I'm configuring my resteasy app and need to turn of auto scanning (two jaxrs applications are in the classpath and it breaks at loading)
For that reason I have configured my web.xml as follow:
<context-param>
<param-name>resteasy.scan</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<param-name>resteasy.resources</param-name>
<param-value>
io.swagger.jaxrs.listing.ApiListingResource,
com.mycompany.resource.ClientResource,
com.mycompany.resource.AccountResource,
... etc
</param-value>
</context-param>
Is there any way in resteasy to scan by package (com.mycompany.resource.*
) name instead of having to add each resource ? It seems it's possible with jaxrs but not resteasy
The documentation is quite clear:
A comma delimited list of fully qualified JAX-RS resource class names you want to register
You could implement this on your own using for instance the reflections library. Assuming following textfile:
com.foo.bar.TestResource
com.foo.baz.*
We can read this textfile in the Application class, search for all classes and add it to the Set returned by getClasses
:
@ApplicationPath("/")
public class RestApplication extends Application {
Set<Class<?>> classes;
public RestApplication(@Context ServletContext servletContext) {
classes = new HashSet<>();
try {
URI resourcesConfig = servletContext.getResource("/WEB-INF/resources.txt").toURI();
List<String> resources = Files.readAllLines(Paths.get(resourcesConfig), Charset.forName("UTF-8"));
for (String resource : resources) {
parseResources(resource);
}
} catch (IOException | URISyntaxException | ClassNotFoundException ex) {
throw new IllegalArgumentException("Could not add resource classes", ex);
}
}
private void parseResources(String resource) throws ClassNotFoundException, IOException {
if (!resource.endsWith(".*")) {
classes.add(Class.forName(resource));
return;
}
String pkg = resource.substring(0, resource.length() - 2);
Reflections reflections = new Reflections(pkg);
for (Class<?> scannedResource : reflections.getTypesAnnotatedWith(Path.class)) {
classes.add(scannedResource);
}
}
@Override
public Set<Class<?>> getClasses() {
return classes;
}
}
NOTE: We're only adding resources with a @Path
annotation on the class level.
