I want to redirect request in spring webflux. However, i want to pass the post payload body, and request attributes as well..
I see examples here which speak about redirection but without payload or attributes: Redirection inside reactive Spring Webflux REST controller

The REST URL mapping for Spring Boot when using JHipster is properly according to best REST practices, for example, the following url scheme is employed for GET, PUT, POST & DELETE methods:
api/appointments/{0}
But in the Account resource that comes with every project that uses JHipster generator, the URL scheme is as follows:
api/register
api/activate
api/authenticate
api/account
api/account/change_password
I will like to understand the reason behind this mapping, because it could have been just one URL, like
api/account
and we could provide query parameters in POST and/or PUT methods. But there must be a best practice behind it, though I am not able to completely understand it. Any elaboration on the topic will be great.
I am using Java with Apache CXF to write the backend for AngularJS (single-page web site). In my REST service, I need access to the header of the http request (i.e. parameters and cookies) and I need access to the response header also (i.e. parameters and cookies). The main reason for this is security, authentication purposes and session management. Those are important reasons.
Is there a way of getting both of these structures in Apach CXF RESTfull code?
You can inject request by using #Context [javax.ws.rs.core.Context]
public Response myRest(#Context HttpServletRequest request /*, other parameters if you have like #QueryParam */ ){
request.getCookies();
request.getUserPrincipal();
}
You can set cookie or header in response as bellow
ResponseBuilder builder = Response.ok(); //Response.status(500) either way
builder.cookie(arg0);
builder.header(arg0, arg1);
return bulider.build();
Is there a way in CXF to implement a Restful webservice which will accept different xml requests using one Web service method?
e.g. Can one create a Restful endpoint to accept this type of XML through one web service method?
<Data>
<Book>BN1</Book>
</Data>
& this too using same web service method?
<Data>
<Disk>DN1</Disk>
</Data>
I think this post: Apache CXF: Consume XML POST payload... shows a good example of how to declare a CXF REST service as receiving POST XML data.
For your example of handling different XML content, instead of 'Bean' in the above you'd have an #XmlRootElement that's the Data, with a child that's a #XmlAnyElement.
Ok so I am using this for generic XML.
public interface Callback {
#POST
#Path("/submit")
#Consumes("text/xml")
#Produces("application/xml")
public Response submit(String incomingXML);
}
Basically I am getting whole xml as a string in my method body, As CXF is not parsing it, it can remain generic.
I am trying to consume a restful Web service using camel.
For that I am configuring dynamic endpoint url as the RESTful url is created at the runtime. Everytime I am checking if the particular endpoint url is registered as a route in my camel context using following method of CamelContext class.
Endpoint hasEndpoint(String uri);
In this case, if the endpoint is not registered then I add a route to my camel context using a custom Route Builder.
I am using camel HTTP component for this. This is working fine for me as of now.
However, I believe performance wise this is not good as everytime I have to check if a route is registered with the camel context and if not then register the same before making the webservice call.
Can some body please tell me if there is a better way to consume RESTful Web services in camel?
I also want to know if the RESTful webservice I am consuming uses OAuth 2.0 protocol, do I need to change anything in my code as I am just consuming it?

Thanks for your reply.
I am checking if the route is already exists to make sure I don't end up adding duplicate route(s) to the camel context.
Regarding long lived routes and route dynamics, can u please explain a bit regarding this? How do I implement route dynamics?
It would also be helpful if you could point me to some CXF-RS producer example.. I read the documentation of CXFRS but could not understand it clearly.
Thanks
Nilotpal
Exactly why do you need to check if the route is registred or not before making the call? You should perhaps setup a more long lived route and route dynamic towards resfull resources.
As for Rest with camel, I think the HTTP component does a great job, but there are higher level components to use as well, more designed for REST.
CXFRS and Restlet, producer examples for restlet can be found in the Apache Camel source unit tests, such as this RestletProducerGetTest.java.
As for oAuth 2.0, Camel has some oAuth support built-in, especially for google. Look for the gauth component. There is even a tutorial, however it might not be aligned with your case, it still might give some background so you could solve your issues: http://camel.apache.org/tutorial-oauth.html
CamelContext context = new DefaultCamelContext();
My Aim
I am trying to intercept the incoming request and based on the ip of the incoming request i want to invoke dynamic endpoint of get offers
context.addRoutes(new RouteBuilder(){
public void configure(){
from("jetty:localhost:9000/offers")
.process(new Processor(){
public void process(Exchange exchange) throws Exception {
//getting the request object
HttpServletRequest req = exchange.getIn().getBody(HttpServletRequest.class);
//Extracting information from the request
String requestIP=req.getRemoteAddr();
/**
* After getting the ip address i do necessay processing
* and then add a property to exchange object.
* Destination ip address is the address to which i want to
* send my request
*/
exchange.setProperty("operatorAddress",destinationIpAddress);
}
})
.to("direct:getOffers")
.end();
}
});
Now i will invoke the getOffers endpoint
so first i will register it
context.addRoutes(new RouteBuilder(){
public void configure(){
from("direct:getOffers")
.toD("jetty:${property.operatorAddress}/api/v2.0/offers?
bridgeEndpoint=true")
.end();
}
});
so we can access the operatorAddress property of exchange object as
${property.operatorAddress}
also when we have dynamic routes then we need to call
.toD() and not .to()
I want to write a RESTful web service for client to upload data.
The data format is JSON
But I don't know much about it,can you give some sample code in JAVA? include the code of service and client that could demonstrate me the whole process of data uploading.
A good place to start is the Jackson Tutorials. Then look at either Jersey's JSON Support or RESTeasy's JSON Support depending on which framework you happen to be using. Data uploading is a open-ended topic since there are a number of different ways that it can be accomplished. If you POST JSON directly to the service then you can use JAXRS annotations like:
#Path("/myservice")
public class MyService {
#POST #Consumes("application/mytype+json")
public Response processPostRequest (JsonBeanType postData) {
...
}
}
The processPostRequest method will be invoked whenever a client POSTs data that includes the Content-Type: application/mytype+json HTTP header to the /myservice resource.
Another way to upload data is to send it using an HTML form. There are a bunch of examples of processing HTML forms in Java. The SO question How can I handle multipart form data post requests in my Java servlet should start you off in the right direction.
