找不到带有 URI 的 HTTP 请求的映射 - 使用 Spring WebFlow 的 JSF 资源

Question

我正在尝试使用 JSF (Primefaces 3.1.1) 和 Spring WebFow 2.3 设置一个 Web 项目。我能够部署和启动我的索引页面，但我注意到 p:commandButton 似乎没有 Primeface 的外观和感觉。

当我启动应用程序时，我在 IDE 控制台上看到以下警告：

WARNING: No mapping found for HTTP request with URI [/client-ui/contact/javax.faces.resource/primefaces.css] in DispatcherServlet with name 'DispatcherMVC'
WARNING: No mapping found for HTTP request with URI [/client-ui/contact/javax.faces.resource/theme.css] in DispatcherServlet with name 'DispatcherMVC'
WARNING: No mapping found for HTTP request with URI [/client-ui/contact/javax.faces.resource/primefaces.js] in DispatcherServlet with name 'DispatcherMVC'
WARNING: No mapping found for HTTP request with URI [/client-ui/contact/javax.faces.resource/jquery/jquery.js] in DispatcherServlet with name 'DispatcherMVC'

Answer 1

BalusC 的 cmets 是正确的，但是即使您遵循他的建议，您仍然可能会遇到 Primefaces 组件无法正确渲染的问题。您尚未在 web.xml 中映射 Primefaces 资源 Servlet。

<servlet>
  <servlet-name>Resource Servlet</servlet-name>
  <servlet-class>org.primefaces.resource.ResourceServlet</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>Resource Servlet</servlet-name>
  <url-pattern>/primefaces_resource/*</url-pattern>
</servlet-mapping>

此 servlet 名称与您的 WebFlow 资源 servlet 的 Servlet 名称冲突，因此您还需要解决此名称差异。

Answer 2

正如spring show case sample中所述：

启用对 JSF 2 资源请求的处理。例如：

/webflow-primefaces-showcase/app/javax.faces.resource/jsf.js?ln=javax.faces

尝试将此添加到您的 MVC 配置中：

    <faces:resources/>

在某些情况下，声明了多个资源，也有必要使用显式 order 属性。例如：

    <mvc:resources mapping="/resources/**" location="/"/>
    <faces:resources order="-1"/>

Answer 3

我为我的应用解决了这个问题

在 WEB-INF/config/webmvc-config.xml 中将 order 0 设置为 mvc:resources

<mvc:resources order="0" location="/WEB-INF/web-content/" mapping="/WEB-INF/web-content/**"/>

然后在 WEB-INF/config/webflow-config.xml 中将 FlowHandlerMappin 的 order 值更改为更大的值：

<bean class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping"> 
    <property name="order" value="2" /> 
    <property name="flowRegistry" ref="flowRegistry" /> 
</bean>

这就足够了，但我建议你也从 web.xml 中删除 ResourceServlet，mvc:resources 不再需要它了
