java - Apache Camel Spring Ws 配置中的 PropertyAccessException

Question

我想配置 Spring-ws 连接管理器以使用 PoolingHttpClientConnectionManager。这是我的配置

camel-context.xml

<camel-context>
    <route>
        <from uri="direct:sampleCall"/>
        <to uri="bean:sampleCommand"/>
        <to uri="spring-ws:http://{{sample.uri}}?timeout={{sample.timeout}}&amp;messageSender=#messageSender&amp;soapAction=urn:MidwareWebServiceIntf-MidwareWebService#sampleCommand"/>
        <to uri="bean:xmlProcessor"/>
        <to uri="bean:validateResponse"/>
    </route>

    <route>
        <from uri="direct:anotherSampleCall"/>
        <to uri="bean:anotherSampleCommand"/>
        <to uri="spring-ws:http://{{anotherSample.uri}}?timeout={{anotherSample.timeout}}&amp;messageSender=#messageSender&amp;soapAction=urn:MidwareWebServiceIntf-MidwareWebService#ExecuteCommand"/>
        <to uri="bean:trimResponse"/>
        <to uri="bean:xmlProcessorTrim"/>
        <to uri="bean:validateResponse"/>
    </route>



</camelContext>



<bean id="messageSender" class="org.springframework.ws.transport.http.HttpComponentsMessageSender">
    <property name="httpClient" ref="httpClient"/>
    <property name="readTimeout" value="30000"/>
    <property name="connectionTimeout" value="30000"/>
</bean>


<bean id="requestConfigBuilder" class="org.apache.http.client.config.RequestConfig"
      factory-method="custom">
    <property name="socketTimeout" value="30000" />
    <property name="connectTimeout" value="30000" />
</bean>

<bean id="requestConfig" factory-bean="requestConfigBuilder" factory-method="build" />

<bean id="poolingConnectionManager" class="org.apache.http.impl.conn.PoolingHttpClientConnectionManager">
    <property name="defaultMaxPerRoute" value="20"/>
    <property name="maxTotal" value="20"/>
</bean>

<bean id="httpClientBuilder" class="org.apache.http.impl.client.HttpClientBuilder"
      factory-method="create">
    <property name="defaultRequestConfig" ref="requestConfig" />
    <property name="connectionManager" ref="poolingConnectionManager"/>
</bean>



<bean id="httpClient" factory-bean="httpClientBuilder" factory-method="build" />

但是当我运行该项目时，出现以下异常

这是否与我一起使用的 API 版本不兼容有关？

感谢@smarquis提供了非常有用的答案，我终于可以正确配置Spring-Ws连接管理器了。这是正确的配置。不要忘记使用 interceptedHttpClientBuilder 部分。如果没有它，您会遇到此异常:org.apache.http.ProtocolException:Content-Length header 已存在(有关更多信息，请参阅此thread)
