Autowiring in servlet

I followed the solution in the following link, and it works fine: Access Spring beans from a servlet in JBoss public class MyServlet extends HttpServlet { @Autowired private MyService myService; public void init(ServletConfig config) { super.init(config); SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this, config.getServletContext()); } }

Can spring @Autowired Map?

You can create an automatically initialized map with keys of your choice using Spring Java configuration: In class annotated with @Configuration annotation: @Autowired private List<ISendableConverter> sendableConverters; @Bean public Map<String, ISendableConverter> sendableConvertersMap() { Map<String, ISendableConverter> sendableConvertersMap = new HashMap<>(); for (ISendableConverter converter : sendableConverters) { sendableConvertersMap.put(converter.getType(), converter); } return sendableConvertersMap; } Than you inject this map … Read more

Exclude subpackages from Spring autowiring?

I’m not sure you can exclude packages explicitly with an <exclude-filter>, but I bet using a regex filter would effectively get you there: <context:component-scan base-package=”com.example”> <context:exclude-filter type=”regex” expression=”com\.example\.ignore\..*”/> </context:component-scan> To make it annotation-based, you’d annotate each class you wanted excluded for integration tests with something like @com.example.annotation.ExcludedFromITests. Then the component-scan would look like: <context:component-scan base-package=”com.example”> … Read more

Injection of autowired dependencies failed;

The error shows that com.bd.service.ArticleService is not a registered bean. Add the packages in which you have beans that will be autowired in your application context: <context:component-scan base-package=”com.bd.service”/> <context:component-scan base-package=”com.bd.controleur”/> Alternatively, if you want to include all subpackages in com.bd: <context:component-scan base-package=”com.bd”> <context:include-filter type=”aspectj” expression=”com.bd.*” /> </context:component-scan> As a side note, if you’re using Spring … Read more

Spring @Autowired on a class new instance

Spring itself offers some functionality for doing auto-wiring in your objects which you created by new or newInstance() or whatever. To use it you need an AutowireCapableBeanFactory which you get by Spring’s normal dependency injection with @Autowired. @Autowired private AutowireCapableBeanFactory autowireCapableBeanFactory; Then you use its autowireBean(Object) method to inject the @Autowired properties into your bean. … Read more

Injecting @Autowired private field during testing

You can absolutely inject mocks on MyLauncher in your test. I am sure if you show what mocking framework you are using someone would be quick to provide an answer. With mockito I would look into using @RunWith(MockitoJUnitRunner.class) and using annotations for myLauncher. It would look something like what is below. @RunWith(MockitoJUnitRunner.class) public class MyLauncherTest … Read more

Inject and Resource and Autowired annotations

The difference between @Inject vs. @Autowire vs. @Resource? @Autowired: spring propriety annotation (as opposed to @Inject and @Resource) that inject a resource by-type, i.e. by the class of by the interface of the annotated field or contractor. In case we have few implementation of an interface or a subclass we can narrow down the selection … Read more

intellij incorrectly saying no beans of type found for autowired repository

I had this same issue when creating a Spring Boot application using their @SpringBootApplication annotation. This annotation represents @Configuration, @EnableAutoConfiguration and @ComponentScan according to the spring reference. As expected, the new annotation worked properly and my application ran smoothly but, Intellij kept complaining about unfulfilled @Autowire dependencies. As soon as I changed back to using … Read more

You can do this by following one of the solutions: Using constructor @Autowired This approach will construct the bean requiring some beans as constructor parameters.

Using Spring 3 autowire in a standalone Java application

Spring works in standalone application. You are using the wrong way to create a spring bean. The correct way to do it like this: @Component public class Main { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext(“META-INF/config.xml”); Main p = context.getBean(Main.class); p.start(args); } @Autowired private MyBean myBean; private void start(String[] args) { … Read more
