I have a task class defined here:
{
#Autowired
private CarPainter carpainter;
private String color;
private Car car;
public CarPainterTask(Car car, String color)
{
this.car = car;
this.color = color;
}
public Car call()
{
if(car.getColor().equals(color))
{
return car;
}
carPainter.paint(car);
return car;
}
}
I want to be able to #Autowired a service into my task class but also be able to put in some parameters
I've tried creating a #Configuration class for my Redisson node
#Bean
public RedissonNode createRedissonWorker()
{
RedissonNodeConfig nodeConfig = new RedissonNodeConfig(redissonClient.getConfig());
nodeConfig.setExecutorServiceWorkers(Collections.singletonMap("carService", 1));
nodeConfig.setBeanFactory(applicationContext);
RedissonNode node = RedissonNode.create(nodeConfig);
node.start();
return node;
}
And having Redisson inject CarPainter bean from Springboot's bean container, but this doesn't work...
Is there a way to achieve what I need here ?
In your createRedissonWorker() method use the BeanFactory instance to pass it to setBeanFactory() instead of the ApplicationContext and it should work just fine.

When trying to use #AutoWire feature with one of StandAlone Application unable to do so instead getting Null Pointer Exception. Please highlight my mistakes if any. Your help is appreciated.
Spring Ver 5.1.5.RELEASE and we're not using any xml config file to tell spring there are annotated classes to look into instead using #ComponentScan or #EnableAutoConfiguration at the top of AppConfig and boost strap the Context from main() class as a first line. But Autowiring works perfectly with internal bean/java classes of jdk(Environment) but not with custom POJO classes. If we're trying to get through getBean method then it works. But I'm trying to avoid creating context everywhere and using getBean() Please Refer below and help me only with your valuable guidelines.
public class ContextMaster {
private static AnnotationConfigApplicationContext appContext;

if (appContext == null) {

factoryBean.setHibernateProperties(props);
factoryBean.setAnnotatedClasses(xx.class, xxxx.class, xxxx.class, xxx.class);

It seems like you didn't put the full code here, because your Good class won't compile this way..
Scenario
I've got a Spring Boot application with a #Configuration annotated Spring configuration class which contains some #Value annotated fields. For testing I want to replace these field values with custom test values.
Unfortunately these test values cannot be overridden using a simple properties file, (String) constants or similar, instead I must use some custom written property resolving Java class (e.g. TargetProperties.getProperty("some.username")).
The problem I have is that when I add a custom PropertySource to the ConfigurableEnvironment within my test configuration, it's already too late because this PropertySource will be added after the e.g. RestTemplate has been created.
Question
How can I override #Value annotated fields within a #Configuration class with properties obtained programmatically via custom Java code before anything else gets initialized?
Code
Production Configuration Class
#Configuration
public class SomeConfiguration {
#Value("${some.username}")
private String someUsername;
#Value("${some.password}")
private String somePassword;
#Bean
public RestTemplate someRestTemplate() {
RestTemplate restTemplate = new RestTemplate();
restTemplate.getInterceptors().add(
new BasicAuthorizationInterceptor(someUsername, somePassword));
return restTemplate;
}
}
Test Configuration Class
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
public class SomeTest {
#SpringBootConfiguration
#Import({MySpringBootApp.class, SomeConfiguration.class})
static class TestConfiguration {
#Autowired
private ConfigurableEnvironment configurableEnvironment;
// This doesn't work:
#Bean
#Lazy(false)
// I also tried a #PostConstruct method
public TargetPropertiesPropertySource targetPropertiesPropertySource() {
TargetPropertiesPropertySource customPropertySource =
new TargetPropertiesPropertySource();
configurableEnvironment.getPropertySources().addFirst(customPropertySource);
return customPropertySource;
}
}
}
You can override properties directly in the #SpringBootTest annotation using the properties parameter:
#SpringBootTest(properties = {"some.username=user", "some.password=pwd"},
webEnvironment = SpringBootTest.WebEnvironment.NONE)
You can use #TestPropertySource
#TestPropertySource(
properties = {
"some.username=validate",
"some.password=false"
}
)
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class ApplicationTest {
//...
}
You can use constructor injection in production cases, which allows it to set the configuration manually:
#Configuration
public class SomeConfiguration {
private final String someUsername;
private final String somePassword;
#Autowired
public SomeConfiguration(#Value("${some.username}") String someUsername,
#Value("${some.password}") String somePassword) {
this.someUsername = someUsername;
this.somePassword = somePassword;
}
...
)
}
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
public class SomeTest {
private SomeConfiguration config;
#Before
public init() {
config = new SomeConfiguration("foo", "bar");
}
}
Is it possible to create spy(mock) object in testing class?
Here is tested class.
#Stateless
#Slf4j
public class UserDao {
#Inject
private TestBean testBean;
public String mock() {
return testBean.mock();
}
public String notMock() {
return testBean.notMock();
}
}
TestBean code
#Stateless
#Slf4j
public class TestBean {
public String notMock() {
return "NOT MOCK";
}
public String mock() {
return "IMPLEMENTED MOCK";
}
}
Here's my test
#RunWith(Arquillian.class)
public class UserDataTest {
#Rule
public ExpectedException thrown = ExpectedException.none();
#Inject
private UserDao userDao;
#Deployment
protected static Archive createWar() {
File[] dependencies = Maven.configureResolver()
.withRemoteRepo("nexus-remote", "http://maven.wideup.net/nexus/content/groups/public/", "default")
.withRemoteRepo("nexus-release", "http://maven.wideup.net/nexus/content/repositories/releases/", "default")
.resolve(
"org.slf4j:slf4j-simple:1.7.7",
"eu.bitwalker:UserAgentUtils:1.15",
"org.mockito:mockito-all:1.10.8"
).withoutTransitivity().asFile();
return ShrinkWrap
.create(WebArchive.class, "pass.jpa.war")
.addAsWebInfResource("jbossas-ds.xml")
.addAsWebInfResource("jboss-deployment-structure.xml")
.addAsLibraries(
PassApiDeployments.createDefaultDeployment(),
PassUtilLibrary.createDefaultDeployment(),
PassJpaDeployments.createDefaultDeployment()
).addAsLibraries(dependencies);
}
#Test
public void testMock() {
assertEquals("MOCK", userDao.mock());
}
#Test
public void testNotMock() {
assertEquals("NOT MOCK", userDao.notMock());
}
}
I'd like to create a spy object on TestBean to change result on method test() of this bean.
So is it possible to create TestBean spy in UserDao.
I solve some problems through producer like this.
#Singleton
public class MockFactory {
#Produces
#ArquillianAlternative
public TestBean getTestBean() {
return when(mock(TestBean.class).mock()).thenReturn("MOCK").getMock();
}
}
But in this example I need create on Bean completely on my own. And if it is bean with additional dependencies and thus i will manage all dependencies.
As far as I know, its not possible to use a mocking framework in combination with arquillian ...
I haven't used it myself, but this Arquillian extension seems to be specifically designed to support Mockito Spy objects in an Arquillian test: https://github.com/topikachu/arquillian-extension-mockito/
Hi I am trying to change a code example found here
http://imar.spaanjaars.com/577/aspnet-n-layered-applications-implementing-a-repository-using-ef-code-first-part-5
In his example he uses structure map, when I converted it to windsor I can get it to work with the one repository using the following.
container.Register(Component.For<IUnitOfWorkFactory>().ImplementedBy<EFUnitOfWorkFactory>(),
Component.For<IUnitOfWork>().ImplementedBy<EFUnitOfWork>(),
Component.For<Model.Repositories.IPeopleRepository>().ImplementedBy<PeopleRepository>().LifestyleTransient());
But what I really want to do is to map all the irepository based interfacees to thier implementation.
Here is the IRepository, T is the entity, K is the prmiary key type
public interface IRepository<T, K> where T : class
{
}
Its implementation Is
public abstract class Repository<T> : IRepository<T, int>, IDisposable where T : DomainEntity<int>
{
}
My controller has the interface IPeopleRepository as a constructor paramerter.
public interface IPeopleRepository : IRepository<Person, int>
{
}
public class PeopleRepository : Repository<Person>, IPeopleRepository
{
}
I want to have one register to register all repositories, something like this, but it wont match and i get the error Service 'Spaanjaars.ContactManager45.Model.Repositories.IPeopleRepository' which was not registered
container.Register(Component.For(typeof(IRepository<,>))
.ImplementedBy(typeof(Repository<>))
.LifestylePerWebRequest());
What am i missing in regards to this? is it because my irepository has 2 generic types?
In order to map all the IRepository based interfaces to their implementations .WithService.AllInterfaces() should be used.
This registration should solve your issue.
container.Register(
Classes.FromThisAssembly()
.BasedOn(typeof(IRepository<,>))
.WithService.AllInterfaces()
.LifestylePerWebRequest());
There are some tests to test it. I claim they are green.
[TestClass]
public class InstallerTest
{
private IWindsorContainer container;
[TestInitialize]
public void Init()
{
container = new WindsorContainer().Install(new Installer());
}
[TestMethod]
public void ResilveTest_ResolvesViaIRepository()
{
// act
var repository = container.Resolve<IRepository<Person, int>>();
// assert
repository.Should().BeOfType<PeopleRepository>();
}
[TestMethod]
public void ResilveTest_ResolvesViaIPeopleRepository()
{
// act
var repository = container.Resolve<IPeopleRepository>();
// assert
repository.Should().BeOfType<PeopleRepository>();
}
}
public class Installer : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(
Classes.FromThisAssembly()
.BasedOn(typeof(IRepository<,>))
.WithService.AllInterfaces()
.LifestylePerThread());
}
}
Im writing a test for an automapper map. One of the destination members in the map requires a value resolver, and that value resolver has service dependencies which are injected. I want to use the real implementation for the resolver (since thats part of the map im testing) but Id like to use mocks for the dependencies the resolver has.
Ofcourse I want to try to avoid using an ioc container for in my tests, but how do I easily resolve my value resolver's dependencies without one?
This is my rather simplified example, in the real case there are several resolvers with sometimes many dependencies, and I really dont like to basically implement my own dependency resolver in my tests. Should I use a lightweight ioc container?
[TestFixture]
public class MapperTest
{
private IMyService myService;
[SetUp]
public void Setup()
{
Mapper.Initialize(config =>
{
config.ConstructServicesUsing(Resolve);
config.AddProfile<MyProfile>();
});
}
public T Resolve<T>()
{
return (T) Resolve(typeof (T));
}
public object Resolve(Type type)
{
if (type == typeof(MyValueResolver))
return new MyValueResolver(Resolve<IMyService>());
if (type == typeof(IMyService))
return myService;
Assert.Fail("Can not resolve type " + type.AssemblyQualifiedName);
return null;
}
[Test]
public void ShouldConfigureCorrectly()
{
Mapper.AssertConfigurationIsValid();
}
[Test]
public void ShouldMapStuff()
{
var source = new Source() {...};
var child = new Child();
myService = MockRepository.GenerateMock<IMyService>();
myService .Stub(x => x.DoServiceStuff(source)).Return(child);
var result = Mapper.Map<ISource, Destination>(source);
result.Should().Not.Be.Null();
result.Child.Should().Be.SameInstanceAs(child);
}
}
public class MyProfile : Profile
{
protected override void Configure()
{
base.Configure();
CreateMap<ISource, Destination>()
.ForMember(m => m.Child, c => c.ResolveUsing<MyResolver>());
}
}
public class MyResolver: ValueResolver<ISource, Destination>
{
private readonly IMyService _myService;
public MyResolver(IMyService myService)
{
_myService = myService;
}
protected override Child ResolveCore(ISource source)
{
return _myService.DoServiceStuff(source);
}
}
}
Here's one solution, but basically its what iv done already:
http://groups.google.com/group/automapper-users/browse_thread/thread/aea8bbe32b1f590a/f3185d30322d8109
The suggestion is to use a service locator which are set up differently depending on test or real implementation.
