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";
    }

}
