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

- <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>

- </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
