与 DWR 集成时，我遇到了 spring MVC 映射问题。问题是，我不能让他们一起工作。我想在我的 jsp 中使用 dwr 服务，但是当 dwr 映射工作时，spring 不会，相反。

web.xml

         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/dwr/*</url-pattern>
    </servlet-mapping>

    <servlet-mapping>

    </servlet-mapping>


    <listener>
        <listener-class>
            SpringListeners.MySessionListener
        </listener-class>
    </listener>
    <session-config>
        <session-timeout>1</session-timeout>
    </session-config>

</web-app>

        <property name="suffix" value=".jsp"/>
    </bean>


    <dwr:controller id="dwrController" debug="true">
        <dwr:config-param name="activeReverseAjaxEnabled" value="true"/>
        <dwr:config-param name="scriptCompressed" value="true"/>
        <dwr:config-param name="fileUploadMaxBytes" value="10485760"/>
        <dwr:config-param name="allowScriptTagRemoting" value="true"/>
    </dwr:controller>


    <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="alwaysUseFullPath" value="true"/>
        <property name="mappings">
            <props>
                <prop key="/dwr/**/*">dwrController</prop>
            </props>
        </property>
    </bean>



    <bean id="Player" class="dwr.Player" scope="session">
        <dwr:remote javascript="Player">
            <!--<dwr:include method="" />-->
        </dwr:remote>
        <aop:scoped-proxy proxy-target-class="false"/>
    </bean>

</beans>

现在 dwr 在调试模式下工作，但所有其他 spring 映射都没有。当我删除

<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
            <property name="alwaysUseFullPath" value="true"/>
            <property name="mappings">
                <props>
                    <prop key="/dwr/**/*">dwrController</prop>
                </props>
            </property>
        </bean>

dwr 不起作用，但 spring 映射可以。这是我用于测试弹簧映射的控制器

@Controller
@RequestMapping("/")
public class HelloController {
    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {
        System.out.println("agaga");
        model.addAttribute("message", "Hello world!");

        return "hello";
    }
}
