我集成了SWF 2.2.1,Primefaces 2.2.1,JSF 2,Spring Security 3,Spring 3.1.0M1I和EhCache以及AspectJ和Castor.

我在app-config.xml中为castor定义了bean

<bean id="oXMapper" class="com.abc.xyz.util.OXMapper">
    <property name="unmarshaller" ref="unmarshaller" />
    <property name="marshaller" ref="marshaller" />
    <property name="acordRequest" ref="acordRequest" />
    <property name="acordResponse" ref="acordResponse" />
</bean>

<bean id="unmarshaller" class="org.springframework.oxm.castor.CastorMarshaller">
    <property name="mappingLocation"
        value="classpath:/templates/mapping/ACORD_Response_Mapping.xml" />
</bean>

<bean id="marshaller" class="org.springframework.oxm.castor.CastorMarshaller">
    <property name="mappingLocation"
        value="classpath:/templates/mapping/ACORD_Request_Mapping.xml" />
</bean>

<bean id="acordRequest" class="com.abc.xyz.cate.domain.ACORD">
    <property name="insuranceSvcRq" ref="insuranceSvcRq" />
    <property name="signonRq" ref="CltSearch_signonRq" />
</bean>

我有一个搜索页面,我在这里建立参数,如

<h:panelGrid>
    <h:selectOneRadio id="#{msg.srchType}" value="#{acordRequest.insuranceSvcRq.com_csc_ClientSearchRq.com_csc_SearchInfo.com_csc_SearchCriteria.com_csc_ClientSearch.com_csc_SearchNameByType}">
        <f:selectItem itemLabel="#{msg.exact}" itemValue="E" id="#{msg.exact}" />
    <f:selectItem itemLabel="#{msg.phonetic}" itemValue="S" id="#{msg.phonetic}" />
    <f:selectItem itemLabel="#{msg.truncated}" itemValue="P" id="#{msg.truncated}" />
        </h:selectOneRadio>
</h:panelGrid>

使用Spring Webflow,我调用OXMapper函数并将ACORD(用于构建xml的分层结构)对象传递给它.此OXMapper类分别负责对象和xml的编组和解组.

现在问题是每当我在搜索页面上再次搜索时,旧值会自动填充在字段内.

所以我尝试将范围更改为“请求”.

<bean id="acordRequest" class="com.abc.xyz.cate.domain.ACORD"
    scope="request">
    <property name="insuranceSvcRq" ref="insuranceSvcRq" />
    <property name="signonRq" ref="CltSearch_signonRq" />
</bean>

更改范围后,我收到以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'oXMapper' defined in ServletContext resource [/WEB-INF/config/app-config.xml]: Cannot resolve reference to bean 'acordRequest' while setting bean property 'acordRequest'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'acordRequest': Scope 'request' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

我的web.xml如下

我的faces-config.xml没有这样的东西

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">

<application>
    <!-- <message-bundle>JsfMessageResources</message-bundle> -->
</application>
<!-- JSF 2.0 Version of this faces-config.xml file -->

解决方法:

如果您不使用Spring MVC,那么为了使用请求范围,您必须在web.xml中引用RequestContextListener：

f you use a Servlet 2.4+ web container, with requests processed outside of Spring’s DispatcherServlet (for example, when using JSF or Struts), you need to add the following javax.servlet.ServletRequestListener to the declarations in your web applications web.xml file:

<web-app>
...
<listener>
  <listener-class>
      org.springframework.web.context.request.RequestContextListener
  </listener-class>
</listener>
...
</web-app>
