我对Mule Riak连接器及其配置可能性有疑问。 我想使用HTTPS端点配置连接器。现在连接器包含org.mule.modules.riak.config.RiakHttpClientConfigurationAdapter而不是Mule HttpConnector。
为了使我的方法更清晰，我尝试了以下配置：
<http:connector name="HTTP_HTTPS" cookieSpec="netscape"
validateConnections="true" sendBufferSize="0" receiveBufferSize="0"
receiveBacklog="0" clientSoTimeout="10000" serverSoTimeout="10000"
socketSoLinger="0" doc:name="HTTP-HTTPS" />
<spring:beans>
<spring:bean id="riakclient"
class="org.mule.modules.riak.config.RiakHttpClientConfigurationAdapter">
<spring:property name="httpClient" ref="HTTP_HTTPS"></spring:property>
</spring:bean>
</spring:beans>
当然失败了：
Cannot convert value of type [org.mule.transport.http.HttpConnector] to required type
[org.apache.http.client.HttpClient] for property 'httpClient': no matching editors or conversion
strategy found
现在，您能想到一种实际重用现有HttpConnector（使用所有SSL配置设置）的方法吗？我实际上并不想再次配置HttpClient并将其添加到riak客户端。
编辑1：使用David的方法更新 我直接添加了以下配置以完成反射部分：
<spring:beans>
<!-- get class instance of HttpsConnector for reflection -->
<spring:bean id="httpsConnectorClass"
class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<spring:property name="targetObject" ref="HTTP_HTTPS">
</spring:property>
<spring:property name="targetMethod">
<spring:value>getClass</spring:value>
</spring:property>
</spring:bean>
<!-- get method via reflection of HttpsConnector for reflection -->
<spring:bean id="httpsConnectorMethod"
class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<spring:property name="targetObject" ref="httpsConnectorClass">
</spring:property>
<spring:property name="targetMethod">
<spring:value>getMethod</spring:value>
</spring:property>
<spring:property name="arguments">
<spring:list>
<spring:value>doClientConnect</spring:value>
<spring:value type="java.lang.Class"></spring:value>
</spring:list>
</spring:property>
</spring:bean>
<!-- set method accessible -->
<spring:bean id="httpsConnectorMethodAccessible"
class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<spring:property name="targetObject" ref="httpsConnectorMethod">
</spring:property>
<spring:property name="targetMethod">
<spring:value>setAccessible</spring:value>
</spring:property>
<spring:property name="arguments">
<spring:list>
<spring:value>true</spring:value>
</spring:list>
</spring:property>
</spring:bean>
<!-- call accessible doClientConnect() to retrieve HttpClient -->
<spring:bean id="httpClientFromConnector"
class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<spring:property name="targetObject" ref="HTTP_HTTPS">
</spring:property>
<spring:property name="targetMethod">
<spring:value>doClientConnect</spring:value>
</spring:property>
</spring:bean>
<spring:bean id="riakclient"
class="org.mule.modules.riak.config.RiakHttpClientConfigurationAdapter">
<spring:property name="httpClient" ref="httpClientFromConnector"></spring:property>
</spring:bean>
</spring:beans>
可悲的是，调用已经在反射部分失败了。 我在Spring中所做的应该等同于这个Java部分：
HttpsConnector https = new org.mule.transport.http.HttpsConnector(null);
https.getClass().getMethod("doCientConnect", null).setAccessible(true);
在启动Mule时，我在这个bean的反射部分得到以下异常：
<spring:bean id="httpsConnectorMethod"
class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<spring:property name="targetObject" ref="httpsConnectorClass">
</spring:property>
<spring:property name="targetMethod">
<spring:value>getMethod</spring:value>
</spring:property>
<spring:property name="arguments">
<spring:list>
<spring:value>doClientConnect</spring:value>
<spring:value type="java.lang.Class"></spring:value>
</spring:list>
</spring:property>
</spring:bean>
例外：

HttpClient库版本差异太大，以使案例成功。 还需要以某种方式调整这些版本。
java.lang.ClassCastException: org.apache.commons.httpclient.HttpClient cannot be cast to org.apache.http.client.HttpClient
答案 0 :(得分：2)
我能想到办法！
doClientConnect更改Mule HTTP
connector上setAccessible的展示次数。HttpClient的实例。riakclient
