s2sh整合

一. 導包

框架的版本情況：Struts2.3.4 + hibernate3.6.0+spring3.2.5
有一些是非必需的，只不過為了功能的完整性，就全部都弄過去了,比如導出Word，Excel，還有文件上傳，日志等。

二. 配置web.xml

<code>
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<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>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:bean.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
</code>

三.寫applicationContext.xml

<code>

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssh_demo"></property>
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="user" value="root"></property>
<property name="password" value="root"></property>
<property name="initialPoolSize" value="3"></property>
<property name="maxPoolSize" value="6"></property>
</bean>


<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<property name="mappingLocations">
<list>
<value>classpath:com/ycTime/entity/.hbm.xml</value>
</list>
</property>
</bean>

<context:component-scan base-package="com.ycTime.action"> </context:component-scan>
<context:component-scan base-package="com.ycTime.service"></context:component-scan>
<context:component-scan base-package="com.ycTime.dao"></context:component-scan>


<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="get" read-only="true"/>
<tx:method name="find" read-only="true"/>
<tx:method name="" read-only="false"/>
</tx:attributes>
</tx:advice>

<aop:config>
<aop:pointcut expression="execution(* com.ycTime.service.impl..(..))" id="pt"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
</aop:config>
</code>

四.寫entity

  • Notice.java
    <code>
    public class Notice {
    private int id;
    private String title;
    private String content;
    private Date doTime;
    private int status;// 0表示是草稿，1表示是已經發布
    public int getStatus() {
    return status;
    }
    public void setStatus(int status) {
    this.status = status;
    }
    public int getId() {
    return id;
    }
    public void setId(int id) {
    this.id = id;
    }
    public String getTitle() {
    return title;
    }
    public void setTitle(String title) {
    this.title = title;
    }
    public String getContent() {
    return content;
    }
    public void setContent(String content) {
    this.content = content;
    }
    public Date getDoTime() {
    return doTime;
    }
    public void setDoTime(Date doTime) {
    this.doTime = doTime;
    }
    }
    </code>

  • Notice.hbm.xml
    <code>
    <?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="com.ycTime.entity">
    <class name="Notice" table="usad_Notice">
    <id name="id" column="id">
    <generator class="native"></generator>
    </id>
    <property name="title" column="title"></property>
    <property name="content" column="content"></property>
    <property name="doTime" column="doTime"></property>
    <property name="status" column="status"></property>
    </class>
    </hibernate-mapping>
    </code>

五. 寫Dao

其中，@Repository是spring注解，上文中applicationContext.xml的掃描那部分，就是和這里配合的，配置了掃描之后，spring在加載applicationContext.xml的時候就會自動掃描帶注解的類并在spring容器中創建相關的實例，以及完成依賴注入。@Repository是持久層注解，@Autowired是自動注入，NoticeDao就注入了SessionFactory。
<code>
@Repository
public class NoticeDao {
@Autowired
private SessionFactory sessionFactory;
public boolean saveNotice(Notice notice){
Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();
try {
transaction.begin();
session.saveOrUpdate(notice);
transaction.commit();
} catch (Exception e) {
transaction.rollback();
return false;
}finally {
session.close();
}
return true;
}
}
</code>

六.寫Service

也是用了注解，類似
<code>
@Service
public class NoticeService {
@Autowired
private NoticeDao noticeDao;
public boolean saveNotice(String title, String content, Date doTime) {
Notice notice = new Notice();
notice.setContent(content);
notice.setDoTime(doTime);
notice.setTitle(title);
notice.setStatus(0);
boolean b = noticeDao.saveNotice(notice);
return b;
}
}
</code>

七. 寫action

<code>
@Controller
public class NoticeAction {
@Autowired
private NoticeService noticeService;
public String addNotice(){
HttpServletRequest request = ServletActionContext.getRequest();
String title = request.getParameter("title");
String content = request.getParameter("content");
boolean b = noticeService.saveNotice(title,content,new Date());
if(b == true){
return "success";
}
reutrn "error";
}
}
</code>

八. 寫Struts配置文件

Struts.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.i18n.encoding" value="UTF-8" />
<constant name="struts.configuration.xml.reload" value="true"/>
<constant name="struts.action.extension" value="action,,"></constant>
<include file="com/ycTime/config/*Struts.xml"></include>
</struts>

控制跳轉的struts配置文件 NoticeStruts.xml:
<code><?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="noticeAction" namespace="/" extends="struts-default">
<action name="addNotice" class="com.ycTime.action.NoticeAction" method="addNotice">
<result name="success">success.jsp</result>
<result name="error">error.jsp</result>
</action>
</package>
</struts></code>

九.寫jsp頁面

<code><form action="${pageContext.request.contextPath }/addNotice.action">
標題:<input name="title" type="text">

內容:<input name="content" type="text">

<input type="submit">
</form>
</code>

至此，ssh整合完成。
