Spring webflow 2 - url映射不起作用

时间:2012-05-17 04:28:09

标签: spring spring-webflow url-mapping spring-webflow-2

我正在使用spring mvc 3和webflow 2.我一直在关注在线资源,并一直试图让一个例子正常工作。我无法使webflow url映射生效。只有网络流不工作,mvc部分工作正常。

我一直得到的错误是: 在名为“appServlet”的DispatcherServlet中找不到带有URI [/ Project2Admin / pizza]的HTTP请求的映射

我已粘贴下面的servlet-context.xml。

非常感谢您的帮助! 欧弟

版本的servlet_context.html只有一个视图解析器(jstl视图解析器)。 mvc和webflow部件都无法使用此设置。

尝试将FlowHandlerMapping更改为

<beans:bean
    class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
    <beans:property name="flowRegistry" ref="flowRegistry" />
    <beans:property name="order" value="-1" />
</beans:bean>

您正在使用Spring MVC的注释驱动配置,它为您注册一个默认的HandlerMapping,我怀疑它不会落入下一个HandlerMapping。此前已被报告为issue。您希望WebFlow FlowHandlerMapping成为第一个 - 因此您将顺序设置为-1。这就是我们在配置中所拥有的。

我设法通过为webflows创建调度程序servlet来解决问题。我不确定这是否是理想的解决方案,但它确实有效。 mvc和webflow现在都运行良好。

如果有人知道更优雅的方式来处理这个问题,即只使用一个调度程序servlet来处理mvc和webflow调用,请发表回复,非常感谢你的帮助。

谢谢!

我认为这里的问题是你的servlet-context.xml文件中有两个不同的视图解析器。

请删除 InternalResourceViewResolver ,并将viewClass,前缀和后缀属性放在 TilesViewResolver bean中。

据我说,这应该可以解决你的问题。

干杯。

对于我来说,WebFlow和Spring MVC的一切都很好用

这是我的web.xml的一部分:

<servlet>
    <servlet-name>web-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value></param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>web-dispatcher</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>web-dispatcher</servlet-name>
    <url-pattern>/public/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>web-dispatcher</servlet-name>
    <url-pattern>/error/*</url-pattern>
</servlet-mapping>

和我的网络调度员:

<bean id="viewNameTranslator" class="org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator" />

<bean id="basicViewResolver" class="org.springframework.web.servlet.view.ResourceBundleViewResolver" >
    <property name="basename" value="views"/> 
</bean>

<!-- Resolves logical view names returned by Controllers to Tiles; a view name to resolve is treated as the name of a tiles definition -->
<bean id="tilesViewResolver" class="org.springframework.js.ajax.AjaxUrlBasedViewResolver">
    <property name="viewClass" value="org.springframework.webflow.mvc.view.FlowAjaxTilesView"/>
</bean>

<!-- Configures the Tiles layout system -->
<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
    <property name="definitions">
        <list>
            <value>/WEB-INF/jsp/views.xml</value>
            <value>/WEB-INF/jsp/fragments/views.xml</value>
            <!-- Flow views -->
            <value>/WEB-INF/flows/**/views.xml</value>              
            <!-- PUBLIC Pages -->
            <value>/WEB-INF/jsp/public/views.xml</value>
        </list>
    </property>
</bean>

希望这会有所帮助
