SSH整合

SSH整合

    最近没怎么手头上没什么事情，不过我感觉也是好事，毕竟一直忙碌刀会钝的。

所有最近收刀，静心磨刀，不为外面的什么各种项目所迷惑。收收心，毕竟磨刀不误砍柴工。总结下Spring整合Struts2和Hibernate。

    上篇总结了Spring整合Struts2这次我把Hibernate加了进来，Spring这个非常强大的框架也是真真正正的算得上有个有艺术品位的框架，IOC和AOP完美结合，不仅仅可以用在WEB上面在其他的平台下运用也是非常的广泛。

   下面开始做帖代码,这个例子实现了一个登陆和注册模块，用SSH做的一个简单的整合。

第一步建好一个web工程后添加jar包：

然后在WEB-INF下面创建applicationContext.xml用来配置Spring容器：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
	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">
	<!-- 注册接口实现类 -->
	<bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
		<property name="url"
			value="jdbc:mysql://127.0.0.1:3306/test?characterEncoding=utf-8"></property>
		<property name="username" value="root"></property>
		<property name="password" value="root"></property>
	</bean>

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="datasource" />
		</property>
		<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>
			</props>
		</property>
		<property name="mappingResources">
			<list>
				<value>/com/zdx/domain/User.hbm.xml</value>
			</list>
		</property>
	</bean>
	<bean id="userDao" class="com.zdx.dao.impl.UserDaoImpl">
		<property name="sessionFactory">
			<ref bean="sessionFactory" />
		</property>
	</bean>

	<bean id="loginAction" class="com.zdx.action.LoginAction">
		<property name="service" ref="userService"></property>
	</bean>
	<bean id="userService" class="com.zdx.service.UserService">
		<property name="userDao" ref="userDao"></property>
	</bean>
</beans>

2.修改web.xml文件：

<?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"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	id="WebApp_ID" version="3.0">
	<display-name>Spring_Struts</display-name>

	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<!-- 
	listener是Servlet的监听器，他可以监听客户端的请求、服务器端的操作等，
	通过监听器，可以自动激发一些操作，如监听到在线的数量。当增加一个HttpSession时，
	就激发sessionCreated()方法。监听器需要知道application.xml配置文件的位置
	
	 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/applicationContext.xml</param-value>
	</context-param>

	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

src下面创建struts.properties:

struts.objectFactory=spring

src下面创建struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
	"http://struts.apache.org/dtds/struts-2.1.dtd">

<struts>
	<package name="default" extends="struts-default">
		<action name="loginAction_*" class="loginAction" method="{1}">
			<result name="success">/success.jsp</result>
			<result name="login">/index.jsp</result>
			<result name="registerError">/register.jsp</result>
		</action>
	</package>
</struts>

创建User.java:

package com.zdx.domain;

public class User {
	private Integer id;
	private String name;
	private String pwd;

	public User() {
		// TODO Auto-generated constructor stub
	}

	//get、set

}

 配置其hbm.xml如下：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping default-lazy="false">

	<class name="com.zdx.domain.User" table="user">
		<id name="id">
			<generator class="native"></generator>
		</id>
		<property name="name"></property>
		<property name="pwd"></property>
	</class>
</hibernate-mapping>

 然后创建UserDao接口，实现类UserDaoImpl如下：

package com.zdx.dao.impl;

import java.util.List;

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

import com.zdx.dao.UserDao;
import com.zdx.domain.User;

public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

	@Override
	public boolean insert(User user) {
		if (this.findByName(user.getName()) == null) {
			this.getHibernateTemplate().save(user);
			return true;
		}
		return false;
	}

	@Override
	public User findByName(String name) {
		User user = null;
		List<User> list = this.getHibernateTemplate().find(
				"from User where name=?", name);
		if (list.size() > 0) {
			user = list.get(0);
		}
		return user;
	}

}

 业务逻辑类UserService如下：

package com.zdx.service;

import com.zdx.dao.UserDao;
import com.zdx.domain.User;

public class UserService {

	private UserDao userDao;

	public boolean register(User user){
		return	this.userDao.insert(user);
	}
	
	public User login(User user){
		return this.userDao.findByName(user.getName());
	}
	
	
	public UserDao getUserDao() {
		return userDao;
	}

	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}

}

控制层LoginAction如下：

package com.zdx.action;

import com.opensymphony.xwork2.ActionSupport;
import com.zdx.domain.User;
import com.zdx.service.UserService;

public class LoginAction extends ActionSupport {
	private User user;
	private UserService service;

	@Override
	public String execute() throws Exception {
		// TODO Auto-generated method stub
		return super.execute();
	}

	public String login() {
		User userTmp = service.login(user);
		if (userTmp == null) {
			return LOGIN;
		} else if (this.user.getPwd().equals(userTmp.getPwd())) {
			return SUCCESS;
		}
		return LOGIN;
	}

	public String register() {
		if (service.register(user)) {
			return SUCCESS;
		} else {
			return "registerError";
		}
	}

	public User getUser() {
		return user;
	}

	public void setUser(User user) {
		this.user = user;
	}

	public UserService getService() {
		return service;
	}

	public void setService(UserService service) {
		this.service = service;
	}

}
