Spring-ws no adapter for endpoint ***: Is your endpoint annotated with @ endpoint?

When using spring ws to develop WebService, the following error occurs:

No adapter for endpoint [Public COM. IBM. eve. schemas. requestchargeresponse COM. IBM. eve. WS. requestchargeendpoint. requestcharge (long)]: Is your endpoint annotated with @ endpoint, or does it implement a supported interface like messagehandler or payloadendpoint?

But I tried it. This is not the problem.

The xsd I wrote is correct,

After searching for half a day, the original request interface was written incorrectly. If the parameter in your request method is an object:

<Xs: element name = "Requestchargerequest">
<Xs: complextype>
<Xs: sequence>
<Xs: Element minoccurs = "0" name = "vin" type = "XS: string"/>
<Xs: Element minoccurs = "0" name = "Soc" type = "XS: Double"/>
<Xs: Element minoccurs = "0" name = "connvoltage" type = "XS: int"/>
<Xs: element name = "timerange" type = "EVE: timerange"/>
<Xs: element name = "geolocation" type = "EVE: geolocation"/>
</Xs: sequence>
</Xs: complextype>
</Xs: Element>

This object must also be used in the method corresponding to your endpoint:

@ Payloadroot (localpart = "requestchargerequest", namespace = "http://ibm.com/eve/schemas ")
@ Namespace (prefix = "Sch", uri = "http://ibm.com/eve/schemas ")
Public requestchargeresponse requestcharge (RequestchargerequestRequest ){

The above error was reported only after I wrote the five parameters.
