I want to implement my own SOAP webservcie using spring-ws. I have written a xsd, from which a Java class is generated.
This is my webservice configuration:
@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {
@Bean
public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
MessageDispatcherServlet servlet = new MessageDispatcherServlet();
servlet.setApplicationContext(applicationContext);
servlet.setTransformWsdlLocations(true);
return new ServletRegistrationBean(servlet, "/ws/*");
}
@Bean(name = "foo")
public DefaultWsdl11Definition defaultWsdl11DefinitionFoo(){
DefaultWsdl11Definition defaultWsdl11Definition = new DefaultWsdl11Definition();
defaultWsdl11Definition.setPortTypeName("FooPort");
defaultWsdl11Definition.setLocationUri("/ws");
defaultWsdl11Definition.setTargetNamespace("foo");
defaultWsdl11Definition.setSchema(fooSchema());
return defaultWsdl11Definition;
}
@Bean
public XsdSchema fooSchema() {
return new SimpleXsdSchema(new ClassPathResource("foo.xsd"));
}
This is my xsd:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="foo" elementFormDefault="qualified">
<xs:complexType name="Foobject">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="population" type="xs:int"/>
</xs:sequence>
</xs:complexType>
This is my endpoint:
@Endpoint
public class Fooendpoint {
private static final String NAMESPACE_URI = "foo";
@PayloadRoot(namespace = NAMESPACE_URI, localPart = "bar")
@ResponsePayload
public Foobject getCountry(@RequestPayload Foobject request) {
return new Foobject("string", 0);
}}
And finally this is the autogenerated WSDL the webservice publishes at http://localhost:8080/ws/foo.wsdl
<wsdl:definitions targetNamespace="foo" xmlns:sch="foo" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="foo" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
<wsdl:types>
<xs:schema elementFormDefault="qualified" targetNamespace="foo" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="Foobject">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="population" type="xs:int"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
</wsdl:types>
<wsdl:portType name="FooPort"/>
<wsdl:binding name="FooPortSoap11" type="tns:FooPort">
<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
</wsdl:binding>
<wsdl:service name="FooPortService">
<wsdl:port binding="tns:FooPortSoap11" name="FooPortSoap11">
<soap:address location="http://localhost:8080/ws"/>
</wsdl:port>
</wsdl:service>
in the WSDL there is no messages and operations. What am I missing?
Update: I modified the XSD:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="foo" elementFormDefault="qualified" xmlns:tns="foo">
<xs:element name="fooRequest">
<xs:complexType>
<xs:sequence>
<xs:element name="foo" type="tns:Foobject"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="fooResponse">
<xs:complexType>
<xs:sequence>
<xs:element name="string" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="Foobject">
<xs:sequence>
<xs:element name="string" type="xs:string"/>
<xs:element name="int" type="xs:int"/>
</xs:sequence>
</xs:complexType>
The WSDL now has messages and bindings:
<wsdl:definitions targetNamespace="foo" xmlns:sch="foo" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="foo" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
<wsdl:types>
<xs:schema elementFormDefault="qualified" targetNamespace="foo" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="fooRequest">
<xs:complexType>
<xs:sequence>
<xs:element name="foo" type="tns:Foobject"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="fooResponse">
<xs:complexType>
<xs:sequence>
<xs:element name="string" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="Foobject">
<xs:sequence>
<xs:element name="string" type="xs:string"/>
<xs:element name="int" type="xs:int"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
</wsdl:types>
<wsdl:message name="fooResponse">
<wsdl:part element="tns:fooResponse" name="fooResponse"/>
</wsdl:message>
<wsdl:message name="fooRequest">
<wsdl:part element="tns:fooRequest" name="fooRequest"/>
</wsdl:message>
<wsdl:portType name="FooPort">
<wsdl:operation name="foo">
<wsdl:input message="tns:fooRequest" name="fooRequest"/>
<wsdl:output message="tns:fooResponse" name="fooResponse"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="FooPortSoap11" type="tns:FooPort">
<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="foo">
<soap:operation soapAction=""/>
<wsdl:input name="fooRequest">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="fooResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="FooPortService">
<wsdl:port binding="tns:FooPortSoap11" name="FooPortSoap11">
<soap:address location="http://localhost:8080/ws"/>
</wsdl:port>
</wsdl:service>
But when I send a request via SoapUI, the Endpoint is not found:
No endpoint mapping found for [SaajSoapMessage {foo}fooRequest]
For anybody may in need of a "solution" here is a little (real) hack around the problem. The problem is inside the parameter match algorithm in spring. It checks with "parameter instanceof org.w3c.Element". If not you do not have a match and the method is not called.
Btw: If anybody has a better solution please let me know. It must be somewhere.
So in case, you got a:
// No adapter for endpoint [public <CorrectType> <CorrectMethod>(<CorrectArgumentType>)]: Is your endpoint annotated with @Endpoint, or does it implement a supported interface like MessageHandler or PayloadEndpoint?
You may change the method to:
public org.w3c.Element correctMethod(org.w3c.Element parameter) {...
Now the method gets called and you can unmarshal the parameter and marshal the result with a JAXBContext.
For marshaling you can use a method like this:
private <T> T unmarshalParameter(Element element, Class<? extends T> targetClass) {
JAXBContext context = null;
try {
context = JAXBContext.newInstance(targetClass);
return context.createUnmarshaller().unmarshal(element, targetClass).getValue();
} catch (JAXBException e) {
throw new RuntimeException(e);
}
}
Marshaling of the result can be done like:
private <T> Element marshal(T response, String elementName) {
JAXBContext jaxbContext = null;
try {
Document document =
DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
jaxbContext = JAXBContext.newInstance(response.getClass());
DOMResult res = new DOMResult(document);
JAXBElement<?> jaxbElement =
new JAXBElement<>( new QName(NAMESPACE_URI,elementName),
(Class<T>)response.getClass(),
response);
jaxbContext.createMarshaller().marshal(jaxbElement,res);
Element e = (Element)document.getDocumentElement();
return e;
} catch (JAXBException | ParserConfigurationException e) {
throw new RuntimeException(e);
}
}
