Spring MVC

web.xml 配置：

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:config/spring.xml;
        classpath:config/spring-mybatis.xml;
        classpath:config/spring-shiro.xml;
        classpath:config/activiti.cfg.xml;
    </param-value>
  </context-param>

  <listener>
    <description>spring监听器</description>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

此配置是使用 ContextLoaderListener 告诉他Spring 配置文件的位置。
监听器是 配置上下文载入器、此载入器是是载入除了DispacherServlet 载入的配置文件的其他上下文配置文件

<servlet>
    <description>spring mvc servlet</description>
    <servlet-name>springMvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

      <param-value>classpath:config/spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>

<context:component-scan/> 扫描指定的包中的类上的注解，常用的注解有：

@Controller 声明Action组件
@Service 声明Service组件 @Service("myMovieLister")
@Repository 声明Dao组件
@Component 泛指组件, 当不好归类时.
@RequestMapping("/menu") 请求映射
@Resource 用于注入，( j2ee提供的 ) 默认按名称装配，@Resource(name="beanName")
@Autowired 用于注入，(srping提供的) 默认按类型装配
@Transactional( rollbackFor={Exception.class}) 事务管理
@ResponseBody
@Scope("prototype") 设定bean的作用域
