A)
@SlingServletResourceTypes(resourceTypes ="/my/resourcetype", methods = {"get"}) public class MyServlet extends SlingSafeMethodServlet {
@Override
protected void doGET(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
// Handle get request
}
}
B)
@SlingServletResourceTypes(resourceTypes="/my/resourcetype", methods = { "GET" }) public class MyServlet extends SlingAllMethodsServlet {
@Override
protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
// Handle get request
}
}
C)
@SlingServletResourceTypes(resourceTypes ="/my/resourcetype", methods = { "get" }) public class MyServlet extends SlingSafeMethodServlet {
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
