Mule连接器:如何在SSL端点上配置HTTP
Mule连接器:如何在SSL端点上配置HTTP
提问于 2014-08-25 17:29:08
我有一个关于Mule Riak连接器及其配置可能性的问题。我想使用HTTPS端点配置连接器。现在，连接器包含一个org.mule.modules.riak.config.RiakHttpClientConfigurationAdapter，而不是HttpConnector。
为了使我的方法更清楚，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，这是失败的：
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，您能想出一种方法来重用现有的HttpConnector (所有的SSL配置设置)吗？实际上，我不想再次配置HttpClient并将其添加到riak客户端。
编辑1:通过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>遗憾的是，对反射部分的调用已经失败。我在Spring中所做的应该相当于这篇Java文章：
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>异常：

}HttpClient库版本相差太大，这样才能使情况成功。在某种程度上也需要修改这些版本。

我能想到办法！
- 用
doClientConnect更改Mule HTTP connector上的可见性。 - 使用Spring通过此方法获取
HttpClient的实例。 - 注射
riakclient - 利润！
