i want use invoke a remote method by use feignclient,but the remote method was execute duplicate ,this is my code(i'm not good at english,so fogive me)
#ViewScoped
#ManagedBean
#Named("cdProductTemplateView")
public class CdProductTemplateView extends BaseView {
public void cdPost() {
//cdProTempContext,just a bean
cdProductClient.cdPost(cdProTempContext);
}
}
client:
#FeignClient(value = "service", path = "/cdproduct")
public interface CdProductClient {
#RequestMapping("/cdPost")
CdProduct cdPost(#RequestBody CdProductTemplateContext
cdProTempContext) throws BusinessException, SystemException;
}
controller:
#RequestMapping("/cdproduct")
#RestController
public class CdProductController{
public CdProduct cdPostProduct(CdProductTemplateContext cdProTempContext, String resPath)
throws BusinessException, SystemException {
return cdProductService.cdPostProduct(cdProTempContext, resPath);
}
#RequestMapping("/cdPost")
public CdProduct cdPost(#RequestBody CdProductTemplateContext cdProTempContext, HttpServletRequest request) {
return cdPostProduct(cdProTempContext, resPath);
}
}
serviceImpl：
#Named("cdProductService")
public class CdProductServiceImpl implements CdProductService {
#Override
public CdProduct cdPostProduct(CdProductTemplateContext
cdProTempContext, String resPath) throws BusinessException, SystemException {
//proPkgRequset: a bean ProductPackageRequest
cdProService.submitProductPackage(proPkgRequset);
//this just invoke method(ICDMarketplaceAPIService.submitProductPackage )
}
}
ICDMarketplaceAPIService
#WebService(targetNamespace = "http://www.***.com", name = "IMarketplaceAPIService")
#XmlSeeAlso({ObjectFactory.class})
public interface ICDMarketplaceAPIService {
#WebMethod(operationName = "SubmitProductPackage")
#Action(input = "http://www.***.com/IMarketplaceAPIService/SubmitProductPackage", output = "http://www.***.com/IMarketplaceAPIService/SubmitProductPackageResponse")
#RequestWrapper(localName = "SubmitProductPackage", targetNamespace = "http://www.***.com", className = "SubmitProductPackage")
#ResponseWrapper(localName = "SubmitProductPackageResponse", targetNamespace = "http://www.***.com", className = "SubmitProductPackageResponse")
#WebResult(name = "SubmitProductPackageResult", targetNamespace = "http://www.***.com")
public ProductIntegrationReportMessage submitProductPackage(
#WebParam(name = "headerMessage", targetNamespace = "http://www.***.com")
HeaderMessage headerMessage,
#WebParam(name = "productPackageRequest", targetNamespace = "http://www.***.com")
ProductPackageRequest productPackageRequest
);
}
when client invoke remote method,the remote method(controller.cdPost,it was execute duplicate ),but if i remove method(ICDMarketplaceAPIService.submitProductPackage, or not use it) or invoke other method (like query),it's ok.What causes the situation to happen, can anyone help me?
Just add the following code in application.yml:
ribbon:
# Max number of retries on the same server (excluding the first try)
MaxAutoRetries: 0
# Max number of next servers to retry (excluding the first server)
MaxAutoRetriesNextServer: 0

Quick background, our company connects to an ERP system (Sage) via web services for some functions. We have both c# (.net) and java code that performs calls to the Web Service (WS). Recently Sage introduced Basic Authentication into their WS.
Please note: This is a JAVA question, but I'll show an example in C# first to explain.
In the c# program, I first would create an object that is for accessing the WS:
var sageService = new CAdxWebServiceXmlCCServiceBasicAuth();
I then set up credential information:
var sageServiceCallContext = SageFactory.Instance.GetCallContext();
sageService.Credentials = new NetworkCredential(SageUser, SagePwd);
sageService.PreAuthenticate = true;
then finally the call to the specific web service method:
sageCustomerSvcResponse = sageService.run(sageServiceCallContext, "YTDPROF", sageCustomerRequestInXml);
When I set up the service object I use a custom class that looks like this:
public class CAdxWebServiceXmlCCServiceBasicAuth : CAdxWebServiceXmlCCService
{
protected override WebRequest GetWebRequest(Uri uri)
{
HttpWebRequest webRequest = (HttpWebRequest)base.GetWebRequest(uri);
NetworkCredential credentials = Credentials as NetworkCredential;
if (credentials != null)
{
string authInfo = "";
if (credentials.Domain != null && credentials.Domain.Length > 0)
{
authInfo = string.Format(#"{0}\{1}:{2}", credentials.Domain, credentials.UserName, credentials.Password);
}
else
{
authInfo = string.Format(#"{0}:{1}", credentials.UserName, credentials.Password);
};
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
webRequest.Headers["Authorization"] = "Basic " + authInfo;
}
return webRequest;
}
}
What happens is that now, when I perform any call to the web service methods, the GetWebRequest from the class is invoked every time. This is how we implemented basis authentication in c#.
How do I do this in Java?
In the java code currently, I create the service object (that which accesses the web services) this way:
WebServiceInvoker service = new WebServiceInvoker(SageWSURL,"");
and the WebServiceInvoker looks like this (truncated for brevity):
public WebServiceInvoker(String url, String dummy) throws ServiceException, IOException {
serviceLocator = new CAdxWebServiceXmlCCServiceLocator();
service = serviceLocator.getCAdxWebServiceXmlCC(url);
cc = new CAdxCallContext();
cc.setCodeLang("ENG");
cc.setCodeUser("USER");
cc.setPassword("PAWWORD");
cc.setPoolAlias("POOL");
cc.setRequestConfig("adxwss.trace.on=on&adxwss.trace.size=16384&adonix.trace.on=on&adonix.trace.level=3&adonix.trace.size=8");
log = new PrintWriter(new BufferedWriter(new FileWriter("C:/Kalio/service/orders/log.txt")));
}
the webservice locator looks like this:
public class CAdxWebServiceXmlCCServiceLocator extends org.apache.axis.client.Service implements com.adonix.www.WSS.CAdxWebServiceXmlCCService {
public CAdxWebServiceXmlCCServiceLocator() {
}
public com.adonix.www.WSS.CAdxWebServiceXmlCC getCAdxWebServiceXmlCC() throws javax.xml.rpc.ServiceException {
java.net.URL endpoint;
System.out.println("using local Sage Web Servivce URL:" + CAdxWebServiceXmlCC_address);
try {
endpoint = new java.net.URL(CAdxWebServiceXmlCC_address);
}
catch (java.net.MalformedURLException e) {
throw new javax.xml.rpc.ServiceException(e);
}
return getCAdxWebServiceXmlCC(endpoint);
}
public com.adonix.www.WSS.CAdxWebServiceXmlCC getCAdxWebServiceXmlCC(java.net.URL portAddress) throws javax.xml.rpc.ServiceException {
try {
com.adonix.www.WSS.CAdxWebServiceXmlCCSoapBindingStub _stub = new com.adonix.www.WSS.CAdxWebServiceXmlCCSoapBindingStub(portAddress, this);
_stub.setPortName(getCAdxWebServiceXmlCCWSDDServiceName());
return _stub;
}
catch (org.apache.axis.AxisFault e) {
return null;
}
}
and the specific method within that class is this:
public String getCustomer(String constructedXML) throws RemoteException {
**CAdxResultXml result = service.run(cc, "XTDPROF", constructedXML);**
CAdxMessage[] messages = result.getMessages();
for (int i = 0; i<messages.length; i++) {
CAdxMessage message = messages[i];
log.println("X3 get customer message: " + message.getMessage());
log.println("X3 get customer message type: " + message.getType());
}
return result.getResultXml();
}
So my questions is, how to I emulate that override that I see in the .net program in Java? It seems like it would be somewhere in either the service locator or invoker, but the program does not use standard http classes, but this adxwss stuff. I tried a straight c# to java conversion and that way didn't help. I have seen examples where basicAuth is implemented, but not against web service calls.
The c# is pretty clear cut, because once I create the service object using the basicAuth override, every web service calls goes through the orderride. How does that happen in Java?
I'll be happy to provide more info if needed and I'll continue to look/experiment, but at the moment I'm treading water.
Adding:
In tracing through the java code I found the specific web service call (run) where an apache "call" object is created. Is this where basicauth can be added?
public com.adonix.www.WSS.CAdxResultXml run(com.adonix.www.WSS.CAdxCallContext callContext, java.lang.String publicName, java.lang.String inputXml) throws java.rmi.RemoteException {
if (super.cachedEndpoint == null) {
throw new org.apache.axis.NoEndPointException();
}
org.apache.axis.client.Call _call = createCall();
_call.setOperation(_operations[0]);
_call.setUseSOAPAction(true);
_call.setSOAPActionURI("");
_call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11_CONSTANTS);
_call.setOperationName(new javax.xml.namespace.QName("http://www.adonix.com/WSS", "run"));
setRequestHeaders(_call);
setAttachments(_call);
try { java.lang.Object _resp = _call.invoke(new java.lang.Object[] {callContext, publicName, inputXml});
if (_resp instanceof java.rmi.RemoteException) {
throw (java.rmi.RemoteException)_resp;
}
else {
extractAttachments(_call);
try {
return (com.adonix.www.WSS.CAdxResultXml) _resp;
} catch (java.lang.Exception _exception) {
return (com.adonix.www.WSS.CAdxResultXml) org.apache.axis.utils.JavaUtils.convert(_resp, com.adonix.www.WSS.CAdxResultXml.class);
}
}
} catch (org.apache.axis.AxisFault axisFaultException) {
throw axisFaultException;
}
}
The solution I came up with is not elegant, but then I'm not a guru in Java, just know enough to be given these tasks.
Our company uses Sage as our ERP system and Sage has a WSDL to define the basic web services it provides.
Sage Web Servicew WSDL
In their latest version of Sage they went with basic authentication, but did not build it into the new WSDL. Since I could not seem to extend the class (CAdxWebServiceXmlCCService), I just copied/pasted a new class called CAdxWebServiceXmlCCServiceBasicAuth. The full code is shown below if anyone ever has need to deal with something like this in a web service.
The key point where BaiscAuth set set up is in the getCAdxWebServiceXmlCC method. I added setPassword and setUserName to the stub that is returned. What this accomplishes is that every time I perform a webservice method call, that stub is now part of the header.

I have a JSP page wherein user has to enter some custom URL. I want to pass that custom url in #WebInitParam in my servlet
#WebServlet(name = "oauthCustomURL", initParams = {
#WebInitParam(name = "clientId", value = "123"),
#WebInitParam(name = "key", value = "***"),
#WebInitParam(name = "environment", value = "customUrl"),
}) //in value I want to pass the value entered by user
#WebInitParam's are used for the configuration of servlets implemented by third-party libraries. Usually, these libraries use methods getInitParameterNames() and getInitParameter() of abstract class GenericServlet (but you should check in library code for it).
For the dynamic setting of the #WebInitParam you can override those methods in your servlet implementation. Below is an example of how to do it.
#WebServlet(urlPatterns = "/abc/*")
public class DynamicInitParamServlet extends SomeCustomLibraryHttpServlet {
private static final String WEB_INIT_PARAM_NAME = "some.param.name";
private Integer webInitParamValue = null;
#Override
public void init(ServletConfig config) throws ServletException {
// calculate init param value dynamically,
// TODO: implement your own code
webInitParamValue = 2 * 3;
// call custom library servlet init after init parameter value is set
super.init(config);
}
#Override
public Enumeration<String> getInitParameterNames() {
if (webInitParamValue != null) {
final Set<String> initParameterNames = new HashSet<>(Collections.list(super.getInitParameterNames()));
initParameterNames.add(WEB_INIT_PARAM_NAME);
return Collections.enumeration(initParameterNames);
} else {
return super.getInitParameterNames();
}
}
#Override
public String getInitParameter(String name) {
if (WEB_INIT_PARAM_NAME.compareTo(name) == 0 && webInitParamValue != null) {
return "" + webInitParamValue;
} else {
return super.getInitParameter(name);
}
}

I am trying to override Ribbon Server List to get a list of host names from consul. I have the consul piece working properly(when testing with hardcode values) to get the hostname and port for a service. The issue I am having is when I try to autowire in IClientConfig. I get an exception that IClientConfig bean could not be found. How do I override the ribbon configurations and autowire IClientConfig in the ribbonServerList method.
I have tried following the instructions here at http://projects.spring.io/spring-cloud/spring-cloud.html#_customizing_the_ribbon_client on how to customize ribbon client configuration. I keep getting the following error:
Description:
Parameter 0 of method ribbonServerList in com.intradiem.enterprise.keycloak.config.ConsulRibbonSSLConfig required a bean of type 'com.netflix.client.config.IClientConfig' that could not be found.
Which is causing spring-boot to fail.
Bellow are the classes that I am trying to use to create
AutoConfiguration Class:
#Configuration
#EnableConfigurationProperties
#ConditionalOnBean(SpringClientFactory.class)
#ConditionalOnProperty(value = "spring.cloud.com.intradiem.service.apirouter.consul.ribbon.enabled", matchIfMissing = true)
#AutoConfigureAfter(RibbonAutoConfiguration.class)
#RibbonClients(defaultConfiguration = ConsulRibbonSSLConfig.class)
//#RibbonClient(name = "question-answer-provider", configuration = ConsulRibbonSSLConfig.class)
public class ConsulRibbonSSLAutoConfig
{
}
Configuration Class:
#Component
public class ConsulRibbonSSLConfig
{
#Autowired
private ConsulClient client;
private String serviceId = "client";
public ConsulRibbonSSLConfig() {
}
public ConsulRibbonSSLConfig(String serviceId) {
this.serviceId = serviceId;
}
#Bean
#ConditionalOnMissingBean
public ServerList<?> ribbonServerList(IClientConfig clientConfig) {
ConsulSSLServerList serverList = new ConsulSSLServerList(client);
serverList.initWithNiwsConfig(clientConfig);
return serverList;
}
}
ServerList Code:
public class ConsulSSLServerList extends AbstractServerList<Server>
{
private final ConsulClient client;
private String serviceId = "client";
public ConsulSSLServerList(ConsulClient client) {
this.client = client;
}
#Override
public void initWithNiwsConfig(IClientConfig clientConfig) {
this.serviceId = clientConfig.getClientName();
}
#Override
public List<Server> getInitialListOfServers() {

return getServers();
}
private List<Server> getServers() {
List<Server> servers = new ArrayList<>();
Response<QueryExecution> results = client.executePreparedQuery(serviceId, QueryParams.DEFAULT);
List<QueryNode> nodes = results.getValue().getNodes();
for (QueryNode queryNode : nodes) {
QueryNode.Node node = queryNode.getNode();

I am trying to make a client connect to a web service and use a SetFlight method on the server.
The environment is Intellij Ultimate, Java 7, and JAXWS. The generation of the classes from the WSDL has been done.
Among the generated classes I have two services:
#WebServiceClient(name = "FOService", targetNamespace = "http://temporaryuri.org.au/", wsdlLocation = "http://fovanil.com/FOService.svc?wsdl")
public class FOService
extends Service
{
private final static URL FOSERVICE_WSDL_LOCATION;
private final static WebServiceException FOSERVICE_EXCEPTION;
private final static QName FOSERVICE_QNAME = new QName("http://temporaryuri.org.au/", "FOService");
static {
...
And the IFO service
#WebService(name = "IFOService", targetNamespace = "urn:fo.com.au/schema/common")
#SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
#XmlSeeAlso({
ObjectFactory.class
})
public interface IFOService {
/**
*
* #param parameters
* #return
* returns svc.SetFlightResponse
*/
#WebMethod(operationName = "SetFlight", action = "http://fo.com.au/SetFlight")
#WebResult(name = "SetFlightResponse", targetNamespace = "urn:fo.com.au/schema/common/types", partName = "parameters")
public SetFlightResponse SetFlight(
#WebParam(name = "SetFlightRequest", targetNamespace = "urn:fo.com.au/schema/common/types", partName = "parameters")
SetFlightRequest parameters);
}
I have looked at some examples of implementing a client https://docs.oracle.com/javaee/5/tutorial/doc/bnayn.html however this differs.
I would have thought using this would be:
IFOSerice service = new IFOService();
service.SetFlight(someinstanceofflight); //setFlight is not a available method
How do I make a client and use the SetFlight method?
This code worked:
SetFORequest request = new SetFORequest();
SetFOResponse response = new SetFOResponse();
request.setFO(flight);
FOService foService = new FOService();
IfoService ifoService = foService.getWSHttpBindingIFOService();
ifoService.setFO(request);
this is my annotations:
#RequestMapping(method = RequestMethod.POST, value = "/trade/createrequisition")
now i would like to get request method it is POST in this case and the value it is /trade/createrequisition in this case.
How to do this using reflection in java.
Please help me to resolve this.
EDIT:
this is what is my actual method :
#PreAuthorize("isAuthenticated() and hasPermission(#request, 'CREATE_REQUISITION')")
#RequestMapping(method = RequestMethod.POST, value = "/trade/createrequisition")
public #ResponseBody
void createRequisition(#RequestBody CreateRequisitionRO[] request,
#RequestHeader("validateOnly") boolean validateOnly) {
....
}
this is how i tried to get the #RequestiMapping:
package com.hexgen.reflection;
import java.lang.reflect.Method;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.hexgen.api.facade.HexgenWebAPI;
public class WebAPITest {
public static void main(String[] args) {
try {
Class<HexgenWebAPI> clazz = HexgenWebAPI.class;
Method methodAnnotaion = clazz.getMethod("createRequisition");
RequestMapping methodRequestMappingAnnotation = methodAnnotaion.getAnnotation(RequestMapping.class);
RequestMethod[] methods = methodRequestMappingAnnotation.method();
String[] mappingValues = methodRequestMappingAnnotation.value();
for(RequestMethod req : methods){
System.out.println("RequestMethod : " + req);
}
for (String string : mappingValues) {
System.out.println("mappingValues : " + string);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
but i get this exception :
java.lang.NoSuchMethodException: com.hexgen.api.facade.HexgenWebAPI.createRequisition()
at java.lang.Class.getMethod(Class.java:1605)
at com.hexgen.reflection.WebAPITest.main(WebAPITest.java:12)
As you are trying to get the RequestMapping annotation, and it can be placed at a class or a method, see both uses below:
For a class YourClass:
Class<YourClass> clazz = YourClass.class;
RequestMapping clazzRequestMappingAnnotation = clazz.getAnnotation(RequestMapping.class);
RequestMethod[] methods = clazzRequestMappingAnnotation.method();
String[] mappingValues = clazzRequestMappingAnnotation.value();
For a method methodName at a class YourClass:
Class<YourClass> clazz = YourClass.class;
Method method = clazz.getMethod("methodName");
RequestMapping methodRequestMappingAnnotation = method.getAnnotation(RequestMapping.class);
RequestMethod[] methods = methodRequestMappingAnnotation.method();
String[] mappingValues = methodRequestMappingAnnotation.value();
If this annotation is on a class (eg: Test) then
RequestMapping a = Test.class.getAnnotation(RequestMapping.class);
RequestMethod m = a.getMethod();
