Spring webflow 2 - url映射不起作用

Question

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

我在下面粘贴了我的servlet-context.xml.

非常感谢您的帮助!欧弟

servlet_context.html的版本,只有一个视图解析器(jstl view reolver).mvc和webflow部件都不适用于此设置.

Answer 1

尝试将您FlowHandlerMapping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HandlerMapping为您注册了一个默认值,我怀疑它不会落入下一个HandlerMapping.这在以前被报道为一个问题.您希望WebFlow FlowHandlerMapping先到 - 所以您将顺序设置为-1.这就是我们在配置中所拥有的.
