创建名称为bean的错误：当前线程的作用域“请求”未激活 [英] Error creating bean with name : Scope 'request' is not active for the current thread

问题描述

我已经集成了SWF 2.2.1，Primefaces 2.2.1，JSF 2，Spring Security 3，Spring 3.1.0M1I和EhCache以及AspectJ和Castor。

I have integrated SWF 2.2.1,Primefaces 2.2.1,JSF 2,Spring Security 3,Spring 3.1.0M1I and EhCache and AspectJ and Castor.

I在我的app-config.xml中为Castor定义了bean，例如

I have defined beans for castor in my app-config.xml like

<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，可在其中构建

I have a search page from where I am building the parameters like

<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函数并传递ACORD（使用的层次结构建立xml）物件。该OXMapper类分别负责对象和xml的编组和解组。

Using Spring Webflow, I am calling the OXMapper functions and passing the ACORD(hierarchical structural as it is used to build xml) object to it. This OXMapper class is responsible for marshalling and unmarshalling of the object and xml respectively.

现在的问题是，每当我再次在搜索页面上进行搜索时，旧值就会自动填充到字段。

Now the problem is whenever I am searching again on search page , old values automatically populates inside the fields.

所以我尝试将范围更改为请求 。

So I tried changing the scope to "Request".

<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，出现以下错误：

After changing the scope I get the following error:

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

我的面孔-config.xml没有这样的东西

My faces-config.xml has nothing as such

<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 -->

推荐答案

如果您不使用Spring MVC，则要使用 request 范围，必须引用 RequestContextListener 在您的web.xml中：

If you are not using Spring MVC, in order to use the request scope, you must reference the RequestContextListener in your web.xml:

f使用Servlet 2.4+网络容器，并在Spring的DispatcherServlet外部处理请求（例如，使用JSF或Struts时），您需要将以下javax.servlet.ServletRequestListener添加到Web应用程序web.xml文件中的声明中：

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>
