让Dwr和Spring-MVC通过Annotation方式共同工作

引用

SPRING2.X后引入了@Controller的方式标注Controller，大大简化了原来的XML方式的MVC配置，不过传统的DWR配置方式，虽然可以通过SpringCreator的方式将BEAN暴露给AJAX使用，但是仍然逃不出繁杂的XML配置，通过SPRING的annotation方式，可以简化DWR和SPRING之间的配置. 

web.xml 

<!-- Spring -->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                classpath:spring/webControllerContext.xml
            </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>*.htm</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/dwr/*</url-pattern>
    </servlet-mapping>

将DispatcherServlet配置成管理htm和dwr
