ssh框架搭建详解编程语言

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

[html]
view plain
copy

<?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

[html]
view plain
copy

<?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

[html]
view plain
copy

<?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

[html]
view plain
copy

<?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

[html]
view plain
copy

<?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

[java]
view plain
copy

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
