Camel CXF:使用CXFOutInterceptor压缩响应会引发classcast异常

我有一个服务包,我想通过使用CXF GZIPFeature来压缩响应。该捆绑包部署在JBoss Fuse(jboss-fuse-6.1.0.redhat-379)上。骆驼路线配置是:

<cxf:bus id="cxf" name ="cxf">
    <cxf:features>
        <bean class="org.apache.cxf.transport.common.gzip.GZIPFeature">
            <property name="threshold">
                <value>1</value>
            </property>
        </bean>
    </cxf:features>
</cxf:bus>

<camel:camelContext ...>
    <camel:route id="test-server">
        <camel:to uri="cxfbean:servicebeans?bus=#cxf&amp;providers=#providers" />
    </camel:route>
</camel:camelContext>

但这会抛出一个classcast异常:

java.lang.ClassCastException: org.apache.cxf.transport.common.gzip.GZIPOutInterceptor$GZipThresholdOutputStream cannot be cast to org.apache.cxf.io.CachedOutputStream
at org.apache.camel.component.cxf.transport.CamelDestination$CamelOutputStream.commitOutputMessage(CamelDestination.java:284)[204:org.apache.camel.camel-cxf-transport:2.12.0.redhat-610379]

在路线中使用CXF GZIPFeature是否合法?我不想使用Camel的DataFormat进行gzip。

1 个答案:

答案 0 :(得分:0)

我正在使用servicemix-camel-cxf并且遇到了几乎相同的问题。最后,我决定简单地将其添加到路线中:

<marshal> <gzip/> </marshal>

检查出来 - 也许它对你有帮助。 但在这种情况下,您必须设置Content-Type: gzip标题。

尝试添加

<setHeader headerName="Content-Type">
    <constant>gzip</constant></setHeader>

但是对我来说没有用,所以我在java代码中添加了标题。 =)
