String相关配置一
?1、启动Web容器时，自动装配ApplicationContext的配置信息
?<listener>
??? <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
??? </listener>
? <listener>
?
或：
<servlet>
??? <servlet-name>context</servlet-name>
???? ?<servlet-class>
??????? ?org.springframework.web.context.ContextLoaderServlet
???? ?</servlet-class>
??? <load-on-startup>1</load-on-startup>
</servlet>
?
2、需要指定配置文件位置，可通过context-param加以指定：可以逗号分隔多多文件
?
?<context-param>
??<param-name>contextConfigLocation</param-name>
??<param-value>classpath*:spring/applicationContext.xml, /WEB-INF/MenuTrees.xml</param-value>
?</context-param>
?
?
3、
WebApplicationContextUtils.getWebApplicationContext方法在Web应用中获取ApplicationContext引用。 如：ApplicationContext ctx=WebApplicationContextUtils.getWebApplicationContext();
???????? LoginAction action=(LoginAction)ctx.getBean("LoginAction ");
?
?ServletContext servletContext = request.getSession().getServletContext();???
??????? ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext);
??????? return (DailyBalanceService) ctx.getBean("balanceService");
?
4、spring-mvc 的相关配置
?1、配置请求分发：
??? <servlet>
??????? <servlet-name>dispatcher</servlet-name>
??????? <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
??????? <init-param>
??????????? <param-name>contextConfigLocation</param-name>
??????????? <param-value>/WEB-INF/mvc-config/*.xml</param-value>
??????? </init-param>
??????? <load-on-startup>1</load-on-startup>
??? </servlet>
?
⑵
?<servlet-mapping>???????????????????????
??????? <servlet-name>Dispatcher</servlet-name>
??????? <url-pattern>*.do</url-pattern>
</servlet-mapping>
?
说明：1、DispatcherServlet 根据配置将请求分发给各逻辑处理单元；
???????? 2、请求映射 ，.do, .action等；
?
响应bean
?
??? <bean id="viewResolver" value="redirect:/Cart/ShowCart.do"/>
??? <property name="errorView" value="feifei/Cart/ShoppingCart"/>
??? <property name="presentRuleManager" ref="PresentRuleManager"/>
??? <property name="frontEnd" value="true"/>
? </bean>
?
或者：
1、?<bean id="urlMappingDocument"??? value="redirect:/Cart/ShowCart.do"/>
??? <property name="errorView" value="feifei/Cart/ShoppingCart"/>
??? <property name="presentRuleManager" ref="PresentRuleManager"/>
??? <property name="frontEnd" value="true"/>
? </bean>
?
