No adapter for endpoint

问题

I have a Java class with the @Endpoint annotation. It was working fine until I try to add another parameter - MessageContext and I am getting the "No adapter for endpoint"

See my method signature below:

@PayloadRoot(localPart = "PolicyNewBusinessQuoteRequest", namespace = TARGET_NAMESPACE)
  @ResponsePayload
  public PolicyNewBusinessQuoteResponseDocument processQuoteRequest(@RequestPayload PolicyNewBusinessQuoteRequestDocument requestDocument, MessageContext messageContext) throws Exception {
}

回答1:

Your data is not sufficient to answer this question.

But most of the times,

java.lang.IllegalStateException: No adapter for endpoint […]: 
Is your endpoint annotated with @Endpoint, 
or does it implement a supported interface like MessageHandler or PayloadEndpoint?

this exception is can be resolved with

Addition of @XmlRootElement annotation on your request and response class.
