ssh是strtus2-2.3.1.2+ spring-2.5.6+hibernate-3.6.8整合的开发，这是目前我的整合开发的使用技术和版本，使用的数据库为mySql。使用的开发工具是eclipse,eplipse的版本为Indigo Service Release 2

二 搭建环境

1． 首先要先引入struts2和sping和hibernate所需要的包

（1）struts2的包为：

struts-2.3.1.2\lib\ struts2-core-2.3.1.2.jar

struts-2.3.1.2\lib\ognl-3.0.4.jar

struts-2.3.1.2\lib\ xwork-core-2.3.1.2.jar

struts-2.3.1.2\lib\ freemarker-2.3.18.jar

struts-2.3.1.2\lib\commons-fileupload-1.2.2.jar

struts-2.3.1.2\lib\ commons-io-2.0.1.jar

struts-2.3.1.2\lib\commons-lang-2.5.jar

struts-2.3.1.2\lib\commons-logging-1.1.1.jar

struts-2.3.1.2\lib \struts2-json-plugin-2.3.1.2.jar

struts-2.3.1.2\lib \struts2-spring-plugin-2.3.1.2.jar

(2)引入hibernate的包

hibernate-distribution-3.6.8.Final\lib\required\*.jar 所有的jar包

hibernate-distribution-3.6.8.Final\lib\jpa\hibernate-jpa-2.0-api-1.0.1.Final.jar

hibernate-distribution-3.6.8.Final\ hibernate3.jar

(3)spring的包为：

spring-framework-2.5.6\dist\ spring.jar

spring-framework-2.5.6\lib\c3p0\c3p0-0.9.1.2.jar

spring-framework-2.5.6\lib\aspectj\*.jar

spring-framework-2.5.6\lib\j2ee\common-annotations.jar

spring-framework-2.5.6\lib\log4j\log4j-1.2.15.jar

spring-framework-2.5.6\lib\jakarta-commons\ commons-logging.jar

spring-framework-2.5.6\lib\cglib\cglib-nodep-2.1_3.jar

spring-framework-2.5.6\lib\dom4j\dom4j-1.6.1.jar

2． 配置spring下所需要的文件

（1）首先配置spring所需要的xml文件

我们在class下，即在src下创建一个applicationContext.xml的xml文件，文件的头文件因为要用到各种标签，所以我们在引入头文件的时候尽量引的比较多点，代码为:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
</beans>

（2）在xml中配置和数据库相关联，并用c3p0来配置数据库连接池

<!-- 数据库的连接池 -->

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"

destroy-method="close">

<property name="driverClass" value="com.mysql.jdbc.Driver"/>

<property name="jdbcUrl"

value="jdbc:mysql://localhost:3306/spring?useUnicode=true&characterEncoding=UTF-8" />

<property name="user" value="root" />

<property name="password" value="1234" />

<!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->

<property name="initialPoolSize" value="1" />

<!--连接池中保留的最小连接数。 -->

<property name="minPoolSize" value="1" />

<!--连接池中保留的最大连接数。Default: 15 -->

<property name="maxPoolSize" value="300" />

<!--最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->

<property name="maxIdleTime" value="60" />

<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->

<property name="acquireIncrement" value="5" />

<!--每60秒检查所有连接池中的空闲连接。Default: 0 -->

<property name="idleConnectionTestPeriod" value="60" />

</bean>

当然，这样所写的可以在一个properties中读取。读取外部文件在xml中的使用为：

<!-- 读取外部的文件 -->

<context:property-placeholder location="jdbc.properties" />

(3)配置sessionFactory工厂，相当于是hibernate.cfg.xml里面的配置

<!-- sessionFactory工厂 -->

<bean id="sessionFactory"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<!-- 注入数据源 -->

<property name="dataSource" ref="dataSource"></property>

<!-- hibernate映射文件的引入 -->

<property name="mappingResources">

<list>

<value>cn/csdn/hr/s2sh/domain/Admin.hbm.xml</value>

</list>

</property>

<!-- 配置hibernate属性的设置 -->

<property name="hibernateProperties">

<props>

<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>

<prop key="hibernate.hbm2ddl.auto">update</prop>

<prop key="hibernate.show_sql">true</prop>

<prop key="hibernate.format_sql">true</prop>

</props>

</property>

</bean>

3．配置struts2.xml中需要的内容

(1)配置基本的struts2.xml

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

<!--使用spring创建管理struts2的action操作 -->

<constant name="struts.objectFactory" value="spring"/>

<include file="struts-admin.xml"></include>

</struts>

注：其中include是引入的文件，一下的语句是非常重要的：

<constant name="struts.objectFactory" value="spring"/>，它是struts2和spring的连接的关键

(2)引入的struts-admin.xml文件，意在检测并作出一个简单的登入的实现

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

<package name="admin" extends="struts-default" namespace="/csdn">

<!-- class的名称 等于spring中action配置文件中的id名称 -->

<action name="loginAdmin" class="adminAction" method="login">

<result name="success">../index.jsp</result>

</action>

</package>

</struts>

4． Hibernate.cfg.xml中的内容可以省略，它已经在spring中的xml中配置了

5．搭建层之间的关系

(1)首先是domain，包为cn.csdn.hr.s2sh.domain,我们以admin为例

属性为id和name和pass

封装的实体类为:

package cn.csdn.hr.s2sh.domain;

import java.io.Serializable;

public class Admin implements Serializable {

private static final long serialVersionUID = 1L;

private Integer id;

private String name;

private String pass;

public Admin() {

super();

// TODO Auto-generated constructor stub

}

public Admin(Integer id, String name, String pass) {

super();

this.id = id;

this.name = name;

this.pass = pass;

}

public Integer getId() {

return id;

}

public void setId(Integer id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getPass() {

return pass;

}

public void setPass(String pass) {

this.pass = pass;

}

@Override

public String toString() {

return "Admin [id=" + id + ", name=" + name + ", pass=" + pass + "]";

}

}

(2)在同一个包下的实体类的映射文件

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="cn.csdn.hr.s2sh.domain">

<class name="Admin" table="admin">

<id name="id" column="id">

<generator class="native"></generator>

</id>

<property name="name" column="name"></property>

<property name="pass" column="pass"></property>

</class>

</hibernate-mapping>

(3)创建dao层，创建的包名为cn.csdn.hr.s2sh.dao，创建的接口名为AdminDao,类名为AdminDaoImpl

下面是创建的接口 AdminDao.java

package cn.csdn.hr.s2sh.dao;

import java.util.List;

import cn.csdn.hr.s2sh.domain.Admin;

public interface AdminDao {

public Admin login(final String name,final String pass);

}

创建的类为AdminDaoImpl.java

package cn.csdn.hr.s2sh.dao;

import java.sql.SQLException;

import java.util.List;

import org.hibernate.HibernateException;

import org.hibernate.Session;

import org.springframework.orm.hibernate3.HibernateCallback;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import cn.csdn.hr.s2sh.domain.Admin;

@SuppressWarnings("unchecked")

public class AdminDaoImpl extends HibernateDaoSupport implements AdminDao {

public Admin login(final String name, final String pass) {

return (Admin) this.getHibernateTemplate().execute(

new HibernateCallback() {

public Object doInHibernate(Session session)

throws HibernateException, SQLException {

// TODO Auto-generated method stub

Object obj = session

.createQuery(

"from Admin where name=:name and pass=:pass")

.setString("name", name)

.setString("pass", pass).uniqueResult();

return obj;

}

});

}

}

(4)创建service层，创建的包名为cn.csdn.hr.s2sh.service

创建的AdminService.java接口

package cn.csdn.hr.s2sh.service;

import cn.csdn.hr.s2sh.dao.AdminDao;

public interface AdminService extends AdminDao{

}

创建的AdminServiceImpl.java

package cn.csdn.hr.s2sh.service;

import java.util.List;

import org.springframework.transaction.TransactionStatus;

import org.springframework.transaction.support.TransactionCallback;

import org.springframework.transaction.support.TransactionTemplate;

import cn.csdn.hr.s2sh.dao.AdminDao;

import cn.csdn.hr.s2sh.domain.Admin;

public class AdminServiceImpl implements AdminService {

private AdminDao adminDao;

public void setAdminDao(AdminDao adminDao) {

this.adminDao = adminDao;

}

public Admin login(String name, String pass) {

// TODO Auto-generated method stub

return adminDao.login(name, pass);

}

}

6.创建访问struts2的时候的action，我们把action放到一个bean-action.xml中

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<!-- 创建struts2中的action -->

<!-- 配置admin的action -->

<bean id="adminAction" class="cn.csdn.hr.s2sh.action.AdminAction"

scope="prototype">

<property name="adminService" ref="adminService"></property>

</bean>

</beans>

而ref的adminServiceImpl是在bean-service.xml中

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<!-- admin的业务操作 -->

<bean id="adminServiceImpl" class="cn.csdn.hr.s2sh.service.AdminServiceImpl">

<property name="adminDao" ref="adminDao"></property>

</bean>

</beans>

上面的ref是adminDaoImpl，在beans-dao.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<!-- hibernatedao的模板类 HibernateDaoSuppor 抽象类不可以实例化 加上abstract="true" -->

<bean id="hibernateDaoSupport"

class="org.springframework.orm.hibernate3.support.HibernateDaoSupport"

abstract="true">

<property name="sessionFactory" ref="sessionFactory"></property>

</bean>

<!-- admin的dao对象 -->

<bean id="adminDao" class="cn.csdn.hr.s2sh.dao.AdminDaoImpl"

parent="hibernateDaoSupport" />

</beans>

然后我们把上面的三个beans.xml导入到applicationContext.xml中

<!-- 导入其他的配置文件 -->

<import resource="beans-dao.xml" />

<import resource="beans-service.xml" />

<import resource="beans-action.xml" />

7．配置web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">

<display-name>s2sh</display-name>

<welcome-file-list>

<welcome-file>index.html</welcome-file>

<welcome-file>index.htm</welcome-file>

<welcome-file>index.jsp</welcome-file>

<welcome-file>default.html</welcome-file>

<welcome-file>default.htm</welcome-file>

<welcome-file>default.jsp</welcome-file>

</welcome-file-list>

<!-- 指定spring的配置文件，默认从web根目录寻找配置文件，我们可以通过spring提供的classpath:前缀指定从类路径下寻找 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applic*.xml</param-value>

</context-param>

<!-- 对Spring容器进行实例化 -->

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<!-- struts2 的配置 -->

<filter>

<filter-name>struts2</filter-name>

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<!-- 配置 使用spring解决hibernate因session关闭导致的延迟加载例外问题 -->

<filter>

<filter-name>OpenSessionInViewFilter</filter-name>

<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>

<init-param>

<!-- 指定org.springframework.orm.hibernate3.LocalSessionFactoryBean在spring配置文件中的名称,默认值为sessionFactory.如果LocalSessionFactoryBean在spring中的名称不是sessionFactory,该参数一定要指定,否则会出现找不到sessionFactory的例外 -->

<param-name>sessionFactoryBeanName</param-name>

<param-value>sessionFactory</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>OpenSessionInViewFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<!-- 使用spring解决struts2的中文乱码的问题 -->

<filter>

<filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encoding</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

</web-app>

8．我们来做一个简单的登入，使用的jsp页面为：

<body>

<div>

<form action="/s2sh/csdn/loginAdmin.action" method="get">

用户名：<input type="text" name="admin.name"/><br/>

密 码：<input type="password" name="admin.pass"/><br/>

<input type="submit" value="登入"/>

<input type="reset" value="重置"/>

</form>

</div>

<div>

用户名为:${admin.name}

</div>

</body>

访问到的action的处理为：

package cn.csdn.hr.s2sh.action;

import cn.csdn.hr.s2sh.domain.Admin;

import cn.csdn.hr.s2sh.service.AdminService;

import com.opensymphony.xwork2.ActionSupport;

public class AdminAction extends ActionSupport {

private static final long serialVersionUID = 1L;

private AdminService adminService;

private Admin admin;

public Admin getAdmin() {

return admin;

}

public void setAdmin(Admin admin) {

this.admin = admin;

}

// 注入

public void setAdminService(AdminService adminService) {

this.adminService = adminService;

}

public String login() {

System.out.println("用户名:" + admin.getName());

admin = adminService.login(admin.getName(), admin.getPass());

return SUCCESS;

}

}
