我在wso2 esb 4.8.1中有简单的基本代理，我将输入消息发送到我的端点并显示结果。
XML => Endpoint => XML
我的端点只接收带有特定SOAPAction的SOAP（soap envelope，body）消息，因此我设置了
<property name="SOAPAction" value="MY VALUE" scope="transport"/>
发送之前，我知道这是正确的设置。 发送我的消息后，我收到此错误
SOAP-ENV:Client.PayloadSize
The SOAP payload exceeds the configured size limit of the server!
我不知道为什么，因为当我通过restClient发送此消息时，我会收到结果。
为了消除输入错误，我设置了PayloadFactory并设置了消息（我确定这条消息没问题），我得到了同样的错误。
我发送的代码：
<property name="Content-Type"
value="text/xml"
scope="axis2"
type="STRING"/>
<property name="SOAPAction" value="MY VALUE" scope="transport"/>
<send>
<endpoint>
<http method="POST"
uri-template="http:address"/>
</endpoint>
</send>
有什么想法吗？

ESB日志显示此错误：

我在这个网站上看过 http://www.w3schools.com/xml/xml_soap.asp 这是客户端问题，但正如我之前写的那样，当我执行CTR + C和CTR + V此有效负载消息并将其放入restClinet时，我得到了结果。 也许ESB添加一些奇怪的东西并发送它？

我不知道为什么在我的消息之前有“4d4”，之后有“0”。之前和之后都有“[\ r] [\ n]”。这是错的吗？
