SSH搭建

　　1、首先在lib中导入ssh需要的jar包：

如图：



2、其次配置web.xml (在WEB-INF目录下)

<?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/j2ee"
xmlns:web="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_9" version="2.4">
<!-- struts2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>

<!-- Spring 配置  Spring应用程序上下文监听器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>

<!--首页面设置  -->
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>

3、配置applicationContext.xml

<?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:p="http://www.springframework.org/schema/p"
xmlns:tx="http://www.springframework.org/schema/tx"

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

">
<!-- 启用spring注解支持
<context:annotation-config />-->

<!--配数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/yan" />
<property name="username" value="root" />
<property name="password" value="root" />
</bean>

<!--实例化sessionFactory  -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>

<property name="mappingResources">
<list>
<value>bean/User.hbm.xml</value>
<value>bean/CalendarEvent.hbm.xml</value>
</list>
</property>

</bean>

<bean id="dbhelper" class="util.DBHelper">
<constructor-arg ref="sessionFactory"></constructor-arg>
</bean>

<bean id="userdao" class="dao.UserDao" parent="dbhelper"></bean>
<bean id="calendardao" class="dao.CalendarEventDao" parent="dbhelper"></bean>

<!--Spring 实例化action  -->
<bean id="loginaction" class="action.LoginAction" scope="prototype" ></bean>
<bean id="registeraction" class="action.RegisterAction" scope="prototype">
<property name="dao" ref="userdao"></property>
</bean>
<bean id="calendaraction" class="action.CalendarEventAction" scope="prototype">
<property name="dao" ref="calendardao"></property>
</bean>
</beans>

4.配置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>
<!-- 应用Spring管理Struts action  -->
<constant name="struts.objectFactory" value="spring"></constant>

<constant name="struts.devMode" value="true" />
<!-- 当struts的配置文件修改后,系统是否自动重新加载该文件,默认值为false(生产环境下使用),开发阶段最好打开 -->
<constant name="struts.configuration.xml.reload" value="true" />

<package name="default" extends="struts-default">
<action name="registerAction" class="registeraction">
<result name="success">/success.jsp</result>
<result name="input">/register.jsp</result>
</action>

<action name="LoginAction" class="loginaction">
<result name="success">/show/index.jsp</result>
<result name="input">/login.jsp</result>
</action>

<action name="fileUpload" class="action.FileUploadAction">
<result name="success">/FileUpload.jsp</result>
</action>
</package>

<!-- ajax请求的action url是calendarAction_方法名 -->
<package name="datalist" extends="struts-default,json-default">
<action name="calendarAction_*" class="calendaraction" method="{1}"> <!-- class的值 是 bean的id -->
<result type="json">
<param name="root">list</param>  <!-- list 通过set，get方法返回 -->
</result>
</action>
</package>
</struts>

5、这两个配置文件都放在src目录下

如图：



6、CalendarEventAction.java

public class CalendarEventAction extends ActionSupport {

/**
*
*/
private static final long serialVersionUID = 1L;
private CalendarEvent event;
private CalendarEventDao dao;
private List<CalendarEvent> list;

public List<CalendarEvent> getList() {
return list;
}

public void setList(List<CalendarEvent> list) {
this.list = list;
}

/*public CalendarEventDao getDao() {
return dao;
}
*/
public void setDao(CalendarEventDao dao) {
this.dao = dao;
}

public CalendarEvent getEvent() {
return event;
}

public void setEvent(CalendarEvent event) {
this.event = event;
}

public String insertCalendar(){
HttpServletRequest request=    ServletActionContext.getRequest();
HttpServletResponse response=ServletActionContext.getResponse();

try {
request.setCharacterEncoding("utf-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
response.setContentType("text/json; charset=utf-8");
boolean flag=dao.insetCalendarEvent(event);
try {
PrintWriter out = response.getWriter();
out.print(flag);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return null;
}

public String getCalendar(){

list=dao.getCalendarEvent();

return "success";
}

}
