Why doesn't my Spring-based web application respond to its defined endpoints - spring

I'm developing a simple Spring-based web service userSetting to run on Liberty 8.5.5.9. I'm able to build and deploy the service, and when I start it, it appears to understand its context root (userSetting) but none of its endpoints; I believe I'm missing some essential Spring-based linkage of the parts of the application, but can't figure out which.
The main class of the application looks like:
#SpringBootApplication
#ImportResource("classpath:spring-resource1.xml")
#Import({RESTInterface.class})
public class UserSettingApplication {
private static final LoggerUtils logger = new LoggerUtils( UserSettingApplication.class );
public static void main(String[] args) {
logger.debug( "Entering UserSettingApplication.main()" );
System.out.println( "Entering UserSettingApplication.main()" );
SpringApplication.run(UserSettingApplication.class, args);
logger.debug( "Exiting UserSettingApplication.main()" );
System.out.println( "Exiting UserSettingApplication.main()" );
}
// Dan Vega says: Remember that this going to execute after the
// application context is loaded so you could use it to check if
// certain beans exist or what values of certain properties are.
#Bean
public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
return args -> {
logger.info("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
logger.info(beanName);
}
};
}
}
and the class that defines the endpoints (abbreviated to a single end point) is:
#CrossOrigin
#RestController
#RequestMapping(path = "userSetting")
public class RESTInterface {
...
#RequestMapping(path = "/hello", method = { RequestMethod.GET }, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
public String hello() {
return "Hello, dude!";
}
}
when I try to hit the endpoint http://localhost:9080/userSetting/userSetting/hello, I get the message:
Error 404: java.io.FileNotFoundException: SRVE0190E: File not found: /userSetting/hello
It appears that the RestController has not gotten properly hooked up to the application; in desperation, I tried adding the following line to the main class:
#Import({RESTInterface.class})
but this didn't change anything. Can someone please tell me how to properly connect in the endpoints?

Try hitting http://localhost:9080/userSetting/hello
You are giving 'userSetting' twice in the url

How can I get an application context inside a method of a Spring RestController annotated class

I have a simple app using the #SpringBootAnnotation with a single call on the main method:
SpringApplication.run(App.class, args);
On App.java I am also defining a couple of #BeanS, which give the instance of drivers to access external services:
#Bean
public APEWebservice ape() {
return new APEWebservice(apeWebAddress + ":" + apePort);
}
Then, on the method of one of my #RestControllerS I want to make an access to these beans, so that I can make further calls to these other services, something along these lines:
#PostMapping(path="/talk", consumes = "application/json")
#ResponseStatus(HttpStatus.ACCEPTED)
public Talk talk(#RequestBody InputTalk body) throws ConfigurationException {
ApplicationContext context = new AnnotationConfigApplicationContext(App.class);
APEWebservice ape = context.getBean("ape", APEWebservice.class);
String DRSString = ape.getSoloOutput(input, OutputType.DRSXML);
((ConfigurableApplicationContext)context).close();
try {
Commanded transformed = Preprocessor.transform(body.getContent(), DRSString);
return new Talk(counter.incrementAndGet(), transformed.execute());
}
catch (WrongCommandException e) {
return new Talk(counter.incrementAndGet(), e.getError());
}
}
This looks very ugly, and I am certain I am completely missing the point of Spring and dependency injection. Is there a way to access the context without having to initialize it for every call to the API?
I am using SpringBoot 2.2.1
What about injecting?
#Autowired
private final APEWebservice service;
//code
#PostMapping(path="/talk", consumes = "application/json")
#ResponseStatus(HttpStatus.ACCEPTED)
public Talk talk(#RequestBody InputTalk body) throws ConfigurationException {
String DRSString = service.getSoloOutput(input, OutputType.DRSXML);

404 on Properly mapped SpringBoot RestController

I'm experiencing a little issue that is wasting a lot of my time...
I've created, for demonstration purposes, a simple SpringBoot application using the Eclipse New > Spring Starter Project.
Here is my Application class:
package it.asirchia;
//All needed imports
#SpringBootApplication
public class Application {
public static HashMap<Long,Book> books = new HashMap<Long, Book>();
public static HashMap<Long,Editor> editors = new HashMap<Long, Editor>();
public static HashMap<Long,Person> authors = new HashMap<Long, Person>();
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Then I've created the EditorsApis Controller:
package it.asirchia.apis;
//All needed imports
#RestController
#RequestMapping(value="/editors")
public class EditorsApis {
private static long counter = 0;
#RequestMapping(value="/", method=RequestMethod.GET)
public HashMap<Long, Editor> getAllEditor(){
return Application.editors;
}
#RequestMapping(value="/", method=RequestMethod.POST)
public void postNewEditor(#RequestBody Editor editor){
Application.editors.put(counter++, editor);
}
#RequestMapping(value="/{editorid}", method=RequestMethod.PUT)
public void updateEditor(#PathVariable long editorid,
#RequestBody Editor editor){
Application.editors.put(editorid, editor);
}
#RequestMapping(value="/{editorid}", method=RequestMethod.GET)
public Editor getEditor(#PathVariable long editorid){
return Application.editors.get(editorid);
}
#RequestMapping(value="/{editorid}", method=RequestMethod.DELETE)
public void deleteEditor(#PathVariable long editorid){
Application.editors.remove(editorid);
}
}
And an AuthorsApis and a BooksApis controllers that are very similar to the EditorApis one.
Of course I've created too all the three Pojos:
Editor.class, Person.class and Book.class
I've started up the Eclipse embedded Spring runtime and I can see that all the paths are properly mapped:
INFO [main] s.w.s.m.m.a.RequestMappingHandlerMapping Mapped "
{[/authors/],methods=[GET]}" onto public java.util.HashMap it.asirchia.apis.AuthorsApis.getAllAuthors()
And so on and so forth for all the other Rest APIs I've implemented.
The last three lines of the log are:
Starting beans in phase 0
Tomcat started on port(s): 8080 (http)
Started Application in 5.547 seconds (JVM running for 6.169)
Ok, for me wverything is properly configured, up and running. But when I try to invoke
GET /authors HTTP/1.1
Host: localhost:8080
I obtain:
{
"timestamp": 1507286437765,
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/authors"
}
And the same happens for ALL the REST APIs I've implemented.
Any idea about the reason of this problem?
Thank you.
The following mapping will work localhost:8080/authors/ for you.Since in your method mapping GET you have added the "/" so you should provide the trailing slash in URL also. If you want mapping like this localhost:8080/authors then follow the below code,
#RequestMapping(value={"","/"}, method=RequestMethod.GET)
public HashMap<Long, Editor> getAllEditor(){
return Application.editors;
}
The above will accept,
1) localhost:8080/editors
2) localhost:8080/editors/
Hope this will help.
Can you just try to add a action content in value.Here only specifying only a "/".Like
#RequestMapping(value="/updateEditor", method=RequestMethod.GET)
If you need to add any path variable,you can modify the same with following,
#RequestMapping(value="/updateEditor/{editorid}", method=RequestMethod.PUT)
Just try this method also.

How to use JunitTest with Camel, ActiveMQ and external API

I'm trying to set up JunitTest using camel, activeMq and an Alfresco API
The route I want to test is :
from(Constantes.Direct.DIRECT_GET_AUTHENTIFICATION_TICKET)
.setBody().simple("{"
+ "\"userId\": \"userId\","
+"\"password\": \"password\""
+"}")
.setHeader(Exchange.HTTP_METHOD,constant(Constantes.Headers.HTTP_POST))
.setHeader(Exchange.HTTP_URI,simple(Constantes.Urls.OBTENIR_TICKET))
.to(Constantes.Urls.DUMMYHOST).convertBodyTo(String.class)
.unmarshal().json(JsonLibrary.Jackson, TicketAlfresco.class).process(new Dumper())
.process(new TokenBase64Proc())
.setHeader(Constantes.Headers.SENDER, constant(Constantes.Headers.ALFRESCO))
.setHeader(Constantes.Headers.API_ACTION, constant(SET_ALFRESCO_TOKEN))
.setHeader(Constantes.Headers.HEADER_AUTHORIZATION, simple("${body}"))
.inOut(Constantes.ActiveMq.ACTIVEMQ_IN)
.end();
The first "to" send a request to the Alfresco API and give back a new token.
The last inOut send the token to an activeMQ.
The problem is that when I want to test my route, when the test arrive to inOut inside the activeMq, the test fail because it didn't get any answer.
Do I need to install and embeded broker activeMQ or do I need to Mock the ActiveMQ ? And how can I do that?
For the moment to make it run I use :
mockEndpointsAndSkip("activemq:IN")
But I'm not sure that is the good solution.
Here is the test I have for the moment:
#RunWith(SpringRunner.class)
#EnableAutoConfiguration
#ComponentScan(basePackages = {"fr.gif.wsp.web.service.alfresco*"})
public class RouteGetAuthentificationTicketTest extends CamelTestSupport{
#Autowired private RouteGetAuthentificationTicket routeGetAuthentificationTicket;
//Route to test
private final static String FOURNISSEUR_GET_AUTHENTIFICATION_TICKET = Constantes.Direct.DIRECT_GET_AUTHENTIFICATION_TICKET;
private final static String MOCK_FOURNISSEUR_GET_AUTHENTIFICATION_TICKET = "mock:" + FOURNISSEUR_GET_AUTHENTIFICATION_TICKET;
// Mock result
private final static String MOCK_RESULT = "mock:result";
//Data
private final static String BODY = "Content of the body";
#Override
protected RoutesBuilder createRouteBuilder() {
return routeGetAuthentificationTicket;
}
#Before
public void setContextRoute() throws Exception {
context.getRouteDefinitions().get(0).adviceWith(context, new AdviceWithRouteBuilder() {
#Override
public void configure() throws Exception {
mockEndpointsAndSkip("activemq:IN");
weaveAddLast().to(MOCK_RESULT);
}
});
}
#Test
public void getAuthentificationTicket() throws InterruptedException {
final MockEndpoint resultEndpoint = context.getEndpoint(MOCK_FOURNISSEUR_GET_AUTHENTIFICATION_TICKET, MockEndpoint.class);
context.createProducerTemplate().sendBody(FOURNISSEUR_GET_AUTHENTIFICATION_TICKET, BODY);
resultEndpoint.assertIsSatisfied();
final Object result = context.createProducerTemplate().requestBody(FOURNISSEUR_GET_AUTHENTIFICATION_TICKET, BODY);
assertNotNull(result);
}}
Thanks for your time

How can I get a list of instantiated beans from Spring?

I have several beans in my Spring context that have state, so I'd like to reset that state before/after unit tests.
My idea was to add a method to a helper class which just goes through all beans in the Spring context, checks for methods that are annotated with #Before or #After and invoke them.
How do I get a list of instantiated beans from the ApplicationContext?
Note: Solutions which simply iterate over all defined beans are useless because I have many lazy beans and some of them must not be instantiated because that would fail for some tests (i.e. I have a beans that need a java.sql.DataSource but the tests work because they don't need that bean).
For example:
public static List<Object> getInstantiatedSigletons(ApplicationContext ctx) {
List<Object> singletons = new ArrayList<Object>();
String[] all = ctx.getBeanDefinitionNames();
ConfigurableListableBeanFactory clbf = ((AbstractApplicationContext) ctx).getBeanFactory();
for (String name : all) {
Object s = clbf.getSingleton(name);
if (s != null)
singletons.add(s);
}
return singletons;
}
I had to improve it a little
#Resource
AbstractApplicationContext context;
#After
public void cleanup() {
resetAllMocks();
}
private void resetAllMocks() {
ConfigurableListableBeanFactory beanFactory = context.getBeanFactory();
for (String name : context.getBeanDefinitionNames()) {
Object bean = beanFactory.getSingleton(name);
if (Mockito.mockingDetails(bean).isMock()) {
Mockito.reset(bean);
}
}
}
I am not sure whether this will help you or not.
You need to create your own annotation eg. MyAnnot.
And place that annotation on the class which you want to get.
And then using following code you might get the instantiated bean.
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false);
scanner.addIncludeFilter(new AnnotationTypeFilter(MyAnnot.class));
for (BeanDefinition beanDefinition : scanner.findCandidateComponents("com.xxx.yyy")){
System.out.println(beanDefinition.getBeanClassName());
}
This way you can get all the beans having your custom annotation.
applicationContext.getBeanDefinitionNames() does not show the beans which are registered without BeanDefinition instance.
package io.velu.core;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
#Configuration
#ComponentScan
public class Core {
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(Core.class);
String[] singletonNames = context.getDefaultListableBeanFactory().getSingletonNames();
for (String singleton : singletonNames) {
System.out.println(singleton);
}
}
}
Console Output

As you can see in the output, environment, systemProperties, systemEnvironment beans will not be shown using context.getBeanDefinitionNames() method.
Spring Boot
For spring boot web applications, all the beans can be listed using the below endpoint.
#RestController
#RequestMapping("/list")

#Autowired
private ApplicationContext applicationContext;
#GetMapping("/beans")

String[] registeredBeans() {
return printBeans();

for (String singleton : singletonNames) {
System.out.println(singleton);
}
return singletonNames;

I've created a gist ApplicationContextAwareTestBase.
This helper class does two things:
It sets all internal fields to null. This allows Java to free memory that isn't used anymore. It's less useful with Spring (the Spring context still keeps references to all the beans), though.
It tries to find all methods annotated with #After in all beans in the context and invokes them after the test.
That way, you can easily reset state of your singletons / mocks without having to destroy / refresh the context.
Example: You have a mock DAO:
public void MockDao implements IDao {
private Map<Long, Foo> database = Maps.newHashMap();
#Override
public Foo byId( Long id ) { return database.get( id ) );
#Override
public void save( Foo foo ) { database.put( foo.getId(), foo ); }
#After
public void reset() { database.clear(); }
}
The annotation will make sure reset() will be called after each unit test to clean up the internal state.
Using the previous answers, I've updated this to use Java 8 Streams API:
#Inject
private ApplicationContext applicationContext;
#Before
public void resetMocks() {
ConfigurableListableBeanFactory beanFactory = ((AbstractApplicationContext) applicationContext).getBeanFactory();
Stream.of(applicationContext.getBeanDefinitionNames())
.map(n -> beanFactory.getSingleton(n))
// My ConfigurableListableBeanFactory isn't compiled for 1.8 so can't use method reference. If yours is, you can say
// .map(ConfigurableListableBeanFactory::getSingleton)
.filter(b -> Mockito.mockingDetails(b).isMock())
.forEach(Mockito::reset);
}

ClassCastException when using embedded glassfish for unit tests

I'm running some unit tests on some EJBS via maven and an embedded glassfish container. One of my tests works, but all subsequent attempts to test a different EJB result in the same error:
java.lang.ClassCastException: $Proxy81 cannot be cast to
Followed by whatever bean I'm attempting to test. I'm confident my setup is good since, as I say, one of my beans can be tested properly.
Examples of workiing code:
#Stateful
public class LayoutManagerBean implements LayoutManager {
private final Log LOG = LogFactory.getLog(LayoutManagerBean.class);
public List<Menu> getMenus(User currentUser) {
...
}
}
#Local
public interface LayoutManager {
public List<Menu> getMenus(User user);
}
And the test:
public class LayoutManagerTest {
private static EJBContainer ejbContainer;
private static Context ctx;
#BeforeClass
public static void setUp() {
ejbContainer = EJBContainer.createEJBContainer();
ctx = ejbContainer.getContext();
}
#AfterClass
public static void tearDown() {
ejbContainer.close();
}
#Test
public void getMenus() {
LayoutManager manager = null;
try {
manager = (LayoutManager) ctx.lookup("java:global/classes/LayoutManagerBean!uk.co.monkeypower.openchurch.core.layout.beans.LayoutManager");
} catch (NamingException e) {
System.out.println("Failed to lookup the gosh darned bean!");
}
assertNotNull(manager);
//Menu[] menus = manager.getMenus();
//assertTrue(menus.length > 1);
}
}
And an example of a failure:
#Singleton
public class OpenChurchPortalContext implements PortalContext {
private Set<PortletMode> portletModes = Collections.emptySet();
private Set<WindowState> windowStates = Collections.emptySet();
private Properties portalProperties = new Properties();
public OpenChurchPortalContext() {
portletModes.add(PortletMode.VIEW);
portletModes.add(PortletMode.HELP);
portletModes.add(PortletMode.EDIT);
portletModes.add(new PortletMode("ABOUT"));
windowStates.add(WindowState.MAXIMIZED);
windowStates.add(WindowState.MINIMIZED);
windowStates.add(WindowState.NORMAL);
}
...
}
And the test:
public class OpenChurchPortalContextTest {
private static EJBContainer ejbContainer;
private static Context ctx;
#BeforeClass
public static void setUp() {
ejbContainer = EJBContainer.createEJBContainer();
ctx = ejbContainer.getContext();
}
#AfterClass
public static void tearDown() {
ejbContainer.close();
}
#Test
public void test() {
OpenChurchPortalContext context = null;
try {
context = (OpenChurchPortalContext) ctx.lookup("java:global/classes/OpenChurchPortalContext");
} catch (NamingException e) {
System.out.println("Failed to find the bean in the emebedded jobber");
}
assertNotNull(context);
Set<PortletMode> modes = (Set<PortletMode>) context.getSupportedPortletModes();
assertTrue(modes.size() > 1);
Set<WindowState> states = (Set<WindowState>) context.getSupportedWindowStates();
assertTrue(states.size() > 1);
}
}
Any ideas as to why this may not be working?
You often get this problem if you are proxying a class, not an interface. Assuming that it's this line which is failing:
context = (OpenChurchPortalContext) ctx.lookup("java:global/classes/OpenChurchPortalContext");
OpenChurchPortalContext is a class, but it is being wrapped by a proxy class to implement the EJB specific functionality. This proxy class isn't a subclass of OpenChurchPortalContext, so you're getting a ClassCastException.
You aren't getting this with the first example, because the LayoutManager is an interface.
LayoutManager manager = null; // INTERFACE, so it works
try {
manager = (LayoutManager) ctx.lookup("java:global/classes/LayoutManagerBean!uk.co.monkeypower.openchurch.core.layout.beans.LayoutManager");
} catch (NamingException e) {
System.out.println("Failed to lookup the gosh darned bean!");
}
First, you can test to see if this is really your problem, change context to be a PortalContext not OpenChurchPortalContext:
PortalContext context = null;
try {
context = (PortalContext) ctx.lookup("java:global/classes/OpenChurchPortalContext");
} catch (NamingException e) {
System.out.println("Failed to find the bean in the emebedded jobber");
}
If your problem really is the Proxy, then the above code should work. If this is the case, you have two potential solutions:
When you do the ctx.lookup, always use an interface. This can be a bit of a pain, because you need to define an interface specifically for each EJB.
You may be able to configure your EJB container to proxy the classes instead of just the interfaces, similar to proxyTargetClass for Spring AOP. You'll need to check with the documentation for your container for that.
Your singleton EJB has a default local business interface by means of implementing PortalContext interface. The test client should know it only by its business interface, and the actual bean class (OpenChurchPortalContext) should not be referenced directly by the client. So the fix is to look it up by its business interface PortalContext.
