Hello,
I need to know the existing endpoints of a JAX-RS interface.
I did the following solution first:
List<ClassResourceInfo> resources =
jaxrsServerFactoryBean.getServiceFactory().getClassResourceInfo();
for (ClassResourceInfo resource : resources) {
if (FooRestService.class.isAssignableFrom(resource.getServiceClass())) {
LOG.warn("Foo REST-Service locally available!");
LOG.warn("Service path: " + resource.getPath().value());
for (OperationResourceInfo ori :
resource.getMethodDispatcher().getOperationResourceInfos()) {
if (ori.getAnnotatedMethod().getName().equals("retrieve")) {
LOG.warn("Method path: " +
ori.getAnnotatedMethod().getAnnotation(Path.class).value());
}
}
}
}
Output:
Foo REST-Service locally available!
Service path: /foo/something
Method path: /{id}
This solution however may not work, when dealing with distributed services. One
server instance may not have all
services registered to its jaxrs:server bean configured in Spring.
What we do have available on all instances are the JAX-RS interfaces because of
we need to perform requests to the other
instances of course.
So, is there an easy way to get all the endpoints or do I have to implement the
reflection on my own?
I do know, that CXF is already handling this in some classes. I tried the
following, which does not work, because the
iteration has no items to iterate through. I would prefer to reuse the existing
code in CXF for this.
JAXRSServiceFactoryBean serviceFactoryBean = new JAXRSServiceFactoryBean();
serviceFactoryBean.setResourceClass(FooRestServiceImpl.class);
Service service = serviceFactoryBean.create();
for (Endpoint endpoint : service.getEndpoints().values()) {
LOG.warn("Endpoints: " + endpoint.getEndpointInfo());
}
Output:
<nothing>
Thank you in advance and best regards,
Marko
