The XML structure that the restful service log prints;
How do You convert an XML structure to JSON?
I used script and payloadFactory, output the JSON string in the ESB, and the print log in the invoked service is still XML
input:
enter image description here
The message received by the service(http://192.16.110.142:8081/dqcsweb/ES/test):
<jsonObject><Code>10</Code><Price>11</Price></jsonObject>
expectations:
{
"code":"10",
"Price":"11"
}

Answer 1

Can you change the format of the endpoint invoked to rest. Please refer to the follwoing sample configuration.
<send>
<endpoint>
<address format="rest" uri="http://192.16.110.142:8081/dqcsweb/ES/test"/>
</endpoint>
</send>
The used pox format results in the message transformed into plain old XML format. Please refer to the documentation [1] to further clarify this.

Update
Can you enable wire logs by uncommenting the following [2] in log4j.properties file. You need to perform a server restart to enable this. This allows you to see the request sent out of the EI server. Please check if the request going out of the EI contains the necessary payload.
log4j.logger.org.apache.synapse.transport.http.wire=DEBUG
