I need help!
so the following code works for me (Pure JUnit code)
#RunWith(SpringJUnit4ClassRunner.class)
#WebAppConfiguration
#ContextConfiguration("classpath:/importMasterConfig.xml")
public class FeatureWrittenInJavaUsingSteps {
#Before()
public void setup(){
/*do something*/
}
#After
public void tearDown()
{
/*Do something*/
}
#Autowired
ItemServiceController service;
#Test
public void callingStepFunctionsExample(){
ItemServiceControllerTestsSteps steps = new ItemServiceControllerTestsSteps(service);
steps.I_prepare_a_X_item_for_the_X_dealer("only images and pricing", "furniture");
steps.I_perform_the_X_inventory_service_call("createItem");
steps.I_should_get_the_X_response_code("200");
steps.the_inventory_service_response_result_should_be_a_X_object("Vertical Item");
}
}
However, when I try to run this code using the Cucumber Feature, it can't seem to build correctly. I am assuming I am setting up the project wrong.
Here is my Step code:
#ContextConfiguration("classpath:cucumber.xml")
public class ItemServiceControllerTestsSteps {
//Common variables across steps - currently only local.
private VerticalItem itemToCreate;
private ServiceResponse response;
//Step specific variables.
#Autowired
private ItemServiceController itemService;
public ItemServiceControllerTestsSteps(ItemServiceController service){
itemService = service;
}
#Before()
public void setup(){/*Do something*/}
#After()
public void tearDown(){/*Do Something*/}
#Given("^I prepare a \"(.*)\" item for the \"(.*)\" dealer$")
public VerticalItem I_prepare_a_X_item_for_the_X_dealer(String itemType, String dealerType){ //Step function and factory in one.
/*Do stuff*/}
#When("^I perform the \"(.*)\" inventory service call$")
public void I_perform_the_X_inventory_service_call(String actionType){
/*Do Stuff*/}
#Then("^I should get the \"(.*)\" response code$")
public void I_should_get_the_X_response_code(String codeType){/*Do stuff*/}
#Then("^the inventory service response result should be a \"(.*)\" object$")
public void the_inventory_service_response_result_should_be_a_X_object(String expectedClassType){ /*Do Stuff*/}
}
Here is my cucumber.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="cucumber.runtime.java.spring stepDefinitions"/>
<context:annotation-config/>
<import resource="classpath:importMasterConfig.xml"/>
</beans>
Finally here is my Runner Class:
#RunWith(Cucumber.class)
#CucumberOptions(plugin = {"pretty", "rerun:rerun.txt", "html:target/local-html-report/"},
glue = "stepDefinitions.ItemServiceControllerTestsSteps")
public class CucumberRunner {}
If someone can please enlighten me why the JUnit runner works and the cucumber one doesn't I would be a very happy camper!
In the above code, I did a few things wrong but lets cover the big ones.
1) My Glue code String was incorrect, I need to pass in the package name, not the file name (should have been just stepDefinitions)
2) I was using Spring 3 instead of Spring 4 with Cucumber 1.2.2 - The latest Cucumber requires Spring 4.
The other stuff wasn't actually related to Spring and Cucumber.
Step definitions should be instance methods on the step definitions classes, and not class (static) methods.
Step definitions classes are instantiated (on demand) for each scenario, so no state should be leaked between scenarios.

I I am very new to spring boot and only have been working with it for a couple of days, so I am also very confused about this project (which is not my own). I am supposed to write tests with MockMvc for the rest controller, however each test with MockMvc only returns the status code 200 although it should be a 404.
Here is one of the tests:
#WebMvcTest(ObjectController.class)
#SpringJUnitConfig(TestConfig.class)
public class MvcTest {
#Autowired
MockMvc mockMvc;
#Test
public void shouldReturn404() throws Exception {
mockMvc.perform(MockMvcRequestBuilders.get("/obj/123"))
.andExpect(MockMvcResultMatchers.status().is(HttpStatus.NOT_FOUND.value()));
}
}
This is my rest controller I would like to test.
#RestController
#RequestMapping("obj")
public class ObjectController {
#Autowired
MyClass myClass;
#GetMapping()
public List<MyObject> findAll() {
List<MyObject> objList;
objList = myClass.getObjects();
return objList;
}
#GetMapping("/{id}")
public MyObject findById(#PathVariable String id) {
for (MyObject obj : myClass.getObjects()) {
if (obj.getId().equals(id))
return obj;
}
return null;
}
}
Then there is this class:
public class MyClass {
private List<MyObject> objList = new ArrayList<MyObject>();
public MyObject addObject(MyObject obj) {
objList.add(obj);
return obj;
}
public void setObjects(List<MyObject> objList) {
this.objList = objList;
}
public synchronized List<MyObject> getObjects() {
return objList;
}
}
There is an xml file that belongs to the class looking like this which can be found in the resource folder:
<?xml version='1.0' encoding='ISO-8859-1'?>
<beans xmlns='http://www.springframework.org/schema/beans'
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns:context='http://www.springframework.org/schema/context'
xsi:schemaLocation='http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd'>
<bean id='MyClass' class='it.is.some.path.MyClass'>
<property name='objList'>
<list>
<ref bean='[R01] Object1' />
</list>
</property>
</bean>
</beans>
The referenced beans can be found in separate files under resources too, in a sub folder called 'objList' and look like this:
<?xml version='1.0' encoding='ISO-8859-1'?>
<beans xmlns='http://www.springframework.org/schema/beans'
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns:context='http://www.springframework.org/schema/context'
xsi:schemaLocation='http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd'>
<bean id='[R01] Object1' class='this.is.some.path.MyObject'>
<property name='id' value='123' />
</bean>
</beans>
The myclass.xml as well as the folder with all xmls of the objects are imported via #ImportResource in the Application class.
And then there is
public class MyObject {
public String id = RandomStringUtils.randomAlphanumeric(5);
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
am sorry for the lengthy explanation but I have been spending two days now trying to figure out how to get MockMvc running and I feel like I am completely stuck. I would be very, very grateful if anybody could help out.
I assume 200 is the correct response as you have a mapping for /obj/{id} where {id} is a placeholder for any path variable like 123 in /obj/123.
Even though your controller returns null from a code perspective, Spring won't map this automatically to a 404 not found if this is what you would expect.
So you can literally try it with every path variable, you'll always get HTTP 200 because there wasn't any exception and the DisptacherServlet could properly route the HTTP request to a controller mapping. HTTP 200 is the default response code if you don't specify anything.
If you want your controller endpoint to return 404 when your MyObject is null, you have to be more explicit about this, e.g.:
#GetMapping("/{id}")
public ResponseEntity<MyObject> findById(#PathVariable String id) {
for (MyObject obj : myClass.getObjects()) {
if (obj.getId().equals(id))
return ResponseEntity.ok(obj);
}
return ResponseEntity.status(HttpStatus.NOT_FOUND).body(null);
}
I've seen a hundred examples of this:
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
#SpringBootApplication
#ImportResource("classpath:applicationContext.xml")
public class MySpringBootApplication {
public static void main(String[] args) {
SpringApplication.run(MySpringBootApplication.class, args);
}
}
And I have been on a rabbit trail for many hours now.
I am building a framework....and I need load (a handful of dependencies, not all of them...) from the xml dependency injection file (aka, "beans") :
applicationContext.xml
and I need to name to be dynamic, not hard coded.
String myValue = "DefaultEnvVarValue";
String envValue = System.getenv("MYENVVARIABLENAME");
if (null != envValue )
{
myValue=envValue;
}
String topLevelAppContextFileName = "applicationContext." + myValue + ".xml";
Without springboot, I would do this:
ApplicationContext context = new ClassPathXmlApplicationContext(topLevelAppContextFileName);
Is there a way to pull this off with SpringBoot?
I found PropertySourcesPlaceholderConfigurer for property files, but cannot find anything for the dependency injection.
Sidenote:
Before I get a "xml bad" comment, most of my dependencies are annotation based. But I'm making a framework for others to use, and therefore I need a handful of them to be xml-driven.....aka, I have a legit reason to have some of the DI be xml driven.
This could work -
Config
public class DemoApplicationContextInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
#Override
public void initialize(ConfigurableApplicationContext ac) {
ac = new ClassPathXmlApplicationContext(topLevelAppContextFileName);
}
}
Main
public static void main(String args[]) {
new SpringApplicationBuilder(Application.class)
.initializers(new DemoApplicationContextInitializer())
.run(
}
For future readers, I ended up doing this:
#SpringBootApplication
#ImportResource({"classpath*:applicationContext.xml"})
public class MySpringBootApplication {
public static void main(String[] args) {
try {
URL resource = MySpringBootApplication.class.getResource("/applicationContext.xml");
if (null == resource || StringUtils.isBlank(resource.getPath())) {
throw new FileNotFoundException("applicationContext.xml not found. The entry dependency injection file must be applicationContext.xml");
}
org.springframework.context.ConfigurableApplicationContext applicationContext = SpringApplication.run(MySpringBootApplication.class, args);
And then I put the "dynamic" part in the inside applicationContext.xml file.
Note the ":" delimiter that will allow a default value if the environment variable does not exist.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util.xsd">
<import resource="projectContext.${MYENVVARIABLENAME:DefaultEnvVarValue}.xml"/>
That was simpler to implement, even though I technically have 2 files, instead of one.
So if the environment variable does not exist, it will default to importing the second file called:
projectContext.DefaultEnvVarValue.xml
Spring Insight documentation states:
A trace represents a thread of execution. It is usually started by an HTTP request but can also be started by a background job
My application architecture style is one of queues running in the background that I'd like to instrument as well. However, I can't figure out how to get Spring Insight to instrument these calls initiated by queued message. I.e. I'd like to instrument the trace after a message is read off of the queue.
How can I ensure Insight instruments these background jobs?
I ended up creating an aspect that targets all of the Command Handlers. It extends the AbstractOperationCollectionAspect, implements the collectionPoint aspect passing in the Handler as an argument to use when it implements the createOperation method.
I.e.
public aspect CommandHandlerOperationCollectionAspect extends AbstractOperationCollectionAspect
{
public pointcut collectionPoint():
execution(* com.xtrac.common.core.handler.ThreadedHandler.HandlerRunnable.executeActorHandler(com.xtrac.common.core.handler.Handler,java.lang.Object));
protected Operation createOperation(JoinPoint jp)
{
Object[] args = jp.getArgs();
com.xtrac.common.core.handler.Handler handler = (Handler) args[0];
Operation operation = new Operation()
.type(XTRACOperationType.COMMAND_HANDLER)
.label(handler.getClass().getSimpleName())
.sourceCodeLocation(getSourceCodeLocation(jp));
return operation;
}
#Override
public String getPluginName()
{
return HandlerPluginRuntimeDescriptor.PLUGIN_NAME;
}
#Override
public boolean isMetricsGenerator()
{
return true;
}
}
I also implemented an AbstractSingleTypeEndpointAnalyzer to fill out the analyzer:
public class HandlerEndPointAnalyzer extends AbstractSingleTypeEndpointAnalyzer
{
private static final HandlerEndPointAnalyzer INSTANCE=new HandlerEndPointAnalyzer();
private HandlerEndPointAnalyzer() {
super(XTRACOperationType.COMMAND_HANDLER);
}
public static final HandlerEndPointAnalyzer getInstance() {
return INSTANCE;
}
#Override
protected EndPointAnalysis makeEndPoint(Frame handlerFrame, int depth) {
Operation operation = handlerFrame.getOperation();
String resourceLabel = operation.getLabel();
String exampleRequest = EndPointAnalysis.getHttpExampleRequest(handlerFrame);
return new EndPointAnalysis(EndPointName.valueOf(resourceLabel),
resourceLabel,
exampleRequest,
getOperationScore(operation, depth),
operation);
}
being sure to add it as a descriptor:
public class HandlerPluginRuntimeDescriptor extends PluginRuntimeDescriptor {
public static final String PLUGIN_NAME = "handler";
private static final HandlerPluginRuntimeDescriptor INSTANCE=new HandlerPluginRuntimeDescriptor();
private static final List<? extends EndPointAnalyzer> epAnalyzers=
ArrayUtil.asUnmodifiableList(HandlerEndPointAnalyzer.getInstance());
private HandlerPluginRuntimeDescriptor() {
super();
}
public static final HandlerPluginRuntimeDescriptor getInstance() {
return INSTANCE;
}
#Override
public Collection<? extends EndPointAnalyzer> getEndPointAnalyzers() {
return epAnalyzers;
}
#Override
public String getPluginName() {
return PLUGIN_NAME;
}
}

I also created a MethodOperationCollectionAspect to collect some of the web service calls that occur in these handers. This sets it up for a nice display that tells me a lot about what is going on during the hander operation, and how much time it takes. E.g.
This set up a framework for maintaining a monitor on the health of the application if I set up the base line Thresholds for the named handlers
This is very useful because I can then tell if the application is healthy. Otherwise, the endpoints default to <200 ms for healthy.
In an attempt to install my component on karaf I get the following error:
Caused by: org.apache.camel.CamelException: Cannot find any routes with this RouteBuilder reference: RouteBuilderRef[logparserRouteBean]
I've narrowed it down to a conversion error in AbstractBeanFactory using the SimpleTypeConverter as returned by the getTypeConverter().
Given that PerformanceLogRoute extends org.apache.camel.builder.RouteBuilder, how can the convertion fail??
Suggestions, and ideas to any solution is greatly appreciated.

This is what I found at this moment. From what I remember it is identical to what caused the error, but I'll double check in the morning.
I have a problem with my Declarative Services. I have 2 bundles, one is a server provider and another the user interface that consumes the service.
On server side, the implementation is:
public boolean checkUser(){
return true;
}
And the XML file inside OSGi-INF folder:
<component name="ZBService">
<implementation class="service.ZBService" />
<service>
<provide interface="service.IZBService" />
</service>
</component>
On client side, the implementation is:
public class GreetingServiceImpl extends RemoteServiceServlet implements GreetingService{
IZBService zb;
public void setZBService(IZBService eventAdmin) {
this.zb = eventAdmin;
}
public void unsetZBService(IZBService eventAdmin){
if(this.zb == eventAdmin){
this.zb = null;}
}
public boolean greetServer(String input, String input2) throws Exception {
return zb.checkUser();
}
}
And XML file:
<component name="ZBService">
<implementation class="main.java.com.gwt.app.server.GreetingServiceImpl" />
<service>
<provide interface="main.java.com.gwt.app.client.GreetingService"/>
</service>
<reference name="zb" interface="service.IZBService" bind="setZBService" unbind="unsetZBService" cardinality="0..n" policy="dynamic" />
</component>
Also, I have included the tag Service-Component on manifest file and I have deployed the equinox ds bundle that is ACTIVE.
The client is a GWT user interface, then I inject the service reference into server side of GWT. Well, when I deploy the application on Equinox it runs, but when I push the button, I launch an event to call ZBService. I have debugged the application and the error is zb attribute is null. It is to say, the dependence is nos injected. However the services are exposed on Equinox. If I write services on Equinox console, the services are deployed. Then, my conclusion is the error is due to the injection does not perform.
I would like to know if someone knows what is the reason??
Thanks a lot in advance!!
Nice day
EDIT:
I did your suggestions but it doesn't run. I change the component names and condinality/policy. The result is the same --> NullPointerException due to the injection isn't done.
Also I have debug the application to see if the methods bind and/or unbind are called, but they aren't.
The complete class is:
public class GreetingServiceImpl extends RemoteServiceServlet implements GreetingService{
static protected IZBService zb;
public GreetingServiceImpl(){
System.out.println("Constructor GreetingServiceImpl");
}
public IZBService getZb() {
return zb;
}
public void setZb(IZBService zb) {
GreetingServiceImpl.zb = zb;
}
public void unsetZb(IZBService zb) {
GreetingServiceImpl.zb = zb;
}
#Override
protected void service(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// Cache the current thread
Thread currentThread = Thread.currentThread();
// We are going to swap the class loader
ClassLoader oldContextClassLoader = currentThread.getContextClassLoader();
currentThread.setContextClassLoader(this.getClass().getClassLoader());
super.service(req, resp);
currentThread.setContextClassLoader(oldContextClassLoader);
}
public void activate(ComponentContext context) {
System.out.println("Creating new greeter for " + context.getProperties().get("name")
+ ": " + context.getComponentInstance().toString());
}
public void activate() {
System.out.println("Activando la referencia al servicio");
}
public void deactivate(ComponentContext context) {
System.out.println("Deactivating greeter for " + context.getProperties().get("name")
+ ": " + context.getComponentInstance().toString());
}
public boolean greetServer(String input, String input2) throws Exception {
return zb.checkUser();
}
}
And the XML client is:
<?xml version="1.0" encoding="UTF-8" ?>
<scr:component name="serviceZB" xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0">
<implementation class="main.java.com.gwt.app.server.GreetingServiceImpl" />
<!-- <service>
<provide interface="main.java.com.gwt.app.client.GreetingService"/>
</service> -->
<reference name="zb" interface="service.IZBService"
bind="setZb" unbind="unsetZb" cardinality="1..1"
policy="static" />
</scr:component>
Why isn't the service injected if the service is deployed???
Here is a list of things you can try:
First, remove the "static" of zb, that could be the problem.
If you are using Equinox, add the -Dequinox.ds.print=true flag to the VM arguments and see more information about parsing XMLs and so
Of course, add sysouts to setZB and unsetZB :)
Remember that IZBService implementation needs a constructor without arguments
If you are using Equinox use the "list -c" command to obtain information of each component (it's cool because says exactly why a component is not registered).
Set the "inmediate=true" in XMLs to force to inmediatly activation.
You have both components with the same name, , which is kind of awkward when discussing them.
The reference on the client side has: cardinality="0..n" policy="dynamic". Which means it can be activated with zero to n references. Yet your code does not handle this. It seems to expect exactly one reference. Perhaps you should use cardinality="1..1" policy="static".
