Struts2 & Spring error: No qualifying bean of type found for dependency
I've found two solutions for this problem. Since I am using Java configuration for Spring, I had to ensure that my contextConfigLocation was set properly. I am using a jar file that contains beans with Spring stereotypes, so I had to ensure that the jar file was being properly built in eclipse. When building the jar file, I had to ensure that the Add Directory entries options was checked. These two steps solved this problem. I hope this helps!

Spring Autowire fails with No qualifying bean of type found for dependency error
Change @Service("CommonSQLService") to @Service("commonSQLService") or you can just use @Service if you're not implementing the CommonSQLService interface anywhere else.

getting error No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined: expected single matching bean but found 2
I had the same issue today. Solved it doing the following: First I've added the parameter unitName to @PersistenceContext to both entity manager properties: @PersistenceContext(unitName="appPU") @Qualifier(value = "appEntityManagerFactory") private EntityManager appEntityManager; @PersistenceContext(unitName="managerPU") @Qualifier(value = "managerEntityManagerFactory") private EntityManager managerEntityManager; And in my configuration file I've added a property persistenceUnitName to my bean definitions: <bean id="appEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource1" /> <property name="persistenceUnitName" value="appPU" /> <property name="packagesToScan" val

Lazy init an injected bean dependency (Spring 3)
You can't really do it like that. Like Sotirios said, Spring needs to instantiate it to inject it into ClassA. You probably can do it manually with the application context. Something like : public class ClassA { @Inject private ApplicationContext appContext; private ClassB classB; //Bean will be instanciated when this method is called public ClassB getClassB() { if (classB == null) { classB = appContext.getBean(ClassB.class); } return classB; } } And then use the getter to access the object.

Your application context and servlet context are component scanning over the same packages.

Spring Testing - Inject mocked bean with nested bean dependencies
You could use standalone mockMvc if you do want to unit test the controller. private MockMvc mockMvc; private SomeController controller = new SomeController(); @Mock private ResourceAdminService resourceAdminService; @Before public void setup() throws Exception { controller.setResourceAdminService(resourceAdminService); this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build(); } If you still want to setup an ApplicationContext, but it's too annoying with the DI. Maybe you'll interested in this article(http://java.dzone.com/articles/how-use-mockstub-spring). But the Strategy C:Dynamic Injecting will rebuild an ApplicationContext per test which could slow you tests if you have too many @Test methods.

Concurrency control with method invocation in EJB bean vs. Spring bean
EJB declarative concurency management applies only to singleton session beans, see javax.ejb.ConcurrencyManagement API.

As for Spring beans concurrency is not managed by container, programmers themselves should take care of it.

How can I access Spring bean from Message-driven bean in JBoss AS 7
A static holder for the context is not really a good idea. To make your beans available to other applications in a Java EE environment, you should consider making use of JNDI. Unfortunately, there is no plain JNDI exporter available out of the box, but it's fairly easy to write one yourself, as shown in this blog post: http://maestro-lab.blogspot.ro/2009/01/how-to-export-spring-managed-bean-to.html There is however a JndiRmiServiceExporter that you may want to look at. Once your beans are bound to names in JNDI, they can be referenced using standard CDI in your message bean without worrying about class loading issues.

When to declare a spring bean as private static when the bean is singleton?
If by declaring the bean as static, you mean something like @Bean public static MyBean myBean() { return new MyBean(); } then the benefit of this is to have your bean generated before the instance method beans. You would use this for example with a BeanFactoryPostProcessor which states: Application contexts can auto-detect BeanFactoryPostProcessor beans in their bean definitions and apply them before any other beans get created. The Spring Java configuration way for these to be auto-detected and initialized before the rest of your beans is to declare and initialize them with static methods. For example, @Bean public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() { return new PropertySourcesPlaceholderConfigurer(); } Spring will de

No property show found for type in spring data
I think the problem is that you wrote this query : @Query("select c from Category c") Which should be : @Query("select * from Category c") The error is probably caused by the Spring Data JPA framework, because if you give it a wrong request, it will probably try to generate a request based on the method name, but in this case, your method name should be "findAll". Moreover, the findAll() method is already given by the Spring Data JPA framework thanks to the CRUDRepository interface.

Spring bean scope as the class of the bean its autowired
U can use prototype scope. Then it will inject new instance of Executor when the Bean is constructed. So Executor starts its lifecycle when the bean is created. scoped-proxy=target-class creates CGLIB wrapper around your bean. So other beans holds reference only to this wrapper, and the right bean with right scope is dynamically injected into this wrapper. i.e. you don't hold very old expired request scoped bean in your session scoped bean, probably injected when the session was created . Instead new bean for current request is injected every time new request is created. This way you can access beans whith shorter life from beans with longer life i.e. your request scoped bean from your session scoped bean.

Can a bean be a value to another bean in the Spring Framework?
You can reference a bean like your dataSource. Your class should have a member that can hold the dataSource: package mypackage; public class MyBean { private DataSource dataSource; public void setDataSource(DataSource dataSource) { this.dataSource = data.Source; } } Then you can inject the dataSource bean into this bean: <beans> <bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource"> <!-- set properties --> </bean> <bean id="myBean" class="mypackage.MyBean"> <property name="dataSource" ref="dataSource"/> </bean> </beans> That's it.

How to inject a JSF bean into a spring bean
If you are using Spring MVC, you can make your "bean" a Model Attribute, then have it auto-loaded into session using a combination of annotations on the Controller, handler methods, and a method that creates an instance of your bean. Your controller would look something like this: @Controller @SessionAttributes({"myBean"}) @RequestMapping("/myPath") public class MyController { @RequestMapping("/myPath2") public String myHandler(@ModelAttribute("myBean") MyBean myBean) { // ...do stuff, return view } @ModelAttribute("myBean") MyBean createMyBean() { // Create and init an instance return new MyBean(); } } You will get a MyBean magically created for you whenever there isn't one, and any time you update the Model (or ModelAndView) with "myBean", it will also get ma

ThreadPoolExecutor Future Task -exception with spring bean injection-spring-beans-2.0
The issue isn't with anything coming from java.util.concurrent or weblogic. What weblogic is telling you is that one of its registered threads has been waiting longer then 10 minutes for the get() to return. So why hasn't it returned? That is because the Callable you submitted has not yet returned. You should check the callable you submit to the executor and find out why that is still in the call() method. For instance, if I write something like Weblogic-Thread-1 Future f= e.submit(new Callable(){ public Object call(){ Thread.sleep(700000); return null; } }); Weblogic-Thread-2 f.get(); //will sit here and suspend for 700 seconds So you need to see why the task you submitted has not yet completed.

Spring JSF integration: how to inject a Spring component/service in JSF managed bean?
@ManagedBean vs @Controller First of all, you should choose one framework to manage your beans. You should choose either JSF or Spring (or CDI) to manage your beans. Whilst the following works, it is fundamentally wrong: @ManagedBean // JSF-managed. @Controller // Spring-managed. public class BadBean {} You end up with two completely separate instances of the very same managed bean class, one managed by JSF and another one managed by Spring. It's not directly clear which one would actually be used in EL when you reference it as #{someBean}. If you have the SpringBeanFacesELResolver registered in faces-config.xml, then it would be the Spring-managed one, not the JSF-managed one. If you don't have that, then it would be the JSF-managed one. Also, when you declare a JSF managed bean spec

AspectJ and NoSuchBeanDefinitionException at least 1 bean which qualifies as autowire candidate for this dependency
from http://docs.spring.io/spring/docs/3.1.1.RELEASE/spring-framework-reference/html/aop.html Spring AOP uses either JDK dynamic proxies or CGLIB to create the proxy for a given target object. (JDK dynamic proxies are preferred whenever you have a choice). If the target object to be proxied implements at least one interface then a JDK dynamic proxy will be used. All of the interfaces implemented by the target type will be proxied. If the target object does not implement any interfaces then a CGLIB proxy will be created. If you want to force the use of CGLIB proxying (for example, to proxy every method defined for the target object, not just those implemented by its interfaces) you can do so. .... To force the use of CGLIB proxies set the value of the prox

Issue in understanding the Spring Bean Scopes Vs Spring web flow Session Scopes
You are confusing yourself with objects and beans. For each request, will it create a new Student Object or Spring container will create only once? The functioning of Spring is purely using beans. When you declare a something like a @Component, it's just an annotation that tells Spring that the part you've declared as a component is either Model or View or Controller i.e. a component of MVC. When you say something like @Scope=singleton, it tells Spring that only a single object instance can access the bean. Let me make it more clear. Say you and I are objects and a strawberry candy is a bean. So if you have the candy. I cannot take it from you. Meaning only one of us can have that candy. It's the same thing with singleton scope. Hope I made things simpler.. :)

Class does not have a public default constructor. The code in the public default constructor threw an exception. Based on the code provided so far, and assuming that you're 100% certain that you're running the code you think you're running, then that can only be cause #1 or #2.

I don't think Dagger can resolve this your activity tries to get injected twice, once with the activity-level graph, once with the application-level graph Here's what I did to get it to work: in ScbeHelper: remove the @Inject annotation in BaseActivity: remove ((protoApp)getApplication()).inject(this); in ActivityModule: remove your provideActivity method (it's not going to be used anymore), and add the following method: @Provides @Singleton ScbeHelper provideScbeHelper() { return new ScbeHelper(activity); } What this does is it provides your ScbeHelper with the context it needs, but leaves only 1 annotati

From the spring specs, there are five types of bean scopes supported : 1. singleton(default*) Scopes a single bean definition to a single object instance per Spring IoC container. 2. prototype Scopes a single bean definition to any number of object instances. 3. request Scopes a single bean definition to the lifecycle of a single HTTP request; that is each and every HTTP request will have its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext. 4. session Scopes a single bean definition to the lifecycle of a HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext. 5. global session Scopes a single bean definition to the

Spring bean getting confused
The behavior is expected, this is because you have two beans with the exact same name info and the one defined later(in A) is the one which gets created at runtime. The behavior is same as what would have happened with the beans defined using xml. How this happens is best explained by understanding the internals of Spring @Configuration which is explained with the Spring documentation here - http://static.springsource.org/spring-framework/docs/3.2.3.RELEASE/spring-framework-reference/html/beans.html#beans-java-further-information-java-config. In short, even if you call info() method directly in AConfig, it is not actually invoking the method on the real AConfig instance, instead it is invoked on a proxy, which has the logic to make sure that the correct bean instance is returned.
