-----------------------------------
Hey [~4535992],
So there are certainly issues with the way Swagger UI is currently integrated
and Apache Camel. You can make it work, but the approach is fragile to changes.
Essentially, the problem is with that responses returned by SwaggerUiResource
are not **reusable** (but Camel applies a number of processors to it). I don't
know the best way to deal with that (may be you could exclude certain routes or
URLs), but one way to make your example work is:
# Disable *trace="false"*
{code:java}
<camelContext id="camelContext_TestService"
trace="false" xmlns="http://camel.apache.org/schema/blueprint";>
{code}
# Disable streamCache=false
{code:java}
<route handleFault="true"
id="_routeTestServiceEndpointRouteID" streamCache="false">
{code}
# Add *?performInvocation=true&bindingStyle=SimpleConsumer* to
*_from1ServerTestServiceEndpointSSL*
{code:java}
<from id="_from1ServerTestServiceEndpointSSL"
uri="cxfrs:bean:rsServerTestServiceEndpointSSL?performInvocation=true&bindingStyle=SimpleConsumer"/>{code}
# Remove all *<log id="...">***
{code:java}
<!-- <log id="_log1ServerTestServiceEndpointSSL"
message="Processing CXF route....operation name ${headers.operationName}"/> -->
<!-- <log id="_log2ServerTestServiceEndpointSSL"
message="Processing CXF route....http method ${headers.CamelHttpMethod}"/> -->
<!-- <log id="_log3ServerTestServiceEndpointSSL"
message="Processing CXF route....path is ${headers.CamelHttpPath}"/> -->
<!-- <log id="_log4ServerTestServiceEndpointSSL"
message="Processing CXF route....body is ${body}"/> -->{code}
# Remove *<marshal id="_marshal1ServerTestServiceEndpointSSL">*
{code:java}
<!-- <marshal id="_marshal1ServerTestServiceEndpointSSL"> -->
<!-- <json library="Jackson"/> -->
<!-- </marshal> -->{code}
I feel like getting Swagger UI working with Camel and CXF requires too much
tuning right now.
