ssh框架搭建

目录结构：

一、新建web project

二、在src目录下新建struts.xml  ，使用include是为了方便分开各个action

<?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>
    <!-- 指定Web应用的默认编码集,相当于调用HttpServletRequest的setCharacterEncoding方法 -->
    <constant name="struts.i18n.encoding" value="UTF-8" />
    <!-- 设置浏览器是否缓存静态内容,默认值为true(生产环境下使用),开发阶段最好关闭 -->
    <constant name="struts.serve.static.browserCache" value="false" />
    <!-- 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" />
    <!-- 开发模式下使用,这样可以打印出更详细的错误信息 -->
    <constant name="struts.devMode" value="true" />
    <include file="admin.xml" />

</struts>

还有admin.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>
    <package name="admin"  extends="struts-default">
       <action name="admin_*" class="adminAction" method="{1}">
             <result name="login">
               /backend/main.jsp   <!-- 页面跳转 -->
            </result>
             <result name="delSuc" type="redirectAction">
               <param name="actionName">admin_login</param> <!-- action跳转 -->
            </result>

        </action>
    </package>
</struts>

三、在src目录增加hibernate.cfg.xml

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration>

    <session-factory>
        <mapping resource="com/d3/d3studio/model/Admin.hbm.xml" />

    </session-factory>

</hibernate-configuration>

四、在WEB-INF增加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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

    xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-3.0.xsd
            http://www.springframework.org/schema/aop
            http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
            http://www.springframework.org/schema/tx
            http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
            ">

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 指定连接数据库的JDBC驱动 -->
        <property name="driverClass">
            <value>com.mysql.jdbc.Driver</value>
         </property>
        <!-- 连接数据库所用的URL -->
        <property name="jdbcUrl">
            <value>jdbc:mysql://localhost:3306/pacs</value>
        </property>
        <!-- 连接数据库的用户名 -->
        <property name="user">
            <value>root</value>
        </property>
        <!-- 连接数据库的密码 -->
        <property name="password">
            <value>root</value>
        </property>
        <!-- 设置数据库连接池的最大连接数 -->
        <property name="maxPoolSize">
            <value>20</value>
        </property>
        <!-- 设置数据库连接池的最小连接数 -->
        <property name="minPoolSize">
            <value>2</value>
        </property>
        <!-- 设置数据库连接池的初始化连接数 -->
        <property name="initialPoolSize">
            <value>2</value>
        </property>
        <!-- 设置数据库连接池的连接的最大空闲时间,单位为秒 -->
        <property name="maxIdleTime">
            <value>20</value>
        </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.MySQLDialect</prop>
                 <prop key="hibernate.show_sql">true</prop>
                 <prop key="hibernate.fromat_sql">true</prop>
                 <prop key="hibernate.generate_statistics">true</prop>
                 <prop key="hibernate.connection.release_mode">auto</prop>
                 <prop key="hibernate.autoReconnect">true</prop>
                 <prop key="hibernate.cache.use_query_cache">true</prop>
                 <prop key="cache.use_second_level_cache">true</prop>
                 <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>

             </props>
         </property>
        <property name="mappingResources">
            <list>
                <value>com/d3/pacs/model/Admin.hbm.xml</value>         <-- 对应model包里的映射 -->
            </list>
        </property>
    </bean>


    <bean id="txManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <tx:annotation-driven transaction-manager="txManager" />
    <-- 使用spring的注入  -->
    <bean id="adminDAO" class="com.d3.pacs.dao.AdminDAO">
    <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    <bean id="adminService" class="com.d3.pacs.service.AdminService">
        <property name="adminDAO" ref="adminDAO" />
    </bean>
    <bean id="adminAction" class="com.d3.pacs.action.AdminAction" scope="prototype">
        <property name="adminService" ref="adminService" />
    </bean>

</beans>

五、web.xml需要修改

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
    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_3_0.xsd">
  <display-name></display-name>
    <!-- 配置struct2-->
    <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>

    <!-- 启动Spring容器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 默认启动项 -->
  <welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
  </welcome-file-list>
</web-app>

六、编写action

public class AdminAction extends ActionSupport {
    private static Logger logger = Logger.getLogger(AdminAction.class);
    private AdminService adminService;
    private Admin admin;

    public AdminService getAdminService() {
        return adminService;
    }

    public void setAdminService(AdminService adminService) {
        this.adminService = adminService;
    }

    public Admin getAdmin() {
        return admin;
    }

    public void setAdmin(Admin admin) {
        this.admin = admin;
    }

    // 管理员登陆
    public String login() {
        if(adminService.login(admin) !=null){
            HttpServletRequest request = ServletActionContext.getRequest();
            HttpSession session = request.getSession(true);
            session.setAttribute("admin1", admin);
            return "login";
        }
        else
            return "loginFail";
    }

    // 管理员注册
    public String regist() {
        return "regist";
    }

    // 退出管理员
    public String exit() {
        HttpServletRequest request = ServletActionContext.getRequest();
        request.getSession().removeAttribute("admin1");
        return "exit";
    }
}

七、   访问流程： 在jsp中提交action    提交表单<form id="login" action="/my/admin_login" method="post">    

/my是我的tomcat自己定义的虚拟目录，   admin_* 对应的是admin.xml中 <action name="admin_*" class="adminAction" method="{1}">

访问admin_login  对应的就是action类中的public String login()的方法 ，根据此方法返回的String 

对应的也是admin.xml 中 ，返回login则会跳刀main.jsp

<result name="login">        
               /backend/main.jsp   <!-- 页面跳转 -->
            </result>
             <result name="regist">        
               /backend/main.jsp   <!-- 页面跳转 -->
            </result>
             <result name="delSuc" type="redirectAction">  
               <param name="actionName">admin_login</param> <!-- action跳转 -->
            </result>

另外，struts会自动匹配类属性和jsp中name

比如： 

jsp里面有  ：  <INPUT class=TxtUserNameCssClass maxLength=20 name="name">

对应在action里面，如果有name的属性，只要提供get，set方法，那么jsp中的name就会传到action

另外还可以：    <INPUT class=TxtUserNameCssClass maxLength=20 name="admin.name">

对应action里面有个admin的类属性且 admin有name属性， 则会赋值
