I created a small Spring Boot application to gather data from the public API. Now, I created a base skeleton, I want to test RestTemplate json consumption and make a test that will mimic the behaviour of public API.
The question, how to mimic json consumption of RestTemplate in tests?
Precisely, how to mock RestTemplate in tests, so it will accept json from a local file?
My Service below:
#Service
public class RecordsTrackerService {
private RestTemplate restTemplate;
#Autowired
public RecordsTrackerService(RestTemplate restTemplate) {
this.restTemplate = restTemplate;
}
public void updateRecords() {
Object obj = restTemplate.getForObject("sample_url", Object.class);
}
}
I tried searching similar questions but there is nothing I could find so far.
You can use springs MockRestServiceServer to simulate the request/response that you need. You essentially, outline to spring what the expected request is along with the expected response. Full tutorial here:

I have developed a RESTful web service using Spring Boot. Once a URL is entered, a JSON resource is returned. The server side is not perfectly JSON API conformed but it works.
Now I want to secure the RESTful service with simple HTTP basic authentication. Simply put, if a client send a HTTP GET in order to access
http://mycompany.com/restful/xyz
it will receive a HTTP unauthenticated error, unless the request is configured with proper Authorization basic XXXXXXXX. The xxxxxx is the encrypted form of user:pwd
I wanted to do it with Spring Security. After some googling I might need to create some class like:
#Configuration
#EnableGlobalMethodSecurity(prePostEnabled = true)
#EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Autowired
public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
....
}
#Override
protected void configure(HttpSecurity http) throws Exception {
....
}
}
There are two things I need to understand:
Most Spring Security sample I found were somehow related to web application using Spring MVC, but I am sure that it can be used in a scenario as shown above - a standalone web service (in a Tomcat all right, but not a web app);
Can anyone show some code snippet in the two methods above that work to the effect that only certain user/pwd is allowed to pass the filter to the resource,
http://mycompany.com/restful/xyz
otherwise a HTTP authentication error code is returned.
Can anyone help?
You can have something like this:
#Configuration
#EnableGlobalMethodSecurity(prePostEnabled = true)
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/restful/**").hasRole("ROLE_USER").and().httpBasic();
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("john").password("mypass").roles("ROLE_USER");
}
}
I am trying ServiceStack to develop few web services, but I am unable to configure method having null as input.
public class UserService : IService
{
public object Get()
{
//gets all users
//not working
}
public object Get(FindUser request)
{
//this works
}
}
public override void Configure(Container container)
{
Routes
.Add<FindUser>("/user/{id}") //this works
.Add(null, "/user");//how to configure this route
}
There is no concept of a null input, a client must call a specific Service and each Service in ServiceStack needs a request DTO which defines the service entry point and the Request that it receives - that Request DTO can be empty.
First, I'm new to Web Services. I have a didactical task at university about developing web application and web service for something like managing distribuited drug stores.
I've developed a working Web Application using struts2 framework, but now I'd like to extend it to a Web Service. I found that I could implement a class (named for example WSManager) which is a wrapper of the various Web App Controllers.
It would have to make calls to static methods of those Controllers. Web Application is designed to provide a Controller for each use case.
for example a Controller is like this:
public class AdminLocaleController extends AbstractController {
private static final long serialVersionUID = -6266455088438602574L;
private static Logger logger = Logger.getLogger(AdminLocaleController.class);
private List<Prodotto> prodotti;
#Override
public String execute() {
prodotti = initializeAdminLocaleView();
return "success";
}
public List<Prodotto> getProdotti() {
return prodotti;
}
public void setProdotti(List<Prodotto> prodotti) {
this.prodotti = prodotti;
}
public static List<Prodotto> initializeAdminLocaleView() {
logger.info("Recupero lista di prodotti da ordinare");
DBController dbController = new DBControllerImpl();
return dbController.getProdottiDaOrdinare();
}
}
and the WSManager class makes a call to the initializeAdminLocaleView(), just like this:
/* AdminLocaleController */
public List<Prodotto> initializeAdminLocaleView(){
return AdminLocaleController.initializeAdminLocaleView();
}
I would create a Web Service in Eclipse providing that service class.
If I'm doing something wrong I ask you the proper way to extend the web application to a web service.
Otherwise, my matter is if I have to (and how to) manage parameters and attributes between Views (jsp) and Controllers.
Finally I have some Controllers (each of these implement SessionAware) which process data and store returned object in Session (for example a LoginController which saves a User bean in request session). Deeper, my question is how I should manage Web App's session stored attributes in case of a Web Service. If I have method calls in WSManager which passes a User bean as parameters, how could I obtain it from a session. Or simply, do I have necessity of obtaining something from a session from a Web Service perspective?
I'm sure I've written a confusionary question, but confusionary is my state of mind at this point too.
I'm trying to deploy a weeb-service, generated from an EJB into glassfish, but, for some reason, my web service is never visible in Glassfish. The web-service is defined from an EJB interface as follows :
#Remote
#WebService
public interface TemplateEJBRemote {
public abstract #WebResult(name="found") Template find(#WebParam(name="templateId", mode=Mode.IN) Long id);
}
This EJB interface has a Local implementation :
#Local
#Stateless
public class TemplateEJBImpl implements TemplateEJBRemote {
#PersistenceContext(unitName=NamingConstants.PERSISTENCE_CONTEXT)
private EntityManager entityManager;
#Override
public Template find(Long id) {
return entityManager.find(Template.class, id);
}
}
And they're both defined in a war module, which an ear module sends to Glassfish.
Those module produce correctly looking artefacts, including an ear with the correct application.xml :
<application xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_6.xsd"
version="6">
<description>This is the project that will deliver a full usable
EAR including all delivered components. All the project
dependencies here will be included in this</description>
<display-name>my-ear</display-name>
<module>
<web>
<web-uri>my-war-0.0.1-SNAPSHOT.war</web-uri>
<context-root>/my-war</context-root>
</web>
</module>
</application>
When deployed in Glassfish, all infos I can get is
E:\java-ext\glassfish3>bin\asadmin list-components --subcomponents
my-ear-0.0.1-SNAPSHOT <ear, ejb, webservices, web>
my-war-0.0.1-SNAPSHOT.war <WebModule>
Command list-components executed successfully.
it seems to me that, were my web-service really deployed, it would appear below my war submodule, no ?
If not, what can I do to ensure my web-service is correctly defined and deployed ?
[UPDATE 1] In order to give some more informations, i created a smaller web-service endpoint, the infamous Hello world, coded as such :
#WebService
public class Hello {
public String hello(String world) {
return "Salut, "+world+" !";
}
}
using this definition, it is a perfect Glassfiosh web-service :
But, as soon as I make it a bean, as such :
#WebService
#Stateless
public class Hello {
public String hello(String world) {
return "Salut, "+world+" !";
}
}
Things become a little different :
However, as log files told me, HelloService is still present :
[#|2011-03-31T17:55:55.059+0200|INFO|glassfish3.1|javax.enterprise.webservices.org.glassfish.webservices|_ThreadID=339;_ThreadName=Thread-1;|WS00019: EJB Endpoint deployed
autocat-ear-0.0.1-SNAPSHOT listening at address at http://perigee-567125f:8080/HelloService/Hello|#]
I tried to apply the same logic to my initial bean, but with an infortunate result (a 404 error, of course). So I guess there is another issue hidden beneath. But which on ? I can't have any idea.
[UPDATE 2] To make things clear, the EJb I try to deploy is not visible as a web-service in Glassfish console, and its URL can't be pinged by any web client.
I'm looking at my copy of "EJB 3 In Action" and it says:
"A careful look at the code reveals that the #WebService endpoint interface looks similar to the remote interface. You might be tempted to mark the same interface as both a web service and a remote interface, like this:
#WebService
#Remote
public interface PlaceBid {
public Long addBid(String bidderID, Long itemID, Double dibPrice);
}
Unfortunately, although some vendors allow this as an extension, this is not part of the specification, and code that uses this particular attribute combination won't be portable."
You're going to have to remove the #Remote
You need to do some more troubleshooting. Have a look at the logs in glassfish3/glassfish/domains/domain1/logs. Or if you have standalone or cluster nodes look in glassfish3/glassfish/nodes/<nodename>/<instancename>/logs.
Also, log into the admin page "http://localhost:4848", default username is admin, default password is adminadmin. On the left there is a tree, find Applications, then your Ear should be listed there. Click it and you'll see a list of modules and components. If your web service is listed there you can click View Endpoint. There is a built-in tester, and you can get the wsdl URL there too.
update 1:
You don't have any #WebMethod(operationName = "blah) on your hello(). Maybe if there are no WebMethods GlassFish decides it's not worth making your web service available.
update 2: More complete example of how my web service is put together inside the ear. I'm pretty sure you don't have to separate the #WebService and #Stateless classes, but I like it that way because it feels cleaner and seems to separate the concerns.
war:
SomePojo.java:
#WebService(targetNamespace="blah.com")
public class SomePojo {
#EJB
private BlahSessionLocal blahSession;
#WebMethod(operationName = "hello")
public String hello(#WebParam(name = "user_id") Integer userId) throws Exception {
return blahSession.hello(userId);
}
}
ejb jar:
BlahSessionLocal.java
#Local
public interface BlahSessionLocal {
String hello(Integer userId);
}
BlahSessionBean.java
#Stateless(mappedName = "BlahSession")
public class BlahSessionBean implements BlahSessionLocal {
public String hello(Integer userId) {
return "hello user " + userId);
}
}
