实现简单的添加股票功能
导入jar包:
创建实体类:
数据访问层接口及其实现
创建service
配置ApplicationContext.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd "> <!-- 01.C3p0 数据源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <!-- 设值注入,本质上使用的是类的set方法 --> <property name="driverClass" value="${jdbc.driver}"></property> <property name="jdbcUrl" value="${jdbc.url}"></property> <property name="user" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!-- 方式二:找到jdbc.peroperties文件 --> <context:property-placeholder location="classpath:jdbc.properties"/> <!-- 1.1 SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" ></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate3.SpringSessionContext</prop> </props> </property> <property name="mappingLocations" value="classpath:cn/happy/beans/Stock.hbm.xml"></property> </bean> <!-- dao --> <bean id="stockDao" class="cn.happy.dao.impl.StockDAOImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- service --> <bean id="service" class="cn.happy.service.impl.StockServiceImpl"> <property name="dao" ref="stockDao"></property> </bean> <!-- action --> <bean id="stockAction" class="cn.happy.action.StockAction"> <property name="service" ref="service"></property> </bean> <!-- 事务;能让多个操作做为一个整体,同生共死 荣辱与共 DataSourceTransactionManager--> <!-- 01.事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <!-- 必须配置数据源 --> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 第三种:AspectJ AOP 配置事务 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="save*" isolation="DEFAULT" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <!-- 具体的AOP --> <aop:config> <aop:pointcut expression="execution(* *..service.*.*(..))" id="pointCut"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/> </aop:config> </beans>
配置数据库连接信息
创建struts.xml
因为是web端:所以要配置web.xml来加载资源文件
<?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/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name></display-name> <!--指定路径 applicationContext.xml --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 监听器:在应用程序加载启动的时候,spring容器自动构建 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 核心过滤器 --> <filter> <filter-name>struts</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
最后创建页面进行访问:
add.jsp
成功页面:
index.jsp
