我正在尝试使用以下代码动态设置HTTP出站地址 -
<flow name="dynamic-http-address" doc:name="dynamic-http-address" processingStrategy="synchronous">
<http:inbound-endpoint exchange-pattern="request-response"
host="localhost" port="8081" doc:name="HTTP" />
<logger level="INFO" doc:name="Logger" />
<set-variable variableName="address" value="http://www.google.com/"
doc:name="Variable" />
<http:outbound-endpoint address="#[address]"
method="GET" doc:name="HTTP" />
</flow>
但是，当我启动应用程序时，它无法启动并抛出以下异常 -
PropertyAccessException 1:
org.springframework.beans.MethodInvocationException: Property 'protocol' threw exception; nested exception is java.lang.IllegalArgumentException: Address '#[address]' for protocol 'http' should start with http://

知道为什么Mule希望动态地址以http：//开头？
答案 0 :(得分：3)
因为Mule中的URIBuilder类断言端点地址始终与端点的协议一致。这是有道理的，因为混合协议无论如何都不会起作用。使用address="http://#[address]"。
